Release the true power, economy and driveability of your Mercedes - safely, easily and in minutes with a CHIP Express™ plug-in upgrade!
After figures show the power your vehicle will produce on the supplied settings. Max figures show the power your vehicle could produce on a higher setting. More Information
All chips come pre-set for optimal power and economy so adjustment is not necessary: you can simply plug-in and enjoy! Not all vehicles will achieve Max figures when on a higher setting, most standard vehicles will achieve a power between After and Max figures. To fine-tune your system simply press the HIGH or LOW buttons on the keypad to make small incremental adjustments above or below the supplied setting, easy to do and fully explained in instructions supplied.

Achieve a guaranteed increase in performance from a name synonymous with digital diesel tuning systems – CHIP Express™.
Unlike "generic" diesel tuning systems, this advanced, self fit chip will be programmed specifically to optimise your Mercedes Sprinter MK1 211 / 311 / 411 CDI. And because it works in conjunction with your on-board computer rather than altering it, all engine safety functions remain operational. What's more, the system can be easily unplugged, leaving no trace of fitment, returning your vehicle to factory standard at any time.
The CHIP Express™ system simply plugs in using connectors which are identical to those originally fitted by the manufacturer - there are no wires to cut, just follow the supplied photo-instructions for your specific engine and you'll have the job done in minutes. Once installed, you will immediately feel the transformation. You'll pull away with ease, climb hills effortlessly and enjoy extra reserves of power, giving you the confidence to overtake slower vehicles. Your whole driving experience will be enhanced thanks to the significant boosts in performance. You'll feel the improved acceleration, the cleaner, crisper throttle response and enjoy smoother gear changes – turbo lag and hesitation off the mark will be replaced by a faster, more linear and instantaneous delivery of performance; you'll also appreciate a reduction in engine noise. Improvements in torque will transform low end drivability and allow you to keep RPM's down by holding taller gears while using less throttle for similar speeds, helping you save fuel. The common problem of cruise control deactivating on steep hills will also be reduced, making for a much more relaxed and stress free drive. Remember while most tuning companies aim to provide maximum power our aim is to also refine in gear flexibility, providing a wider spread of usable performance where you need it most!
By making your engine significantly more fuel-efficient, the CHIP Express™ digital tuning system means you can achieve substantially better economy from your MK1 211 / 311 / 411 CDI too. You'll drive on a smaller throttle opening for a given speed and change gear less, getting you further on a tank of diesel!
* Typical economy results between 8-16% yet can produce up to 20% depending on engine tolerances, driving style and conditions. CHIP Express™ diesel tuning chips may also increase the maximum speed of your vehicle by up to 5%; applies to non speed limited vehicles only.
Vehicle manufacturers are forced to compromise when they set up the engine's ECU, to create vehicles which will operate in a wide variety of markets and conditions.
To meet all these different needs, they re-program the vehicle's ECU to change the engine requirements. Now, thanks to CHIP Express™ class-leading, state of the art solutions, you can benefit from greater low-down torque for improved pulling power, higher output for better out-and-out performance, and better fuel economy!
Tony from Ruislip with a Mercedes Sprinter MK2 313 CDI 129 said:Received my chip and fitted it to the van, took it for a test run for an hour on the motorway. Just wanted to say it's brilliant, the instructions were spot on, took hardly anytime to fit and delivery of the item was fast and on time. Huge thanks!
“Many thanks for your fantastic service! Unit ordered Sunday, delivered Tuesday am!! Unit now fitted and, as promised, the car is transformed. Winding country lanes tackled quite happily in fifth gear. Cruising on much smaller throttle openings and immediate response on acceleration. The car behaves as a mini car should behave. I had some initial doubts about spending quite a large amount of money on this item but it is worth every penny and would not hesitate to advise anyone to do similar.”

“Your customer service, speed at which you deal with questions and chip (most importantly) are second to none. This is the 3rd variation of the chip that I have run, not only do I see the fuel savings made each and every time I fill up but I also feel the changes in the increased performance too. Far too often people only feel the need to leave negative feedback on a product, it's very rare that people take the time to leave positive comments however on this occasion I feel compelled to do so. A brilliant product and one that I highly recommend should you want to make the most of your cars potential performance and make a fuel saving to add into the bargain. What's not to like?! It's been a pleasure dealing with the team at Chip Express, I just wish everyone I dealt with in life was this professional! Thank you.”

“I must say l'm delighted with the improvement from your chip, its on the standard settings and the difference in the car is amazing!!! I have a smile on my face every time I get in the car, and there is about 5-7mpg improvement. With the mileage l do, l can see myself getting my money back in no time at all. So if your a doubter like me, don't be because its one of the best things l've ever bought!!!”

“A friend recommended one of your "gadgets" a year ago and being not-very-techno (but Scottish and keen to save money!) I bought one. The gizmo has TRANSFORMED the performance of my Land Rover Freelander 2 TD4 AND improved the fuel economy by a genuine 15%; so much so that I have bought another one for our Freelander 2 SD4 which is now a REAL Q-car! (And of course saves fuel...) I have never written a review before (though strangely I do read them and take notice of them, whilst half-believing that they are written by the owner's chums!) so to have made me pick up pen & paper so to speak - I MUST be delighted! Thanks for making technology so simple and so successful!”

“I was a sceptic at first, then after reading the experiences others had been through I decided to give it a go. I bought a new 1.7 CRDI Sportage, not the 2ltr purely for better fuel figures. Whilst this engine pulls very well in standard form, and was returning 44-45mpg even during the first 500 miles I had to go down the CHIP Express route. Well, there is absolutely no point in forking out the extra 2 grand for the 2 litre model when you can get the 1.7 and spend much less to get 2 litre power figures. Excuse the cliché’s, but this car is transformed and by a big margin too. From what I can remember about my 2 litre test drive, my 1.7 now pulls better than the 2 litre version. The low-down grunt is remarkable and pulls like the proverbial train. Fitting took minutes and was effortless, the box was kept on factory settings, I feel there is no need to mess with it. Needless to say I am now a very happy boy and would without question take this route again. I would recommend this to any diesel Sportage owner. Many, many thanks for a remarkable product and a customer service that is rare in this country!”

“A good product and a good service deserves recognition: I fitted a CHIP Express unit to my Insignia. What an amazing bit of kit! My fuel economy and performance went way up and with the mileage I do was a Godsend! On a run to Aberdeen from Hull I returned an average of 62 MPG and I drive quite energetically! I've just taken up the trade in offer and saved a few quid on a new system. The Vauxhall has now gone with 125,000 trouble free miles and I have changed car to a Volvo S60 D3. I'm looking forward to fitting the Chip Express unit and reaping the rewards, thanks guys!”
