Another W203 No crank , no start
When I went home I turned off the car , tried to reset the error by turning the wheels 3 times left and right (i saw it online it has to do with the steerin wheel sensor or something like that) and the engine light and esp lamp turned off. The day after both of lamps were turned on once again
A few days later in the early morning , I tried to start the engine but I couldn't hear crank but i hear some kind of noise for like 3 seconds after putting the key to position 2
(it happened to me like 3 or 4 times since I got the car but I thought it was something related to the key or the way I inserted the key)
I started the car next morning and I noticed that engine temperature lamp turned on and also both esp and engine lights were on (engine temperature was low since I just started the car and didn't rev at all) .
I went to the service shop directly and for some reason the engine wasn't starting again , no crank but it started after a few attemps later.
For some reason after driving the car after 100 meters the engine temperature lamp turned on but it was red this time .
Strangely the temperature was at 40-50 degrees and it shouldn't light up the lamp (Error name : coolant stop car . Turn off eng.)
I turned off engine as suggested, waited a half of hour and tried to start again but no sign... No crank at all
Tried a few times afterwards but still no luck. After some times it started successfully
I went back home turned off engine and started again and everything is working as it should (expect from the engine light)
My guess is that is something wrong with the fuses/electric part of the car
I checked fuse 52 and is working but for some reason is 30 instead of 25/20. Could this be the issue ?
Can i borrow a 20/25 fuse from another location and put it there without breaking anything ?
Also idk why the previous owner put a 30 instead of 20/25 fuse
Fun fact : i started it now after 4-5 tries and it turned on , for some reason all of lights are off now including engine check light and esp 😶
Any suggestions ?
Thanks for reading it btw 🙃
fuses , it looks like a spider net btw
fuses
The car has some aftermarket mods like heated seats and so on, maybe that's why
1 month 😢😢

The only way forward is if you own a good electrical tester (digital voltmeter such as a Fluke) and a good OBD device for example from iCarSoft or better yet a full XENTRY system.
You need to dig through the electrical mess that previous owners have created for you.
