C200k ECU upgrade
Does anyone know of a company/supplier that sells an ECU upgrade for the W204 C200k that can be done through the OBDII port (so it could be undone when car goes into dealers etc) here in the UK?
I used to have a Saab 9-3 and had a BSR PPC (http://en.bsr.se/products/ppc/) which was fantastic, anything similar for the merc would be great.
Any ideas?

I have had almost every tuner here in Europe, and no one can upgrade our ECU.
We seem to have a new type ECU Siemens SIM271KE2 which can not reprogrammed (yet)
They all claim that they can do it, but after i have send my ECU numbers who are on the outside of the ECU they all came back to me that it isnt possible.
There are some W204 C180/C200K with the old type ECU SIM4LKE, but not much.
MKB-POWER also had tuning on their website last year for our W204 180/200K, but think they also thought that we had the old ECU, now it isnt availlable anymore.
But if you have found a tuner, please lett me know.

But may be they can do it, but almost every tuner here say that they cant do my SIM271 Ecu, and they all had the W204 in their list.
You have to check the number on your ECU, you can read it from your ECU.
If your says SIM4LKE than its not a problem.
