Basically my AC isn't cooling as much as it should..is it necessary when replacing the compressor to also replace the "dryer" and the other component which escapes me at the time...I think it's the "evaporator"
View 2 RepliesIs it possible to have work done on a 2002 Passat's A/C that isn't cooling very well. Can they add freon or whatever?
View 1 RepliesI need locating the aux cooling fan fuse location. Where could it be??
View 3 RepliesSo CEL came on a few weeks ago as it does here and there so got it scanned today and it said "cooling system too lean" could it just be the mods throwing the light. car is tuned so i thought cel wasn't suppose to come on and no mods to the cooling system beside cold air intake..
View 6 RepliesOne of my cooling fans will not shut off, I think it is the aux fan. Anyway it will fun till batt is dead either hot or cold .
View 2 RepliesI have a 2006 Passat 3.2 and a while back, I noticed that it would take the AC a very long time to cool, once it got temp down, it was fine. I checked low pressure and it is just perfect. I noticed, once car would cool down, and one gets to read light, after being stopped again, ac tends to get warmer. AC fan seems to be running fine and no errors on Computer. Miles 105,000
View 3 RepliesNot enough cooling in the B5.5 Passat wagon.
I had the freon checked and it seems to be fine, however it takes a long time for the cabin to cool of here in North Carolina. THe air coming out of the vents doesn't seem as cold as my older 1998 Passat. I used to have a silver sedan 1.8T and the a/c was temperature was ice cold and it got very cold after 20 seconds or so. It reminded me of GM cars.
My wagon is dark blue and beige leather interior which is probably why it takes longer to cool off. If you go for a short trip and the car has been out in the sun it would take at least 15 to 20 minutes to get comfortable. The compressor generally cycles off only once and then it stays on for the duration. My old sedan was the same way. I use the a/c on the rec mode which keep the air colder but still not quite as cold as some other models.
My MIL came on the other night so I brought it to the dealer today for diagnosis.
Per tech, "Found 1 DTC P2181 for cooling system malfunction, checked measuring values, found thermostat sticking open.
Recommendation is to replace thermostat with housing." I have 95K miles on the car, original owner...first time in a long time to have an issue.
The SA indicated the thermostat replacement. The tech indicated the thermostat is in the front of the engine which is hard to access.
Planning on doing a flush, but how do i bleed the air in the system after? is there a bleed bolt?
View 5 RepliesSo i let my car cool down for a minute after i drive it and today while it was cooling it would like bog down but it wouldnt die. Ive seen it while at a stop sign or stop light. Only while it was cooling down. It is HOT here so could that be the problem?
View 1 RepliesI have a 1997 no turbo Passat 2.0 6 cyl.Over the weekend one of the plastic pipes for the coolant system cracked and after the replacement I end up with the panel telling me that there is no coolant on the reservoir. How to bleed the air out of the system or if there is any bleeding valve for this purpose? And where is located?
View 1 RepliesI have an 06 Passat 2.0T, and last night whenever I shut off the car, the cooling fan is constantly running. I had to unplug the battery so it wouldn't drain it, and about 5 hours later, I hooked it up and it stays off. I also noticed when turning on the air conditioning, the smaller fan doesnt kick on. I'm lost and don't know where to start. Could it be a thermal switch or the whole fan assembly
View 19 Replies I've recently started popping up a random P2181 performance malfunction in cooling system.
It's so random and shows no signs of any other problems that I'm confused. Temp gets hot, stays exactly where it should be, 200. Never gets a tick hotter, or even close to above 200. Air works, heat works fine. No loss of power. It only seems to come on when I really put my foot down.
The MIL came on and I scanned for codes. First was P0118, Engine Coolant Temp Circuit High Input. Reset it and then received P1296 -Cooling System Malfunction. Temp gauge needle is positioned where it always is.
View 15 RepliesWent outside to start my '99 V6 and nothing! No interior lights, no door chime, no annoying ding ding with the key in the ignition. The car ran great yesterday but I noticed it sounded like the cooling fan was running long after the car was turned off in my garage.
I tried using a car starter/charger and charged it up for 3 hours - was reading a positive charge on the gauge- but it won't start. When I get ready to crank the car with the charger attached to it, the fan noise kicks in again but it isn't coming from the radiator fan- it sounds like it is coming from under the air intake for the air filter.
When I attempt to start the car,I can best describe the sound as a machine gun like cranking noise that lasts as long as I turn the key. I am hoping it isn't the starter. The battery is less than 2 years old with about 10k miles on it.
Have an '07 2.0T w/92K on it. Check eng light came on over the weekend. Performance is fine etc. Went to AutoZone just to find the general area of the the trouble code since there's no one with a VAG Com nearby. The code is as the title indicates. For the last 5 months the temp gauge has been moving 1-2 ticks to the left (cooler) of the normal 200 degrees, then it will go back to 200 etc. It previously has always stayed on 200 once it warmed up. Does this sound like a thermostat?
If it is, I'm wondering if I could save some money while they were in there to go ahead and change the TB as well? From what I've researched the thermostat is in same area. I was planning on doing the TB at around 100-110k so while it would be earlier than planned I'd do it if it meant saving a bit from the combo work.
So, over the past day and a half my beloved B6 has been putting me through the wringer... Sunday morning I fire it up, drive to church, turn the car off and everything is fine. Church is over, I drive home, turn the car off and my cooling fan keeps running... I go inside and check again in about 15 minutes hoping it had shut off after 2 minutes or so, but nope, still running. So, in order not to kill my battery, I disconnect it. I let it sit for a few hours and went back out hoping that leaving the battery disconnected would reset something, but as soon as terminal touched the lug, the fan kicked on again.
Now, for the electrical issues that have come with this problem... Whenever I hook the battery back up, a few things can (and usually do) happen. The steering and traction assists don't work, the parking brake malfunctions, the transmission shifts HARD (if feels like somebody is rear-ending me), occasionally the transmission just stays in 3rd gear, and all of the PRNDS emblems in the dash readout are highlighted as if they're all in gear at the same time. Now, cut the car off and back on a few times and most of these issues go away, but other times I've got to fight it a while and disconnect/reconnect the battery for everything to fix itself. I popped my scanner on it, because it's throwing a CEL as well, and aside from the P0304 misfire code (stupid intake valve crud...), I'm occasionally getting P0864 - TCM Communication Circuit Range/Performance. Not sure what's going on, but it seems like my car is self-destructing...
This code came up on my car, what it means or what part needs to be replaced.
008577 - Performance Malfunction in Cooling System
P2181 - 008 - Implausible Signal - MIL ON

Mighty afraid evaporator is leaking. Is it a much difficult to replace as all other vehicles? Does dash have to come out to fix?
View 3 RepliesKnow it's fairly common for AC air to smell moldy, due to moisture on the evaporator. What brand of disinfectant spray Volkswagen uses to spray into the cowl vents? I've heard that some manufacturers use Ultra Shield, and some sites say Lysol spray is okay, too. Just wondered if VW uses something else.
View 5 RepliesI have a 01 classic for 1yr My 01 looks new at 154000 miles lots of parts replaced before purchased and after I replaced 12 volt and inverter pump. Looks like evaporator core leak.
