PLEASE READ...My "check engine" light came on, on my Audi A4 2.0 Turbo in August 2015, had it checked, was error code P0089, took it to an auto shop, they performed a diagnosis ($95.) was told it's "fuel pressure sensor". Had it fixed ($280.). In February engine light came back on, back to the shop, same error code, since under warranty they fixed it for free, replaced with new one. Yay! Come April, engine light comes on again, back to the shop, same error. Took car in on Friday April 22nd replaced again! Started car on Monday, light back on, called the shop was told to take it back to get replaced for a 3rd time!! Is this normal? Could there be something else wrong with it? Should I take my car to another auto shop?
