Golf IV R32 :: Slight Overheating / Low Speed Fan Is Coming On
May 8, 2013
So yesterday in traffic my R went up 1 tick on the temp gauge while in traffic. It took about 30 minutes in traffic for it to go up that one tick. I know that there is some test you can do to check if the low speed fan is coming on. What is that test?
This morning in traffic for 45 minutes and no overheating of any kind, temp didn't move from full vertical... That being said, when i got to my office, I popped the hood and tossed the AC on while parked, only 1 fan (pass side) was running, aren't they both supposed to be going with the AC on?

My R has 133,000 miles and is overheating at speed. It will cool down at idle. Both fans are working. The water pump was replaced at 105,000 and I replaced both fans at 95,000 miles. The dash temp gauge goes almost to the red, but not all the way. It gets hot enough to shut off the A/C compressor.
Based on the collective wisdom of this forum, does this is a failing water pump, or a partially opening thermostat? This past winter it seemed to take longer for it to get warm. I'm leaning to thermostat.

I get a whine when I'm driving hard under low speeds and accelerating (only when really aggressive). Is this cause for concern? Haldex whine I'm assuming?

I have a 2010 with about 166k miles. I am getting a slight hesitation at slight acceleration or constant speed. It does not matter if it's on highway or freeway speeds. Now I am not sure if this in junction with me changing the PCV valve, cleaning the EGR pipe, or cleaning the TB for carbon recently. It started happening a week after it though.

As the title says, car is overheating. Car gets to 190F within a couple miles drive. Temperature fluctuates between 190F and 225F.
Water pump was replaced ~2 months ago. Was not overheating prior. Temp reached 190F and stayed. Currently has the "black top" coolant temp sensor.
I noticed the coolant fans are not running after I turn the ignition off. This time of year they would usually be running after turning the engine off. If car is overheated and with AC off the fans do not run while engine is running.
I used the guide below to try diagnosing the cause: [URL] ....
Remember both fans should come on in slow speed any time the key is on and the AC is on - if the temperature is above about 32 F (0 C). Both fans run with key on and AC on
S180 (fuse 8, 30 amps, green plastic, above battery) must be good for slow speed operation.
Fuse and holder look good: no melting, no discoloration.
S164 (fuse 3, 40 amps, metal strip, above battery) must be good for fast speed operation.
fuse looks good: unbroken.
To ensure the AC circuits and the Fan Control Module has power check:
Fuse 5 on the cabin fuse panel.
Fuse 16 on the cabin fuse panel. When this fuse is blown the radiator fans will often run unexpectedly.
Fuse 25 on the cabin fuse panel.
All three fuses look good: unbroken
For the first test of the slow speed fans from the radiator thermoswitch have the key off.....Both fans should run in slow speed.
Passed test: both fans run slow
The second test is for the fast speed fans, key on, AC off.... Both fans should run in fast speed.
Passed test: both fans run fast
If the fans run in the tests above, then you should be good to go. No further tests are needed.
If you have been seeing high coolant temperatures and the fans have not been running, then you may need a new thermoswitch.

Picked up my MK6 GTI DSG last Saturday. I have noticed a slight shudder when braking and coming to a gentle stop. At first I thought it may be the brakes bedding in so I kept it over the weekend. By today there's still no change. Is it normal for DSG transmission stop like this? Because I have never driven DSG transmission.

A few weeks ago, I noticed a very slight noise coming from my shift boot. The noise wasn't a grinding or clanking noise; it was more of a noise that sounded like keys jingling or coins rattling (the best description I could come up with).
Anyways, it would only occur on acceleration. When the car is in neutral or shifting between gears, there is no noise. It lasts generally for about 3-5 miles, and then goes away. I haven't had any change or problems in shifting.
Not sure if something is loose in my boot, or if the linkage may be off, or if I should maybe change out the gear oil (since the noise goes away after the car is warmed up).

I have an 04 gti 1.8t and last night it started over heating. I pulled over and checked the coolant and the oil but everything looked good. I let it cool down and drove it home. When I popped the hood there was a little steam coming from the coolant overflow tank but I saw no leaking. I decided to vent the pressure off the system and then I got a little drip on the passenger side close to where the inter cooler is. I can't pinpoint the leak though.

Took delivery of my 2015 GTI a few weeks ago. Overall the car is great, but I have a feeling the tires that came with it just plain suck. They are Pirelli P7 Cinturato A/S. According to Tire Rack, these are grand touring tires?! Not exactly what I'd expect to be put on a GTI. Anyway, I've noticed that at almost exactly between 60mph-70mph there is a "whine" sound coming from them, also just the slightest vibration in the steering wheel. At every other speed they are relatively quiet and the wheel is absolutely dead solid, no vibration. Could these tires just be of relatively poor quality? Should I have them put on a balancing machine to see if everything checks out? I'm assuming these were balanced on a Road Force machine at the factory since that is the OEM for VW/Audi, but I'm not 100% sure obviously.

So I have a 2015 SE DSG. I'm getting the irritating popping noise, at no particular speed, coming from what sounds to be the middle/rear. It is lowered on H&R coilover, which I have checked over and over again to make sure everything is tight. It started about 500 miles ago, and the Coilovers have been on for about 6000 miles, the car just hit 7000 miles.

