A6 1.8T awt oil pressure light
I had the dreaded oil light come on along with bad noise form the cam chain, fearing the worst i removed the cam cover and all is looking ok, no scoring on the cams that god. I have a replacement tensioner on the way and intend to drop the sump to check the pick up pipe.
The breather thing was quite blocked as was the metal pipe that joins it- nothing else has shown any sludge signs including under the cam cover- very clean infact.
Could a failed cam tensioner (electronic type) cause a drop in oil pressure or should i look else where?
