DMTL 2A12 2A13 2A18 Help!

Fb2017 · 08-10-2018, 07:45 AM

Hello everyone. I have been looking around for the best way to rid the car of the above codes. A few forums have mentioned the wiring harness being damaged and a few others me tion that the pump needs to be replaced. Since the placement of this pump varies, I wonder if the wiring can be faulty/damaged on the 328i cars since they have the pump relocated to the rear passenger side.

Hoping for a quick fix but will order a pump if needed.

Codes pulled are the following..
2A12,2,DMTL solenoid valve, activation
2A13,2,DMTL leak diagnosis pump, activation
2A18,4,DMTL, heater: activation

Considering the codes are for the pump heater and pump activation/functioning. I would assume its a wiring issue.. all help is welcome

Car is a 2009 bmw 328xi

Could the pump itself be bad?
