GTI 337/20th Anniversary :: Overheating - All Dash Lights Randomly Keep Coming Up
Aug 22, 2015
So just for a little bit of a background, I have an Imola 20th with 165k miles on it lowered on B&G's, stage II+ unitronic w/ Franken turbo setup.
I've been running into some issues with the ride as of late, well, more than usual, and I can't seem to figure any of it out. First, the car kept overheating even when it wasn't warm outside after driving for only about 10-15mins. Took it to the shop, and they said that the fan & fan motor died on me and so they replaced that and the blower motor resistor, but then a month later I was back at the shop getting the fan replaced again. A month later, I was at another shop getting the fan switched, and not even two months later I was back at the original shop having the fan swapped out yet again because the previous one died. It's been a couple weeks now since the last fan being switched out and I'm starting to see some overheating issues yet again when the A/C isn't turned on and blasting. That's problem number 1.
Problem 2 would be all of the dash lights that randomly keep coming up; the traction control and ABS lights have been on for about three months now. Just last week the dash light for the airbag came on, and then today the light stays on for the door saying that it's open but the interior lights don't stay on like what's typical seen when the door is open. Also, every now and then when I start the car up the brake light will flash/beep a couple times then stay lit the whole time I'm driving around, but when I turn the car off then turn it back on again the brake light isn't lit...the airbag, ABS, traction, and door lights are still lit. I plugged a reader up to it, and no codes are showing and everything says it's checked out. Not to mention, the car has been idling real funny lately, usually sitting at 800rpm's then randomly dropped to around 400 to where the car almost dies off then it just shoots right back up.

Was driving home yesterday from work and the dash light up saying the car was overheating. Was too dark last night to look at everything so this morning I checked all the fluids and everything was OK.
Drove around the block a few times and noticed when starting the car the thermostat said normal temperature (straight up) even though it was cold, then climbed into the redzone, dropped to zero, then shot back up into the red. the upper radiator hose is hot so fluid is flowing.
Thoughts are bad water pump, thermostat, or blown head gasket after going though my repair book. Not sure how to check any of these. Also ran VAG and nothing came up.

I have a 2000 Chevy Silverado pickup, V8, A/C, 105,000 miles, which drives like a top.
However, about a year ago, the TWO brake lights on the dash started coming on together, randomly. Sometimes the lights came on right after I started the first time, other times, they came on later in a trip after the truck warmed up.
The brakes worked perfectly, as far as I could tell. I took the pickup to the dealer, left it 2 days, and they checked the brakes, belts, tried everything (they said) including trying to get error codes on the computer. Trouble is, the lights had mysteriously gone out and refused to come back on.
A few days later, they came back on for me!! I could turn the truck off, wait a few moments, restart it, and the lights would go off, say, 80% of the time. Only to come back on later. So, I took it to a local Goodyear Tire store (while getting new tires) and they saw the lights, did a diagnosis on a computer, and got NO codes.
Now, I'm worried very much - you see, the brakes on this truck have never been changed! I've had them checked many times, always with the answer that they are still in great shape - last time, they had 30% left! I waited until the lights were ON, and drove all the way to the dealer; parked the truck running; and waited until a technician could come out and do the computer test. NO codes.
Now, I have noticed a possible pattern: when the weather is hot, as it has been most of last year here, the lights come on; when it's cold, as it's been lately, the do NOT come on. Just today, the weather warmed up into the 70s and, zap, the lights came on today.

I am having a weird overheating issue, it usually happens when the car is idling, and cools down when i start to drive the car again. What could be causing this problem.

My car alarm keeps going off randomly. It doesn't matter if I lock it or not. The car alarm just goes off and quits on its own. What might be wrong?

I just recently put a new battery in and I was wondering if thats why my car alarm goes off sometimes? I've also noticed about a week ago in my gauge cluster that the sign for the door being opened was on and then it turned off and then flicker on and off for about 30 sec ? So I think that has to do with the alarm but my question is how do I fix this problem???

So I noticed one day when I was standing outside of my car right after I had turned it off that I could hear the coolant bubbling some. I had just recently flushed the coolant, put on a new water pump, thermostat, and put in a new reservoir with a new cap so I figured it was just some air in the system because there was air in the top radiator hose. So I just worked the air out and thought that was it. The next time I drove my car it did it again and there was no pressure release when I took off the cap either. I ended up getting the head worked on (valve job and check the head for warping). Even after all of this my reservoir doesn't seem to build pressure and every time there also seems to be air in the top radiator hose. After the car is warm I can work coolant back in the hose and 5 minutes later theres air back in it. I've pretty much replaced everything with the cooling system besides the hoses within the last year so I don't know what it could possibly be.

So my 20th randomly won't start. It's happens about once a week or so. Most of the time when it happens the car cranks but doesn't start. Every once in awhile when I turn the key nothing happens at all and I have to keep trying and it'll crank and turn on. I also have no way to check for codes

So recently my car alarm on my GLI has been going off randomly while I'm at work and school. The alarm goes off for about 5 minutes and then stops. Tonight it's going off constantly and I don't want to wake up my neighbors and I need to sleep tonight. It's going off every 5 minutes even after I disarm the car. I've been searching up why it's going off online and haven't had any luck finding the source. Also after a few minutes of unlocking it the car locks itself and then the alarm sounds.

