Carrera 2 2000; replacement of idle purge valve


Recommended Posts

I purchased a new idle purge valve, the one located just above the alternator, p/n 996 110 129 53, and I plan on installing it this coming week-end.

Could somebody advise how to release the electrical connector? Usually there is a little tab to press to unlock the connector, but I could not see any tab.

Thanks

This is a sore subject for me. When I removed my engine recently getting the plugs undone without damaging the plastic clips was the hardest part of the operation. Each plug seemed to have a different release, and like Ahsai says, the releases are hidden about half the time so you better be into "braille". Porsche didn't make it easy... Sorry, I had to get that off my chest...

Martin,

The symptoms are: tapping noise coming from the valve and idle RPM oscillating (+/-) 50-75 rpm. Both occur when the engine is warm. Two or three times it looked like the engine was going to quit, but eventually it didn't. Right now I also have the engine light on (Error P410). I have not yet replaced the idle purge valve, so I don't know if the problem is cause by this valve. I can post a message after Ido it.

Thank you Philip for the reply & update!

Is idle purge valve also referred to as idle control valve for 00 C2s?

Martin

Martin,

My understanding is that the 00 C2s, equipped with electronic throttle, do not have idle control valves.

The idle purge valve is another valve. It is located above alternator. Do a search for part 996 110 129 53 on the Pelican Parts website to see a picture of this valve.

Have you cleaned the throttle body well - both in front and behind the butterfly?

I have cleaned the throttle body well in front of the butterfly. In the back of the butterfly I did what I could. I believe that to clean it real well behind the butterfly it necessary to remove the throttle body from the engine. Is there a procedure on this forum on how to do it?

Thanks

After some additional cleaning of the throttle body behind the butterfly, in the areas that are difficult to reach, the idle is now fairly stable.

Thanks, Loren.
