the listing for the Corsa is still up, with the sellers details, with the CF in the background, so theres a good excuse to ask about it  https://www.ebay.co.uk/itm/135926508721

Ah, so he didn't sell it as that he knew it had HGF? Was this something you thought it might from the mayo? Or something he deduced from the mayo when in person?

Either way just drive it and see if it consumes any water or mixes. I suspect it'll be fine.

Code reader, depends on the budget. But for just this car, I'd get a ELM327. Look for a v1.5 with a PIC microcontroller in - usually the eBay sellers make a fuss about it. They are the 'proper' ones. As in they're knock offs of genuine (which you can't get anymore) but not the cheapened out version that some sellers now sell.

Get one of the many OBD code scanners  apps on Android. Torque is often cited and also Piston used to be good. No idea if either aren't chocked full of ads now though. Loads of obd scanner apps though. They all only do the basic engine.

If you want to scan more modules on it try this app:

https://play.google.com/store/apps/details?id=com.ScanMyOpelLite.Main

If everything works okay then this is the paid version:

https://play.google.com/store/apps/details?id=com.ScanMyOpel.Main

A lot of bad reviews are going to be from crap ELM327 adapters causing miscommunication.

If you want a universal reader then cheap OBD scanners will do the same as torque/piston/etc - just engine. More expensive (~£100) will do engine/airbag/abs. Even more expensive (>£250) will do all modules like scanmyopel above does on just Opel/vauxhall.

I'd probably start with a elm327 and torque/piston to get the engine error code out. Probably a O2 sensor code, cat efficiency code or maybe even thermostat. Possibly even from not being driven enough and getting to temperature.

I certain on this age corsa you can still do the "pedal test", that should get you a code up in a morse code style flashing the spanner light. You won't clear a light but it's free.  I'd guess the light will turn itself off anyways, coil pack misfire or crank sensor was the usual. 

As Si has said, mayo on cap really common, oil in the coolant isnt alway HGF either if the tank looks murky. These cars can take a surprisingly large amount of abuse and still just not die. They will sound like death but just drag on.

[worldofceri]

Somebody who owns a fit as fuck correctly-engined slidey-doored primrose yellow Bedford CF would not flog you a shagged Corsa.

Some things are just universal truths.

yeah he didn't think there was a head gasket issue

but my guessing is based on the MOT fail before the pass, and then seeing Mayo, he bought it auction or something like that by the sounds of it, between MOT maybe? and well sure the keeper address on the V5 started with "NDA Belvedere Auctions" so make of that what you will!

but yeah there was coolant in there that looked like coolant (orange stuff) maybe a bit low? tho I admit I was struggling to find exactly where the min-max mark was on the coolant bottle! (not because it was dirty or anything I just couldn't find it LOL) and and the level did not seem to change, we did pull over to check just before crossing tower bridge, but we have only done 15 miles or so

thanks for the low down details , are there any IOS versions or equivalents? not really an android household here im afraid! I can find a few reporting "V1.5" IE https://www.ebay.co.uk/itm/365369288121

but not too many that explicitly mentioning having a pic microcontroller (and can that in itself be trusted? LOL)

oh thats handy! ill see about trying that/getting him to try and see what it flashes back! (I am hoping if it is not HGF then it will be something nice and simple like a coil pack or duff sensor thats not too hard to change, that would be nice!)

My old Felicia (Volkswagen AEE 1.6 engine) had constant mayo in the filler cap because it was only used for short runs. 2.3 miles to work and back again was just not enough to burn off all the condensation. As soon as you took it on a decent run it all disappeared. 

We had it nine years and nothing ever happened. Not to the engine anyway. I would suspect the same at least until you've taken it on a decent run. 

[Missy Charm]

That Corsa doesn't look half bad for the money.  Re the creamy oil filler cap, the done thing with a £500 car - if memory serves - is to put the cap back on and completely forget that you ever saw the white substance.  The 'ignore everything and buy another old banger if this one breaks' method of maintenance got me through thousands of trouble-free motoring miles in the old, cheap-car days.

got my brother to do the dance and record the codes 

I found this guide on how to count em but I admit I am struggling to count them myself

https://www.scribd.com/embeds/383840399/content

my brother thinks its

1614

0141

0136 

0136

 

which looking at the guide above would be 

P1614 Wrong Security Code received Immobiliser C-06

0141 is
P0141 O2 Sensor Heater Circuit High Voltage (Bank 1 Sensor 2) C-31
P0141 O2 Sensor Heater Circuit Low Voltage (Bank 1 Sensor 2) C-31

and 0136 would be
P0136 O2 Sensor Circuit High Voltage (Bank 1 Sensor 2) C-32
P0136 O2 Sensor 2 Circuit Voltage Low C-32
P0136 O2 Sensor 2 Open Circuit C-32

 

 

1614 sounds a bit strange to me, if its bitching about the immobiliser, surely it would not go anywhere/it would refuse to start out right?

