Peake Code 7F - DM-TL module - ??? - Page 2

Not sure if my code was the same as yours but it was "heating, DMTL module". The DMTL pump (16-13-7-193-479) was replaced the code never came back.

I know that I'm having an issue with an evap valve [code E8 - Evap emission purge valve] that has been there for more than a year now. No way I'm replacing that silly emissions control valve to make the environmental regulators happy. I wonder if that is contributing to the DM-TL error.

That's the only reasons DM-TL codes come on. If the system thinks there is potential for a leak, it kicks the SES light on. BMW did this to satisfy TLEV emissions.

So if I understand you correctly then I get 2 codes for the price of 1?

The evap valve code [E8] contributes to the DM-TL code [7F]? They are not two individual failures??

Crazy talk I tell you. Crazy talk!

The system can throw either code...do you have access to a GT1 or INPA?

Negative.

But knowing that they are related makes me able to dismiss them much easier. I clear the codes and they take a few weeks to return. Though this was the first time that I received the DM-TL code and not the just evap valve.

I just got the 7F code as well. In my case E8 showed up first, then about 200 miles later, CEL came on. Went ahead to clear CEL, then E8 and 7F both showed up. Is the right course of action to replace the filler cap, then the EPV? Has anyone been able to extinguish the 7F code, if so, how?

Code 7F returned the other day. Looks like I've got a new gas cap in my future.

Keep us posted. I went the same route but it didn't help. I even had the dealer scan the beast with GT scanner. Their conclusion was gas cap replacement but no success. So, I just reset the code everytime it comes up until someone can shed more light on the issue.

Thanks

Had the E8 code years ago and had the purge valve under the plenum replaced. Code went away and did not come back for almost a year. Now it comes months at a time

. I believe whatheheck, a member on this board posted that there is another part that is worth replacing down there. The plastic part that connects the two vacuum hoses sustained a hair line crack triggering the E8 code. There is a post on here with pics for more details. I just don't feel like messing the thing right now. If I had known ahead of time, I would have replaced the plastic nipple along with the purge valve. I also replaced the gas cap, but that did not help.
