Passat (B5) :: Cannot Get Speed Above 20 / Misfires When Try To Go Faster
Sep 30, 2007
My 2000 1.8t passat is quiet sick and i am unsure of where to start. here are the symptoms:
- rough idle for a minute or two when started cold
- occasional erratic idle
- low power
- the CEL would blink for 10-20 seconds on startup
- checked and cleared the codes at autozone, and now the car seems to be in limp mode. engine has NO power, cannot get speed above 20, misfires
when you try to go faster
Where are the codes that were stored:
-P1136 Air/fuel metering
- P1128 Air/fuel metering
- P0507 Idle control system, RPM high
- P0300 Random Misfire
- P0301 Cyl. 1 misfire
- P0302 Cyl. 2 misfire
- P03011 Cyl. 4 Misfire

I recently had my 2002 1.8T in for clutch replacement at the dealer and they came back and said the crankshaft was bad ( the car was occasionally making noise when pushing the clutch in, they thought it was a throwout bearing) I took the car back to bring it back to an indie, and it is loud at idle and while accelerating (sounds like a chattering noise that gets faster as speed increases) It's now sitting in the parking lot. My question is, am I going to have to put in a whole new engine to fix this problem? can just a crankshaft be replaced?

When I start my 1999 1.8 petrol passat it needs some throttle to start, low idle speed, misfires, drop in idle, so boot the throtle full - still no pick up and sits on 1000 rpm busy backfiring away! It started after fitting a new windscreen wiper motor, battery was disconnected but went back ok, all other electrics work and no warning on the dash. Didn't touch anything in the engine bay nor were there any issues before I changed the wiper motor.

I have a 2012 Camry SE I4. The problem is my car speed odometer is faster than my radar detector speed. I have 2 detectors and they are both not show the same speed compare to the speed odometer. For example, I am going 70mph, the detector reads like 67-68mph. So the speed odometer is off about 2-3mph. I have OEM size on my car. I know the GPS on my detector is more accurate. So my speed odometer has problem?

I've read several posts that suggest the EV mode is mostly useless. I disagree. I've noticed that it's useful in gaining speed faster without the ICE, when taking off from a stop. Especially if I'm in traffic and I don't want to annoy drivers behind me.
I've noticed that conditions have to be met in order to do this, such as engine warmed up etc. but I find it very useful, and I am seeing improved MPG when doing this. I've had my 2013 PRius v Two for almost a month now.

My i40 (18 months old and already on it's 5th problem) has just developed an enormous noise (thud thud thud) when going over 15mph and gets faster with speed. If I go into neutral and turn the engine off at speed it is still there. The crazy thing is as soon as I veer or turn right it stops but when I turn left it does not stop. It's really lot and I can feel it through my feet and on the steering wheel. I am taking it into Hyundai (again) but I'd like to understand possible issues before I go in.

I have a 99 tahoe 4x4. It has 220000 miles. I had a wheel hum that got loud when I went faster and the pitch changed with speed. It doesn't seem to matter if I swerve left or right. I took it to a dealer and was told I needed bearings, both wheels. I bought the wheel hub assembly and changed them out. I figured it is just better to change the whole assembly. Well, I still have the hum and it seems to be getting worse. I don't know if the u-joint would do that or if it could be a shaft thing. I can not tell what needs to be fixed but can usually fix them when I know what it is. I don't know if there is a transfer case problem either? I know the shaft spins when I turn the wheel. I assume the lock for 4x4 would be in the transfer case? It seems to be getting worse and I don't want to do any damage. I don't get paid for another week and have to drive 50 miles a day.

Got a 2004 Chevy Impala with 99K miles. Speedometer seems to be acting sporadically often. Sometimes, it will shift 10 or 20 mph "faster" than actual speed then, sometimes, it goes to the "maximum" speed on the dial and just stays there with the car on or off. Then a few days later, starts working normal again.

Ford F-150, 1994 : intermittent problem. going down highway, foot on the gas. At times, will press accelerator to go faster but nothing happens, like clog somewhere. Sometimes, with foot still on gas, i will hear a popping sound coming from under the truck, (under the engine?, or drivers seat). Usually 4-5 pops, sometimes none. But after each pop, car accelerates slightly, as if it is a slight clearing, until finally, as if some clog was opened up, the car plunges forward, so i then take my foot off the gas. Sounds like either problem with fuel getting to the engine or a problem with the exhaust.

Having an issue with the 09 Platinum 5.4. Recently the air ducts to the passenger side have been routed straight to hell. The blow hot regardless of the setting, the driver side is fine. I can hear a clicking noise that gets faster/louder with the fan speed on the passenger side. I am thinking blend door motor? Possible location of this part and some replacement instructions? Wife and kids aren't digging this hot heat all the time, its a very uncomfortable ride in such a great truck!

My fathers truck starts, runs, idles fine but once on the highway at constant speed, the engine misfires or hesitates causing a small buck or jerk but continues on down the road. The SES light is on. He took it to O'Reilly and they put some kind of computer on it and (I think) it said misfire in a cylinder. He replaced one of four O2 sensors, pickup in the distributor (not sure what this is called), wires, and plugs with no cure. This problem is very strange as again, it only does it a constant speed; truck runs fine at idle, acceleration, deceleration, startup, etc. There may be a slight sulfur smell during idle and there is a decrease in gas mileage.

Ok so I dropped off my 06 at the dealer for some warranty work and got an 08 for a loaner. They are both 2.0t tips. The 08 is a ton faster than my 06. It spins the tires all thru first gear if you turn off the esc and stand on it from a stop. I thought mine felt good but this one is better.

