*actual progress klaxon* 205 Jr 2.0 HDI Build

It turns out I made a dangerous assumption about the ECU, it is in fact a SID801 which it appears isn't really at all easy to remove the immobiliser from. Therefore plan A involving bodgery and gaffer tape is go. At this point I just want it running, so am happy enough to just mount everything in a box in the footwell or something to deal with later. Unfortunately this probably means having to program out the alarm, I think? Maybe just bodge it so all the sensors and switches are permanently in a state of "everything is fine". I think I have a decent amount of time this weekend and next week, so this all may happen rather quickly without too much in the way of in-progress updates. The interesting bit will be uprating the rest of the car to cope with its new found torques I suppose.

Apologies that there's a lot of "maybe I'll do this" and not a lot of "I did this"!

If you still have a way to connect to the ECU via OBD, could you use an MPPS cable to remap the ECU and get the immobiliser/EGR deleted by these guys? https://www.hdi-tuning.co.uk/ecu-remapping/how-it-works.html it's £100, but the stage 2 remap at 155bhp would be amusing. I used them for my 307 and was very happy with the service.

Edit: sorry, I see this has already been suggested. As you were, good luck with the build!

I have got a 120 remapped ECU if the numbers fit - already tuned by HDI tuning.  Sure we could do a deal on it.

 

It's got the egr and imboliser delete already done.

That'd be absolutely perfect, I have the existing ECU on my kitchen table right now so can check numbers when I finish work today!

Alas it seems my ECU is completely different, I spent an embarrassing amount of time trying to make out numbers on it before realising the connector is different!

I suppose I'll have to get in contact with HDI Tuning soon and see what they can do for me.

I have the cables, though it doesn't solve the immobilizer issue since it seems to require flashing an eprom, which I have the kit to do but not the knowledge.

What do I do with the AC compressor and condenser? Obviously it's not being retained, and it's completely removed from the engine, Haynes keeps telling me to under no circumstances ever disconnect the refrigerant lines. Realistically though is there likely to be any refrigerant left after 16 years? It'd be handy to have it out of the way of swinging the engine out.

My intention today once the engine was out was to set about readying the 205 to pull the xud out, alas the rain went from occasional spatters to all out monsoon not long after Keith left.

This is how we leave the project for the day. I'm off inside to have a coffee and dry off my tools.

Some slightly scary progress...

Easy does it...

Success!

SPANNER IN THE WORKS

20190604_192304.thumb.jpg.1eeca9b1401f94c459dcb7ea8147495c.jpg

Rudimentary measuring showed that the mounting holes for the alloy mount from the XUD existed on the HDi block. Actually trying to fit it showed this is in fact not the case. The cast iron mount from the 307 is obviously completely wrong. I'm reliably informed that a 306 HDi bottom mount should fit, there were only two on eBay and both were in foreignland. Both slightly more expensive than I'd really like, but the one I bought is brand new and seemingly coming from a legit parts supplier rather than a bloke in his shed.

On the plus side, the gearbox went onto the HDi absolutely no problem, there was even a hole in the bellhousing for the flywheel sensor! It'll be coming off again today so we can put the engine on a stand to do the timing belt.

Keith goes home to Orkney for summer very soon, so I lose a convenient extra pair of hands which is slightly annoying. That means that the plan is to fit the engine without the lower mount for now. Engine and box came out as one, but it was oh so tight, so we'll be lifting them in separately this time as some of the angles involved coming out will be impossible going in. That's the plan for this evening.

I think this weekend will see it at the stage that all that's left to make it drive is fit the mount and shafts! Of course making it roadworthy will involve piping the exhaust gases away from the engine bay, but that should be easy.

 

Also, this happened:

This 3t jack makes being lazy so much easier. I do have to wonder what the insurance engineer that came to look at the Volvo that day thought of the various automotive madness going on in the yard.

