Hi all,

Thanks for reading my post.
I have a Mini Cooper S R56 year 2010.
I replaced valve cover (bad CCV), and during the work, grounding wire that attaches to valve cover stud broke off.

The car cranks, but won't start. Throwing U114B U115B U115E codes.
I fixed the grounding wire. reset all the codes in all the modules through ISTA (Rheingold). Disconnected the battery for a few minutes.

Now all the modules work, except the DME is not responding, I get the following errors:
S 0129 "no communication possible with engine electronics"
00D515 "No message DME-DDE, receiver EPS, transmitter DME-DDE"

Did I fry by DME ?
How can I troubleshoot/fix it?

I have a multimeter and an oscilloscope. Does anyone have leads to getting the pinout of the DME?
I would very much appreciate your suggestions.

Thanks!

 

Did you get anywhere with this? EXACTLY the same thing has just happened to me.. earth wire on cover wasn't connected and boom... cranks but no start and loads of modules are showing no comms possible.

 

Have a look at my thread, https://www.northamericanmotoring.co...placement.html
I went and had to get a new DME (used one) that i sent off to PrecissionECU and got it fixed up. (dealer wanted 3000k, precissionecu was 500 cdn, and sent from canada on a monday, got back the following wednesday.)

 

Yea...my DME is currently with the tester to confirm if it's fried. Which is insane... a small earth wire on the HT leads and that's enough to fry your DME!! And lets face it.. that wire is not particularly big or strong so i would imagine easy to break! This engine really is made of cheese.

 

I have since added a secondary ground for that wire, also so that I dont need to worry about it.

 

He ended up cloning the ECU though PrecissionECU

 

I didn't clone, but something similar.

I send my CAS, Key and New (used DME) to precission and they took care of it all!

Was a hellalot less painful then a new DME from Mini.

 

I know lol...i meant the OP got it cloned.

 

gotcha!
