My name is Robt100, and I have an addiction to Autoshite purchases....Fully Charged!! 27/03/26

[robt100]

1) all hoses replaced and no coolant loss
2) no smoke detector, but given the amount of stuff ive moved about to do the bonnet cable, possibly
3) yep, knock sensor is same work as valley hose, not wanting to touch that!

I have a smoke tester so if you want to come round one day we can take a look.

[robt100]

Thanks @DirtyDaily, I would take you up on the offer, but given how the car was resisting accelerating on the slightest slope today, im not sure it'll cope with the woodhead pass😬

[robt100]

Can confirm I've been a bit of a tit myself....

Sat here and suddenly thought I dont remember plugging the PCV pipe back into the intake pipe, so just popped out for a midnight reconnaissance. Yep, I'd forgotten to put it on! It was stuck under the intake pipe, so prized it out and secured it, will try again in the morning to see if the codes go.

If they do I have two final jobs:

Fix the glovebox soft closing.
Sort out whatever has failed on the rear parking sensors - I just get a long beep when I select reverse atm and thats it, which indicates a fault.

[robt100]

Right, Think I've fixed the problem, going for a longer run this afternoon to confirm.

in the meantime, have some photos of the good condition* bonnet release cable I removed, and of the tiny hole I had to get into to cut with a hacksaw to get the sidelight out!

 

 

You can just about see the hacksaw marks on that top sidelight holder, it was not fun!

[robt100]

As you may have seen from the collection thread, there is a new car in the Robt100 household...

 

we now have the ex @Jazoli and @Dan_ZTT Chevrolet Volt. 

After going to view a few weeks back and agreeing the purchase, Dan took it for an MOT. At this point the car realised it was being sold and threw a hissy fit! MOT failed on unobtanium/expensive mirror indicators, engine light on, and the dreaded "service high voltage charge system" error. But with the car suiting our needs to a tee, we went ahead and it'll be a short project whilst the BMW is still about. So picked it up yesterday and here it is at the tyre place getting 2 new fronts (also MOT faliures) before the 120mile trip home (hooray for range extenders!). 

Went to collect the car from the tyre place after going to lunch, and the guy says "ive got good news and bad news", just what you want to hear when picking up a car. "tyres are on ok, but the stud on the O/S hub snapped off trying to remove the locking nut" 🤐 another job for the list! It managed the journey home on 4 bolts ok, so there is that.

And here it is with the 3 other AS bought cars (5 from here so far I think).


This mornings job, give it a clean. Having been a family car, and sat for a while since being replaced with the new one, the car has grown a little bit of an ecosystem on the outside. So gave it a brief clean up this morning.

Rinse down with the hosepipe, a brush with the WFP window cleaning gear, and then onto iron fallout remover....

looks like it needed that!

And a quick rinse over and towel dry....



Much better! Still needs a proper decontamination, polish and sealant, but this'll do till it passes the MOT.

[robt100]

First job on the list, try and scan the codes using the volt app. @castros_bro very kindly sent over a spare bluetooth OB2 reader dongle dooberry thing for me to use. Plugged in, after a bit of fumbling about with the phone (I hate phone style operating systems and touchscreens, but managed not to swear and scream at it too much) I got the reader connected. Sadly it didn't work, apparently the volt needs a - insert a 7 character hexidecimal protocol here - connection to be fully functional. I'm sure it'll come in handy for the other cars, but looks like im going shopping for a fancy ob2 reader, might see what the guy who made the app uses and go from there.
I also tried to check inside the charging port for water ingress, only problem is, it seems to be stuck 😅. @Dan_ZTT you're gonna have to tell me the knack to getting it open, I can hear the motor/solenoid move to unlock, but the flap stays firmly stuck down?

So, day 1 - not so sucessful.

But, I did find a guy locally on the EV forum who has a full SKF front hub kit including all the single-use bolts who wants just £45 for it as he no longer has the car, so thats a bonus!

This car has two OBD2 ports, try the other one 😛

Argh. That flap is usually fine but has occasionally had bad days in the past, in which case a fingernail or credit card or similar under the edge at the same time as you push the button on the remote, it will pop right open

Thats....odd lol. Wonder if thats why it looked a bit lacking in pins....

yeah there is definitely two, one to the left of the centre console and the other if I remember correctly is by the passenger door.

it really pissed me off because none of my diag tools would work, until I found the second port.

[robt100]

Yeah, I have done a bit of research since you mentioned it, and its something to do with wiring the obd2 different, so one works for High Voltage/drivetrain stuff, but on the normal OBD (whichever one that is) it all goes to the chassis pin instead which confuses it. I guess the passenger door one is the original US drivers side, just to really confuse things😅

My Delphi worked on it fine although it thought it was an Ampera and there wasn’t a lot you could do tbh.

I may have found an app quite similar to "Mygreenvolt" that can do rather a lot, just need to get the OBD2 dongle working 😬

Question for other current/previous X350 XJR owners, or 4.2 supercharged jags for that matter i guess (looking at you @DirtyDaily@NorthernMonkey@MVX11V and co).....

