Hello,

i have to gorget to delete the rear O2 Sensor!

So i correct this:

10/01/2014 07:02:53  Scalar:    CDHSH changed from 1.00  (0x01) to 0.00  (0x00).
10/01/2014 07:03:00  Scalar:    CDHSHE changed from 1.00  (0x01) to 0.00  (0x00).
10/01/2014 07:03:27  Scalar:    CDLASH changed from 1.00  (0x01) to 0.00  (0x00).
10/01/2014 07:03:48  Scalar:    CDLSH changed from 1.00  (0x01) to 0.00  (0x00).
10/01/2014 07:16:32  Scalar:    CLRSHK changed from 16.00  (0x10) to 0.00  (0x00).
10/01/2014 07:18:32  Scalar:    CLRSKA changed from 1.00  (0x01) to 0.00  (0x00).

Is that enought?

Can someone correct the checksums again, please?

ME7Sum v0.1.0 or later *may* work on this bin, but no guarantees!

I would appreciate you testing it, but you should have a backup ecu (in case the car doesn't start after a few weeks) or way to bootmode the image just in case...

It is a risk, so I can understand if you don't want to gamble.

I tried with the latest ME7Sum.
