Today we have a 2017 Audi A4 1.4 TFSI in today for EPC light on and loss of power.
The owner was naturally worried that it could cost thousands to fix.
Booked in for investigation today and we found a turbo charger boost system performance too low fault code.
The car is not boosting when observing live diagnostic data.
A visual inspection of the turbo quickly revealed the fault to be the actuator has detached from the turbo causing no boost. This is due to the clip corroding and taking its exit!
So a new clip fitted, all within the standard investigation cost. The car now boosts perfectly and the owner is relieved. š
