My ad blue injector was leaking on my 2015 Passt TDI. While they had it in the shop for that repair I had them do an oil/filter change also. When I got the car back it went through a quart of oil in 75 mile. I thought that they shorted me a quart with the change so back to the VW dealership I went. I watched them top it off with another quart of oil, after a fifty mile drive I was again down another quart. Prior to having this service I went 10K miles between oil changes and never had to add an ounce of oil. I contacted the dealership and the appointment guy was going to have a service representative call me back...I'm still waiting. BTW no oil on ground were vehicle was parked and none that I can see on the under engine protector blanket. I think it must be the new ad blue injector as there is oil visible around where the mating parts a press together. Any ideas or similar experiences. Ted...still waiting for the phone to ring.
