Hey Guys,
I hear this noise from the rear cabin and it sounds like a high speed drill running for about a second at the most.
Has anyone got a suggestion as to what it might be? I only hear it on occasion, maybe once every 25km and it seems to be random but I also think it happens after...

Polo 77Tsi has just turned 4 so needs to be serviced.

However it has just turned over 15,000 km

Which service should I get them to do.

Apart from one 1000km trip it is just used as the shopping basket 25km max with very occasional trips to town 100km return....
