Xenon head light right is weaker than left?

Hi Experts,

Just a question;
During the yearly check of my E53 3.0i (2001), the mechanic told me that the Xenon bulb on the right side (passenger side) is pretty much weaker than the drivers side.
I had a new starter, changed it but the problem remains the same.
I switched the xenon bulbs from left to right and vice versa and it remains the same.
Installed new bulbs in both headlights and problem remains the same...

Is it correct that the right side is weaker than the left side or is there another (known) problem? Maybe drivers side is too strong??

There are no failures when hooking up to my laptop

Thanks!