 

but 0136 and 0141, if its just complaining about the O2 sensor I wonder if thats just down to the hole in the exhaust? because one sensor is just not getting the flow of gasses its meant to as its all going out of a hole instead 

 

but yeah if someone can watch the video and read the code for themselves just to verify things that would be much appreciated

The ex drove a few vauxhalls, the 1.2 corsa and 1.6 meriva had that mayo on the oil cap constantly even with a yearly oil change.

If it's been pootled around London alot/slow short trips it'll be why (she did 7 miles to work then off for 8 hours then 7 miles home etc constantly).

I'd ignore it, keep the oil fresh and if possible take it for a good fast smash up the motorway, even at the speed limit it'll be screaming it's nut off nicely enough to get hot!

I keep saying also : Avoid castrol and in a vauxhall see if you can get GM oil from a dealer.  Certainly solved the same issue with the omega I had.

Can't remember what oil I used to use, but it was probably the sheapest stuff ecp had on offer at the time 😂

I remember on the corsa if the engine chain started sounding loud it was time for a top up. When we part exchanged it I put it to a bit above the max and it sounded beautiful 👌 Front carpets were spotless too as I'd wet vacced them out the day before to dry them out as the brake booster seal was fucked...

Post cat O2 sensor. 

Could be a hole in the exhaust but possibly dead sensor, buggered wiring or dead cat.

My suspicion would be on the sensor at this age. 

Clear codes and see if it comes back. 

[egg]

Two of my ecotec cars also had mayo.

Both also died spectacularly. One dropping all its oil on the M2.

suitably budget code-reader-scanner-thingy (technical term) has been order,  fingers crossed it doesn't just fire all the air bags the moment I plug it in...

but yeah the MOT mentions a slightly blowing exhaust, and so did the seller, so I suppose at some point we will try n paste that up if possible (why am I getting a sudden sense of deja vu...)

 

 

I suppose I should ask if theres anything else I should know about these Corsa C's? I literally know Zero about em, anyone at least got a link to a owners manual PDF or something? anything I should watch out for?  £500 distress purchase it may be, I may as well try and get a handle of things and make the best of it for my brother  

(and I did managed to get myself added to the insurance policy today, so if I can fit an 8ft fluorescent tube inside, I can very much see myself borrowing it)

[beko1987]

A cheap exhaust shouldn't be that expensive, I remember the Meriva Klarius ones I used to fit were £130ish for the centre section and backbox. If you need an O2 sensor too there's a fair chance it's seized right in, it might be cheaper in both parts and time cost to just buy everything from the flex back and a sensor as cheaply as you can and lob it all on fresh. The front flexi isn't leaking is it? (that's assuming the worst and it's not something simple when you get to look.

Oil/spark plugs/air oil and fuel filter would be a good £50 to spend I guess, especially if it's been barely driven about. 

There's also many reasons an engine would dump all its oil so I wouldn't get too hung up on that 😂 Some vauxhalls have an oil cooler which leak (the ex's 1.8 Zafira leaked for ages although never fully failed. I used to wipe it down before the mot but apparently after we split up and 2 years went by it was dropping well... I've had coil packs go on the meriva (£25 for an ebay unit, it threw codes) as well as the cat starting to shit itself and throw codes. That was fixed each time by me taking it to my work and back for a week each time but I knew it wouldn't last. Luckily it did long after we sold the car to a shifter who drove it until it failed the mot on other things.

