If anyone has upgraded/changed their HID's (S Grand Touring with adaptive lighting), I'd like to know how the replacement operation went ? I took a quick look and it seemed like a real tight squeeze with an obvious partial component removal. The yellowish stocks look out of place especially surrounded by the crystal clear LED's, and I've already installed LED's in the fogs. Technical info would be appreciated...

Your lamp takes a D2S bulb. If you're looking to match the LED white, you'll want Osram CBIs or Morimoto XB35 5500k. ($180 vs $50).

To change the bulbs, it might be easier to remove the headlamp assembly from the car. From there, remove the housing cap, twist the ignitor counterclockwise, and undo the pins holding in the bulb.

I'm not familiar with the 3rd gen 3s, but with the older generations, that was the process. Generally, changing HIDs is the same process.

Be careful when you change the bulbs. They're fragile and don't snap the return wire or you'll kill the bulb or start an electrical fire when you turn them on.

Careful, I'm not sure the Gen3 mz3s take the same bulb...

For the 1st generation Mz3 removing the headlight is completely unnecessary. I have never once done that on mine, although I've had multiple sets of H7 sized HID bulbs in there.

On the latest M3 (D4S) version...the path of least resistance is through the wheel wells. Pop off the plastic protectors and your there...very simple from that point on. If your fingers/hands are small enough you might even be able to do the passenger side from inside the engine compartment, but there's no way to get the drivers side from there. BTW...I upgraded my stock HID's (4300K) with Osram Xenarc's (5000+K) they're nice, but not a $185 difference from the stocks. I expected a crisper, clearly, diamond white light, but didn't get it :frown:.

Weird, Sylvannias tool said that it took D2S. Sorry for the mis info.
No problem...they were D2S's until 2014 changed to the D4S's. It's my understanding that the D4S's are better designed for projector housing versus the reflector ones.

The difference is no mercury in the D4S bulbs, where as D2S had heavy metals. They aren't cross-compatible though, still need to be application specific. The only HID bulbs in reflectors are D2Rs, "r" for reflector.

Thanks....good to know ! It's tough to keep up with the constant changing technology...
