Always when you replace the timing chain Buy the OEM raplacment set. ( Mercedes parts) It usually lasts 300-400k km on a B class. / (Diesel) Yeah it's not like in old mercedes cars where it lasts for at least 800k km. Alo i think a good practice when doing the chain job to change the water pump, thermostat and a clutch job. ( cause engine is out)
TDI. 14 A6 TDI & 15 Q7 TDI. Sep 21, 2020. #1. Just bought a 2015 Q7 TDI with 50k miles a few weeks ago. I noticed what I believe to be a timing chain rattle on cold start. Is this normal? Is there an oil check valve that needs to be replaced or does the timing chain tensioners need to be replaced? Very concerned with it at such low mileage.
