Ok good.

Simular problem in my brothers bme540 it was the EWS that time and he strated with new key.

The bmwdealer saw this in the diagnos. The indys told him it was the key after their diagnos two inyds or more. After ordering new key same problem then took it too BMW and they could see that it was a problem with the ews.

I think the indys could see that it was a problem with the antitheft system and then recomended the key.

Im not shore it u should get light with a bad key but hopfule somebody else knows.

Sois it dealer or indys that whant to start trowing part in by ur expense?
