Afternoon all,
Fairly new user here, and I'm hoping you lot will be able to help.
I had my new 63 plate C250 cdi coupe remapped about a month and a half ago, and have only just got round to putting it on the Dyno, due to holidays and other commitments.
I had noticed a rather obvious flat spot just after 3k rpm, which i reported to the Mapping company as im sure it wasnt there before the map.
So Saturday i took the car to my trusted garage, where ive had my last 4 cars dyno'd before and after, all producing exactly what they are meant to.
This time around i didnt get chance to do a before run whilst the car was stock, but the results after the remap were shocking.
After shelling out £420 on a remap the car is only producing 203.4BHP and 380lb/ft.
Which as your aware is 0 bhp and 11lb/ft more than mercedes are quoting as a stock figure.
The graph does show a large dip just after 3k, as i thought. It drops about 35bhp then climbs back up a bit at about 3750rpm. The Tester commented on this and said its very noticable and he didnt need the graph to know that, which confirmed my problem.
I have gone back to the tuning company in question to ask for the map to be removed and a full refund given, and even said i will drive to them for this work (which will be a round trip of 200 miles).
They are fobbing me off with loads of different reasons as to why they wont just refund me. Blaming the Dyno, which i know to be 100% correct from past experience/saying the car is faulty (Its brand new with only 5k miles on it now)/Saying that the power quoted by mercedes is only a maximum and all cars wont meet this criteria (if they dont make the exact figures surely they would be pretty close??) etc etc
A couple of questions for people here, may sound silly but im new to Mercedes:
1. Is there a difference ECU wise between a BlueEfficency model and a non-BE model??
2. Could the tuning company have used the wrong map if there is a difference?
3. How would you go about dealing with this??
your response will be greatly appreciated as im getting a bit irate with the company now.
Cheers for reading
