2017 A4 B9 premium plus model, AWD, 2.0T. I have had an Audi dealership service my car for all major service intervals outside of oil change, not only at recommended intervals but even early. 3 years ago I had my 40K mile service done at 35K miles. Spark plugs were replaced by Audi Hawthorne in Westchester county, NY. One week ago, at 49K miles (well before the 6 years or 60K miles Audi says their spark plugs will last) my engine seized while driving and was misfiring. This caused an engine shut down WHILE THE CAR WAS IN MOTION on the highway. I was able to restart and make it off the highway where the car seized again. I had to then be towed 30 miles back home. Took it to my locally well known body shop that I have used for years for them to say: 1. My spark plugs were loose and installed incorrectly and 2. …
Symptom of low coolant in overflow reservoir; below minimum line. Pressure test concluded leak in thermostat/water pump part. Appears to be a rampant problem spanning over a decade and affecting multiple trims and redesigns (i.e B8/B9 redesign/updates). Safety put at risk for possible vehicle fire or high pressure damage for engine coolant/radiator. The problem was reproduced and confirmed at a local (non-audi dealership) repair shop. They stated that the low level of coolant was due to a small leak in the thermostat/water pump housing. The vehicle has not been inspected by the manufacturer, police, or insurance. It will soon be in the local Audi dealership for a second opinion and/or possible resolution. I received a warning indicator on the dash and written pop up message on the dash board that indicated low coolant reservoir level. …
Air bags
I went to Audi Fort Worth (116 University Dr, Fort Worth, TX 76107) to fix my PODS recall currently on my Audi A4. After a day of servicing my vehicle for the recall the dealership handed me back my vehicle in the condition attached in the photo. You can see the huge gap in the seat which is a safety hazard considering there is high voltage wires in the seat and they just left it exposed with a considerable gap. They refused to reassemble my seat so I am unsure if my airbag sensors even work now, it has been a week of waiting and my VIN still shows that it has a recall even though the service was completed a week ago. I asked for a service ticket of he work preformed but Audi Fort Worth refused to provide me one. I went in for the recall service on 1/24/2021. Is there any way we can remove my VIN from this recall list since the service was completed? …
Our 2017 A4 suddenly had the passenger airbag warning light illuminate while driving. In addition a different warning stated "safety system malfunction." We took the car to the dealer. They saw that there was a code in the computer but said that this could be "because a wire moved." They claimed it was "fixed" by "restarting" the car.They did no repair despite our protests, and told us to bring it back if it happened again. The next time we drove the car it happened again. We returned to the dealer. They stated the following (1) there is nothing wrong with the car and we should ignore the random intermittent safety light and continue driving; (2) that "probably you won't have a crash during the malfunction, so it should be OK" and "Audi engineering won't pay to fix this under your warranty because "sometimes your seat heater can trigger this warning for no reason if you don't use the …

Engine light on Dealership found a rodent nest in the engine space in the car. Dealership considers that fluids used to coat Audi engine wiring attract rodents. Dealership considers this to be a health and safety issue. Dealership considers it essential to replace the Audi air filter. Dealership is checking wires to assess any gnawed damage. I need the engine to be power-washed and the nest area treated w/bleaching agents. I do not have the total estimate on this but it will be greater than $1,000.
