Engine And Engine Cooling Problems of Audi A4 - part 1

The turbocharger wastegate actuator failed suddenly at highway speeds, causing loss of engine power and making it extremely difficult to maintain highway speeds. The warnings that suddenly appeared caused the cruise control to cease working as well. The dealership (Audi miami south by the collection) inspected the vehicle and confirmed the wastegate actuator seized, requiring a complete replacement of the turbocharger. The vehicle has 53,000 miles.

I leased a 2023 Audi A4 with 0 miles. At ~10,000 miles my car automatically shut down electronically I have photo evidence of this. This happened again recently at ~45,000 miles, I almost got into a severe car accident and possibly died. This happened on the highway driving in the left lane. I tried to remedy this situation before and was ignored by aud's service center. I am scared I can die on the road and am taking in the car for repeat service tomorrow.

Spark plug for damaged due to oil seeping into it. This could lead to overheating of engine or cylinders getting damaged potentially leading to vehicle malfunction when I drive. Audi inspected the part and recommended to reseal the top of the engine. There was a warning for check engine which led to identifying the problem.

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.

Engine oil consumption, timing chain. This is a massive problem among Audi vehicles across the board. Engine oil consumption is abnormal and if unnoticed leads to engine dying in the middle of the road which is dangerous and I’ve personally had this happen to me on multiple occasions. The engines timing chain goes bad and causes the entire engine to need to be replaced which consumers have to pay for out of pocket. Damage from timing chain, rough idle, sluggish engine performance, rattling, engine failure. There are large amounts of consumers experiencing the exact same issues. Something needs to be done it’s not safe at all and Audi should be held responsible and liable to fix these issues. The engines are deteriorating at an abnormal and accelerated rate.

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.

See attached document for complaint.

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.

Piston ring defect and blew from over oil consumption. All years from Audi A4 2012-2019 recall law suit but they did not include 2015 which all years and models have same piston ring manufacturer defect it blew on me while I was driving home . Lucky I was in neighborhood and not on highway very unsafe.

Heating/ cooling system is not functioning correctly, continues to get warning meage from car heating/coolant warning, and engine coolant is leaking out.

Turbo needs to be replaced after only 58,000 miles. This has been an issue causing recalls on Audi models in different years.

Since I bought this car in June 2023, I’ve had two instances where the presence feature malfunctioned when there was no danger of any accident. I’ve had one instance when all of the safety sensors illuminated at the same time while driving. Finally, this past Saturday, my car malfunctioned and died/ turned off while I was driving. It took a minute or so to get the car started. A malfunction notice illuminated. The area traffic is congested, so people honking at me but nobody hit me. Luckily, I was not on the freeway.

I purchased a 2024 Audi A4 with 20 miles as a birthday present for my son on 12/20/2023 for $45,028. 81 cash, plus traded my son’s 2012 BMW 328i with 22,000 miles and they applied $8,500. 00 credit. This is an atlanta, georgia Audi dealership. My son drove the car for one week and his salesman had an appointment set for him to bring his car back one week later to add Audi connect software to vehicle and my son’s phone. We took his car back to the dealership and they added the software and we left. My son told me several lights starting turning on in his dashboard but he could not take the car back that day because the dealership had closed as we were leaving the dealership. I called the salesman the next morning and he said to bring car back and they would check it. My son could not bring it back until 10 days later on 12/30/2023, because he was sick in bed. His apartment is about 20 mins from the dealership so when he returned his car had 100 miles from only driving the vehicle to and from the dealership those four trips. Oscar in service dept said he needed to leave the car over weekend and they would check it Tuesday 1/2/2024 since that was a holiday weekend, and oscar gave chris a loan car. Oscar texted my son on 1/3/2024 saying his car had a defective air bag module and that module was causing all the trouble lights to appear on his dashboard, and they could not fix it until 30 days because they had to order part from sweden. Oscar also said they had to keep the vehicle and it could not be driven until that part was fixed because of all the trouble lights in dash and he wanted to make sure the car would be ok when my son starts to drive it again. I don’t like the fact that the dealer has my son’s car we traded in and they have my full payment of the remaining balance after my trade in was applied to balance of car. Is this car a lemon and is it normal to buy a car only to have dealer keep it one week after Audi connect software was downloaded? thanks.

