Smelling of engine coolant. After driving for an hour, you can see steam coming from the hood but no leak.

2014 Audi A8 vehicle has 57534 miles on it, a well maintained vehicle by Audi dealerships. When passing a vehicle on a 2 lane hwy the performance seemed to be compromised. Heard a gurgling like sound. The epc light came on. Pulled vehicle over to a safe location and vehicle would not restart. Dealership diagnosed turbo's blown and engine contains metal causing total engine failure. Our concern is if the engine would have seized up when passing another vehicle there is a real possibility that an accident could occur. There are a few technical service bulletins concerning this turbo issue, one in February 2017 and a production solution to the oil supply lines came in may 2018. What about all the vehicles that are out there still on the roads not under warranty and owners have no idea this issue exists? it seems to be a problem with the 4. 0l engines. Turbo's. "audizine" website did a forum poll titled 4. 0tt blown turbo poll. There is also a issue with coolant leakage on the turbo's that can cause damage per technical service bulletin may 2017. I am hoping for a recall before an injury occurs.

While driving on a city street my car suddenly stopped (4 lane street -- 2 going, to coming). There was very heavy traffic and I could not move the car as it would not come back on, nor could I shift the car into neutral to push it out of the way. As a result, the car remained in the middle of the road, in heavy traffic, for about 2 hours until the tow truck arrived. The car was towed to the local dealer where it the dealter took 4 days to diagnose it with having coolant leaked into the engine wire harness and into the pcm where it shorted the pins. As a result the car was completely inoperable. This caused a very unsafe condition as the behind me suddenly had to break and just missed hitting my car. The car just shut down and would not restart or engage the neutral gear in order for me to get out of the middle of the road. This seems to be a common thing and something that should require Audi to address via a recall in order to replace the affected part(s) before something like this happens or require Audi to make appropriate repairs to those affected by this common and dangerous fault. This is a serious safety issue! dealer wants $11000 to repair it! what should I do?? loss of work and pay as car is stranded at Audi dealer! agony! embarrassment!.

There was very heavy traffic and I could not move the car as it would not come back on, nor could I shift the car into neutral to push it out of the way. As a result, the car remained in the middle of the road, in heavy traffic, for about three hours until the tow truck arrived.

I was accelerating onto the freeway on ramp when the engine cut off. I managed to pull over to the shoulder but the check engine light and the epc light came on. I had to be towed into the dealer. There was a "coolant valve leak. The coolant migrated through a harness to the ecm and to multiple connectors thoughout the engine harness". The worst part of this situation is the extremely dangerous position I could have been in. What if the car stopped while in the fast lane, or express lanes of the freeway? this is not the first complaint of this nature on this model of Audi. Please check into this as I am sure it will cause a fatality someday.