Do you find the supercharger louder than the engine/exhaust? Gave mine a blip under a bridge/tunnel the other day, couldn't hear the engine at all with the windows down just the scream of the SC. Also gave it a blip in neutral another time and it was all supercharger noise. Not that I wan't the drone of a loud exhaust all the time, the quietness whilst cruising etc is nice. But it goes feel like when I put my foot down it sounds more like a henry hoover with something stuck in the end of the pipe rather than a performance V8. Just wondered if you guys had the same experience?

Belt a bit tight maybe? 

Not the WORST sound in the world mind 🤭🤭🤭

[DirtyDaily]

The one i had as a daily had a fairly aggressive pulley and that supercharger howled, in a good way. I loved it, it was comical how loud it was and it definitely dominated the sound track, the exhuast i found really quite muted.

[Bear]

The Deranged Rover sounded like all hell had broken loose when floored. Nearly all supercharger with a hint of transmission doing the gear equivalent of red-face-bulging-neck. And you didn't get to hear it long before a corner or speed limit or physics decided to intervene.

[robt100]

Thanks both, sounds like its normal then! And yep @Bear 0-3points takes about 5.5 seconds🤐

are ya doing it right

 

[MVX11V]

Smoll pully and modded intake screams like a banshee stubbing its toe on a misplaced aztec death whistle. It's at the point where the engineering part of ones brain tries to make sense of something being that loud, and not exploding.

Totally normal.

Sounds like an accurate description 😅 its louder than the local air-raid sirens for the hospital (yep, one of those fun ones!). I think it is then just a case that the supercharger is extra loud rather than the exhaust being muted.

Hows the jag been running?

Not bad, think I've got a coil pack on the way out. As it goes really lumpy as the idle drops off the warm-up rpm to the standard 500-700rpm and kicks the restricted performance on. But the EML code is very helpfully coming up as "N/A" 😅 Delete it and it wont come back again till you turn it off. Got a bit of a clunk on the front which I think might be a subframe bush, and the pedal is long due to all the fluid dropping out when the rear brake pipe failed, so I think there is air in the ABS pump, still drives fine though bar a few funny noises I need to trace bt arent 'im about to die' sounding. Managing 23mpg on normal driving and 29+ on a run. And the 10% pulley certainly makes a bit of difference!

[MVX11V]

Mpg is spot on. Did you change the sc belt for another type (shorter). I'm tackling belts soon and need a shorter sc belt, also loosing ac compressor so need to measure after that!

I think we used an original, but new. I'm still on the one-sided belt as its an early 2003 model. Doesn't seem to be causing any problems and no unwanted noises, as far as I have read a normal belt would work fine for even the 10% upper pulley. Without the AC you might need to measure up with string for length and see whats out there.

[robt100]

So a little progress made on the Volt this last week. First off, using a new OBD2 bluetooth dongle thingy, and an app from a very smart Ukrainian man, I have managed to reset/delete the "Service high voltage charge" warning from the dash. How long it will hold I don't know, we will see once I get the car MOT'd.

Next up, had a go at getting the indicator bodged/fixed temporarily to pass an MOT. Taking all the wing mirror apart to get to it was simple enough, then the fun started. The indicator unit is a 3-piece part, the backing plate, the centre LED holder, and the clear cover over the top. Good news is the LED plate is held in by 2 screws so can be easily disconnected (apart from having to cut the plug off the end!) from the rest of the unit. The bad news is, its stuck behind the clear cover on the top which has been glued in with the strongest substance known to man so you cant actually remove it 🙄. So, time to get a bit angry with a grinder, screwdriver and pokey stick!







And its free! 

Now, why was only one LED working on the indicator (Apart from the copper in the plug being tarnished as anything)




Yep, I reckon that'd be the problem!

New LED strip fitted, though sadly the sticky-backing on the strip doesn't stick, so may need to get it apart and hot glue it at some point. But all back together and the wires posted through the two holes in the back ready for soldering to the plug.




Put it back in the wing mirror and time to give it a test.......



Looks pretty good to me, and my wonderful new sellotape clear cover makes it look better than the still damaged passenger side indicator. Just missing lighting the bottom part of the indicator easily as the LEDs have come away from the backing where they were originally stuck.

Next job, book it in to get the Hub replaced, and get an MOT on it 😬

Calling all XJR boffins......

Decided on the off chance today to stick the new bluetooth OBD2 thingy on the Jag to see if it gets anything other than "N/A" as the error.
And it does!

P0171 Bank 1 too lean code.
Now, this side is the one that needed wiring repaired by @DirtyDaily and a large gap between downpipe and manifold sorted by @Jikovron, and I fitted a new genuine Denso Lambda sensor. So it SHOULD be fine. But looking at live data, the lamdba sits at 0.9v constantly (apart from the odd blip to 0.91v), sitting it at +25% short term fuel trim. Whereas Bank 2 all the readings seem to work fine and it moves between about -4% and +5% short term trim. Could it be a duff sensor? Too late to return now I think, which is a bit of a pain. Just wondered if anyone might have any ideas? Does sound a bit 'ticky' on that side so I wonder if there is another blow somewhere, but id still expect a little difference in readings depending on load etc.

I suppose an easy check for the sensor would be to switch them. If the problem follows sensor, if not its something on that bank. Potentially wiring issue?

If not a wiring issue i suppose the only answer would be to do a smoke test, intake and exhuast to see if its escaping. I have a smoke machine if you would like to hook it up.