Their nice easy cars to work on tbh, and as much they should be given lots of hate I dailied the ex's for over  a year and it was good fun. (my puma was far better going 8 miles on her commute than the 17 for mine on fuel 😂) Driving from Stokenchurch to Marlow via the back road I could wind the little 1.2 up to 70mph (I'd leave at 6am) and hold it there the entire* way (bar the villages) and it'd stick to the road nicely tbh. Was a bit grim on the motorway but we didnt drive it long distance whilst we had it. I think once I smashed it up to Northampton but that's all back roads anyway for me

If the drivers carpet gets wet in the rain the brake booster thing to the body seal is gone. Liveable though with a wet vac. We had the heater matrix clog up too and I had a foul horrible winter with it before taking both matrix feed pipes off and running a hose through both ways, tons of claggy shit came out and heating restored!

The central locking wasn't working when I met her, an unplug and re plug of the ecu fixed that.

Otherwise their very easy to work on, parts cost fuck all and their well documented. I don't think they have many massive ugly points to them, no more than any other car.

You probably should have a drive of it when you can and see if you like it/your spine stays intact. You could borrow it to do less Rev friendly trips... Or fit a towbar to it and get a little trailer...😂🤔

[beko1987]

I remembered an old friends grans corsa c too. This was way before I met the ex, it was a 56 plate and under 2 years old, and an auto 🤮

I didn't drive then but my friend did and he'd borrow it occasionally. It spent its entire life until she probably died (friend turned into a cunt so I ghosted him many years ago) driving probably a 15 mile radius of Knowl Hill in her hands, she used to drive back from her WI meeting brandied out of her skull... "the car knows the way" 😬

We once took it to the same friends parents second house in south Devon, that woke it up 😂 My mates car was broken at the time so she said take hers (she came too but went in her sons/my mates dad's brand new merc ML (had an angry drive with him home from Devon in that once too, we did near crediton to maidenhead faster than was safe... Car felt like a spaceship though as we did 120mph back north at 5.30am... Family argument that I fucking hated every second of, friend fucked off and abandoned me and some others there so we got taken home 😬)

It took 4 of us (17 to 20 year old lads )plus luggage being hot boxed the whole way there fairly well although my friend very quickly gave up trying to be above 80 at all. Was more roomy than whwn we did the same trip in James Fiesta 1.2 (5 door S reg). James didn't smoke and didn't go above 60 (he was a new driver tbh). I recall a trip where my mate had his MG ZT120 and we set off at roughly the same time and we beat James by 3 hours... Us driving incredibly fast got us past an accident on the m5 that James was behind doing 57 on the m4

Hello,
thank you for your reply last week regarding the shock absorbers in my Invacar MK12E.
Maybe it is possible that the weeking ist normal. Think i will drive it like it is.

Here pictures of the car a few days ago.

[LightBulbFun]

Very Awesome to see HEV once more looking resplendent  and very awesome to see that it looks like you did manage to get it registered over there? I think its the first time I have seen an Invacar Mk12E on foreign plates!

[LightBulbFun]

in Corsa news the code reader arrived and by happenstance my brother wanted to pop around with the Corsa to poke at it some more  

 

low and behold the code reader did actually work and find 2 codes, looks like my brother is more proficient at morse-code then I am LOL 

both cleared and the engine light went out, so that was nice!   we will see how long it stays off for, it didn't come on during the drive to halfords and back at least

we did confirm the exhaust backbox is holed/blowing, didn't get a good look at the rest of the exhaust, but we did notice that at least one of the tyres appears to be cracking somewhat

it was notice the day previously the reverse lights dont appear to be functioning, so we gave that a poke but no luck with a new bulb and there does not seem to be any voltage going to it at the connector that plugs into the rear light cluster itself,  I did wonder if it was a fuse, but there did not appear to be any dedicated "reverse lights" fuse listed in the handbook, could it be a duff reverse-light-switch on/in the gearbox or is it more complicated on these modern cars?

and speaking of poking about with a view of giving it a service does anyone have any recommendations on what service items to get? or what the best place to get them from is? (smashing the reg into ECP, it gives me the option of 2 different oil filters of different dimensions right off the bat, so thats helpful*)

You mentioned earlier about pasteing/bodging the back box. Just buy a new one. My Corsa back box (although admittedly a B model) was £46 delivered a couple of weeks ago. The correct exhaust section for your brother's car will be around the same price.

Edit - try Parts in Motion website for exhaust and service parts. They will confirm the part/s are correct if you ask and give them the reg no. They are also on eBay.

Reverse light isn't a testable MOT item on this age. So it could have been broken for years. 

On the C, I can't imagine the circuit will be that complicated. It's around the time when stuff was starting to be "multiplexed" through a body computer but a lot was a physical wire from switch to bulb. 

