Off throttle - the car seems to continue to fuel itself

[h100vw]

Listening to ^^^ this guy might be a good idea too. He is a VW tech.

Snail Style - do you know the are in VCDS where you can check the clutch switch operation?

I poke around until I find a row of binary and then dip the clutch and brake pedals. You see the 1s and 0s change.

[Snail Style]

Should be a mvb in the engine module somewhere, or as h100vw said just look for some binary that changes.

Was a common issue back at audi on the 8L A/S3's to have them fail, no fault codes thrown but revs would flare up on shifting. As there was no codes thrown generally technicians just scratch their heads with it.

Just for reference regarding your comments on engine oil temp, here are a few pics i took this morning on a 25 minute commute. All open road so speeds between 70-110kph for 95% of the trip.

I was in a hurry so i wasnt babying the car this morning - temp didnt exceed 95.

My GTI would sit around 95 degrees in general 60km/h driving in average conditions (say 22 degrees). If I was stuck in traffic, driving quickly or the ambient temp was higher, it'd regularly get as high as 102-103. And if I was driving hard on country roads it'd get as high as 110 occasionally - but it would need proper pushing to get that hot.

Between 95-105 degrees the oil cooling is limited apparently (as this is the normal operating range); only above 105 degrees is the oil cooling unrestricted.

Engine oil temps can be affected by many factors, not least of which was the engine run-in technique. An engine that was overly babied may never have bedded in properly and may always run hot and consume some oil.

If it's any consolation, the latest-gen EA888 in the Mk7 (and in my S3) sits at about 107-109 degrees on a cold night when driven gently!

I've attached two screen grabs from VCDS. One where the car behaves as expected, the other where it is obvious there is a delay before fuel stops being delivered to the engine.

Any thoughts?

[elephino]

I had something similar on my Mk5 GTI where the solution was a throttle sensor. Might be different, though, as it appeared more like a "normal" sticking throttle.

I've a thread going on the ross-tech forum. Uwe says that from the data I've captured he can see that the throttle valve closes pretty closely after the throttle pedal.

Have VCDS? Make sure the clutch switch is working correctly.

What made you suggest clutch switch? After months of chasing this the dealer decided to replace the clutch switch and they think its fixed it.

[Snail Style]

Because i am just that good.

Because i am just that good.

Perhaps not good enough? I just got the car back after the dealer had had it, chasing this issue, for 6 weeks.

Issue is still there. Clutch switch didn't work L

Further more, after sitting for six weeks at 2/3 full the fuel guage is now stuck as I filled it wit fresh fuel and it still reads 2/3

Haha can only be so good over the internet and without physically testing it. Might be time to burn the thing

Yea if you were closer I'd let you have a look. My vagcom throws no errors. VW service kit shows no errors so we're in the territory of R&Ring parts and hoping for the best.
