    It is listed as Instrument cluster malfunction with a couple lights on like Brake, ABS, steering wheel with exclamation point next to it. Often when I’m driving the screen in front of me that tells me my speed will go extremely dark to the point you can barely read what it says on it. I have not taken it to a dealership or service place yet but this is part of a recall that my car does not qualify for. One day it just started in January and despite efforts to reset it, has…

    On startup, the instrument cluster (Audi Virtual Cockpit) takes an abnormally long time to illuminate. When it does come on, the check engine light and multiple other warning indicators are illuminated.

    My independent repair shop has just diagnosed a coolant leak weeping from the vacuum line connection at the water pump; they referred to this problem as “coolant migration”. As documented extensively by Audi in Technical Service Bulletin 19-23-45 (2070349/2), this indicates an internal seal failure of the water pump, causing pressurized engine coolant to migrate directly into the vehicle’s vacuum system. While I understand that my vehicle is technically past its 4-year…

    My rear backup sensors have fallen out of my vehicle and the dealership wants to charge me $200.00 to diagnose the problem. All they need to do is reattach the sensors which were originally put on the vehicle with double sided adhesive tape which is a poor design. I cannot afford this $200.00. This is a big safety concern because I rely on those sensors when backing up. Can you help me?

    I am submitting this complaint regarding a safety-related recall on my Audi Q7 involving the alternator. The wording of the recall is significantly underplayed, written off as an emissions issues. When in reality this is a life threatening flaw in the alternator. It is highly concerning that Audi isn’t being transparent with people who are driving these cars and risking their lives while doing so. This is not simply emissions, in reality, the car can totally malfunction…