[SiC]

A quick Google says that the fuse is shared with the cigarette lighter - a bit random wiring but then GM does weird stuff like this. Anyway does that work? Often people accidentally drop coins and such into them due to their position which pops it. 

Otherwise likely the switch on the gearbox or the wiring. 

[Split_Pin]

As long as the front subframe is OK you can't go wrong with one of these. My mum had an 05 Twinport Life for 10 years. They don't really rust apart from the subframe (unlike the earlier B!) although this Nissan unlikely to be an issue if its been a London car .

Don't worry about the mayo under the cap. All GM Family 0 engines I've owned have displayed this and every time it was due to short journeys.  If the oil looks like oil on the dipstick and not chocolate then simply carry on.

If it ever has an oil leak it will 99% be the pressure switch on the very top left of the engine as you face it. £10 and 5 mins with I think a 19mm and it's fixed.

Enjoy!

And autodoc shows up 3 diffrent Mann filters and there seems to be different sizes on them. That's very annoying of GM. Could you be lucky enough to have the oil filter housing marked with the type of filter or to have a service receipt in the car with the type of oil filter used written on it? Alternatively, if you want to be absolutely sure, remove the oil filter lid and look at the oil filter that is there to see if it has a brand and number on it, which it most likely does.

[beko1987]

Or as its ecp, buy all 3, keep all 3 spotless until you know which one you need then return the other 2!

I did this with the xsara when I did the steering rack gaitor. 2 types were listed and I only wanted it all apart once! Kept my greasy mitts away from the one I didn't need and took it back the next week for a refund

Yeah! having had a look at it, it very much is past the bodge it with exhaust paste, theres a hole right next to one of the hangers that looks like it would be a right awkward bastard to try and bodge (although I am sure theres someone on here who would try and do it  ) and there are other places on it where someones obviously attempted/done similar bodges, so I think it is certainly replacement time

there is just the question of is there any holes elsewhere in the exhaust!  thanks for the heads up on the website, looks like according to them the oil filter changed at a certain engine number series/late in 2006, so thats good to know

good to know its not testable! I wasn't sure if it was or was not, or was one of those things where "if fitted its testable, but if its not fitted its not testable" sort of items (like taking Bikes for day time MOT's)

I did tell my brother if it makes him feel better, my car doesn't have reverse lights at all, and he said no it doesn't make him feel better LOL but yeah thats my fears, especially after reading of @RobT's woes with the 406, which is an older car then this!

yeah while we where trying to have a look at the exhaust in the Halfords car park (my brother did manage to fix the floppy rear wiper, and replace its wiper blade) it did seem pretty clean underneath!

sounds suitably Autoshite! I mean theres 2 different oil filters for my car, but its bleedingly obvious which one is which, because ones a Cartridge filter the others a spin on filter LOL

you dont think they will get suspicious if a bloke keeps returning Corsa C parts in an Invacar?

 

 

BTW I suppose a question for @Dave_Q, but whats the situation on getting replacement Key's for a Corsa C like? my brother only got the 1 key and its one of the basic types, not one of the ones with buttons on it, so we are wondering if a replacement one with buttons on it can be got, or at least if a couple more keys could be got? its not even my car and it gives my anxiety knowing theres only 1 key for it LOL  (I *think* someone did note some key related numbers in the little wallet thingy the handbook goes into, theres a radio code in there also which is nice!)

[beko1987]

Re the key, in the book pack is there a business card with a key code on it? That's quite important for vauxhalls iirc.

When the CIM module went in the ex's Zafira we didn't have that code, so any thoughts of doing anything to fix would have started with an expensive trip to somewhere/vauxhall to get the code off the ecu and then you can start...

 

(CIM module sits beind the steering wheel and controlled the horn/lights/audible beeps etc. The horn limped on until the end but the car never had a door or lights on warning buzzer when we had it 😂 A corsa probably doesn't have that so shouldn't be an issue, but I imagine the code is key for any of them. Luckily for the ex the whole exhaust fell off on her and she scrapped the car before it was due to fail it's next mot in the inop horn 🤷)

 

Ecp won't give a toss about refunds as long as you have the receipt and the part isn't used/trashed etc. Always check all parts before leaving too, I've had instances of the wrong part being in the box etc before and it's 95% more annoying when you've gone home, stripped the car down THEN realise
