Sorry to butt in on this thread, but I have a 2005 (late I-6) S211 E320CDI. After replying to a recent thread in the electronics section regarding the front power socket fuse in the engine compartment fuse box (the secret one!), I have been into mine to change the front power socket to always-live.
Whilst I was in there, I noticed quite a lot of wiring over the top of the fuses and relays, and these are absent from the photo which Diesel_Benz provided in the fuse thread. This got me thinking. Being as how the ECU is in the same enclosure, how can you tell if you have a chipped set-up? Is there an easy way to tell?
I had never considered this possibility before, but the previous owner left some other goodies installed and it would not surprise me in the slightest if he had had it chipped.
Any thoughts would be welcome.
