Feedback from our Mercedes C-Class customers:

  • Steve from Salisbury with a Mercedes C220 CDI 170 Blue Efficiency said:

    Originally bought this tuning kit for my Mercedes ML280. The difference in torque, acceleration, smoothness and driveability was excellent and immediate. I sold the ML and Bought C220 Blue Efficiency, the same kit that I used for the ML280 was returned to CHIP Express for reprogramming to the C220. It took 48hrs from returning to receiving the replacement and less than 10 minutes to fit, the car has been transformed into the car it should always have been! Excellent service (rare these days), I highly recommend this product!

    I received the chip tuning box next day by special delivery. Opened it up and had a close look then took some time to read the instruction manual before fitting. I did not change the settings on the box, just kept them standard. Left the engine on idle for few minutes and checked for any error messages or lights on the dash, there were none. Car was idling as normal and I could feel the engine running smooth. Switched it off and finished the installation. I could not wait to jump in the car and test drive it! Well, first impressions are great; the car felt very different with a lot more power, acceleration is fantastic. I drove a good 20 miles. Felt like I had a lot more power in low gears as well as high gears and I didn’t have to press on the accelerator to much. The 60 mile journey to work this morning felt so much better. I was hardly touching the pedal at 70mph and the trip computer gave a reading of 55mpg compared to 47mpg average. I will be recommending you to my friends.

    I fitted this little box of tricks and to be honest I am one of the world’s most sceptical when it come to bold claims, also I am no mechanic, in fact the most I ever do is top up the oil, water and tyres. Fitting the unit was so easy even I could do it, instructions so clear you can’t go wrong. My first impressions of what this chip unit is doing is amazing, most of all is the increase in fuel economy, its early days but it looks like a 15% improvement, the power output has also increased by a good margin making the car much more fun to drive.

    First surprise: Having ordered my unit around 4pm on Friday afternoon, I was most surprised and very pleased to receive it first thing on Saturday morning. Second surprise: Ease of fitting. Third Surprise: The overall difference it has made to the car. I own a Mercedes C200 CDI and have always felt that Mercedes got it wrong with this model; however I bought it and am stuck with for the foreseeable future. Your unit has turned it into what it should be, it is now smoother, quieter, responds better and the difference in fuel economy is nothing short of outstanding. Today on a regular trip from Southampton to North London and back I saw the mpg raise from 42.1mpg (average) to 51.2mpg (overall average for the round trip) and apart from road works (M3 & M25) and typical M25 hold ups, I was driving at normal motorway speed (outside lane with flow of traffic).I was that impressed I even stopped in the services on the way back and took a photo of the trip computer display. It was showing the following: From Start 152ml / Av speed 45mph/ 51.0mpg!
