Anyone experience the extreme cold temperatures this past holiday in Vermont and it's effect on your A-4?<br>I had the following occur:<br>-18F, the coolant warning light blinks with chime. Check manual it says low coolant or overheating engine. This is upon initial start so the engine is not overheating.<br>Try turn off engine and restart thinking it is computor gremlin, delays warning light for few seconds and reappears again.<br>Do it several times and check coolant. Drive for 2 minutes and try again. Still warning. Finally as temp gauge creeps into 1/4 warm range system warning light goes off.<br>Dutifully go to local Audi - rep says coolant sensor is stuck and not to worry as long as coolant is there and temp gauge is ok<br>Anybody had kave this experience? Is this a worry? Happen every morning when temps were sub-zero.<br>Almost like a warning NOT to drive untill warm.<br>Also when this cold all systems are slow to respond, in particular, that some "pump" made some barely audible whine until warmed. <p>Quattro and Michellin X+M Alpins handled ice, slush, snow and rain admirably.<br>Skiing was fair at best<br> <br>Skimants, 98.5/ 2.8Qspt-tip

I live in MD and I've had the same problem. I took the car to the dealer and they replaced the sensor after finding no coolant leak. One week after the sensor was replaced, same thing happens. I checked the coolant level, which was fine, and continued driving. When the temp reached normal, the blinking stopped.<p>I have the car at the dealer right now to hopefully repair this problem for good.<p>If they come up with a fix, I'll post it.<p><br>Mick<br>98 2.8qm

I did a trip from Idaho to Iowa just before Christmas and had to do several very cold starts during that cold snap, including a -20 F in Cheyenne, WY. I never had any warning lights or trouble starting my 97 1.8T. It did make some noise until driven. Kind of a higher-pitched squeak that went away immediately after I started driving. Asked my local dealer about the noise, he thought it might be a belt. The noise doesn't occur unless the car is left outside overnight in well below freezing temperatures, and it never corresponded to any noticeable change in driving performance. I drove over 3000 miles that week without any problems. My set of Yokohama Guardex snow tires performed great in snow near Jackson coming home. Now if I could just get all the other cars to get out of the way...<p>Terry T. 97 1.8TQM

I did notice that the LED lights in the Trip computer were real slow to change from one reading to the next until the car started to warm up.<br> Biggest problem is not being able to wash the car when it's around zero. : - )<p>Greg "S"

When I lived in Burlington back in 95-96 we had several -20F days. The car started a little slowly and the LEDs were very slow to come up. No problems with the coolant light though. <p>Chris<br>96 A4 2.8q at the time<p>to reply, remove anti-spam x

Mick, <br>Sounds like you and I have this problem. What was your build date on your unit. Mine was Nov. 1998.<br>Possibly there might be a commonality to check out with Audi. My next service isn't for another 3000 miles.<br>Post me if you come up with anything.<br>TIA<br>Skimants
