The newer pcv's have an additional check valve in one of the pipes if your car is older you need to change the pipe as well or stick to a certain revision before the check valve was added.

I had this when i replaced a PCV for a later version.

I took it off and got the same part no. as the one fitted and that cured the problem.

I replaced mine with the N version - Part no. 06F 129 101 N a couple of weeks ago and all has been fine, certainly not had any rough idling.  Guess you'll need the new check valve as Fab5freddy says.  :happy2:

If your car is an early one it will need the N revision valve. If your car is circa 2007 then it will need the P revision valve. If your is the later one id say your rear check valve is broken and needs replacing. Or you could just fit the N revision and not bother with the rear breather hose.

Just seen your car reg in the members rides. You need the N revision as yours is a 2006 model.

Is 06F 129 101 L not the right part number?
