Product Details

Unlike "generic" diesel tuning systems, this advanced, self fit chip will be programmed specifically to optimise your Audi A8 MK2 4.0 TDI. 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 when you need them. 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 dynamics and allow you to keep RPM's down by holding taller gears while using less throttle for similar speeds, helping you save fuel. Remember while most tuning companies aim to provide maximum power our aim is to also refine drivability and in gear flexibility, providing a wider spread of usable performance where you need it most!

Better Economy

By making your engine significantly more fuel-efficient, the CHIP Express™ digital tuning system means you can achieve substantially better economy from your MK2 4.0 TDI 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.

Ever wondered why the manufacturer didn't program it this way as standard?

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.

  • Many countries, for example, impose emission controls which are far more rigorous than those we have in the UK.
  • Other countries relate their vehicle taxation systems to power output rather than engine size.
  • Some, like the UK, impose higher taxation for different emission levels.
  • In many cases power is deliberately restricted for future use.
  • Finally the manufacturers themselves often produce several different performance variants of a given model.

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!

Feedback From Our Customers

Benjamin from Gosport with a Audi A8 MK2 3.0 TDI 233 said: I felt after a few years of having boxes from you I would drop you a line to say how good your product has been. I have had two vehicles with CHIP Express tuning boxes. The box from my 2008 A6 2.7 TDI 180 being exchanged and programmed for my 2008 A8. The service was superb and very quick. These Multitronic Audi gearboxes are super smooth anyway, but they became smooth like a payne of glass with the box fitted, especially the A8, which became barely noticeable when changing gear. The power increase was awesome and the fuel economy went up by around 5 mpg which in an A8 is welcome! Overall both of my cars have been even more joyous to drive when fitted with these boxes. I have also recommended you to a few people who bought boxes and have been equally as pleased!
Mark from Newburgh with a Audi A8 MK2 3.0 TDI 233 said: I fitted the tuning box to my Audi A8 3.0 TDI very easily. The car runs so smoothly and has all the power one would need and yet gives an easy 48mpg on a run. I am getting the box reprogrammed for my new car. I have bought my new car with CHIP Express tuning in mind. A great company that has to be backed by enthusiasts. If only they could see our smiles!! Thanks guys.
Colm from Waterford, Ireland with a Audi A8 MK3 4.2 TDI 350 said: Just fitted to my A8 4.2 TDI... WOW!!! I am so pleased with the new performance! With regard to economy, I used to have a 500 mile range but now with chip tuning I have a 630 mile range!
Peter from Richmond with a Audi A8 MK2 3.0 TDI 233 said: It does exactly what it says on the tin! Cannot fault the extra performance and extra MPG. After 9 years would highly recommend and not hesitate to purchase again. Paid for itself in no time at all. One very happy user.

What others are saying...

“May I congratulate you on this diesel tuning product as it has made a noticeable difference to my Land Rover Discovery. I have tried other diesel tuning boxes for my previous vehicles (Kia Sorento, Peugeot 206 and Vauxhall Vectra)... and they all produced slight engine stuttering under certain load conditions. The CHIP Express system does not show any evidence of this and is equal to the likes of an ECU remap (which I have also had done before) for smoothness and noticeable power gains. This would be the only diesel tuning product I would recommend.”

“Be assured, this is NO gimmick. Arrived yesterday (less then 24 hours after the order was placed) and fitted today. The fitting was easy especially with the photos and instructions sent with the chip. The first thing I noticed was the responsiveness of the engine from a standing start, no more lag. I then went on a 30 minute drive both motorway and sideroads and my average fuel consumption went UP from 33.3mpg to 38.7mpg. My motorway speed varied from 60 to 85mph and the sideroads from zero to 40mph. I am so pleased with the whole result. This is worth every single penny paid. Thank you!”

“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!”

“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!!!”

“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.”
