MHD won't connect to dme

Post by Mato » Fri Jun 09, 2017 7:51 pm

Hi all just tried to flash my 2008 135i using mhd, it read the ecru initially and allowed me to buy the map. Tried to load the map and now the app is saying it cannot contact dme and car just cranks won't start. Any ideas? Thanks

I've had a lot of customers bring there cars to us after trying to flash the ecu this way
If you check if the ecu has communications with a diagnostics to 1st
If it doesn't I would need your car or the ecu Cas and key sent down to us to fix the bricked Dme

Try another otg cable. I had the same issue bought a cheap otg cable was able to read codes etc but when I flashed it failed and car wouldn't start. Got a new one from maplins and flashed first time .

I had to try 2 different leads, one initially connected then failed, lucky I had spares

As above, get yourself a decent cable and try again, mhd should just pick up where it left off and recover it.
