Hello have a BMW F20 with error 2AB200, atmosferic sensor pressure inside DME plausible.
Ista says replace DME. 
Its possible repair or need replace/clone used.

Thanks

hi, what pressure values do you see in ISTA?

You can open DME and replace sensor (solder old one out and new one in). Did that couple of times. Those usually can be bought from china or from some reputable electronic components dealer.

ISTA says replace DME because dealers are not supposed to be doing that (opening DMEs and soldering something).

do you know where to buy the sensor?

Thanks

I've seen at least 3 different sensors. And did too few to guarantee that you have a particular one. Open DME and look for yourself. Usually, they are clearly seen as quite big "chip" WITH HOLES to let air in, with about 8 "legs". Then go from there.

I guess it could be Bosch SMD284, but you REALLY need to verify that.

P.S. I bought it from this link, but it was 3 years ago, so there may be better sources now. Back then it was either china or this. And this seemed to be reputable compared to china. Shipped, however, through that STUPID global shipping crap .

Check if ecu is dry. Had the same issue with 420d when fuel pressure sensor failed and flooded ecu, car was still running but ecu was full of diesel. Ended up replacing ecu

If you have remap tools and you can adapt any sensor to this application using transfer curve. Happy to help if you go this way... If car is old enough then ecu swap is probably cheap and fast though..

Hello, I bought a used ECU and made a clone and it worked without any problem.

Thanks for help.
