I have scoured the forum looking for information on my Beetle that I just got. I got it pretty cheap because there was some problems with it.
I am getting 5 codes. All codes were there before I bought the car.
1. P0510
2. P0117
3. P0121
4. P0341
5. P1544
I am currently working on the p0341 code.
Since I bought it I have replaced the timing belt, water pump, and tensioner and verified that all the timing marks line up perfectly. So I start doing voltage checks and when testing wires 1 and 3 on the cam sensor connector I am only getting 1.98v.
I am unable to find any further diagnosis on this problem. If anyone has any info that can help me it would be greatly appreciated.
Code P0510,P0121 and P1544 are related to the throttle body. Find someone in your area with a VAG com and have them do a Throttle body adaption on it. That should take care of it.
Is there a wiring diagram for the cam circuit somewhere? With me getting only 1.98v to the cam sensor I am thinking that it is either bad wiring or bad ecm. I am not sure which pin on the ecm connector to test for high resistance.
As far as the vagcom I am looking for someone that has one but am so far unsuccessful. If anyone here is in SALT LAKE and has one that would be awesome.
I REALLY HOPE THAT IT IS NOT A BAD ECU!!!!!!!!!!!!!
You could call Utah Imports. They specialize in VW's and I know they can do a throttle body adaptation for you. Not syre how much it would be, but they are great people and easy to work with.
Did you find out what the issue was? I have the same codes and suspect the battery ground wire that runs under the battery to the transmission ground. Please post solution if you found one. And thank you in advance.
