Passat (B5) :: CEL Started Flashing - Strange Noise On Speed / Bad Odor Coming
Nov 29, 2011
I have a 2000 vw 2.8 v6.
I got it back in February and it ran great up until now. A couple months ago while driving home my cel started flashing and right when the light came on I could immediately feel an immense loss in power and when I got to a red light it would shake like mofo. Gettin up to speed was suddenly a huge problem and the car would make a strange noise and I could smell a strong odor of gas and slight oil. I have a valve cover gasket leak that I paid 300 bucks to replace but after a week I realized it's still leaking oil so that 300 bucks just went out the window. The sluggish performance and cel went away the next time I drove the car and it ran awesome for over a month till one day while I was on my way home from grabbing some lunch it all of a sudden started happening again. Sluggish performance, smell of gas and slight oil, wouldn't get up to speed.
I brought it to my local vw dealership to have it looked at yesterday figuring that they'd be able to tell me exactly what was going wrong. I got a call early this morning saying that the oil leak in my valve covers are causing my coil pack to short out and foul my plugs and wires and then told me it was going to cost 1,700 bucks with all the parts and labor. I'm not very mechanically inclined when it comes to vehicles so it's not like I can do the work myself but my main question is, how can the oil cause the coil pack to short out seeing that oil is not conductive and some cars actually use oil to cool the packs down. Is that a legitimate diagnosis or is the dealership mechanic Actually right or is he just getting creative trying to squeeze some money out of me.

Blower works intermittently. Sometimes all speeds will work. Sometimes only on high. Sometimes on all speeds but at a slower speed than normal. Sometimes it doesn't work on any speed.
Switch doesn't bind, blower motor doesn't make any unusual noises and I don't think it is the blower resistor. He did notice a strange odor coming from the vents the other day and, it appears that the foam on the blend door is starting to disintegrate.

At work we have a 04 Passat 4motion wagon that has a strange noise coming from behind the dash. The best way I can describe the noise is like computer hard drive loading. It happens continuously even when the radio/cd player is on.

I have a 2014 passat 1.8T with 2500 miles. I noticed that i am starting to hear a noise mainly when coming to a stop. Sounds suspension related , sounds like a suspension spring sound - kind of hard to explain.Only 2500 miles and strange noises already?

Had a bad smell coming from the a/c vents when you first turn it on. Goes away after a couple minutes but it stinks... My passat still under warranty, wanna be able to tell them what's wrong when I take it in.

In the last few weeks the odor coming out of my AC is pretty stinky. Is there something I can check easily or does this require a dealer visit? Also in the last month I hear a strange "warbling" noise as if my car was on SUV tires. I do not work on my own car but would love to learn if it isn't too hard .

My 2008 Prius with 105k miles recently started having a strange clunking noise when turning at low speed. Dealership diagnosed it as the steering shaft and yoke to replace.

I'm new to vw and I have a passat 3.6 sel premium and I have been hearing a noise coming from my rear suspension when I have a full car or going over speed bumps and such. It took it to the dealer and they said that they couldn't replicate the problem, could it be the control arms or it's bushings? The car is only 6 months old smh.

So on the 16th I had my Koni FSD kit installed with a set of Driver Gear springs (30mm drop) and used the ECS Tuning install kit for both front and rear.
The issue I'm trying to troubleshoot is a 'thunk' noise coming from the rear but only when going over speed bumps or any other major bumps/dips.

I'm battling an odd suspension issue...over the last 5-7,000 miles, I've had a strange vibration issue surface that has varied in intensity depending on speed and road surface. I've had a damaged wheel trued, replaced all four tires and had all four wheels/tires RFV balanced. The vibration has changed but not quite gone away. Instead, it's been joined by an increased vagueness in directional stability (tendency to wander) at highway speed.
Last week, the tech balancing my tires said he felt my right hand front rear control arm bushing was worn. The more I've thought about this, the more I'm wondering if this is what might be the source of this mystery vibration issue. So, I really have two questions?
First, bad front CA rear bushing replaced under warranty? 15,000 miles does NOT seem like an acceptable service life for a suspension bushing? Do these bushings have a history of premature wear and failure, or am I just lucky?
Second, if I do have to replace one or both bushings (left and right pt. no. 5C407183A,) I'd like to ask if the solid bushing (pt. no. 1J0407181) from a Jetta or Beetle will work in a Passat control arm? If I do have to replace the bushing, it might be better to put a more solid piece of rubber in there instead of the flimsier original part.

