DME updates with WinKFP

Post by spazmochad » Fri Jan 06, 2023 6:23 pm

It's been a while since I did it but these are the videos I have in my watched list which probably helped me through it ("BMW doctor" is best ignored for the most part):

From what I remember there are two ways in which you can flash - have it pick the correct ZB-Number automagically or pick the right one to use manually. I had to do it manually for the DME for some reason iirc. How you pick it is a bit hazy but one of those video shows how to do it for sure. It's essentially finding the current software version (on the label) and going through the pairs of numbers in the updates file index to map through the old software version to the new one. I don't think you need to enter the VIN either if you are simply updating the ECU.

Providing it picks the correct update for you it's really simple, just have the laptop/pc somewhere secure and stay away from the OBD port whilst it's flashing as it will take a while.

spazmochad, I think we've proved by DME is goosed!
bigwinn's INPA could not even find it!
Does your knowledge extend as far as being able to help me sort a replacement?

If you take a piccy of your current DME label and send it to me then I can look up part numbers. Then so long the chip is read-able happy to help cloning it over if needed as I still have the ECU tool and the software setup on a laptop.

Hmmm. Bigwinn's INPA couldn't see it, so that may cause a problem?

It might do, depends if the MPC555 chip has died, the tool hooks up directly to it so just need that to be in working order. Could try reading it to take a backup first?

Have you looked at the harness and pins on the DME? Mine had oil pooled in the one of the connectors, think it wicked up from the oil sensor.

Hey, I'm engine/airframes mate. Your first sentence lost me. :rofl:
But we have checked the connections. All perfect, clean and dry.

I have found a place advertising in Norwich, about 15 minutes from me. I'm waiting for them to reply. If not, whereabouts are you?

Hi mate

really appreciate your help so far on this one

I was thinking on the drive home- is there a bench tool that allows you to:

-take the DME out
-power it
-connect it to WINKFP
-flash the software off the car on the bench?

You can tell I'm a saddo thinking that I could make something to do this....

You can bench read the DME no problem, however if the DME isn't booting then you won't be able to access via WinKFP.

If the DME isn't booting because the flash is corrupt then BDM (background debug mode) using specialist hardware is the only way to communicate with the ECU.

It's unlikely the DME isnt booting due to corruption though so I'd check for water ingress, corroded pins etc.

If the DME is dead, just pick up a replacement from ebay, you can use the part numbers from RealOEM to find one that will suit.

Once you have the replacement you can use https://www.bimmertuningtools.com/produ ... uickflash/ to disable EWS and the car should fire straight up.

Btw, deleting EWS has no negative effects on the car or its security, it simply disables the check performed by the DME to check that it's 'paired' with it's original EWS module. A valid key etc is still required.

Bearing in mind I am very much mechanically biased could you please in simple terms how I would go down this route. Do I still need my vin coded to the replacement DME? How do I make it recognise my key?

The VIN in the ECU is just for reference. Your keys are paired with the EWS module and not the ECU.

So................. apologies for doing this to death.................... I get another DME, tell it not to talk to the EWS module and pop it in. Simple as that? What about software versions? I have found many part numbers that can be retrospectively swapped with mine, so they should work straight away yes?

The software version is largely irrelevant, but for the sake of simplicity id pick one up that came from the same size engine.

Interesting

Anyone got one of the bimmertools on here?
