colin123- the starting problem ended up being an electrical problem. The Transmission switch was getting intermittent power. It took a trip to the local shop but it was solved. I also had a problem with the engine slowly overheating. Brought it to the same shop and i was quoted a water pump, timing belt, thermostat, and other "goodies". Brought it to a specialist who charges dirt and did the job (just the thermostat) for 150. Find one of them haha

| I have a 2006 A6 and periodically get the parking brake malfunction message displayed along with a loud warning sound (which keeps repeating). This only happens when I am driving and the cruise control is engaged and has been in use for several hundred miles. I have taken it into service several times. They see the messages recorded in the log but have checked out the parking brake and there are no problems. If I turn off the cruise control then the warning message goes away. Service cannot find the cause of the problem. Has anyone had a similar problem? Does anyone have any suggestions? Could this be a problem with the cruise control? Or with the parking brake sensor? Or the computer? | |

| I own an Audi A6 2.0 TDI. Sometimes, (once a week or so), the engine revs by itself to 1500rpm without any reason. The gearbox is 7 speed auto. This may take from 10 to 20 mins. When you brake and slow down to almost a halt, the engine rpm drops to 1000 (not 900 which is the normal revs). Any idea what is wrong? | |

Replying to: erickpl (Sep 23, 2008 12:41 pm) Thank you for your response.......... Here goes.... Bought the car with 46k miles. Car has 48k miles and had the following problems: Hazard switch kept falling out of dash - replaced Right B-Pillar AC vent not blowing - replaced http://www.youtube.com/watch?v=MkG60oRDmmQ - that was the cold start noise I was hearing. That was the beginning of my woes. Initial dealer I bought it from, I will keep them unnamed at this point, stated they could not fix that problem because it did not trip a computer fault. Mind you, they reproduced that sound, even in my presence. Their conclusion - wait till the part breaks so they can replace it. 70mph on the highway and THAT part breaks, I can't say that would be a nice thought. None-the-less that is what they told me. Brought it back to that dealer at least 5 times when the noise was getting worse and more frequent, they told me the same thing. Frustration doesn't begin to describe my feelings at that time. Brought it to another dealer, they also could not trip any computer faults. Difference here? They told me they needed to keep the car overnight to reproduce the sound and single out the part that was causing the problem. They found a hole in the exhaust manifold(somewhere) which was caused by rust. Replaced that part which fixed THAT noise, total cost $2,000+ which would not have been covered by CPO, 2k more miles and I would have had to foot the bill. Now, with that fixed they heard another noise which was attributed to a worn timing chain tensioner? My car is on lifts, engine and tranny out. Can't imagine the cost of parts and labor on this. So far I am very pleased with this dealer as they are at least trying to fix the problem. Oh yeah, my bluetooth is working on/off. Every 10 or so connects I get a "telephone notes" screen on the MMI display and lose entire control over the telephone. I hope this dealer at least updates my MMI which would hopefully fix the issue. Suspension is VERY noise over rough roads. Car lurches in second gear at about 15mph when I ease of the accelerator. That car is beautiful, is very solid and is very stable at +60mph. If all of these issues are resolved and no other appear, I would be a very happy customer as this is my first venture into the 4 ring world. I am not trying to cause any wars or anything but, I have had 3 BMW's, 1 - 335i(52k miles), 1 328ci(82k miles sold), M5 (62k miles) with not 1 issue. |
