Audi S4 B6 Avant V8 4.2 (P1347 fault) - Timing Chains Replacement / Camshaft Adjusters

This Audi S4 imported from Japan was brought to us with engine light on. Car was misfiring after a while and there was rattle coming from the engine. VCDS showed these fault codes:

P1347 - Camshaft position sensor bank 2 G163 / Engine speed sensor G28 incorrect correlation
P-0300 - multiple misfire
P-0304 - cylinder 4 misfire
P-0306 - cylinder 6 misfire

We checked the timing in measuring blocks 091-092-093, nothing was wrong with the timing at the time.

After the engine was out, timing tools came on nicely, everything was as it should be. Last thing what we checked were the camshaft adjusters. After we opened them up, the bank 2 adjuster had signs damage. As you can see on the video, hole in the plate was slighty worn out.

After qucik chat with the owner both adjusters were replaced along with timing chains and upgraded RS4 bracket. We also reseal the whole engine, changed most of the gaskets, refurb the rocker covers and engine flush after.

Also the headliner wasnt the best, so it was taken out and retrim fully.

Last small bits like rear parking sensor and windscreen wipers were fixed.

This was propably the lowest milage S4 we ever had in! It was a plessure to work on it so the future classic can run again with no issues.

SEEYA in the next video!
