W212 Incorrect Bi-Xenon headlamp advice

[Carl212]

Hi, I recently purchased a W212 E350CDI after my beloved W211 was written off by an angry fiat 500.
After a B service at my local Mercedes specialist, it was discovered that the driver’s side (offside) headlamp unit is for a left-hand drive vehicle, obvious when up against a calibrated wall. These are Bi-Xenon intelligent light units, which I thought were just about the only upgrade from the old W211’s!

It seems a LHD unit has been fitted by the previous owner. Why?!

There is no option within the instrument cluster for RHD adjustment, so I’m assuming this can only be achieved via STAR on my car. I understand this only limits the units to an asymmetrical mode anyway which isn’t a permanent solution.

I’m looking for advice on whether the issue is with the headlamp unit itself or a separate control unit? My eyes can’t see any difference in the actual pattern of the headlamp units…
The units are around £1,000 (A2128201039)
without the control unit so I would like to be sure the secret isn’t hidden in there instead.

Also, I’m puzzled how this passed a genuine MOT in the UK. Since I bought the car privately a few months ago, I’m unsure of my options. Any insights or advice would be greatly appreciated!

I can't answer why an LHD unit has been fitted, nor whether your issue is with the headlamp unit itself or a separate control unit (but my guess would be the headlamp).

However, if these are Bi-Xenon intelligent light units on a pre-facelift car there should be an option in the Lighting menu for Left Hand Traffic (that's what it should be set to for use in the UK) or Right Hand Traffic. If set to the latter it disables the ILS auto mainbeam and high-speed long range lighting features.
