    Hi guys,

    just wanted to check if anyone has come across this before, bought this 2006 A3 Quattro DSG with a misfiring fault, apparently the previous owners had this problem, got the chains and tensioners changed and gave up. Fault code was incorrectly correlation with cam and crank, when I looked at the measuring blocks I found that the inlet cam timing was 40 degrees out, so stripped it down and not surprised to find the inlet cam was not lining up. When I further investigated the inlet cam could be move an 1/8th or a turn while the chain was still holding the sprocket.


    Taken both the camshaft adjusters off and the inlet one can be moved, yet the exhaust one does have some play but only about 0.5mm

    see pics below of the cam adjusters with the insides turned fully anticlockwise, marked (pic 1) and then turned fully clockwise, you can see that the inlet cam adjuster on the left has CONSIDERABLY more movement (pic 2).

    Has anyone come across this before? Doesn't seem normal to me.....

    If my understanding is correct the cam adjusters should lock in place and when oil is injected this would unlock and vary the timing.

    p.s. strainer for valve adjustment body was clogged and torn.

    thanks in advance.

    Thanks for the comments, believe ice resolved it as the strainer to the valve adjustment body was blocked, going to rebuild the adjustors and put it back together.

    Hi
    I was wondering how you got in with your 3.2 camshaft correlation fault. I have the exact same fault, I have just changed the chains and it's the exact same. I am thinking the camshaft pulley is faulty? But was interested to see how you got on?
    Thanks

    Hello,

    Have you timed the intermediate pulley correctly ? It can be half a tooth out if the crank is one revolution out.

    Thanks for the response. I am happy with my lower chain and marks. The upper chain I have to wiggle the both shafts a ball hair to slide tool in. But on vag com its shows the exhaust cam is 0 degrees and the inlet at 40 degrees. So was concerned there was something else wrong like the pulley or actuator or is it the timing? What fixed your fault ?
    Thank you

    That is very weird that the camshaft tool fits but the phase angle is incorrect. There is another measuring block that tells you the exact angle of the intake and exhaust cam (around field 200ish, check the label file).

    I assume you have also changed the chain guides?

    If the cam pulley was faulty, you would not be able to fit the locking tool, they are a very basic engineering design....

    Probably better for you to give me a ring buddy. (number on my site)
