I took mine out again. Switched the new module to the left headlight and the error moved again (to the left headlight)
Then I took the old module apart and “baked” it in an old oven for 8min (+ cooled down for 30min) to try and “fix” any bad soldering.
In the waiting time I took the NEW module apart and could see that some components were “missing” compared to the old defekt module… perhaps thats why the new module threw an error???
After mounting the old module in the right hand headlight again, the error (for now) was gone… I will test further today and hope the error is gone for good.
Just shows that although the part numbers are correct (identical) doesn’t mean they are in fact the “same”
