Audi A4 Water pump and Thermostat failure. VW/ Audi USA had a recall on this issue for several models including the Audi A4 models thru 2016. My car was built in 2016 with model year 2017 and according to the recall my car did not qualify. Since then there has been several Class Action Lawsuits for this same issue. I was fortunate I discovered the leak while the car was parked in my garage and wasn't on the freeway. It seems that VW/Audi USA hasn't corrected this issue leaving many people in danger of a possible breakdown and a premature costly repair. In addition, I was denied the Class Action Lawsuit extended warranty by 3 months. So this premature costly repair was on me. Thank you for all you do to keep us safe.

Every time I start the car, a message comes on saying that the passenger airbag is off even when I have an occupant next to me. I spoke with the dealer and he told me that this recall was claimed and fixed in 2022 in Texas by the previous owner but I replied that the problem continues and he told me that this was no longer an Audi problem. Furthermore, every time it accelerates over 40 miles per hour, a message about the driving system in malfunction appears and also the automatic on and off system at stops stops working and when I drive it at low speed there is no problem. I took it to Audi and they told me that they should change the turbo and I told them that the car only has 100,000 miles and why they should change a turbo that only has 100,000 miles of use and they told me that’s how it is

I experienced similar undesirable engine behavior on two occasions. Upon coming to a stop, the auto start/stop system stopped the engine. Shortly after, when attempting to drive away, the stop/start system attempted to start the engine, but failed; the starter briefly activated to turn over the engine, but the engine did not start and continue running. The car was left in the following condition: Engine off. Gear indicator showing "D". Accelerator pedal unresponsive. Regaining engine power required turning the car off, applying the brake pedal, turning the car on, and selecting "D" with the gear selector. This behavior occurred on two occasions on different days; once on 16 March 2024 and the first time within several days prior. Both occasions occurred before the engine was at full operating temperature, and while the car was on a slight uphill slope. Ambient temperatures were in the high 40's or 50's Fahrenheit. By luck, neither occasion resulted in an unsafe traffic condition.

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. The electrode at the top of the plug had broken off TWO SEPERATE SPARK PLUGS and fallen into the engine, causing scoring to the engine and #4 piston as well as blow-by during combustion. They said this had to be caused by a manufacturing defect PLUS incorrect install. they fixed what they could and recommended I take it to Audi. Audi is now saying I need a whole new engine because of damage to piston 4, and not saying they will cover the replacement cost of $21,500.Â

Start Stop system failures. Upon engine restarting, it stalls instead. This has happened on multiple occasions and the dealer response is to just turn it off every time you start the car. Causes dangerous situations due to inability to move car until full power cycle happens.

Random Engine Coolant Warning. Since purchase of vehicle mid-March 2022, I have randomly received engine coolant warnings on the dashboard. Visual checks of the coolant reservoir reveal no issues. Internet search of issue reveals a number of other owners have had the same problem. Issue has occurred at all speeds and temperature conditions.

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. No OBD codes were collected by the independent service shop. They said that non were being displayed or read besides what was displayed on the dash.
