1. When I fill up my needle goes exactly to the 80 as it should be. but when I drove the first 50km it only shows three-quarters full.Then I go immediately refuel just fit in about 8l again and the tank indicator shows again nicely full 80l. Is that normal that the display sinks the first km so fast??
2. My radio reception has somehow become very weak. Is there a booster for the rear window antennas somewhere? If so, where?
I'll say thank you.

Brakes is the pointless conversion of valuable speed into useless heat
