Audi A6 Diesel Chip Tuning Boxes

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.

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!

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.

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.

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!

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!!!
