Hello to the round, I had my timing belt changed yesterday in a free workshop, engine 1.5 diesel 110hp Everything in the package with Wapu wheels etc. I noticed today that the engine has become louder. I first thought ok lies on the new belt, but you know his car stop from the noises ??. Running does he normally no jerking no speed swing, everything normal. What can be there? I have also already telephoned with the workshop. Has times a professional a tip for me that I have a few arguments. Greeting Timo
