Part 2:

Then look for the fuse box, which is secured with three Torx screws, remove these.  Then tilted it over and disconnected all plugs.







Then disconnected the engine management computer from the fuse box. Removed the relay and clicked apart the fuse box.





The soldering that should be defective was also present in my fuse box. The soldering had come loose all around, there was also very little tin on it.





First removed the old tin and resoldered the connection as it should have been soldered.



To test it, everything had to be put back together first. After the fuse box, dashboard and all other parts were reinstalled, the - pole was reconnected.

Then the big moment, luckily he did it

I used this video together with the workshop manuals as preparation.



Thought I'd share the repair with you, it might be of some use to you or someone else. When you bring it to a dealer, a new fuse box would be ordered and this would be a very expensive repair. The fuse box alone cost around 500 euros. Now it took me a total of 3 hours and it only cost a little bit of solder