Looking at the completely bare engine bay in my pride and joy definitely induced a little bit of panic because I know about my tendency to put things off and I'd rather it didn't become one of those projects that never turns a wheel again. Double panic when the extent of the mounts not fitting was realised. Fortunately I'm hung up on the desire to have something genuinely quick that I built with my own two hands, so it WILL be done as soon as reasonable!

Some good money news came immediately after I posted too, so with some careful budgeting I can do a couple of extra things I was planning on delaying a while.

 

With that in mind, what colour should I paint the brake calipers? They'll be under the 307 wheels (on lower profile tyres so they clear everything, that's all worked out) and since they're from the 307 will fill the wheels. I'm torn between blue, red or black, possibly silver for that OEM look. I'm also torn between white and primer grey for the wheels.

Test fit the wheels first - from memory, 307 wheels share the same offset as 206's which is wrong for a 205 and will sit too far inwards, fouling the rear trailing arm on the back and possibly the strut on the front.

Leave any kind of distraction like painting. Just concentrate on the swap.

 

You’ll be cleaning the fridge next...

Yes, they need brought out a little bit so I need spacers, something I'm not completely happy with but needs must unfortunately as funds won't stretch to bigger wheels to clear the front brakes.

I won't be painting the brakes till they're going on, and the wheels will be getting farmed out to a powdercoater hopefully. Again, after the engine is in and on its way to running.

 

Funnily enough, I did actually clean the fridge on Thursday morning because flat inspection!

By the time the belt kit arrived today the weather was a little bit too grim to really bother doing much, especially since I'll be on my own. Don't have long enough bolts to get the engine on the stand so I'll be doing the belt with it hanging from the crane with axle stands to steady it. It can wait till the morning.

      So I bought this omega in 2015/16 with the intention of doing a banger rally to Benidorm. The engine had a horrible grinding noise and the auto box was lazy. I spent £100 buying it, £50 on oil and filter for the gearbox and sold it for £200. I sold it to a distant mate who put another 2.5 Diesel engine in and put it back on the road. He’s been using it as a daily ever since. He bought a later omega in better condition with the same engine and offered me this one back or scrap it. £50 exchanged palms and the Omega is now back on my driveway. Epic. 
      So the plan is this. I’m going to let it sit on my drive for a while, as next year I’m going to do another Banger rally. Cool. Then on return, the engine and Auto gearbox will be transplanted into my diesel Carlton. I hate having a manual gearbox so a diesel auto carlton is a great idea. Whether it happens or not is another thing. But I’ll cross that bridge when I get to it.

      Now in my mucky hands is this S Type Mondeo Lincoln. It's not like a Mondeo Lincoln  though, just uses some of the bits as it's from a time when jaguar was experiencing some 'technical' issues. 
      It has managed to hang onto the feel of a premium car but for the use of cost saving interior plastics made from the same gear that land Rover used in the discovery 2 of the same era, I know, I have one of those too! That has some BMW switches in it though.
       
      This jaag was cheap. Why did I buy it? All I wanted really was a small convertible for the summer to smoke around in, this is the polar opposite. 
      The price was good but these cars are without their expensive issues. I liked the body. It's virtually rust free, a freak of nature and it had a set of premium tyres on it which suggested it's had some money chucked at it.
       
      That's all I wanted really from it. The bolt on stuff and mechanicals are fairly easy to sort out, plus I can upgrade as I feel fit.
       
      Today I've been bonding with this machine. It's got to beat the 3 series I have as a good daily or it's out. It's going to be a tall order, the 318 is bionic!
       
      I have many miles to do in the next few months, I need a motorway cruiser auto. The odd jaunt for a few hundred miles is the 318's and my clutch legs limit!
       
      Now, this car has been owned previously by a few members on here, the work it requires is because it is a cheap car and 20 years old and has a jaguar badge on it. There are a few issues with it.
       
