Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I hand wash my Porsche every few days, only twice have I used a touchless car wash because I didn't have time for the hand-wash, first time while driving out of the car wash the car choked while driving through the dryer, rpms will fly up to 2000+ then down to few hundred ect, and then chokes itself out and shuts off, 2nd time I went to a touchless few months later I avoided the dryer but the car still choked itself out once before I even got to the dryer and once right outside the car wash, I have to redline it for few seconds and than everything works great.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I hand wash my Porsche every few days, only twice have I used a touchless car wash because I didn't have time for the hand-wash, first time while driving out of the car wash the car choked while driving through the dryer, rpms will fly up to 2000+ then down to few hundred ect, and then chokes itself out and shuts off, 2nd time I went to a touchless few months later I avoided the dryer but the car still choked itself out once before I even got to the dryer and once right outside the car wash, I have to redline it for few seconds and than everything works great. Of course after realizing the first time wasn't a fluke, I never do any kind of wash but hand-wash now is this normal?? I assume it is because of the position of the motor/intake, water/soap/the hot blower get fed right into it, but I just wanted to make sure 1999 Carrera c2 100,000kms(65k miles about) k&n cold air intake thanks

POST 2Original post

There was an article in a recent Panorama that you should not use a car was as it would overwhelm the drainage channels of the 996/997.I'm sure it overwhelmed your airbox or wet the wires coils or wiring in the engine compartment.You could have had hydrolock or worse! Do you have K&N air filter/intake?

POST 3 / ORIGINAL POSTEROriginal post

oh man glad that didn't happen..... its got the k&n cold air intake thanks for the reply

POST 4Original post

Sounds like the high pressure water foiled in intake to me. It takes very little pressure to get water into the engine bay.
