Hi, just bought a 2006 GL. Requested the service history which shows Brabus MBQ16473800 performance kit being installed in 2010 by MB. Is there any way that I can confirm this upgrade is actually installed or is it purely an ecu code upgrade? Would anything show up on a odb2 scanner or would it need to be on the MB computer?

Cheers

It's a additional piggyback ECU, looks like this:

Frequently mounted up in the engine bay somewhere.

Generally to the right of the engine bay, near the windscreen, under a plastic box.
 
Yep mines fitted on a bracket which attaches to the ecu which can be found under the pollen filter
