2.0 Tfsi hesitation whilst under Hard Acceleration
Recently a few days ago a problem started on my A4 2.0 Tfsi Quattro Manual Saloon Dynamik 11 Plate, when i accelerate hard in all gears when the revs start to get quite high you can feel abit of a judder/hesitation but it only happens when the Engine is warm, I am not sure what this problem is. I have only done 11,500 miles and i only have 1 modification which is a Revo Remap since about 5000 Miles, and i am not sure whether or not to take it back to Audi or not with the Remap, There is also a New Software Update available on my car which might override the Remap.
Also a few months ago i used to use Shell V Power but i got fed up with having to Travel to the Shell Garage as it is quite far away from my Home/Work, so i started to use Tesco 99 Momentum and i get told that it is a bad fuel for my car and you are far better off using Shell V Power and it could be the problem for your car, but i am not sure what it is, a couple of days ago i filled my tank full with Tesco 99 Momentum so i am going to use it all up and fill it full with V Power and give it a good blast and see if it Improves.
Please help me out,
