The BEW engine code 1.9 liter TDI (Pump Duse) engine was used in the 2004-05 VW Jetta A4 chassis (aka Mark IV). The BEW TDI engine is driven by a timing belt system which links the cylinder head, camshaft, injection pump, and crankshaft to run in sync. This VW Jetta timing belt system consists of a wear resistant, high strength, corded molded rubber timing belt (a.k.a. VW Jetta toothed belt). There's also an assortment of tensioners and idler rollers to guide and tension the BEW TDI timing belt.
It's very important to service your VW Jetta TDI timing belt. The timing belt, tensioner, and idler components eventually reach the end of their recommended service life. The BEW enigne code Jetta TDI is an interference engine (a.k.a. non-clearance engine). If the VW Jetta timing belt fails, the timing belt system that links the cylinder head, camshaft, and crankshaft no longer run in sync. Close tolerance engine designs allow for the cylinder head valves to hit the top side of the pistons. VW Jetta timing belt failure on these engines will results in catastrophic engine damage (i.e. bent valves and in some cases cracked pistons).
We're pleased to announce our partnership with Schaeffler Group Automotive, one of Germany's and Europe's largest industrial automotive companies who have been manufacturing timing belt components under the official Original Equipment (O.E.) INA brand for decades. Partnership with an O.E. manufacturer means Blauparts can ensure absolute quality control through a direct supply chain. >> Read more about Schaeffler.
BLAU OFFICIAL O.E.™ INA BASE VW Jetta Timing Belt Kits include the same timing belt and timing belt tensioner components that are supplied to VAG. Beginning in May 2013 Blauparts began to include an INA BASE kit in nearly all of our VW Timing Belt Kits. Hundreds of INA part numbers were entered into our database. As of January 2014, approximately 90% of BLAU OFFICIAL O.E.™ INA VW Timing Belt Kits include a BASE INA kit and have been fully integrated to Gen II status.
Gen II BLAU® VW Jetta Timing Belt Replacement Kits for the 1.9 TDI BEW engine contain a preassembled INA timing belt BASE kit. The timing belt, timing belt tensioner, tensioner idlers, and hardware contained in this BASE kit are the same as those directly supplied to VAG.
