How much does the 2.0 TFSI take?
It is a turbocharged petrol with genuine headroom, which is why so many owners go beyond Stage 1. Stage 1 works with standard hardware.
Why so much Stage 2 work?
Because a large share of these cars arrive with intake, exhaust or intercooler modifications already fitted. If standard, Stage 1 applies.
Does it affect the quattro system?
No. The work is done on the engine ECU and does not alter the operation of the all-wheel-drive system.
