Situation:
Very nice low mileage 2003 MB E W211 500E AMG edition, Ex Japan, LHD.
Anual vehicle inspection: failure!
Why?
Rear fog light right = bright, the left is dimmed. (Japan setting)
In Holland we have to have a bright one at left side, none at right side, OR both sides bright.
I thought i could change this myself, by altering settings with Xentry software.
Was able to change it indeed, now bright one at the left side, dimmed at the right side.
Not exactly how it should be, but inspector was ok with this.
But, since then......... SRS light on, display showing SRS failure.
Started looking everywhere in the system, changed things back and forth, but not finding a solution, felt stupid.
The altered fog light setting must have changed a country/steering wheel setting in different modules, causing conflicts, see picture:






Needed help desperately, so messaged P.A (Benzninja)
Moments later he hooked up to my system and has been busy till 22.00, solving my SRS fault.
Meanwhile altered the fog light setting also, making both fog lights bright, according to EU rules.
Great, all happy.......but after some last checks, we experienced some new "things", like having weird mirrored functions.
For example: when adjusting the drivers seat, the passengers seat started moving, when moving signal lever to the left, the right front signal light blinked......panic!
A short message about this new problem, resulted in a reassuring message in return: "call me tomorrow at 10.30, trust me, we will solve this".
And he did!
Just before he hooked up, i found myself brave enough to change the steering wheel position in the Central gateway back to LHD.
Suddenly, the mirrored faults where gone.
So it had to do with conflicting steering wheel position settings in modules.
This is where Benzninja came in and started working.
Unbelievable how skilled this man is with MB software and electrical issues.
In a short period of time, he solved the problem and cleared all faults!
When i would have brought this car to a dealer service station with these problems, i would have had to sell my house i am afraid
And of course i learned a very important lesson: IF you are brave enough to change things, make log files before, or at least make a picture from the current settings on your screen.
Had to bring this to you guys.

Again, thanks a lot Benzninja!!
