Passat (B5) :: 2000 - No Boost While Driving On The Highway
Oct 27, 2012
So I was driving for 6 hours yesterday and about 3 hours in my boost completely cut out on the highway. I didn't get any CEL or EPC light or anything. I took a look under the hood and everything looks okay. I also thought maybe the turbo blew but it isn't smoking or anything. What it could be?? Or some way I can diagnose the problem?? I have a 6 hour drive back home and would like some boost! It is a 2000 Passat 1.8T ....

I've got a 2000 passat 1.8t (ATW) Tiptronic with a GIAC chip a trubo smart bov and a new performance boost gauge. I've got a problem. My gauge habitually indicates me that i peek to around 15psi to after drop to around 11 but if i drive my car to hard for to long or i get to around 180kph, my boost decreases instantaneously to 5 psi. After, the only way to regain my boost is to let the car cool down on idle for 2min an then turn it off for 2min.
After that, every thing comes back to normal. If I don't do that, the car wont regain boost. You can drive like a grand-mother for 45 min and put your foot down you'll still see the boost go up to 5psi and just stop increasing. It's like it set itself an other max boost limit. I though it could be some sort of a safe mode because the turbo is over heating (it's red hot). I thought a oil cooler could maybe resolve the problem but i don't want to spend 200buck on that if it doesn't do anything.

Driving down the highway today, my car just all of a sudden quit. I had it towed home, and checked the spark and fuel pump. It turns over fine, there's plenty of spark, and the fuel pump works great, but I don't think fuel is getting all the way to the engine. Could the fuel line be blocked or something? Maybe the injectors?

My car died while driving on the highway. The mechanic said it was the distributor, but also that the fuel pump wasn't working. When he replaced the distributor, the car works, no fuel pump problem. Does the fuel pump shut off when the engine dies or is this going to be another problem down the road? 2000 Chrysler Cirrus Lxi...

I have a 2000 Toyota Camry CE (2.2L/V4) w/ 130,000 miles on it. Just recently I have been experiencing a stalling issue after driving on the highway for 19 miles (or 20 minutes) at a speed greater than 65 mph. As soon as I exit and take my foot off the gas the car will stall as if I just turned the key in the off position. After I pull over, turn the key in the off position and wait a minute or two, the car start right up as if nothing happening. The idle seems to be ?normal?. The engine light does not come on when this happens.
If I feel the car may stall when still on the highway after slowing down, I can shift the car into neutral and hold the idle speed high enough to continue driving. However the car will eventually stall. But again and I restart it and be on my merry way without incident. I have try switching to high octane gas, but that did not work. If I disconnect the battery for a few hours the computer reboots itself and it will take a few more trips at high speeds for this issue to occur again. I have put in a fuel injector cleaner and cleaned the butterfly value (air intake). I own an Auto Xray code scanner; however it is not showing any error codes. What this issue may be?

Subie was driving fine...drove it on highway and went to park and NO reverse. At first, I couldn't shift into park either, but then I was able to shift in park. I can move the gear to reverse, but nothing happens (engine just revs and car wants to roll forward as it is on slight incline. Hubby checked trans fluid and it was a bit low, added fluid, but still no reverse.

Do I buy an engine or sell the car for parts? My son’s car overheated while driving down the hwy due to a radiator leak. After a first and second opinion, two separate mechanics told me the engine has no compression so basically was shot. The car was in good shape with 102k miles and everything worked. Internet surfing has some used engines with 80-100k miles from $800-$1200, some guaranteed some not. Is it better to rebuild the original engine or buy another used one? Labor cost on top of an engine wont be cheap. Are other parts under the hood expected to be replaced too as a result of the engine overheating?

My 2000 Ford Ranger XLT 4x4 (139,XXX miles) V6 3.0, recently quit on me while driving on the highway. It will no longer start. I spoke to a mechanic and he informed me to fill the radiator (which was empty) and attempt to start the truck with the radiator cap off. He said that if radiator fluid gushed out then the engine is blown. Is this necessarily the only cause, that my engine is in fact blown.

I have a 2000 excursion 6.8l v10 4x4. While driving on the highway and reaching 80mph, the suv starts making this grinding sound like it's trying to get into gear. The SUV starts to shake. when i drive at a lower speed it goes away. it doesn't make the grinding sound while driving on back roads. What could it be?

I got my Passat about 1 month ago, and I have this pull to the right. Which is annoying, as I drive quite a bit on the highway.
At the dealer, they "fixed" it by moving the tires around and matching tires with the same side wall rigidity. I got my car back, and it's still pulling to the right.

