I own a 2015 S4 DSG (31k mi) and recently purchased a 20k mi 2017 S5 DSG for my wife. The new car doesnt seem to have the same power as the S4 despite identical engine/trans/ sport dif.
The new car had the thermostat and water pump replaced at Audi dealer 4 weeks before i purchased the car. I'm aware that if the reassembly isnt done correctly there have been reported problems with low boost pressure...loss of prerformance.
I dont have access to diagnostic equip so looking for feedback on what i can check and how to go about it. Thx.
