Not to worry they are easily and economically sorted, our customer Richard had a major leak and was very impressed with our help in resolving it:
"Not only did the tune perform the desired EGR delete from the computer system but I got the added benefit of improved performance and economy. The noticeably faster acceleration and improved torque at lower RPM was a revelation. The Skoda was no slug to begin with but this really changed the game and transformed my driving experience. What was really surprising and something I still don’t quite comprehend was that on top of increased performance I also gained about 5- 10% improved economy, this pushed my range on a tank of diesel from about 850km out to 950km. Awesome all around and highly recommended!" Richard Provo 04/09/2019
