BMW DMTL pump EVAP system description.

A few minutes in the fender talking about the evap system before I put the car back together.

[@mikezurawski]

You are awesome. Thanks. I'm replacing the DMTL tomorrow.

[@POMAH_MOHISH]

I have same code e92. I did a fuel pump upgrade to a bucketles fuel pump and forgot plug in one of the dmtl lines and left it in the the tank. After that I got code p1447. I fixed the line and replaced the dmtl pump and the charcoal canister and still keep getting p1447 can there be any other causes for that code?

very useful information thanks

I have 2012 650i bmw I wanna change My carbon canister and leake detection pump do I need to program it after or no?

[@OGGarrettsGarage]

@ruelbautista9966 I have had only older bmws. On my older stuff, there was no need for scanner use after evap system repairs other than clearing the fault codes. Good luck!

my x5 2001 e53 has an horrible smell to smog and smoke when i press the gas pedal hard, so horrid that i cannot drive it anymore, any clue what could cause this, i recently changed o2 sensors and catalityc converters. i have two years dealing with it, please help me.

[@OGGarrettsGarage]

Is it a v8? Those are known to smoke if the valve stem seals go bad. It's a complex repair if that's the issue.

Does the fuel pump have anything to do with fuel pressure and a evap pump not the vacuum but the actual pump I'm getting air inside my fuel which is making my fuel pressure go down

[@OGGarrettsGarage]

Air inside your fuel? Reduced fuel pressure? If I had to guess, I'd look at the fuel line between the tank and the fuel pump. Sounds like there might be a small leak allowing air to get pulled in. Just a guess though.

[@TIHIS]

@@OGGarrettsGarage checked... Are you talking about after the pump there's a rubber hose that goes directly to the fuel pressure regulator I'm pretty sure my fuel pressure regulator doesn't have a vacuum hose and I'm also noticed that this isn't a vacuum system There's an actual vacuum pump on my system I don't know what's causing the air that get inside the system there is a vacuum hose that comes off of my intake manifold and goes straight into the purge valve charcoal canister but how is that causing error to get from the charcoal canister into my fuel

[@TIHIS]

@@OGGarrettsGarage on my intake manifold I got two vacuum hoses one's going to the charcoal canister and the other ones going to the purge valve

Awesome video make more

[@nationsmostwanted]

Does red white wire suppose have 12 volts with key on?

[@POMAH_MOHISH]

What would happen if I flood the charcoal canister with fuel? Would I get constant dmtl p1449 codes?

[@OGGarrettsGarage]

Not sure, but I think if a charcoal canister gets saturated with liquid fuel, it's pretty much done. It's supposed to only handle vapors. Maybe you can find a replacement at a salvage yard? Good luck!

[@POMAH_MOHISH]

@@OGGarrettsGarage I will and I'll leave a reply for other to know

[@ishd1144]

any updates? im currently running into this issue, i replaced mine with a used one and the filter that connects to the dmtl pump, it leaks gas, any advice?

[@bushuboy]

Hey buddy. I getting a code p1434. I already change the purge valve but my next target was to replace this part. the problem i'm having is that the car idle when I take my foot off the padel between 40-50 mph. what do u think. I also replace the MAF and still no luck..

[@ttramsey]

Real good video. I have a question. When the DMTL pump goes bad what kind of symptoms will the vehicle show other than a check engine light?

[@OGGarrettsGarage]

There are no other symptoms that I'm aware of. It just tests for airtightness. Thanks for watching.

[@MrBakakeng]

Hi will a bad still cause fumes to cause the gas cap to get wet? Thanks nice video
