Car was fucky already and also needed the yearly inspection, so I figured I would let the workshop also do the oil change and small fixes.
Big mistake. The most obvious fix they didn't do at all (a leaky turbo pipe, most probably), and for my axis hull they ordered a wrong part and they also somehow caused my roof to leak through the top console when it rains.
Also, since they didn't manage to even finish my car in time, I took it back and fixed most of it myself.
Yesterday, suddenly the ventilation stopped working, and today I dismantled the whole interior and managed to locate and circumvent the broken part (now it's just in or off, but it works).
I'm bretty proud of myself
