So I just got this 2000 A6 2.7t Auto for really cheap that had a waterpump failure. I did a full timing belt job used crank pin and cam lock bar to set timing. I am getting codes P1340, P301, P302 & P303 so i checked my timing belt job again it was dead on. I replaced cam sensor and checked wiring to no avail. Now I am checking the cam chain on bank 1 to see if it is on time. Can someone confirm the count on my chain links in the attached pictures. I have read other treads which resulted to switched CCT on both banks I havent done that yet and is on my next to do list if my chains is the right count.

Thanks in advance for your help.

 

Hard to tell if both cams' notches are aligned with the cap arrow mark, & didn't know if pics are bank 1 or bank 2. But I do know this is the correct cam chain setup you should have.

Don't switch chain tensioners btwn bank 1 & 2, as they are not interchangable! But you could check the part numbers to make sure they are on the correct side, if you suspect they got swapped somehow. ECS tuning would list the correct p/n's.

 

Thanks for the reply. The pics are Bank 1 passenger side and the notches perfectly align to the triangle caps. If the notches and caps align perfectly does that mean it's on time?

 

Notches aligned to cap arrows means the cams are timed correctly to each other on that bank. Count the chain rollers to be sure, but having both notches aligned is a good sign. Crank should be aligned to it's timing mark, crank lock pin should be installed/aligned, & #3 piston at TDC compression stroke.

Error could be driven by bad camshaft position sensor. On my car the CPS are the same for bank 1 & 2. But bank 2 CPS was more difficult to remove due to a coolant line. So you could clear codes, swap CPS L-R to R-L, & see if codes & misfires switches to bank 2. If so, replace the bad CPS.
