5 times in the last 6 months the "glow plug" indicator light has come on and the vehicle experienced a loss of power. twice the car completely broke down, twice audi could not replicate the error code, the last time this happened i had just picked up the car from audi after it was repaired. the glow plug light came on and it went into "limp mode" where i experienced a loss of power as i was getting on the freeway, almost got hit as i couldn't accelerate past 35 mph.
Water pump leaks because of pcv valve failure
My vehicle completely shut down while i was driving it 60 mph behind a semi truck and between two cement barriers. i have it on video, it is one of my problems i had with my car to say the least. it happened once more while i was not moving, had it in the audi dealer for the second time. after i brought it home, it wouldn't shut down. i also have that on video. the videos are too large to upload, but everyone that drives an audi should see these. i am glad i am alive to tell my story.
After buying my new 2015 audi q7 on 9/27/14, i started experiencing hesitations when pulling out into traffic from dead stops. the very first time it happened i was in the median of a 4-lane highway waiting to turn left into traffic. i pressed the accelerator it started into the lane of traffic then stopped. i sat there for about 2-3 seconds before it took off. i expected to get hit. it wasn't the gas nor me. i have been driving for 38 years and driven over 20 vehicles and have never experienced this before. it continues to happen randomly and always unexpectedly sometimes 1 time a week sometimes 3 times a week. the hesitation is as much as 3-4 seconds. on 4/18/15 i brought it in to audi of new orleans. they called stating that they could not duplicate the problem and to come pick it up. i picked it up right at closing. upon leaving the dealership, i stopped to wait for traffic, proceeded to make my right turn, and it happened. on 5/25/15 i brought it to audi of baton rouge, which is where i bought it. they called me on 5/29/15 and told me: that they could not duplicate what i was experiencing; that the technician knew what i was talking about, but that is just the way the q7s are; and that the technician wanted to ride around with me when i come to pick it up. that afternoon and i drove around with the technician first in another q7 then in my q7. i could not reproduce it with either car. however, the technician did tell me that he knew what i was experiencing and that that is just how the q7s are and that the reason is because when i press the accelerator the computer takes control and decides if it will give me the power i need to proceed. i believe that no car should hesitate and put people in jeopardy by not giving the engine the gas it needs to perform as it should. i also feel that audi should make all drivers and future drivers of q7s aware of its behavior. ...updated 10/01/15*bf updated 12/05/2017*cn
