BMW EWS Add Key: VVDI Super Chip or Original Chip?

Question:

To add key for BMW EWS system, aftermarket or original? I programmed VVDI Chips but car cranked not start.

Here are some choices:

1.VVDI XT27A Chip (set as 7935/ ID33/ ID42)

Reviews:

Ak90 can only write on xt27a generated as 7935 id33 and id42

2.VVDI XT27A Chip (set as ID41 Nissan)

Review:

Xt27a is fine don’t use vw 7935 use the Nissan version. It works every time for me. My service vehicle is a x3 with EWS 3 and I also have an x5 service vehicle.

3.New VVDI XT27B Chip

Review:

I use xt27b. The best for all

4.New VVDI XT15 Chip

5.Original Chip

After few weeks all info from transponder use always pcf 7935

Hope this could help!
