Just make sure the connector clip on,,,,they can be a pain to take off and put on,,,,put a little WD-40 on the hose when clipping back on.

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

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

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

Will do. Thank you for a quick reply.

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

Thanks for the reply! I have 2011 535 X-drive. As per fault code description I found online it has to do with DMTL pump or DMTL wiring. Should I try replacing DMTL pump first? Plus last year my local BMW service center told me my Charcoal Canister is breaking apart as they found some charcoal traces. I’m planning to change Charcoal canister too, do you think there is need to replace canister? Do they ever go bad? How hard or easy is it to replace it myself at home for being a newbie?
