Hi everyone. I was updating all modules in my 07 328i with N51 using ISTA P and at the end of the session I got non comunicating DME and EGC. Car was fine before,no issues at all. I tried to program few times again,with same results. Car won't even crank now,transmission would not let me shift to any position.
All other modules programmed and coded fine,but the DME and EGC did not. Computer cannot idetify those two. This is very unusual.
Did anyone seen anything like it?
I really hope It didn't damage the modules.
Thank you for any input

Sorry to hear this. Additional details might yield more input.

You mentioned the EGC...did you mean the EGS (TCU)?

What type of DME? MSV80?

Are you using an ICOM or a K+DCAN cable?

Are both ECUs red on the ISTA/D control unit tree?

Was the car connected to an external power supply during the flash reprogramming process?

[michal123]

Car was on external power during programming.

Both K D can and MOST cables were used

DME and EGC (TCU) are displayed yellow on ISTA D

I can't remember what DME is in the car. I will be on it again tomorrow,I'll check that

That's great news, the ECUs aren't bricked. Yellow just indicates that they have codes stored in fault memory. Read the codes and go from there.

[michal123]

Thanks
I tried to erase all faults already,but It keeps the same faults even after the reset.

I will try again tomorrow and post some updates on this

[michal123]

I almost seems like the DME and TCU is not awake when the ISTA tries to interogate them

Use expert mode and program just faulty modules first. All be ok.

[michal123]

Update

DME is damaged because a failed program/coding

Just ordered a new one
That is my Christmas present to myself...

You can try and recover the modules with NFS.

Also, I bet your power supply is not actually a power supply. A power supply that is capable of keeping voltage stable in these cars runs $500+

All the cheap chargers you see saying they can provide 50A, 60A, etc are not good enough....it's because they provide bursts of current, not continuous output. You need a charger/power supply that is capable of supplying CONTINUOUS power, not intermittent/pulsed.

We tried everything,its dead.
The power unit is Deutronic DBL 1600 . Its definitely not a cheap unit.
Something went wrong,whether software or something else,hopefully get the car up and running soon.

Try expert mode in winfkp. You probably did not kill anything. Sounds like a power supply issue. Get winfkp to recognize the units and reflash with the correct software.

We brought up the TCU back to life.
TCU wasnt responding because the DME has been dead.
I tried osciloscope measurements and pretty much everything points to a faulty DME.
I will update some more info tomorrow
Meanwhile I thank you all for your inputs.

Can you show us some screenshots? I never seen dead ECU which shows yellow in ISTA. If really dead just use BDM.

From data sheet: "1 minute continuously followed by a cooling period for approximately 4 minutes. "

Not continuous operation....

Actually, the DBL-1600 is an officially approved charger/power supply by BMW for flash programming. However, it should be set at 14.8v for flash programming.

It's also approved for use with the F80 M3/M4 with the new Lithium-Ion starter batteries as long as it's configured properly. Otherwise, damage to the batteries can result.

If it's SPECIFICALLY packaged for BMW yes, but there are also versions that are not approved for BMWs.

All DBL-1600's are approved (at least the -14 variants), there is no BMW-specific Deutronic charger. The charger you get if you ordered the BMW part number through APINET is the same thing you'd get if you ordered it directly from Deutronic.

Although most dealerships don't buy them, a lot of techs use the SnapOn version of the Schumacher INC-700a which works on pretty much everything.

Update.
After replacing the DME everything went well. Programing and coding.
Car is good now and actually better than before.
I still don't know what exactly happened

Using ICOM A or A2?

ICOM A was prone to overheating and failing during programming...hence why they made A2.

I have flashed A MSD80 using only a KDCAN cable and WinKFP, it took 5-10 minutes. Highly recommend attaching a power source, otherwise you risk bricking the DME.

If you are flashing just the calibration file it can be quick 10-20 minutes. If you update the program or boot loader it can be an hour. Either way it's not worth the risk. Use a charger!!!!

And now there's a ICOM A+B+C Next coming in January. Complete redesign over the A2. And a complete set will be *MUCH* cheaper, will be about 500-600 euros.
