Hi, I am buying a 57reg E320CDI Estate, its listed as having a factory Brabus upgrade, is there any way of telling if its had the engine upgrade or just the wheels and styling. It has the Brabus badge on the engine cover, not sure if this is significant?.
But the tuning chip will be a little box somewhere in the engine bay with green logos and PowerXtra on it. There will also be the additional wiring loom for it.
On the CLS320 the tuning box is located under the cabin air filter positioned top right of you photo under the plastic cladding.
