hi, I recently bought a Bitdi. Usually having great experiences with audis as I own an Rs6. 2 days into driving it all of a sudden it jerked me, and the fuel consumption went to 40 liters( a diesel 💀) then it slowly went down to 13 liters. Which is still abnormal for a diesel as days before that I had 7-10 liter consumption. Engine runs perfectly 0 issues. I took it to the mechanic he said its fine which I know it isn't. I got him to turn off CEL and boom day later turns on again. Then I find out that the other mechanic who repaired it for me didn't proprely install Air filter pipe to the airbox( the front part where the grill is)
Perhaps this could he the reason for CEL and A bit increased fuel consumption now. As its 9-13 liters. 9 when idling. Am I gonna be fine after this is attached back normally and am I overworrying
