I have been researching this for a while and have not been able to find one. I know the CSE Turbo has a timing CHAIN but I think the CS Turbo only has a BELT. If I am wrong will someone please send me a link to verify this. My car is making a rattling when stopped at lights buts rides smooth when driving and it happens mainly when cold.
Any advice from Saab Experts would be greatly appreciated
