Hi I can help you, need more help ???

ECU ISN: E6577A7AAE96AE8CB10E2C8A111008A7 ????

old ECU ISN: EF792DA41E878154AEC0E6BFA75B155D ??

modi (isn adapted) file chk ok,write to ecu and start car ok

[doctore]

help him.....to solved crc

[rob h]

Yes, needed checksum.
The file is allready modified.

Only crc left to be done

Car starts.
Lots of dtc,
Looks like the ECU does not realy match

[figani]

you only exchanged ISN...?
better clone it...

[rob h]

Old ECU death .
No bdm response,

I changed vin, by obd.
And isn by dump, that is all, car starts.

I updated flash online,
That cured nothing

Let me guess, somebody forgot to attach the ignition ground wire and they asked you to replace the ECU?

Check what voltage the old ECU puts out on the 5v rail to the accelerator pedal. Most likely much more than 5v, and thus it destroyed the accelerator.
Disconnect the accelerator pedal and check if you still have the internal error 2BD2.

To get rid of the anti-tamper protection, you need to request the FSC codes for this VIN at a BMW dealer (some people on this forum can to that as well) and then program it into the ECU. It's free, but you need access to ASAP to obtain that file.

DrGini 2.22B is now available for free so you can use that to program the FSC code in the ECU, or else you need to use ISTA/P.

Hello,


So the easier way, would be writing isn from replacemend ecu, in to the Cas3. (Will this requiere programming new keys?)
I dont have ISTA/P, if i have to, i will need to get that.
Tommorrow i will revisited this car, and check the accelaration pedal.

Many thanks for your help,


P.S
The cause,
Car came in to the shop, rattling timing chain, and runs on 3 cilindres.
After replacement of this chain, the car still did not pick up on all cillindres.
So they pulled the some injector plugs, and what have you.
And at some point, the ecu died.
So yes, your explanation fits.

[doctore]

this error are common problem when ecu have deferent part number or data change it,
but you can tr to write original data in ecu spare and post cas eeprom,
keys stay same without programming.

[tomvleeuwen]

ISN does not affect the tampering. There are two ways around programming the FSC into the ECU:
- put VIN of donor ECU in CAS, you'll get the power of the donor car (One or Cooper?) and if the car has navigation it won't work anymore.
- program the software of a One Minimalism into the ECU (that does not need FSC code), but you'll get One Minimalism power.

But it's not that hard to upload the FSC if you have ICOM or K+DCAN (or maybe Autologic) and it's by far the best solution.

This is the cars vin.
The dealer claimed, that they could not provided the fsc.
Could someone help me out?

And this is the donor ECU vin(WMWSR31030T240119)

[tomvleeuwen]

That VIN will definitively have an FSC available. N16 One and Cooper both have FSC in MEV17.2.2, only One Minimalist does not have FSC.

Some dealers don't know where to find it, it seems to be hard to find in ASAP and most dealers never need to download the FSC codes since ISTA/P will download them automatically, but it is possible.

Alternatively, you can program the One Minimalist ZB-nr (8656882) and then download the files and ask someone in the ChipTuning section to tune it to a Cooper.
