G30 Headlight Problem

G30 Headlight Problem
I'm in trouble with a 2021 Model G30. I did the tire pressure sensor removal on this car first. The proximity sensors on the vehicle were failing. I activated the close range sensors by adapting with ISTA. Vehicle owner requested feature activation. I activated the feature with Bimmercode. Now the vehicle has a fault record on the left headlight. I'm doing a headlight function test with ISTA, all tests are OK. I restored with Bimmercode. I coded the vehicle by installing a solid used headlight, the result did not change. Has anyone dealt with this bug?

Error code : 8059A7

RE: G30 Headlight Problem
You are REALLY brave to use bimmercode on 2021 biggrin IMHO it looks like invalid coding. Or even wrong CAFD injected (which bimmercode likes to do).

What do you mean by IMHO? I don't understand I updated to BDC, BDCGW, FLE systems with Esys. I did cafd coding. There was no change.

RE: G30 Headlight Problem
What do you mean by "updated"?

I don't know WHAT function you "added" using bimmercode, so I would check whether CORRECT CAFDs are written into all units (especially FLMs & BDC).

I undo the change I made with Bimmercode.  Then I injected cafd into the existing ecu in the vehicle with esys.  The problem did not go away, I programmed with stock FA to BDC, BDCGW, FLE ecu's.  Where could the problem be?

RE: G30 Headlight Problem
Need try to code FLE 43 (Left) with Esys, should all back on place "as you used Bimmercode previously" - never use it on new cars!!

biggrin Did you code the FLE? 43 left one

Yes. I can coding and programming with online Ista. The problem is not software.  The headlight itself has a problem.  We need to find the source of this malfunction.
