Last year in November, I wrote to Volkswagen asking about their policy regarding vehicles that have not been approved for sale.
ESP from Bosch regarding biodiesel and the crankshaft pulley that detaches.
I had already dealt with the biodiesel damage issue.

As a response now, in April, this impudent letter from the fuel company blames the fuel. I work in the automotive industry myself and know that, strangely enough, BMW and Mercedes don't seem to have any problems with leaks, especially since my car was also approved under the old standard icon_twisted.gif. They will receive a strongly worded reply, which I will write directly.
to the Piech family. That was the first and last Volkswagen I owned. They didn't even comment on the crankshaft pulley icon_twisted.gif.

Are BMW and Mercedes allowing their diesel engines to run on biodiesel?
While Mercedes CDI engines aren't exactly known for their reliability, well...

But I don't quite understand your problem with writing.
The quality of biodiesel is actually playing a crucial role.

Sorry, X-world.

However, the quality of the biodiesel doesn't actually matter when it comes to seals being damaged. This happens with even the best-quality rapeseed methyl ester (RME).

If it were aggressive, for example if it were acidic, it would attack the metal surfaces and cause corrosion. However, that never happens!
Is the filter clogged or contaminated? This can also happen with diesel fuel.

Oh, I just thought that the amount of food consumed might vary depending on its quality.

My problem is that I received a letter in 1999 stating that I would only...

Regarding BMW and Mercedes: If you order the 'REM' package for those vehicles, the pump and seals will last longer. This is also mentioned in the ADAC magazine. A BMW employee confirmed this to me as well.

Oh, well, that's quite funny.

Well, the problems at BMW and Mercedes are more related to the likely (more prone to failure?) CR technology. But that's not really relevant here, sorry.
