hello chaps, ive just sold my focus st3 and decided to buy somet with comfet and poke! ive bought a Audi a3 tfsi 2.0 quarto. ive bought from a family member and its stunning and immaculate. my only concern is it sounds like a tdi? is this common or do i need to get her checked out? she drives lovely and dont sound noisy when driving! just on tick over ? and any info on chipping these cars would be great. kelvin