I purchased my .:R last summer with just over 100k miles on it. Two prior owners, car was fully stock and in great condition except for one thing:
Humming/vibration ("brrrrr" sound) coming from the back of the car when turning at a slow speed with the wheel fully cranked, e.g. moving out of a parking spot. It only occurs when moving, and with the wheel fully or almost fully turned in one direction.
The guy I purchased it from brought it to a local VW dealership when he noticed this and they (obviously) did not find anything wrong with the car, and blamed it on the tire wear.
So I changed all four tires. Still made the noise.
Haldex oil had been changed by the original owner but not by the second owner (who owned the car for two years prior to my purchase). So I had the Haldex oil changed and my mechanic said it was dirty AND at a low level, and might be the source of this problem. The noise did diminish for a bit, but it is still present.
So, I'm afraid my transmission or differential are fried from running on too little oil. It does not affect anything but it is definitely worrying me.

The engine light comes on and the wrench. Car doesn't get up to speed going up hills when this happens. One time it would not go over 30 without a whining noise. It's happened now 3 x's in 10 days.
First time the radiator cap was not on securely. Apparently that must have been from the shop because I have only had it for 10 weeks. Which is 2 weeks over the warranty and 2K miles over warranty also. Just my luck.
Doesn't happen every day, appears to be on hot days. When it's cool in the 50's or 60's I'm fine. First happened when it was high 90's. Then today its about 80.

My 2006 Azera has a most bizarre problem. I can drive the car just about any where I want to with no problem. However whenever I drive it at a very low speed it starts to overheat, and it overheats quickly. It is most notable when I drive up the hill to my house. It is a dirt road and is a very steep hill. I generall shift into 1st to climb the hill. To see if going into first caused the problem I tried the hill a couple of times leaving the car in automatic. One time it did not overheat and the second time it started to heat up a little but then cooled right down once I stopped the car.
The dealer told my wife there could be a bad connection on the battery and they tried tightening the connections and the second time they replaced a battery cable, which was not cheap, and how either of those could affect engine heat is beyond me. I am at times almost suspicious that perhaps I just have a temperature gauge that goes psycho every now and then, but it goes psycho consistently. I don't think it's a warped temp gauge. The dealer hasn't mentioned the thermostat as a possibility and I'm thinking of pulling it out and testing it myself.

I have a 96 honda civic that I can't seem to figure out why its overheating. I've changed the water pump, thermostat, radiator cap, and cleaned the system a number of times. It only seems to overheat when I'm on the free way and up to speed. When I get to my destination I see that the water overflow is full of water like to the top of the filler, so the water is being ejected out of the system. It also seems to have a lot of pressure in the system.

About a month ago, I noticed a slight 'thump thump' at speeds under 20 and started thinking either tire or wheel bearing. Turns didn't seem to change the sound/feel but it always smoothed out over 30 mph. I could not see anything visibly wrong with the tires other than the front pair needed to be replaced. Wear otherwise looked normal. But Monday night, I needed to pickup my laptop computer at work and my wife and her two dogs came along.
It was midnight when we left but for good measure, I felt around the tires and could feel nothing. Overcast, storms were predicted and were on the radar west of us. We walked the dogs; got the computer, and; Holly said she'd like a nightcap. So we went to a local bar and had a good time. Got back in the car, backed up less than 2 ft and 'poof' a cloud of white power flew from the passenger side, front tire:
As I was getting the tire off, a brief 'sprinkling' occurred...

I have a 1994 F-250 that we have changed the thermostat, radiator, water pump, cap, hoses, and installed a spring fan. New heads. Hot heat in the heater. It runs normal at highway speed for around 10 or 12 miles and gets hot. pull up and idle and the temp retracts. Even the block has been blown thru. What could possibly be the problem?

My '97 Honda Civic overheats when driven at high speed on the highway for more than an hour. I've changed the thermostat and the radiator fan, but it still does it.

I have a 2010 prius with about 245k miles on it. I have recently noticed slight vibrations at speed of 15-20 mph and or when letting off the accelerator. I also noticed it goes away at higher speeds. I don't feel these vibrations when on battery or when coasting down a hill. I did an oil and filter change in March. I am planning on changing the spark plugs soon. What might cause a prius to jerk or vibrate?

Ive had my new Phaeton just over three weeks and have ha to take it back to the dealer with a slight wheel wobble at high speed, I gather the geometry on these is quite complex and the alignment is usually done on all four wheels. Interestingly however the dealer diagnosis is for four new tyres, obviously this is under warranty, but it seems strange to have to fit four new tyres on a brand new car!

So when I shift "normal", e.g. just driving around, I notice a slight bump between 1st and 2nd and the other gears as I enter the gate. And it is good feedback that you're entering the gate. But when I am trying to clean out the injectors from a stop light , that bump between 1st and 2nd becomes a lot harder to push through when I try to do it fast. My old Jetta was not that way.

I have a 2007 Accent that I love but have a strange issue. I had both front wheel bearings replaced about four months ago. Recently (about the past three weeks) there has been a slight vibration at speed once I hit over 50 kph, which sounds/feels like an alignment/axle issue (almost like there is a flat tire type of sound) but there isn't any sway when I let go of the wheel and I had the front end inspected and they told me there are no loose parts.
I took it to a shop, and they said a wheel bearing needs to be replaced. So of course I took it back to the original shop and had them check it again for free - they said it isn't a wheel bearing but what it could be.
