Audi A4 Heat Turns Off Then Back on

08-22-201106:36 AM

and then my a/c volition randomly just shut off i call back its just the fan thats shutting off only either manner it just stops blowing. Pauses for ii sec and then starts again. There doesnt seem to exist any kind of trigger that will go far do this. Information technology just does it at random. The owners manual says that the fan will shut off during wot to requite u a bit more than power for acceleration. Only it will do it while at idle or cruising speed. I dont accept a need for wot so i havent tested that theory yet.

same here, once in a while though

08-22-201110:xl AM

My buddy's does the same too...Any fix for it?

Yous are low on freon. The ac detects it's depression and shuts off the compressor to avoid damage to the system.

Right solution:
Have the organization vacuumed out, checked for leaks, fixed if need exist, and refilled.

Cheap solution:
Go to your local autoparts, become ane of those freon cans with the hose and gauge, and top off the system. Read the instructions on the can very carefully and do not overfill it. ...this is a bandaid solution usually, eventually you will probably need to exercise the offset option.

Wouldn't it exercise it a lot more than oftentimes if that was the case? This happens to me like maybe one time every couple of months....and I live in Texas.

08-22-201112:21 PM

Hmmm, that is very interesting I accept been having the aforementioned issue. Eerie, what exactly practise you lot mean by vacuuming out the organisation? Simply a complete flush of the fluid?

08-22-201101:27 PM

mine does information technology too... although im sure ive seen information technology happen with the A/C off also, only I cant exist certain

its non vary ofttimes though, maybe 8 times in the iii years ive owned the car, it happened once while I had two of my buddies in the motorcar who are both Audi techs and they were both confused likewise, I dont remember its depression freon as mine still blows cold, simply ill cheque into information technology

If by "turns off" yous mean the compressor shuts off and the "ECON" light comes on information technology's a low freon situation.

My HVAC unit actually blips off and then comes back on (t fifty-fifty retains its settings) every and so oftentimes... And I don't know WTF that is. I'thousand guessing the unit itself is just going bad. I don't drive my B6 ofttimes and I kinda forgot information technology does that. Information technology happens at random and probably once every 2 hrs of driving.

Basically.

A store that does A/C work has a machine that pulls the sometime freon out and puts the system under a vacuum to see if your system leaks. If it holds the specified vacuum and so they merely refill it with fresh freon and send yous on your manner. (with a beak) If information technology shows signs of leaking they have to discover and fix it. A/C systems should not consume freon. If they exercise it'south from a leak somewhere.

I don't bulldoze my B6 often and I kinda forgot it does that. It happens at random and probably in one case every 2 hrs of driving.

Basically.

A shop that does A/C work has a machine that pulls the erstwhile freon out and puts the system under a vacuum to see if your organization leaks. If it holds the specified vacuum then they just refill information technology with fresh freon and transport you on your style. (with a bill) If it shows signs of leaking they have to detect and fix information technology. A/C systems should non consume freon. If they practice it'south from a leak somewhere.

Crawly, thank you for the info, thats what I thought. My situation is the same equally yours. It is almost similar it shorts out and simply flips dorsum on inside a second of turning off. It never goes to ECON it just shuts of and instantly turns dorsum on with the same settings every once in a while.

08-22-201104:12 PM

mine does it iv-5 times a year. i dont recollect it has to do annihilation with the frion since last time that it did was later on i filled information technology up with frion. Similar evo-ski said mine as well information technology never goes to ECON it just shuts of and instantly turns back on with the same settings every in one case in a while. it merely shuts of for 2 seconds. i idea was some type of safe mode or smth similar that since i go along information technology on all mean solar day hither in fla.

08-22-201106:52 PM

Check this! Had Ac and so ECON light so this

08-23-201106:55 PM

hmmm mine sounds a little dissimilar than yours

mine will be blowing a 5 bars (or level 5, what always yous call the fan speed) for instance, so become downward to 0 bars i bar at a time, stay off for a second, and so start climbing dorsum upward to what ever it was set at before

I usually have my climate command set to 60, so chances are the A/C pump is on most of the time

08-23-201107:47 PM

Well im lucky my father inlaw has all the equipment for the air-conditioning unit so ill endeavour the solution on sat and allow you guys know how it goes. but mine does like most r maxim. No econ lite only fan shuts off ii 2d pause then starts back up.

08-23-201109:57 PM

hey mine does this besides, tin can someone confirm if the fix worked for them ?

07-xi-201210:52 AM

Did anyone ever find a fix for this?

07-11-2012xi:02 AM

i merely refilled my freon the autozone mode and it hasnt done it, i call back. im sure its that stupid auto arrange matter. i wish that crap would not mess with my frickin settings

07-11-2012eleven:04 AM

This thread is very disruptive, are people talking virtually your HVAC fan shutting off (as in no air at all blowing out of vents) or Vents stop bravado common cold air (Air conditioning result)?
jai5, what is your outcome?

07-xi-2012xi:09 AM

Basically y'all are cruising along and so the whole matter stops and no air is coming out at all. The lights fifty-fifty blink off for a quarter 2d and then turn back on. The fan speed indicator reads 0 and and then it will one past i add bars to the fan speed window until it is back at what it was before it shut off. The whole thing happens in nearly two seconds.

07-11-2012xi:eighteen AM

I definitely don't have that effect.

Everything on the on the climate control stays on. But the A/C stops blowing cold air for a few seconds and then comes back on.

My major issue that I'one thousand trying to solve is that my machine randomly turns off (whole machine) with A/C on while in traffic on really hot days.

07-11-201211:36 AM

I ended up replacing most of the system so i dont know which part in particular actualy fixed it simply i know i did non replace any mechanical parts only the electronics and information technology worked great until i traded up for my a6 avant. Which go figure has an a/c compressor consequence. By the time im done i will have redone an unabridged a/c organization on a iii.0 just on seperate cars lol. Worst role is hither in sc its gettin close to being 9 yard degrees outside on a daily ground. Or atleast thats what it feels like with no air-conditioning and 4/65 a/c lol.
