   usually sync by INPA should solve your problem

   sometimes is help just «reset EWS» in the DME section by inpa and re-align the EWS with the DME

   The DTC is just telling us that the EWS is faulty, just replace EWS the car will start. Done it more than twice, it always works out.

1. E46 320d Car Not Starting/Cranking code 4A42
   

   Hi I have a BMW e46 320d that won’t start or crank.

   I plugged in a INPA USB-obd Cable and using DIS I pulled the following code: 4A42 EWS interface error in the DDE.

   Everything else including the EWS returned with no faults.

   I have looked around in forums and googled this fault but it seems no one has any info on this issue.

   Can anyone please give me some help with this.

   Thanks Addaz ps. This is my 1st post.

3. Sound like you need to re-align the EWS with the DME. Sometimes, not very often, the DME «forgets» the EWS.
   If you only have INPA, there is a «reset EWS» in the DME section. If that doesn’t work you will need to use either progman or such to re-align.
