Blower engine defective again

Hello.

after my V8 is now doing its service reliably for a few years, yesterday the blower engine left me again. It suddenly smelled sweet during the ride and then came a biting chemical smell that I left the inner space in flight. Since then, the blower engine has ceased to work. The engine was renewed 5 years ago at purchase, a Hella, made in China. After two years he started squeaking again.

Has someone experience with another engine, or. a new revised storage of a new one? I'm tired of swapping this one regularly.

Greetings Stefan
