Car D.I.Y.

Are you fitting OEM sensors (lambda) ? I hear aftermarket ones can sometimes not work well at all on some cars, ditto the cat .
MAP sensor ? (assuming one is fitted)
Throttle body clean ? Buildup around the butterfly can cause issues with mixtures being thrown off.

I hope this fixes the problem. The RR session will be helpful too. If you've not witnessed one before, it can be a bit intimidating, especially if its your car

Fitting the better quality Cat appears to have fixed the problem, CO levels came down from 0.7 region to the 0.07 area, although the tuners suggestion is to replace the new Bocsh Lambda with a Denso/Nippon one, he believes the Japanese ones work better with Japanese cars.

Oh & it made a huge 110bhp

Yebbut, 110 bhp pushing something the weight of a carrier bag is probably good going ( but I suspect you know that already )

Moral of the cat story is pattern parts are rarely a good idea.

In my brief career as a Saturday boy mechanic, we came across several examples.

We now have an issue with the LT35, it went to Santa Pod with the drift car on the back, no issue on the way down, come to try to come home & it wouldn't start. Would fire & run for 1-2 seconds, then stop, it did the same when I once tried to start it with the wrong key. We think it's the immobiliser not coming off, we got it recovered home, which was fun when the recovery guy turned up & saw the BMW on the back of it.

Went out yesterday & the fing started up first throw of the switch but on turning off it now won't start again, looks like we need to find somebody with Vagcom or VDCS (or some such acronym) going to pull hte ECU this afternoon as they appear prone to water damage, hopefully that's all it is.

Charged the LT35 battery up overnight, put it on this afternoon & it fired up, so moved it off the road where it's been for the last 36 hours, much to our neighbours annoyance. Got it onto the drive then turned it off, it started up 6 more times without any issue, but still decided to look for the fault.

Went for the ECU to find













Started to gently try to clean up the ECU but came across at least 1 broken pin



Anybody know a good company that is likely to be able to repair it?

Seem to be well thought of on one of the Volvo forums I frequent, not used myself.

Looks like it's the only broken pin, so we're wondering now if we can just wire around it, solder a wire on the inside drill a hole in the case & connect back to the wire in the harness.

Watched video where the guy used vinegar to clean off the verdigris anybody any other thoughts?

I like the theory although making it absolutely moisture proof might be hard (if I'm interpreting your description correctly)
I had a miniature output relay go once in a small control unit in a machine. No spare available but I found a bigger relay, soldered link wires from the PCB to the new relay and sat it in a space in the unit. Worked perfectly. It sometimes pays to think outside the box.

Had a proper look today there are 3 broken pins fortunately 2 aren't used but 1 is so for now this is the solution

I'm wondering if any of you have any ideas on a good OBD2 reader. We have decided not to be fleeced by the main dealer To have an oil change when it doesn't need it . Most of the service is what a garage does for an MOT so no point in paying twice .
I have a Jaguar XE 20t with the Ford Ecoboost engine .
Thanks .

There are quite a few. My son's ODB2 reader does most of the VAG stuff. Mine is a bit more generic but it can clear codes. I've got a bluetooth one that runs Torque app on my phone. Someone could recommend a good JRL unit.

After my son fried his ECU by trying to flash it (and lost power) - no idea why he was doing this.... he picked up a new ECU for £200 but it wasn't coded to the car, so wouldn't work, plus all the component's threw errors as they weren't coded to it.

VAG wanted £1200 plus to do it. He contacted a specialist about 12 miles away - £86. AA towed him out there and car was fixed within a couple of hours. Jus thope he learns... I doubt it as...

He has a turbo off a 1.4 TSI to go into his 1.2 110 bhp. He's also bought a custom exhaust, and additional 'pipes' and plans getting it re-mapped to 180 bhp.

I've suggested he get's a specialist to fit the turbo... I doubt he will listen - it's a straight swap.

I'd suggest getting one that is a Bluetooth link to the phone, rather than a WiFi link. They seem to be more stable. Key is making sure the App does what is needed and is compatible with the phone and the car.

TBH if you can do an oil change yourself, it is well worthwhile for a cost saving, but not doing oil changes can be false economy. With modern emissions controls oils take a hammering, especially with diesels, and the extended service intervals have thrown up all sorts of issues which could have been avoided by simple oil changes, particularly where cars do lots of short runs.

TBH I'd be happy doing the mechanical swaps, but I'd be taking it to a professional to be doing the mapping

Just to add I'll be Supercharging my kitcar once registered, I know which tuner/rolling road specialist I'm going to, I'll be buying the ECU he recommends.