This seems a little odd, but I noticed that the right turn signal blinks much faster than the left turn signal. Is that a VW thing or does that indicate some other issue?

I have a 2007 Passat with 47,000 miles on it. The dealer tells me I need new rear brakes now, but the front brakes have 50% life left in them. When I asked why the rear brakes are wearing out so much faster, he said VW rear brakes always seem to wear out twice as fast. Is this true?

OK. I have a 2005 Passat 1.8t fwd. Tiptronic. 105k
The symptoms i am having is random cylinder misfires on all 4 cylinders. I have scanned with vagcom multiple times and get the same codes. However, I have cleared the codes, and wen fpd a 60 mile drive on the turnpike. Not a single code. So everything is perfect as long as the car dissent have a chance to idle.
I have also driven the car while logging misfires and only get misfires at idle. Never while driving.
So much has been done to the car that is so hard to decide where to start. Ill try to go in order of events.
All this in the past 4 weeks by the way.
Took car to very experienced VW tech. Found out.timing was off by 3 degrees. So new timing belt, water pump and all. Started car, still had misfires. Noticed wetness on head gasket. And did a compression test. Very bad results. (I can't remember the numbers but they were way off from each other) So he removed the head. He said there was a crazy amount of carbon buildup in the combustion chamber. Everything was cleaned, head inspected for bent valves and everything looked perfect after cleaning. (this car has NEVER overheated by the way) He said it is very rare for a head gasket to fail on 1.8t's . So he did a leakdown test and turned out the piston rings were shot. So engine was rebuilt. All components cleaned of carbon, replaced all parts, bearings with new OEM parts. Pickup tube cleaned along with other oil lines. Turbo was inspected, and I was told it is on its way out but still has life. So that was let go for now. All reassembled and all hoses checked, combi valve cleaned, new k&n filter in stock airbox. So he told me the car is finished after all that. I was excited! Drove the car home 15 min drive, ran great. Parked in my driveway, put it in park and misfires came right back. Called him the next day and brought the car back. He looked over it and replaced the fuel pressure regulator with new. He said it seemed like a fuel starvation issue. Tested fuel pump and it was towards the low end of the proper operation value. So I had a high flow pump sitting at home brand new and I brought it down and put it in. Still misfires but a lot less than before. Also fuel filter was replaced. So next he disconnected the cat And found it was clogged. Replaced with my old Audi one, and it ran fine. And this is the first time the car idled good enough to get all the monitors set for emissions testing. So he was convinced it was fixed. Room it for a test drive and came back, parked And began misfiring again. So I was so sick of this thing at this point, I told him to replace the Turbo with brand new OEM unit. And it still misfires.
He swapped a known good throttle body into it and no difference. He also said that he started going around and unplugging sensors and the more sensors he unplugged, the better the car ran. He was curious whether the ECU was faulty. So he put an ECU from his Audi in it which had a ko4 file in it. He said it ran amazing!! So he modified an ECU from a stock Audi and that's what I am driving with now. Still same symptoms. But not as often. Also brand new bosch mass air sensor was installed as well. So this is as far as we have gotten with it and I am so sick of this car right now. But we are both determined to get this thing fixed! And after all the money I have just spent, I can't even get rid of it or I will lose a lot of money. It really sucks because I love the car and so does my wife. And out of the three 1.8t's that I own, I have never had any major issues like this.

My front right tire has been squealing when I turn. It also makes a high pitch tone when driving on the Interstate or at faster speeds. (It might be the wheel barrings - is that the same thing as a CV joint?)
Is the power steering fluid found under the green cap, under the hood? Cause I checked that and it was filled. What do I do? I don't like the squeak when I turn, nor the high pitch constant sound when driving on the interstate. Also I just posted a report about really poor gas mileage. Could these problems be connected??

I know the ignition coil are a big thing but I'm going to be buying this car this week and so I need to see how much less to offer the guy because of this issue. Is there anything other then the ignition coil that it could be? What's worst case scenario? And also would it be ok to drive it home about 60 or so miles with this going on? I'm guessing it's doing the misfires at idle.

I have been reading threads all day. Noone seems to have exactly the same issue so I'm just looking for some clarification. Turn signals dont work but lights work as "parking lamps" and internal climate lights are not illuminating either. Also, my blinkers making the clicking noise but much faster when the turn signal bulbs are not flashing. I had a radio issue but that is resolved. Where do I start? Do I go right for the hazard relay? I read somewhere there was an ignition relay that could potentially be causing all of this?

I drive a 99 1.8t Passat with 90,xxx miles. Yesterday I felt the car hesitate/jerk a little when it's accelerated to 35-40 miles per hour. I've had this problem in my past and it was a cylinder misfire. I would bring it to the repair shop.
My question is: Can my car last about 1.5 weeks? My work is 20 mins away. I can definitely avoid the freeway.

So I took a trip from Dallas to Florida, and on the way back my check engine light came on. The car shakes at idle, almost like it wants to take off. I drove it back to Dallas like that since the car runs normal on the high way. I got it scanned at autozone and the code said it had multiple random misfires. I'll be taking to the dealer in the morning, but what it could be? The car jumped over 50K during the trip hopefully the dealer will be nice and cover it.

My 2.0T 06 Passat misfires sometimes during cold start after 6-8 hrs of parking. It happens very rarely. I have had the car for 4 years (bought it brand new) and the misfire has happened about 5-6 times. Is this normal? Just wondering if they get logged in the computer system so VW Service can see it? My car has got 47K miles on it.
