irractic idle after timing chain and belt change

(1/3) > >>

GTI-MATT:
I done a timing belt, cam chain and tensioner change and when i started it up it surges at idle after a couple of seconds of running. I then took the car down the road and it drives perfect but then the mangement light came on. Read the fault code and it came up with P000A/000010 - Camshaft A (Bank 1 Intake): Positioner Slow Response. I am 100% confident the timing is correct so wat else could it be? I read something about some o rings that seals the oil feed in the chain case to the camshaft adjuster. Anybody had this problem just want some ideas before i strip it again monday morning. Cheers

If you haven't already read this http://www.mk5golfgti.co.uk/forum/index.php/topic,106158.0.html

Then check with VCDS what timing values you have for the measuring block quoted in the above post. If your values match what they should be then come back.

Excellent thanks mate

I had a golf come to me with the same problem a few weeks back, turned out the cam timing was out slightly, and 2 of the 3 plastic rings/seals on the cam adjuster were broken from where they had put it back on.

I recommend to always change the rings/seals when doing the timing chain as they seem to go extremely brittle over time. Especially for the sake of the £18 or so that they cost.

Car ran perfectly after having them replaced and the timing adjusted, hope this helps.
