2005 E87 116i I am trying to update the DME

[matthewobrn]

Hi All, I bought a car about a month ago and it is running a bit rough since the day after I bought it. (typical I know)

I'm getting a 2A83 Error on the DME: VANOS INTAKE

I'm also getting misfire errors on cylinder 1. I have ordered coil packs and plugs as I know this is a common problem on the 1 series.

The weird thing is it isn't holding onto the error codes it generates.
I need to drive the car and catch the errors before the ignition is turned off. Once I turn off the ignition it loses the error codes.

I would like to update the DME software or at least re-write it with factory in case it has been tampered with.

I have inpa running and communicating with the car.
I also have ista+ working on the car too.

The ZUSB I got out of inpa is 7553350 and Winkfp with the V67.1 sp-daten and Winkfp is not finding a match for it (Error 704).
Using FindECU with my ZUSB and VIN I get an error saying "5 variants found, but they are not applicable for this VIN"

I then jumped onto realoem.com and looked up the ECU part number. ISTA+ is giving me 7550688 as a part number, realoem.com is listing this one: 12147550689 but that is ended. The replacement is also ended: 12147557810
The current part number is: 12142461574

Can anyone tell my if it is possible to update my current DME and where do I start?

Thanks in advance.
