How does the 2.0 TDI respond?
It is one of the most rewarding engines we work on: the gain in mid-range torque is immediately noticeable, particularly on an estate carrying weight.
What is the 1.4 TSI ACT?
It is the version with cylinder deactivation for economy. It appears in our catalogue and responds well to a measured map.
Does it affect the 4Drive system?
No. The work is done on the engine ECU and does not alter the operation of the all-wheel-drive system.
