E63 W212 Limp Mode

[jazz5000]

Hi Guys

Have a 2014 W212 E63.

Car is currently in limp and has the following codes:

P045800 The purge valve of the evaporative emission control system has a short circuit to ground.
P044400 The purge valve of the evaporative emission control system has an open circuit.
P024511 The output for the low-pressure turbocharger has a short circuit to ground.
P023B00 Actuation "Coolant pump of charge air cooler" has a short circuit to ground.
P069100 The output of electric fan 1 has a short circuit to ground.
P06DB00 The actuation of the valve of the oil pump in the combustion engine has a short circuit to ground.
U104787 Communication with the oil sensor has a malfunction.
P059800 The coolant thermostat has a short circuit to ground.
P005700 The output for the heater of oxygen sensor 2 (cylinder bank 2) has a short circuit to ground.
P003700 The output for the heater of oxygen sensor 2 (cylinder bank 2) has a short circuit to ground.
P005100 The output for the heater of oxygen sensor 1 (cylinder bank 1) has a short circuit to ground.
P003100 The output for the heater of oxygen sensor 1 (cylinder bank 1) has a short circuit to ground.

Bit of background info the previous owner had the car remapped and then had also installed down pipes after.
I believe the last four codes will be because of this and need to be mapped out.

Am unable to read engine oil temp and also coolant warning light is on but coolant is topped up.

All the short to ground codes im not sure if this is all linked to one thing causing the rest of the codes?

If anyone has any idea would be much appreciated.

Thanks

Really needs to be seen by an MB indy with Star and codes cleared, car restarted and see what re -appears.
Some of the above codes could be historic. Whoever mapped the car should code out the O2 sensors.

I’d say you have some sort of electrical fault causing most of the codes.

Fuse 22 - 40amp fuse was blown.

Replaced the fuse and car was back to normal with no codes. This lasted around 50 miles of driving and then the light has returned back on.

Does anyone know what sensors are linked to fuse 22 to help with pinpointing the fault.

Getting the car checked by MB Indy tomorrow also.

If i'm correct fuse 22 should be 15 AMP - Fuse 20 is 40 AMP and so is fuse 49 a 40 AMP.
