I have a bad connection on my speedometer and i have to slap on top of my dashboard to get my trip to work is there anyone who has a solution to this

Most likely, you have cracked/broken "soldering joints" in your instrument panel circuit board. This is a fairly common issue as these cars get older.

This can either be solved by buying an new instrument cluster (if you happen to have A LOT of money - part number is 441919880X for automatic cars, price in Germany: 1.112,65 €) OR you take everything apart and re-solder the connections on your instrument cluster circuit board.

There is already some good advice in the FAQ section ( in German, use babelfish to translate or ask if you have questions:
1.) how to dismantle the dashboard
2.) how to take apart the instrument cluster
