29F3 and 2A13 Codes Together

MichaelP · 03-30-2018, 04:24 PM

I got an SES for the following codes this week, I tried clearing but they came right back.

29F3 Fuel Low Pressure sensor
2A12 DMTL Solenoid Valve Activation
2A13 DMTL Leak Diagnosis pump

Although both fuel related they seem to be completely different parts of the fuel system. Any ideas on which code/issue to tackle first?

If it helps its a 2010 335i 116K MHD Stage 1 Tune which has been installed for the past 10K miles with no issues before.

Thanks

Low pressure fuel sensor first, reset codes and drive for a while, re-assess...

Thanks I’ll start there hopefully it will fix both codes

I had a similar issue. Replaced low pressure sensor, never fixed DMTL before I got rid of it, but the sensor fixed the CEL.