I own hyundai 2000, 1.5L. About 5 days ago the engine started making strange noise that sounds like sewing machine.
I went to my garage and they said that its the hydraulic valve lifters and that I should replace all of them(12 total).
My question is, what can happened if I wont replace them? can I postpone the replacing for a few months or it can cause damage?
By the way, I heard that the noise from hydraulic valve lifters can start due to bad oil, I had 20W50 so I changed today the oil to 15W40(manufacturer recommendation) and the oil filter and still got the noises.

Ok I have had this noise going on for about 1 week before transmission went out. I just built the trans and its still there.
I had a mishap years back with front end hub bearings so I replaced with New Timken Bearings. Well that wasn't it but at least I know where I
stand with those. It starts making a noise when slowing down about 3-5 seconds before coming to a stop. I thought maybe the carrier bearing in
driveshaft?
Pinion bearing in rear diff? I need to service the parking brakes on rear so I may pull it down and go through it.

Just bought a '15 Golf TSI S/sunroof with the 5MT (night blue, for the curious). Anyway, I've been getting a strange noise that was not present on the test drives, but that I first heard driving home from the dealer about a week ago. Since then it has happened intermittently, and not reliably enough that I've brought it back to inquire about. It is hard to describe, but sounds something like a whir and whine together. Typically it starts when I am in gear -- 4th, usually, though I can't figure why that would matter -- and then take my foot off the gas. If, however, I put the clutch in or put my foot back on the gas, it won't stop right away. It does stop when the car comes to a full stop. I'm beginning to suspect that it happens more when the car and/or the day is very hot. The times I've heard it most often, it has been over 90* outside, and the car has been driven for at least about 10 minutes.
I drove around for 25 minutes this morning and it finally did it, so I hit the sound recorder on my iPad. For reference, this morning it was about 81* out.
Here's a video link to it. It occurs at the 1:13 mark, if you want to skip ahead, but it's pretty faint over the background hum. The sound is clearer on the actual recording when I play it back on my iPad. [URL]........................................

So, a couple days ago, my car started to shudder a little bit and the check engine came on and started flashing. I pulled over and restarted it and it came back but then it went away. I tried to take it to Auto Zone the other day but for some reason my car wont communicate with their diagnostic computer. I read that its probably the coil packs but I want to be sure before I spend the money. I changed the spark plugs which were in desperate need of being replaced and it went away for a day and the CEL went off but it just came back today. I'm gonna try a different auto parts stores diagnostic computer before I give up on checking that.

In the past couple of days I have noticed a strange clicking type noise coming from the glovebox and it is coming from the Nav Unit.

About a two weeks ago, I had a CEL pop up. I brought it in to the stealership to get it scanned. I don't recall what the exact code was, but the description was something to the effect of "Cooling System Performance." I hadn't noticed that the engine temp was any different than it had ever been, so we kinda figured it was just a bad sensor. We popped the hood just to take a look at things, but he didn't really notice that anything was off. I thought the engine sounded a little difference. It wasn't idling rough, but there was a very subtle ticking noise. He didn't think anything of it. So he cleared the code, and sent me on my way.
The code came back a few days later, but disappeared about a week ago. Since then, however, my .:R has been feeling a little different. Like I'm losing torque. The ticking noise has become distinctly louder, although I can only hear it when I pop the hood. Last night, i was listening to it, and there are two separate noises, coming from two different locations. One is coming from the left side of the engine, most likely from one of the belts. The other is the one that worries me the most, as it's quite a bit louder. This ticking noise seems to be coming from the engine itself. The longer I let the car idle, the louder it gets.
One of my friends took a listen, and he suggested that it could be a blown piston ring. This would explain why I'm losing torque, but I haven't noticed any blue smoke coming from my exhaust.

Ii had drove my car about 20 miles and after i had got inside and turned it on to drive it again CEL started flashing and car was sputtering lost power and felt like it didn't want to move so I had taken it to a VW specialist and he diagnosed it and told me its my coil pack and its got a bit water inside it and I would need to replace it and he said he would charge me $300 to replace ...
So I figured if its just the coil pack I could most likely do it myself and could this be from the coil pack? and why would there be water in my spark plug? Should I replace all coil or just the one that's bad.

My son's Elantra is making a strange sound, which seems to be coming from somewhere in the rear, underneath the vehicle (in between the wheels). I can hear it with the car parked, idling. In gear or out of gear doesn't seem to matter. It's not very loud, but it's rhythmic. I checked the engine compartment, but I can't hear it at all up there. I *think* I can hear it while driving, but it's very hard to hear over the engine and road noise while driving.
The sound reminds me of a squeaky pulley, with a period of 1-2 seconds. The car has been serviced recently, and the mechanic said it was in great shape. Mileage is ~50K.
