My coolant pump went out and overheated the car. The coolant leaked out. My car only has 60k miles on it. Audi recently recalled coolant pumps for this very reason on the a4, a5, a6 but havent made the recall for the s class. Please be advised this is a serious issue and placed me and family in harms way.

At about 49k miles the car would sometimes lurch backwards when in reverse or going from reverse to park. Took into mechanic. No diagnostic codes showed up. Around 60k miles the car overheated. Audi stated it needed a new thermostat which was around $1000. Drove the car across country from ca to co. Around 62k miles car went into limp mode and would not get out of 1st or 2nd gear. "gearbox malfunction" warning came on. Stated not to go into reverse. Drove home slowly. Next morning all warning lights were off. Took to mechanic. No problems could be found. May 2016 at 69k miles car went into limp mode again. Couldn't get rpms up. Reset codes using diagnostic tool. Drove from utah to co. Car went into limp mode probably 40 times on I-70. Car would lurch forward. Made it to dealer (prestige in lakewood, co). Mechatronics found to be faulty and car in need of entirely new transmission. Cost $12,000. Dealership 'paid' $8000. I paid $4000. This seems to be a common problem with this make/model/year.

At 57k miles got trans overheating warning while driving on back roads and car started to loose power. After a few secs went away. On way home same thing happened and was able to limp to dealer. Dealer diagnosed w/ bad mechatronics unit which appears to be common problem w/ early b8 dsg transmissions.

I am writing to complain about a design flaw that has been identified in the waterpump used in the 2010 audi s4 3.0t. Several owners have experienced a waterpump failure which results in the vehicle overheating and partial or full loss of power steering. Owners who have experienced failure have had their 'black plastic' waterpumps replaced with a revised 'aluminum waterpump'. Several owners have complained about this issue on various enthusiast forums, but the manufacturer has failed to acknowledge the problem and issue a recall. It is evident that the waterpump is a ticking time bomb that needs to be replaced so individuals are not 1) left stranded on the side of the road, 2) subject to an automobile accident due to lack of power steering, or 3) at risk due to an overheating vehicle. I personally have not experienced the failure on my vehicle, but I am submitting this complaint in hopes that the federal safety agency will work with audi to issue a prompt recall for all affected owners. I do have the old revision of the waterpump ('black plastic') on my vehicle and I am worried that I may eventually experience a failure. The following are some posts on various enthusiast boards that highlight the issue: http://www.audizine.com/forum/showthread.php/382525-another-waterpump-bites-it...?highlight=waterpump http://www.audizine.com/forum/showthread.php/317505-b8-s4-water-pump-failure?highlight=waterpump http://www.audizine.com/forum/showthread.php/352343-problems-so-far...-today-the-water-pump-blew?highlight=waterpump http://www.audizine.com/forum/showthread.php/349318-my-coolant-broke!!?highlight=waterpump http://forums.audiworld.com/showthread.php?t=2789310&highlight=waterpump http://forums.audiworld.com/showthread.php?t=2789742&highlight=waterpump http://forums.audiworld.com/showthread.php?t=2774524&highlight=waterpump http://forums.audiworld.com/showthread.php?t=2773666&highlight=waterpump.

The car was purchased on may of 2007. The cars instrument panel was working fine when purchased. All the cars critical information is displayed on the panel. A month after purchased I noticed that the panel intermittently fails. The car was running low on coolant but since I could not read the deploy I had no idea until the car overheated and the water pump blew. The repair alone cost me $800.00. Mechanic stated that the instrument cluster should have displayed that the coolant was low. So I also believe this would be dangerous because all warning information is displayed on the cluster; brakes, temperature and oil.

Vehicle is experiencing radiator coolant leakage into engine oil. This is causing accelerated wear of components lubricated by the engine oil. Unless corrected, this contamination will lead to failure of the motor. The vehicle was inspected and tested by an audi service center with no cause identified or solution proposed. Audi of america is not taking any action to address this problem.

(1) events leading up to the failure: none--I've been experiencing a coolant leak since day one. Only recently has it gotten worse and now I see that there is water in my coolant. (2) failure and its consequences - coolant in oil causes premature damage of engine components (bearings, turbos). New engine costs exceed $15,000. New turbos costs exceed $5,000. This problem is posted all over audiworld.com. Multiple people have had the oil checked and determine that high levels of copper (caused by coolant) were in the oil and would result in near-term engine/turbo failure. (3) what was done to attempt to fix the problem: (a) coolant system checked three times by audi service at my cost and they have not been able to determine the problem. Costs so far exceed dollars with no fix in sight; (b) water-pump replaced ; (c) secondary water-pump replaced I am about to pay $2000 to get the head-gaskets replaced. Unfortunately this is a maybe fix since the problem cannot get diagnosed. Multiple people have posted on audiworld that they have had the same job completed with no benefits to the problem.

Coolant leaking into engine oil at undetermined location. No cause identified nor solution proposed. Coolant levels in oil high enough to lead to significantly premature engine failure. No recourse provided by audi of america. Engine replacement only option at present.
