Xhorse Super Chip XT27A BMW EWS3 Car Not Start Solution

 Problem:

Tried to write key 2002 model Mini Cooper EWS3 system with Xhorse vvdi key tool plus using vvdi super chip xt27a.  I converted it to 7935 but it failed several times. The car doesn’t work in any way.

Solution:

Sometimes super chip fails on EWS3. XT27A is not ideal for BMW and Mini (some report signal being weak or losing programming).

Better use original 7935 chip or XT15 7935 chip. XT15 works fine.

But some others find a way to use the super chip for BMW PCF7935.

1). You should set chip on VW ID33 (some also set on ID44). It working always for BMW.

2) or Super Chip converts to 7935, then converts to VW33. Don’t have a problem it didn’t come back.
