X5D new JR auto tune- car will not start?!?!

[Jeffkukuruda]

Gang,
I'm in serious need of some help or ideas. I sent my DME to Jarek at JR auto to be tuned on my 09 X5 diesel. The work was done and returned to me as advertised, however the car will crank but won't start. I have many dash warnings to include...
-AWD and DSC malfunction
-fuel pump malfunction
-tranny malfunction
-malfunction in drive

I also have many codes that will not clear...

-DSC ecu- 6EC4 steering angle sensor, multiple PT-CAN faults D355 D354 D356, message 6F56
-transmission ecu- unknown dtc fault CF61
-instrument cluster- CAN signal fault engine A3AD, CAN signal fault engine idle A3AE
-Junction box passenger- K-CAN fail C919, PT-CAN communication C90B
-Fuel pump- unknown failure CED4

Finally- the engine ecu shows - not present / no answer

Jarek has been trying to help me best he can and has suggested repeatedly it is a bad connection or that I plugged the ECU back in wrong. I swallowed my pride at the suggestion and disconnected all the lever plugs and reseated them. I have now removed and inspected and reinstalled the ecu about 6 times, I'm now sure it is connected correctly. I also have taken the time to pull every single fuse in the trunk, front passenger junction box, and the 5 in the ecu compartment, not a single bad fuse. Could this be a bad relay? Fuel pump relay? Does anyone know what the two relays in the ecu compartment are for? Can I test these? Or how do I tell they are bad.

I need this car to work, I don't know what to do at this point, but it certainly seems the car isnt communicating appropriately.

Thank you so much in advance,
Jeff

So you flashed ECU, its never started with flashed ECU, ECU is not even detected, but you can't see what the problem is?

[Ozer]

Is this a proven tune? One would assume that something has gone during the tuning process, if it was running good prior to removing the ECU

[Socale39]

Sounds like the tuning company needs to step in and provide a little more assistance than "reconnect" the ECU.

[Jeffkukuruda]

It is a proven tune, on the bimmerfest forum all the diesel guys use this tune and they are leading the way with custom tuning for delete systems and such. Just wondering if there's anything else I can do on my end prior to having to resend them the ecu.

Anyone else seen something like this?

how's your battery level? Try putting it to a charger for a while and then see what happens. I know a low battery symptom is all kinds of unrelated errors popping up like this. However, I doubt it's that simple since a reflash was involved, but I guess you never know until you try

[torqueisking]

does it crank at normal speed or slower?

[Jeffkukuruda]

It seems to crank normally no noticeable change compared to when it was running fine.

to wrap this up.... i sent the ECU back to JR Auto again after the power test, he cleared the ECU reflashed it and road tested on a vehicle. I got it back today and this is what i was expecting! What a difference. I'm beyond happy with the tune now. Working with JR Auto to iron out the shipping fees. I recommend this so far after a 30 mile test drive.

If anyone has questions, im happy to answer.

Good to hear everything worked out good for you. These cars really wake-up with a proper tune.
Just want to clear 1 fact: to "test drive" your DDE in another car, Jared must have your CAS and key, or he must have a pretty decent and expensive equipment to change the immobilizer codes, which in this case is a 128-bit encryption between DDE and CAS. As a matter of fact, if he had even connected it to a car the first time he would have figured out the reflash went south and avoid the complications.
