I had to pay thousands of $ on a leased Q5 at 85km to replace a cylinder head. 5km over lease. Audi Canada only supported a portion of cost. I now have car back and the power steering is extremely tight and Service due light is on. Any connection between the two possible??

 

I would be taking it back to the dealer and point out there were no issues before hand. I don't see how they would be anyway related but the fact it was fine (assuming) when you dropped it off would suggest something happened in there possession.

 

if the car is less tan 4 years ago , it should be 100% warranted work

Audi is part of the Ontario auto dispute resolution organization. if the dealer does not meet your needs, go for free external binding arbitration

all car companies are member's except for BMW