      As said, it has to be put into immediate service. I've owned it 2 days and it's already done over 300 miles, and will do all that again tomorrow! So let's get started!
       
      After about 100 miles yesterday, I reversed it for the first time in my ownership and when braking the noise was alarming! Had a look and the outer rear brake pad was metal on the disc. I only had another 60 miles to go!
      A phone call on the move saw a set in stock back home to be picked up. Sweet.
       
      That was yesterday, I've got a day now to change the rear pads and sort out the dropped headlamps with a couple of screws... A couple of hours it'll be Sorted... He says...
       
      WIND BACK CALIPERS! Yes, they are. My special tool? Sorry? What? No tool?
      Well, I cobbled together a bar and a pair of molies but Christ, that was messing about! I wanted to secure the caliper to the mounting to hold it still but the sliders internal thread was cross threaded on both sliders, so I had to tap them out first. It worked but not without a fight. Then my neighbour came over to have a nose at the new aquisition... Him: Morning, how you getting on"?, Me: "Shit, you haven't got a brake caliper tool have you"? Him: "Yeah, I'll go get it". 
       
      LIFESAVER!!!
       

       
      Sticky slider syndrome ^
       

       
      Fully padded up ^
       
      I took a look around under there, it's nearly all shot. Most ball joints are exposed to the elements so all need replacing but not before a decent jet wash.
       

       

       
      There's little play in the joints so all that goes on the list of parts and graft! Wheels on, I loosened and torqued all the wheel nuts around the car and done the Tyre pressures, we were running soft all round.
       
      Next was the front lights. A screw mod can be done but I took the back off the units and they were, well toast. Nothing much holding the inner lenses still at all. There was only one thing for it...
       

       
      I had readied myself for this. I got hold of a replacement lamp mounting kit with all parts made from nylon. This involved dissecting the lamp which was tough! The mounts that came out, or what was left of them were weaker than Jacobs crackers and just crumbled. To get the bumper off, the plastic under tray bolts were all seized so I had to grind them off. More knackered parts were seen. The auto box cooler has shed most of it's cooling fins, the radiator is sweating and the power steering is hemorrhaging fluid on full lock. There's also a coolant leak at the thermostat housing and there's a high pitch whine at 1000 RPM which turns out to be the alternator. More for the list.
      Still, back to the lights. I need to be able to see tonight so I took a level off the tourings lights and marked on to a wheely bin, these are pretty spot on. Then I can use the bin for the Jaags lights and I won't be far off 
       

       
      Going back together nicely it was a good time to run some tcut over the faded lenses. They need a more intense compound and a machine but will do for now.
       

       
      Looks smart yo!
       
      Then it got dark...
       

       
      I then drove 120 miles in it and drove it like it was stolen. It had it, all of it! Slight brake judder at 90 and I couldn't get the alignment done as I had no time (see above pics)
       
      So now we have to price up priorities like the knackered joints on the rear and a full service, two Goodyears and investigate the power steering leak which, I'll hazard a guess at the rack seals are fubard. 
       
      So in summary, I got a bargain barge that has it's fair share of issues, the interior quality is a bit shocking in places but when the hammer is down, none of this matters! It fits in, it can be a proper giffer cruiser with radio two on at 30mph but it'll turn into a bruiser with some oldskool hardcore at a tonne. It's come to a good home.

      I thought I'd start a thread for this as I'll probably end up asking all sorts of questions, given that this is my first 'proper' Citroën.
       
      So... the ground clearance lever won't go all the way to the highest setting (all others work), which is bad 'cos the book says I need it to do that in order to check the LHM level. It feels like something's seized, so I don't want to force it. Any ideas for a plan of attack would be much appreciated.
       
      Next up are the wheels. I now have a set of 205 pepperpots that have just gone off for powder coating & I need to get some tyres for them. The handbook says the car should have 165/70R14s on, the wheels came with 185/65R14 on. Any thoughts about what size I should get please? Cheers.
