Intermittent running issues with E87, 120D. Auto electrician condemned the ECU and sourced exact part number used ECU.
Bosch DDE 7 798 180
Have read ISNs from all modules.
Fitted donor ECU and have coded/programmed it.
Car would crank, but DDE:EWS Tampering active would remain in the ECU DTCs
Read posts on here about writing the donor ECU ISN to the CAS, have tried that but it won't allow me to sync the CAS/DDE on completion.
Now left with a car which wont run on either CAS ISN with either ECU
Can anyone advise how this procedure is supposed to happen please. I'm now wishing I had just paid to clone it using KTag but was told Autohex would solve.
Thanks