Vehicle was inspected at 50,000 miles by the dealer and report says that passenger side motor mount was leaking. They also said that the motor mount will deteriorate rapidly and will affect the safety of the vehicle.

Loss of power / turning onto oncoming traffic there was severe hesitation. Which caused the car to not move onto oncoming traffic quick enough causing both oncoming vehicles to maneuver around. Upon going to the mechanic he states I have oil in the engine from faulty piston rings which he states he has seen multiple times in these models.

The contact owns a 2019 Audi A4. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer and the contact was notified of an electrical failure within the vehicle. The electrical gauge, the surge charger, and the shift sensor had failed and needed to be replaced. The dealer also determined that the engine needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 104,096.

Car has 69,700 miles. All Audi suggested maintenance has been done. Synthetic oil changed every 5,000 miles (more frequently than Audi 10,000 mile recommendation). At 60,000 mile oil change, engine used 1 qt of oil. At 65,000 miles engine used 2 qts oil. At 69,500 mile oil change engine used 3. 5 qts of oil. Audi is not sure this is excessive oil use. Must perform oil consumption test at our expense. Really?!?! Audi solution is for us to pay $8,500 for new pistons and rings. From what I see online, this is a common problem, a manufacturer defect that Audi is unwilling to stand behind. Please share my complaint with Audi USA. Registered a complaint with them also.

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.  .

The vehicle at 13,xxx miles on the high ways, and during stop & go traffic; vehicle begins to tremble, transmission and floor shakes, rpms are higher than normal, abnormal noises coming from engine (screeching), jerking on acceleration on the first gears, rough idle, happens only on highways after 1hr of driving. Can drive over 40 min without any check engine light turning on. No codes come up, while clearly having issues. After a day of being off, car goes back to normal without those issues, just vibrations and pulsing on idle. -happens on texas highways where vehicle begins to have trouble with acceleration and transmission shakes yet no check engine or error messages appear. -problem has been shown to one Audi dealer while happening and another Audi dealer was able to reproduce the problem. They even noted how vehicle will do all the issues noted above while not providing any error codes or messages. - vehicle has been inspected but all they do is reset software and hand back keys. While issues are still prevalent. - no warning, no over heat or any codes appear on the vehicle. Issues started at 13,xxx miles. Only on long highway or stop and go traffic does it happens.

This Audi doesn’t have a dip stick that comes with the car. It burns 1-2 quarts of oil a month and doesn’t indicate when your car is low on oil. It’s a guessing game when the engine says put a quart of oil in and I needed 2 and a half quarts to be full. It’s such a saftey hazard I’m surprised Audi hasn’t recalled this engine. I spent over $1000 to have everything resealed and fixed because it just ceased one day due to not having enough oil.

So there have already been recalls on some Audis for oil consumption. I have a 2011 Audi A4 quattro and it goes through oil like crazy. It's ridiculous I believe it's because of faulty piston rings which led to faulty head gasket witch leads to the spark plugs, and coils.

No oil dip stick. The engine sucks a qt of oil every 2 weeks without leaks and due to the lack oem dip stick not in if you overfill your oil you’ll get bad spark plugs.

1) turbo, not because I'm looking to replace it 2) the car could stall when merging into highway or passing on the left lane 3) yes 4) no 5) yes, check engine light came on afterward check engine light came on after I tried to merge into a lane, while I was stepping on the gas peddle hard there was no acceleration. While the car did not stall, but it was not moving fast enough to provide the distance I need to be safe from the car behind me.

Vehicle has horrible oil consumption due to piston rings being defective upon manufacture. Vehicle will have slew of problems, including stopping in the middle of the street, risking the lives of everyone in the car. Audi dealer knows of the problem with the model from this year (b8) and they refuse to fix.

Overheating in traffic replaced water pump, gasket. Radiator , fan control module, thermostat, and hoses. Happens every summer!!!!! no fluid leakage. Could this be the same problem as the 2013 model recall.

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.

Came to a stop sign car completely cut off and wouldn’t start again.
