hello and thank you for contacting just answers
what is the code that you are getting it should be one more digit.
P0012 - "A" Camshaft Position - Timing Over
It is 16. I am sure of that.
What are you talking about? This model has a audi variable valve timing actuator.
I never removed the left cam or the timing belt so the crank and the cam should be in time. I lined up the left cam to the timing mark on the number 1 cap. I used a diagram to check exactly how to count the 16. I ignored the right cap timing mark. I will tear it back down and check to see if the timing is still on target.
I do not know how to test the circuit using the scanner but mine is an Actron so I will look at the book and see if I can figure it out.
I removed the plugs and set the timing mark to TDC.
I removed the right caps in sequence as well as the front cap and the back cap on the left side. I loosened all the other caps on the left side.
I picked up the cam and the solenoid at the same time and slid the actuator out.
I replaced the rear gasket.
I marked the chain on the left side just to the left of the timing mark and counting it inclusively I counted the 16 mark the chain and aligned the right cam timing cut out that point on the chain.
I reassembled the engine and rotate the engine by hand to insure nothing was hitting.
The engine ran fine but then the code came back.
Before or after I never had any problems with the engine running.
I did have to do it twice because before I had the diagram I set it to 15 because of the timing cap on the right side. The engine ran fine but it didn't have enough power.
I checked the time and there is still 16. I checked the bolts to make sure nothing was loose. I cleared the code.
test electrically using a wire diagram and the scantool to check the output settings. Do you know how to do this test?
I used the scan tool but only thing I was able to do is run the ignition scan. At idle I found a spec of between 5 to 15. I graphed the data and it appears to be between 5.9 and 11.
I looked at the frozen data and the event occured while traveling 63 miles per hour. The fuel Banks were -1.6% on both if I am saying that correctly.
I drove the car to work today. So far no codes.
I used an aftermarket part. I am wondering if that might be it.
I noticed a rattle at start up. Can oil pressure on the lifters effect anything? I am at a loss.
