| Re: Knocking sound
There is a fix for the KNOCKING sound. Cadillac has a TSB out on this. They replaced my EVAP Canister Part Number 15941577 under warranty. Too early to tell if the replacement corrected the problem - will have to wait till the weather cools off to test.
After reading the other posts on this condition I had pretty much resolved my self to accept it as it was so common and there did not appear to be a fix. I had my car (2006 DTS Performance) in for an oil change and while waiting I mentioned to the service writer of the KNOCKING and he knew immediately what the problem was and he told me there was a TSB. |
