What 2015 Audi A4 Allroad owners say
Engine & cooling
Tl* the contact owns a 2015 Audi A4. Approximately one week after the vehicle had been serviced for NHTSA campaign number: 17V002000 (engine and engine cooling), a failure occurred. While the contact was parking the vehicle at 1 MPH, the backup sensor failed and the backup warning system failed to alert the contact of any objects behind the vehicle. The vehicle was taken to Audi of huntington (363 e jericho turnpike, huntington station, ny 11746) where it was diagnosed that the sensor wire had been cut. The vehicle was not repaired. The vehicle was taken to an independent mechanic who stated that the two wires were not connected and that the wires seemed "fragile". The vehicle was not repaired. The manufacturer was made aware of the failure and stated that they believed the dealer's statement about the wire being cut. The approximate failure mileage was 24,000. Updated 10/17/17
Audi safety recall 19n4-electric (after run) coolant pump. I have been waiting now about 6 months for a new pump to be available from Audi to replace the defective cooling pump, that is to cool the turbocharger after the engine is turned off. I was told, in writing and over the phone by Audi, that this replacement would be done by the end of 2018. Today when I called Audi they will only say it is to be completed by the end of 2019. Not having the after run pump properly cooling the turbocharger can cause damage to the turbocharger and that can be very costly to repair. Also, if I want to sell or trade in this car now, with out the replacement pump, the value of the car is worth less and I will loose money due to this issue. What can be done to get this pump replaced as Audi said they would originally?
Transmission & drivetrain
Tl* the contact owns a 2015 Audi A4. While the vehicle was stationary in the reverse position, it rolled forward. Audi of north scottsdale in scottsdale, arizona was made aware of the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 13,500. The VIN was not available.
S times now, the vehicle intermittanly fails to move when placed in gear, reverse or drive. Additionally, while underway, transmission "bucks" and in some instances, accelerates rapidly with miminal accleration at accelrator pedal. I have a video of the latest incident but am unable to upload it to your site.

I received a recall notice (19n4) and as a first step I'm advised to have an Audi dealer disconnect the coolant pump immediately to avoid a fire. I live 5 hours from the nearest Audi dealership but have a local shop that works on german made cars including the Audi. However, Audi refuses to provide instructions to the local shop to disconnect the coolant pump and avoid a fire. However, when I call my dealer they can't get me in on the day I'll be in the area. So, I'm told it's important but given no remedy to avoid a fire. Basically, Audi sent out the recall notice to cover their butts and really have no interest to resolve the problem. With the fuel economy fiasco and their lack of concern over safety recalls - maybe they should be barred from even selling cars in the U.S.a
