VW and Audi 2.0T TSI Engines had some issues relating to the lower timing chain tensioner. This includes both CCTA, CBFA, CAEB and CPMA engines from 2008-2015. On this model these was an early version of this tensioner that may fail losing its hydraulic tension.
When the 2.0T TSI Timing Chain Tensioner Fails it can cause the intake or exhaust valves to contact the piston while the engine is running. If this happens you will need the cylinder head to be removed and the valves to be replaced. At this time you would also need to verify there was no further damage done to the pistons, cylinder walls or cylinder head. This repair would cost $2-4K depending on the damage done.
How do you know if this happened to your vehicle? If this tensioner fails you could have any of the following issues. Engine rattling noise at start up, No start condition (because the timing chain has jumped and you likely have significant engine damaged), as well as fault codes P0016 (Crank/ Cam position sensor correlation) or P0328 (Knock Sensor 1 Circuit High Input).
If you have a TSI you should considering replacing your tensioner as a preventative to ensure your engine does not jump timing and cause significant damage to your engine. We have heard of these failing with fairly low miles (30K) on them. This part is found on the passenger (Right) side of the engine and the lower timing chain cover must be removed to access it.
What vehicles are affected?
Its difficult to be certain but all of our experience has led us to believe that any 2.0t TSI engine up to 2013 should be checked. Its often been said some 2012 model have the old and some have the new. Since we cant be 100% certain we recommend checking to be certain.
How Common is this?
It still remains to be seen how common this is, but here are my thoughts. This issue it common enough that you absolutely should have your system checked. Why? Because not updating your tensioner and continuing to drive is a pretty big gamble, engines are far more costly than a timing chain kit update.
What should I expect to pay?
This is not a simple repair, realistically, it’s over half a day of shop time labor for updating the tensioner. However, doing this will ensure you get the newest revision in your vehicle, which should prevent future issues.

While you are looking at the outside property, take a look at cars in the prospective shop’s parking lot. Are they the same model as yours? Ideally you want a shop that specializes in your car type, we’ll talk more about that later. Are the cars waiting for service about the same type, Audi, BMW, Volvo, and vintage as yours or older? A parking lot with late model cars generally means that the workshop is keeping current on technology, and is likely properly equipped to service your car. Take a critical look at the condition of the customer cars, this is almost as important as their age. Do the cars look well maintained; or are they damaged, dented, held together with duck tape? If it looks like a car you’d be uncomfortable parking next to, then this may not be the right place for your car. If the cars in the parking lot look attractive, then the shop is doing a good job making their customer’s cars last.
The best service facilities want to have an ongoing relationship with you and your car. Ask about their after-service follow up – do you receive a call after service, thank you cards for referrals, does it seem like they appreciate you as an individual? Do they provide free service reminders for when you car should be serviced in the future?
