I thought that real oem would have black or dark brown pads and black electrical selinoid.

Andriy

Did you buy OEM or aftermarket?


Andriy

You definitely need new chain, and CCT.


Andriy

Then how come your pad looks so bad after 20k miles, the one you took a picture of. What side is it, and top or bottom.

Mike show me which pipe on the way, I managed to remove egr. Sorry no more photos with me at work.
What do you mean CCT part # is newer?



Andriy

Everything you need in this set http://www.blauparts.com/proddetail.asp?prod=GF21011-1G
Me personally, I would change just pads (already in set).
To change chain both cams need to be removed.

Looks like CCT was original.





Andriy

I still think timing is your problem (phase position to far from 0 in oposit direction).




Andriy

Mike, when you start your car in the morning do you hear rattle from engine for few seconds, before engine pull?




Andriy

OEM for $15. Pick from salvage yard from 2002 A6 4.2 with low mileage. I know part# same for C5 A6, A8, VW 4.2

Which one you use?

My car is fixed, problem was CCT piston stock, misfire was strange, not same in all cylinders (most in 5, less in 6, some in 7, and few in 8) with different CCT no more misfire. Learn hard way with...

In my case was bank 2, cylinder 5 and 6 less in 7, sometimes in 8. My phase position bank 2 was -15.
I did a lot of research and phase position bank 1 and 2 should be in range +/-6 from 0 group 93,...

Yes, you can have misfire like that with bad cam alignment, that what I had when cam tensioner stop working.
