Hello everyone! I currently have a car equipped with the 1.5 bluehdi 100hp built in 2019. I know the engine has problems with the chain that runs the two cams. I learned that psa upgraded the engine with a new 8mm chain to solve the problem. I want to find the correct chain. Can someone give me the oem code number for the 8mm chain or a place where i can buy it. I dont trust my psa dealer so much and I want to double check and be sure I get the correct chain. Do I have to change only the chain or is it better to change also the cams? My car is still working fine, I just want to be sure i dont break my engine because of this chain problem. Thank you!
