Default Repairing damaged 2013 2014 F Series ECU DME TMAP ground trace - 06-20-2015, 02:26 AM

Hi guys

A while ago I was unlucky to damage my ECU by letting the USB get in contact with the 12v rail. This burned the TMAP ground trace in the ECU, which meant that the TMAP sensor did not work and that I got P0238 and P007D. BMS/Terry know about this issue and there is a "quick fix" solution on the last page of the F30 install manual (PDF).

That solution is not good enough for me though, so today I got my ECU repaired so I no longer have to jumper the TMAP ground. BMW will replace your ECU if this happens to you and hand you a +2000usd bill (thats what I heard). It cost me 60usd to have it repaired + my own labor removing/installing the ECU (http://f20.1addicts.com/forums/showthread.php?t=1123651).

Hi there,
Thanks for sharing this useful information. Am also communicating with Terry on this to fix this issue. A question I have is it oil/grease we see on the dme board? Similarly, mine has oils as well? Could you advise if it's normal? Thank you in advance. Best regards.

No I believe that is some sort of wax or soldering flux - normal. You also got unlucky with your USB cable?

Any electronics repair shop that is familiar with board level component repair should be able to knock this out for less than an hours labor. I've done this exact repair for Porsche as well as BMW ECU's. I would not attempt this as a DIY soldering project as you can easily ruin more than board traces if you are not careful with ESD and heat. The BMS work around is more than adequate otherwise.