I drive a 2000 Dodge Dakota Sport w/ 4.7L V8 engine. I have been dealing with an overheating problem for about 6 months now and have nearly exhausted all hope of correcting the issue. It has been in the shop on 4 separate occasions and seen 2 different mechanics. The radiator has been replaced, the thermostat and thermostat housing have been replaced, the radiator fan works properly, hoses have been replaced and no subsequent leak has been found by either mechanic, they haven't mentioned the possibility of a blown Head Gasket (nor has the typical "milky residue," shown up in my oil cap). Each time I got it back from the shop the problem was fixed for about two weeks, then returned and slowly got worse.
It overheats in idle (with the fan running), on the highway at high speeds, and while driving slow. Sometimes it only gets about 3/4th to the red (usually when its cool at night) and sometimes it will hover just below the red; while I'm doing everything I can to keep it from hitting red (defrost on, revving engine). Some days it takes a little while to get hot and some days it happens very quickly. I'm tired of sinking money into the vehicle but as a recent grad I don't have the money for a new truck at this point. Suggestions included heater core clogged, water pump gone bad, fan clutch.

Was driving on the highway and all of a sudden my mph gauge just drops and my car slows down. This is the first time it happened and it didn't do it again after I got off the highway. Other things it has been doing: eating gas, shifting hard, and doesn't want to get up to speed. Not sure if they are related to this new problem or not.

Had my transmission software updated today with the 20,000 service. Will give it a test tomorrow and we'll see if the "jolt" is fixed.

I was driving my car about a week ago and when turning onto the HWY it just cut out and stoped running. pulled the key out and put it back in and started right up. Well today the same problem happened to me while i was on the HWY, pulled the key out and put it back in and it started right up. What is causing this to happen?

Just got my H&R's put on this week and it felt GREAT! But today as I was driving on the highway (stop and go) then road began to clear up, I felt a tremble (Shimmy) coming from the front of the car. I pulled over and checked to see if wheel lugs were safely secured and they were also check to see if there was any play on the top of the front shocks and they were ok I don't feel it in the steering wheel, I only feel it coming from the front. This has only happened once in the past but only when the car was parked with the ebrake on, but it was a very subtle tremble, I was wondering if it may be a motor mount that is either worn out or loose and or it will need a alignment given that it wasn't done after the suspension got put on.......

2000 taurus se w/20K miles, transaxle warning light begins to flash while driving at highway speeds only (w/auto climate control on, I think -- at least the last 2 times it happened, shutting off AC or heater allowed me to drive on w/o the warning light coming on again).
I stop and restart the engine and the light is off. May come on again in a few miles or not for a long time. No noticeable shifting or driving/operational problems.
Does it in D1 and in D. I'll have to take it in to get checked but want to be knowledgeable in order to save a mega-buck diagnostic that fails to address/correct the problem.

I've been noticing that my 2012 Passat TDI with 125,000 miles, hasn't been shifting to 6th gear when driving down the highway. I've actually noticed it's one gear too low even when driving down city streets. We have been experiencing extreme cold weather in Pennsylvania, so perhaps that's a factor.
If I manually shift to 6th gear, it stays in gear, but it appears that the engine RPMs are a bit lower than usual as well, but I could be wrong there.

Just had new front tires installed today and drove home. Car felt fine driving at 60 kph. Drove tonight on the highway and felt a bit of shaking. Its not as severe but can be felt sightly. Didn't feel this (slight) shaking with my old worn tires at highway speeds. What could it be? Btw, bought the car used last year at my local dealer and I haven't done an alignment yet since then.

Lots of SAFETY concerns . At 927am Feb 15, 2105 while driving at 100 kph on the highway (25 min) my drivers door opened to the safety stop by itself!
While driving and turning the corner my radio occasionally changes radio stations and sometimes goes to MAX volume! You cannot turn it down or off!
Drives door whistles at 70kph took it to dealer 6 times no solution!
My 6 month old Passat TDI Highline is possessed!

This is on an 2012 SEL, 34K on it. Since the last couple of months, I have noticed that there some wub-wub-wub sound coming the wheels, well, at least from the road surface while drivng on highway speeds.
The sound is just like something is touching the tires, but can't be sure. I may have sensed some very minute shaking as well which may seem correlating with the wub-wub frequency. But as you can see, I am not quite sure how describe it. It is not a distinct sound, not something very obvious. But it is there. I asked my SO too, and both of use can notice the sound independently, so it is perfectly reproducible. The sound appears to be coming from the front, but it is hard to pin point. I also tried opening the window at 65 mph, but the wind and road noise just drowns out all other sounds.
I have thought of getting its wheels balanced as the first step. Went to Costco but apparently they balance only the wheel with tires sold by them on them. I am thinking of taking it to the dealership but want to be prepared by some basic info myself. Hence this question. Hopefully, they wont come and tell me that the wheel drive shaft or some such needs to be changed.
