Oil Sump Spray Tube: Causes & Solutions

During the removal of the oil pan on a 1998 A6 2.5 TDI with 135,000 km, a damaged oil spray pipe for piston cooling was found. The part was obviously damaged, and it appeared to have damaged the piston. Has anyone else experienced this? Does it pose a potential risk to the engine? According to Audi, the oil spray pipe needs to be replaced (which requires approximately one day of work).

Hi,
Unfortunately, I'm not personally familiar with this engine. However, piston cooling is essential for the engine, especially under high loads. Volkswagen already implemented this feature in the 1.6L turbocharged diesel engine with 70 horsepower. This was for a much less powerful engine, which, as a swirl chamber engine, also has a lower thermal load on the pistons anyway.
