Hello Club Touareg Community,
I am the second owner of a 2014 CNRB v6 TDI treg with about 64,000 miles. I have noticed a small ticking noise about 6 months before I uploaded a Malone Stage 1 Tune. (Note the entire car is stock besides that tune + the Cayenne Trans map). Now 6 months later the ticking has gotten more noticeable and concerning.
While doing research into the possible reasons for the ticking noise, I learned about my injector deviation, and I was sure that was the cause. My deviations were off great then +- 1 units rising to sometimes +-2 units or worse when accelerating.
So I bought the tools necessary to remove my diesel injectors. I took off the two injectors furtherest away from the from 3 & 6 (sourcing this photo https://www.audi-sport.net/xf/attachments/198915/). I bought OEM copper crush washers and new stretch bolts. I cleaned the two TDI injectors that I had removed and put them back. I inspected my injectors and the tips had mushroomed slightly, enough for the copper washer to have wiggle room. Which made reinstall a bit more annoying.
After doing all this I checked my injector deviations and they were much better! I now range from +-.5 units, rarely reaching +-1.0 units. But the ticking noise is still there!!!
My next steps may involve cleaning out my intake manifold, and installing an oil catch can before my EGR valve. This would be to prevent the carbon build up.
I don't know what may be causing this ticking noise and I would prefer to fix it before a bigger issue occurs.
Attached below are some OBD 11 logs, after doing my injectors I think I got a coolant temperature sensor issue but I am not 100% sure. The Sensor "A" Circuit fault has also been there since before the Malone Stage 1 Tune. And VW dealership replaced the sensor for me but the fault came back a week later.
Also attached is a video of the engine ticking noise.
Thank you in advance,
LZ
