    I’m looking to replace my dmtl pump on my f10. Any info on how I can access the area?

    I am getting a P0456 code on 2012 f10 ( 528i)is this related to DMTL pump issue


    • I’m sorry I don’t use the P Codes,,,,,I just know the BMW codes,,,,I did read up on-line about P Codes,,,,Code 0456 sound like a gas tank venting leak,,,,your car might have a Dmtl or a nvld system,,,,your car came with either one,,,,,it hard to tell until you remove the left rear wheel and wheel well liner to see which system you have.,,,,sorry I couldn’t help you on this problem


      • Mark fernandes says:

        I will try to get the codes also if it does have he DMTL pump what do i do does it just need a cleaning or what parts do i need to replace and is the same thing called purge valve ??


      • If you have a Dmtl pump,,,,their is the Dmtl pump and the purge valve which is in the engine compartment,,,,,Dmtl pump is in the right rear wheel well,,,,if you have a nvld it’s also in the right rear wheel well


  3. Can you please recommend a BMW diagnostic scanner tool that will read BMW codes or both P codes and BMW codes i.e brand and model

    Does 2013 535xi comes in 2 styles, DMTL and NVLD or just one? I need to replace the Pressure Switch, Leak Detection due to Fuel Small Leak and want to know if there are more than one kind. The http://www.realoem.com states that the part was updated to a different one. Do you know if this is Plug-and-Play or additional items need replacing? Thank you


    • You just have one,,,,either dmtl or NVLD you should have a NVLD,,,,when replacing the NVLD pressure switch also replace the dust filter with it,,,,it is all plug and play and clear faults


      • Eugene says:

        Will do. Thank you for a quick reply.


      • Eugene says:

        One clarification required. In your description above you are stating Right and Left Rear Tires. in previous models (E36, E46) the purge valve located behind Passenger Rear Tire. Does F10 location the same or it has been moved behind Driver’s Rear Tire? Thank you


      • Passengers side rear tire wheel well,,,,remove the right rear tire and the plastic liner
