Hi all,

My A4 is making a constant ticking sound at idle, I also think I have an issue with the N80/charcoal canister as I can't put fuel in easily.
The cam tensioner has just been done, and oil pressure is 25PSI at idle (hot), 30 at 1k, and 60 at 2k. It does have a REVO tune and metal injector cups.

Apart from this ticking noise, the car is running perfect.

Any help would be great as it's driving me mad

Sean

P.S. I have a video of the noise if you want it
