Hey guys, looking for some help and knowledge concerning my 2011 BMW E90 335i xDrive.

I am having a check engine light for these following two codes:

3226: DMTL leak diagnosis pump, activation : Short circuit to earth.

3227: DMTL leak diagnosis pump, activation: Line disconnection.

I also have a random iDrive message saying my rear left light is malfunctioning, but I can confirm it is physically working.

Knowing that the DMTL pump is at the rear left of the car, I was wondering if it was possible that the light and DMTL share some electrical lines that are damaged or were eaten by an animal.

If anyone knows the electrical layout of the wires and could help me it would be greatly appreciated.

It might also be just my battery struggling with the cold.

This is mostly all stereo and entertainment issues.
Also there may not be much knowledge of non US models here.
Always check the battery on these before doing anything else.
You used to be able to get schematics online but now you need
a copy of IstaD with the attached database.

Are you sure your gas cap is on tight.

Plenty of stuff on ytube about this

Perfect thank you, I will move the post!

But yes first thing i think was screw the gas cap on, but ill have to take a closer look at its gaskets.
