![]() ![]() The timing chain tensioner has gone through many revisions before VW/Audi was able to come up with a proper solution that would make sure the correct tension was kept on the chain. The manufacture has recognized the issue of 2.0T TSI Timing Chain Failure, as a result a revised timing chain tensioner has been put to market as an "update" or "replacement" part. HAVE NO FEAR, THERE IS A SOLUTION TO PREVENT THIS LEVEL OF DEVASTATION TO YOUR 2.0T TSI ENGINE! Due to the 2.0T being an interference engine this can cause catastrophic failure of the complete engine, or at a minimum destruction of the vehicle's cylinder head assembly, or un-repairable damage to the engine block itself. When the Timing Chain Tensioner Failure does occur in a running vehicle the valve-train & rotating assembly can spin freely of each other. The service team at PSC has increasingly begun seeing vehicles that have reached approximately 80,000 miles and religiously followed the dealerships' prescribed 10,000 mile oil change interval, coming into our facility suffering the symptoms of a failed timing chain tensioner. The reality is that although the chain itself and the rest of the hardware is well equipped to take 150,000+ miles without problem, the timing chain tensioner is not. The theory behind this move was that a chain will a longer service life, and shouldn’t need to be repaired during the normal course of ownership. The newer 2.0T TSI engines have moved to a "timing chain", which VW / Audi have stated as a non-serviceable item and should last the life time of the vehicle. The 2.0T TSI engine found in 2009+ model year Volkswagen's & Audi's have moved away from a traditional "timing belt", which had a regular service interval of approximately every 70,000 to 80,000 miles. ![]()
