swiftkid 1 Posted June 5, 2015 Yea everything is wired up as it should, even those annoying bits like evap canister are wired up. I'm hoping it was only because the engine had been sat for about 2/3 years without running properly, plus the car has been sat for a year and a half. Other than that, compared to my daily bmw 320d, it bloody shifted! Just power right the way through, definitely need big big brakes though! Quote Share this post Link to post Share on other sites
swiftkid 1 Posted June 7, 2015 Well took it for a proper thrashing on the way to test centre and it's made little to no difference so it's back to the drawing board. Running 2 front lambdas without rears, they have not been deleted yet but are unplugged, sports cat and full miltek, I'm thinking it's fueling related rather than just cat related as I never had any problems with the vr engine. Either way, it's just another kick in the nuts and I'm seriously starting to lose the love. Quote Share this post Link to post Share on other sites
Mk3highline 10 Posted June 7, 2015 At a guess you might not have closed loop fuelling/long term fuel trims? With the rear lambdas unplugged and not coded out Have you got vagcom/scanner that will normally show if it's adjusting the fuel trims Quote Share this post Link to post Share on other sites
borachris 0 Posted June 7, 2015 Did it fail on all emissions? HC, CO2 and CO? Did they test the emissions as soon as you got to the garage or did it have time to cool down? Ideally you want the cat red hot and test it straight away. Quote Share this post Link to post Share on other sites

swiftkid 1 Posted June 7, 2015 Thrashed it around on way there and tested it straight away, made little difference. Quote Share this post Link to post Share on other sites
Sean_Jaymo 0 Posted June 7, 2015 (edited) Have you plugged it into vcds? Mine ran fairly poorly before I had the rear lambda bungs fitted but still went through the emissions OK. The lambdas were actually fitted on mine though, just hanging secure in the bay so in effect they were seeing fresh air and not missing entirely. So much better with the rears in but I'm umming over whether a vince map without the rear sensors would be good or not for me.

KipVR 1 Posted June 8, 2015 You need the rear sensors in. I had exactly the same problem before I fitted mine. Quote Share this post Link to post Share on other sites
KipVR 1 Posted June 8, 2015 Even if they are plugged in but not in the exhaust. Quote Share this post Link to post Share on other sites
swiftkid 1 Posted June 8, 2015 Seems weird that they just have to be plugged in to lower emissions, especially HC. Everything I've read says they are there just to make sure the CAT is working but I'm not going to question an easy fix! Do you know which measuring blocks I'd be wanting to look at to make sure this sorts it? Quote Share this post Link to post Share on other sites
Mk3highline 10 Posted June 8, 2015 Think you will find that with some fault codes the ecu stops adaptation/adjusting fuel trims I have same problem with having an egr and sai faults Hopefully vince will fix them in couple of weeks Quote Share this post Link to post Share on other sites
coullstar 0 Posted June 8, 2015 Same issues when I had on my 24v Corrado. They need deleted properly. Quote Share this post Link to post Share on other sites
swiftkid 1 Posted June 8, 2015 Well this thing is starting to really get on my nerves, it absolutely stinks of fuel... I could pretty much catch the fuel out the exhaust and just throw it back into the fuel tank. Couple of things I really really didn't want to see... correct me if I'm wrong but that looks like chain stretch? And appears to be staying in open loop, connected up the rear lambdas and tucked them away, reset error codes let it idle up to temp and no lambda adaption. VAGCOM logs and error codes below, strangely enough I do have the SAI relay wired up. If this sodding thing doesn't start behaving and giving me some luck it will be for sale!

Mk3highline 10 Posted June 8, 2015 Omg Hopefully it's something not too serious Could it be a bad earth? What's been done to the ecu? Just the immobiliser delete? Quote Share this post Link to post Share on other sites
borachris 0 Posted June 8, 2015 A high HC fail is usually because of inefficient combustion isn't it? Low compression, worn valves, poor timing, worn plugs/leads etc I'd be concerned about the reading in block 209 regarding the chains, which could cause a timing issue to cause the high HC? Quote Share this post Link to post Share on other sites
Sean_Jaymo 0 Posted June 8, 2015 Who did your immobiliser defeat? Quote Share this post Link to post Share on other sites
swiftkid 1 Posted June 8, 2015 Yea, as far as I'm aware it is inefficient combustion but I don't think its as bad as low compression etc. It does seem to point towards overfueling. Vince did the immobiliser defeat so I'm more than confident with that being right Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted June 9, 2015 (edited) What Vince normally does is defeat the immobiliser so that you can drive it to him for a proper map, and delete all those codes. I think because the ECU thinks so much has failed, it doesn't know what the heck is going on and is running a rich safe map. What engine is it? Blocks 209 & 208 should read in KW (german for degrees). Not sure what 'CF' is. Not seen that before. If block 209 really is at -9, it's either not timed properly or has chain stretch.

swiftkid 1 Posted June 9, 2015 Its an Audi A3 3.2, fairly sure its exactly the same as what you had Kev. I'm a bit stuck with what to do, what triggers closed loop, is it just blue temp sensor (R32's version). The ECU does seem to read water temp, I'm going to try run it up to temperature again tonight but it does seem like the lambdas are just not showing any values in the ECU at all, MAF readings seem about right (compared with what I've seen on forums) Quote Share this post Link to post Share on other sites
mic_VR 3 Posted June 9, 2015 Not sure it'll help but my 24v wasn't reading any lambda values due to other faults within the ECU (MAF, SAI etc). As soon as I got those faults cleared (by Vince) the lambdas began reading and adapting correctly. To me it looks like you need to solve some of those fault codes first mate Quote Share this post Link to post Share on other sites
Mk3highline 10 Posted June 9, 2015 Agreed with above Quote Share this post Link to post Share on other sites
sexybourbon 0 Posted June 9, 2015 Can you not book it in for mot at stealth so you can simply drive it down there to them ? Would save getting it trailord down there for them to work on it ! Sorry its not the input some can gove but thats what id be doing to get it sorted at this point mate !! Plus it will take some of the stress and frustration out of it for you before it drives you mad Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted June 9, 2015 +2. I notice the N80 evap valve isn't connected as well. Without SAI, N80, rear lambdas etc connected or coded out, it won't run properly. When all is well, closed loop will run not long after start-up and you will see some adjustment values in the measuring blocks. Because of all the faults, it's assuming a complete meltdown and is running a very basic map to get you home. Next step is to get it up to Vince. -9 deg is on the ragged edge as -8 is the limit. Yours hasn't thrown the "Cam / crankshaft correlation error" yet, so you're within limits, just. I reckon yours is on the change over year when VW introduced upgraded chain gear, so yours might have the older MK4 stuff. Quote Share this post Link to post Share on other sites
swiftkid 1 Posted June 9, 2015 It sounds like my sort of luck getting stretched chains. Not a chance am I risking driving 3 hours to get my car cubed, I'll try give vince a call tomorrow for advice. It's frustrating I can't do anything, just want to get it through mot then I can properly finish it off Quote Share this post Link to post Share on other sites
mic_VR 3 Posted June 9, 2015 Does anyone else have a similar conversion and can get some screenshots of the same blocks in vcds to give you an idea of how seriously out it might be. Chain stretch has got to be unlikely hasn't it? Given the mileage and setup of the engine. Quote Share this post Link to post Share on other sites
