I've got a 2017 TDI 184 that is due an oil service. Booked it in at AUDI and they advise me there is a "recall" software update for the engine ECM. I asked if this is something I can opt out of, and they said no. I'm open to improvements, but something tells me it might be related to emissions and therefore compromise the car.
Will I get it back doing 10 miles less per gallon and lower power?
