Feedback From Our Audi A6 Customers

Steven from Shifnal with a Audi A6 MK4 2.0 TDI 190 said: Holy Dooley... I'm impressed! First off, I ordered the item at 3pm on a Monday and had a knock from the postman at 11am the following day, that's only 20 hours from order to having it in my hand. Secondly it took me less than 4 minutes to fit the device to my new A6 Avant 2.0 TDI Ultra. Thirdly I have just cracked 53.1 MPG on a short (2 junction) motorway run (which is up from a previous best of 47.2 after a long motorway stint), to see what the device was like and ensure there were no warning lights etc or general issues with running it. So far nothing has indicated that the engine is not happy running this device. Fourthly the performance has improved considerably and that's running on the default settings. All I can say is that for a first impression on service and performance CHIP Express has done exactly what it says on the tin, which in this day and age I find quite rare. I am really really impressed with both product and service... and I've not said that for sometime.
David from Coaley with a Audi A6 MK2 2.5 TDI 180 said: The chip arrived the next day and was an easy fit - great instructions. I wrote to you before buying as I was keen to improve economy… anyway, economy is around 38mpg, up from 31.8, so good news! The car pulls really well and changes up much sooner through the gears - perfect.
Ian from Manchester with a Audi A6 MK4 3.0 BiTDI 313 said: 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!!!
Geoff from Kidderminster with a Audi A6 MK3 3.0 TDI 240 said: I bought one of your chips for my A6 3.0 TDI Quattro. I am delighted so far with the difference, I only purchased it for the fuel economy. Urban has increased from 25 mpg to between 30 and 31 mpg. On a motorway trip of 110 miles the car returned 45 mpg although this is usually late thirtys rather than in the fourtys. Thank you great product.
Joseph from Colwyn Bay with a Audi A6 MK4 3.0 TDI 245 said: Since fitting the CHIP Express device my 2013 Audi A6 3.0 Quattro is now how it should've come out of the factory - better throttle response, quicker, and with a significant improvement in fuel economy. I'm running the device in +2 and the results are excellent!
Neil from McMahons Point, Australia with a Audi A6 MK3 3.0 TDI 233 said: Wanted to thank you for your great service, speedy delivery to Australia and simple easy to understand installation instructions. I fitted the chip to my Audi A6 3.0 TDI Quattro last week and what a difference. Much more responsive, smooth and lightening fast now off the mark. Having done 700klms with the chip is looks as though I have reduced fuel consumption by about 10%. Great work, by the way, my friend bought your unit for his Audi TT 2.0 TDI, wow, what a difference as well!
Dejan from Ivanic Grad, Croatia with a Audi A6 3.0 BITDI 313 said: I have had this chip installed for almost 2 years on my Audi A6 (C7) 3.0L BITDI and have covered approx 80 000km since. The additional power has turned this into a top purchase! I have since bought a chip for my Vivaro 2.0 CDTI van, this was mainly because I put 17" wheels with 225/55 tires, so van was dead on the road without the additional power of the chip. Thanks from a more then happy customer!

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.”

“As do many, I took the 'if it sounds too good to be true, it probably is' approach to performance chips. But CHIP Express were recommended by an impeccable source who had had experience with their product on my model of car - a Citroën C6 with the 2.7 HDi twin turbo diesel. Following a first rate response to a query, the product has delivered in spades. Ten days and more than 1000 miles of mixed town, country, low and high speed driving later I am certainly getting more than 10% more from a gallon, and probably 15%, and the performance is markedly better. Low speed response is immediate and has eradicated what I took to be baked-in lag in a big automatic turbo diesel, and mid-range acceleration is silky smooth, including up inclines. A very good car has been turned into the excellent car I had hoped for all along.”

“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!”

Ford Kuga MK2 2.0 TDCi 163

“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.”

“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!”