2 or 3 months ago i had to get my fuel pump changed due to my car dying randomly on the free way multiple times a week. The problem disappeared after changing the fuel pump, however it has started happening again recently. The car wont completely die but while going 60 mph or more, the car will suddenly lose all power and the gas pedal doesn't do anything for a couple seconds, then all power comes back and i have control of the car again. Why this is happening?

Car was running fine on friday when I left for detroit, it sat in my driveway all weekend, but on the way to work this morning I get a warning light to STOP and my temp gauge is right below 260. It took about 10 miles for the light to come on and the car does NOT overheat while idling. The car is only at 52k and I have not replaced the water pump/timing belt yet.

My brothers jetta is over heating constantly. The thermo switch on the radiator and controller box under the battery have been replaced. The fans dont come on till just before the red mark on the gauge. There are no water leaks, and we can hear gurgling when running the engine. How can we tell if the water pump is bad or not and where is the thermostat if it has one.

My engine light randomly popped up. Brought it to a shop, got scanned and cleared. A few days later, light came back on. From the scan, these two things popped up
17705 Pressure Drop between Turbo and Throttle Valve P1297
19537 Engine Temperature too Low P3081
cars a bmp 20th with 181km on it (around 111000 miles i think lol)
Also, how could i tell if my car has an aftermarket LSD, cause the PO claimed to have put in a quaife LSD. also, how could i tell if its chipped other than scanning it?

I replace my timing belt and water pump and my engine is now over heating. I notice it's only over heats when the ac is running and the engine is idling. When I start to drive the engine temp goes down.

Ive been having two issues with my GLI lately, last week while driving on the parkway my car just randomly lost acceleration, no lights came on but the gas peddle was unresponsive. I was able to restart it while coasting and thought nothing of it. Then it kept doing it. It was raining that night but ive never had an issue before. Other times it dies it is sunny out. The second issue is sometimes when I hit over 10lbs of boost the car will start to misfire and run like crap. No CEL's come on the dash but if we scan it with VAGCOM it says theres misfires happening, obviously. Already did a smoke test and there are no vacuum leaks.

My sister has a 2004 gli 1.8t with 65k. The temperature gauge says its overheating, the cel is on, but the car appears to run fine, the fluid levels are appear to be fine, and you cant see any leaks. Her fiance thinks its water pump issues...

My Jetta has been throwing this code on and off for over a year now. It used to only come on when it was really cold with wet roads. Now the code will randomly come on in any weather. I usually just clear it but it's coming on to often now. I don't notice any performance issues or gas mileage problems.
Scan shows : Trouble Code - P0420 Catalyst System Efficiency Below Threshold (Bank 1)
I've been reading and apparently 1.8t engines only have One bank? I'm assuming this the the front 02 sensor throwing this but not sure?
I have an aftermarket exhaust/high flow cat. Apparently this can be caused by a high flow after market catalytic converter and one solution is to use a test pipe or spacer to move the rear O2 sensor further from the exhaust gas flow. But I'm not sure this is the issue since I think it's my front sensor throwing the code? That's not by the Cat is it? I just don't want to have the sensor replaced to have the code still come up.

I have an '02 337 GTI, Chipped but the previous owner don't know what chip is installed
Anyways, lately if I'm just cruising around the city in 5th, or on the highway, the engine will shut off completely. Electrical still on, battery light and all that jazz does not come on unless the RPMs go all the way down, then I have to actually start the car up again. Takes alot longer to crank afterwards.
Sometimes I will be driving and it happens, but I keep my foot down on the throttle, and just wait and engine will kick back in hard as hell!

I just drove the GLI from pa to myrtle beach for vacation. On the way back I noticed the temp was steadily rising while idling at a red light then at a gas station. Coolant level is fine. Thermostat, water pump, thermostat, and both temp sensors were recently replaced in the last two months.
So I know none of those things are a variable. Both fans never come on. I tried turning on the ac to get them to come on. But nothing. I read as much as I could on forums to find a solution but none applied to my specific problem.
Car is completely stock besides p flow intake. Has 153000 miles I'm pretty sure everything involving fan is original.

My 2001 Town and Country runs great but randomly dings most commonly on longer trips. For example this morning I drove 130 miles it did not ding until I had driven 40 miles and then it dinged again at 50, 55 and it gets increasingly closer together until by the time I got home it was dinging 15 or 20 times a minute. It is at random intervals. It has dinged non-stop. It does not seem to matter how fast I am going. There are no lights on, on the dash. It does not appear to be over heating. It doesn't seem to matter if I am going up hill or down hill or driving level. It doesn't matter how much fuel I have. As it increases in frequency sometimes it will ding once while other times it will ding 2 or 3 times quickly. I am trying monitor different variables but it feels random except it typically starts around 40 to 50 miles into a trip but it has started dinging immediately when I first started it for the day. Sometimes it doesn't happen at all on long trip or it only happens once or twice but never progresses in frequency. I recently drove 250 miles and it only dinged once at about 230 miles and not again.
