Hi frosty I had exactly the same problem and couldn't work out what was going on . Mk3 vr6 1996 obd2 aaa . Drove to the shops engine up to warm . Got the shopping and when I restarted the engine it would rev then just die. It would restart and then be fine !! I checked and replaced the crank sensor and maf still same problem . Thought I'd take the throttle body off and clean it . I removed the air intake pipe to the throttle body and noticed a very small spilt on the underside in between the concertina . The underside gets hot from the exhaust manifold and the heat was causing the split to ope

Got a forge 007p diverter valve hopefully do the trick

Yes vag one preset. Thats why i went for it, plus no piston to get shitted up. 22mm rings a bell but it could be 25 so i may be wrong. I'll try and have look later mate

A bit late now i'm afraid @noggin the article has been completed with the input @scholsey

I used a genuine vw one(bosch) from the 1.8t engine or buy a forge one if you want bling lol

Vince did me a "safe map" before I went down there so I could at least drive it without worrying, it was still running quite rich mind as the plugs were sooted up quite badly but I had been driving it around for a few weeks before going for a map.

Hmm. Normally when no engine speed recorded on diagnostic tool, that's gonna be due to the crank sensor, that's directly where engine speed signal is measured. It's 100% gonna be a Sensor. If you got a spare, try camshaft sensor too, it surely has to be one of those two

It recircs air back through charger when throttle is closed mate

We had a 'guess gaz's horsepower game' at work before it went for mapping!! Lol You will need to run it hard after, as they dont make 6psi till about 6000-6500rpm!!

Well wont be getting continuity through that terminal its the earth for sensor side not for heater side.hopefully found the problem
