Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

When car's up to running temp it sometimes stalls when engaging reverse gear. Problem seems worse after a run when engines warm. Car runs at a constant 180.

POST 2Original post

180? Is it US spec? Also, what model year? Manual or Tip? If a 98 or 99 it might be the idle control valve, or it may be the MAF. Not sure why it only does it in reverse though.

POST 3 / ORIGINAL POSTEROriginal post

Thanks again Richard, car is 1999 tiptronic, built in Finland, milage is 65,000. It seems like an intermitent fault, but it only stalls when engaging reverse, sometimes revs die right down and it doesnt stall, other times it does stall. Will get those two items checked out thanks again. ps How do you check MAF sensor?

POST 4Original post

I thought from the sound of it that it could be the crank sensor, but the reverse thing seems odd. My crank sensor failed but only when warm would it cut out, it gradually got worse. It took me a while to diagnose as it corresponded with low fuel the first time it happened, and I thought it was a fuelling issue for sometime while I checked out all of those components. Is there some sort of safety feature where the tip won't engage reverse while the car is moving forward? If the CAS / speed sensor is faulty perhaps it thinks the car is still moving? Just a guess.

POST 5Original post

The only way of checking the MAF sensor is by reading the output with a diagnostic tester. Although they are supposed to have a life of 100000 miles, they often start to become problematic at half that figure. I would suggest taking it out and give it a good clean with an isopropyl alcohol spray.

POST 6 / ORIGINAL POSTEROriginal post

Thanks again guys for those tips.
