Passat (B5) :: Loose Heat Shield / Minor Rattle Occurring At 1200 - 1400 Rpm
Jun 24, 2002
I have a 2001 Passat GLS 1.8T Tip 34500 miles... Loose heat shields. Well, I couldn't find anything to fix, so I brought it to the dealer. They said that this was common on 2001 Passats with about 30k miles. All stock.
These were the symptoms that the car was exhibiting: At first it was a minor rattle that occurred at 1200-1400 rpm.......only when the engine was warm, and only when I was in drive. (I could not reproduce it in neutral)...
A few weeks later, it the engine rattled upon startup for half a second. I assumed that this was just the heat shield issue getting worse. Dealer says that I have a bad cam tensioner, and that they will replace it under warranty. However, I had to reschedule the repair for this week because they couldn't fit the 5 hour job in on Saturday.
He said that there is a spring backup for the hydraulic tensioner, but to get it fixed soon. Obviously I was going to have it fixed ASAP. What this cam tensioner does? Isn't there a chain that connects timing belt to cam shaft? Why does this need a tensioner? Does it change in tension?

My heat shield was loose and my dealer said it should be fine, but then it stormed and driving home I ran over a branch and when I got home I noticed the heat shield was ripped and dragging on the ground. It is pretty torn up and I'm thinking of just taking it off. Am I allowed to take it off? If so how should I go about taking it off?

The catalytic converter shield is tack welded on the front end but free on the rear end. There was originally some braided wire packing at the rear to keep the shield from rattling against the pipes. Mine was deteriorated and had been damaged, I think, when I sustained some oil pan damage last summer -- big jolt to the system when running over a muffler on the highway.
The fix is simple. Bought a foot of 3/16" braided stainless steel cable. I used about 8 inches and layed in the lower bead line on the catalytic converter shield (see picture below). You can see a bit of the cable thru the gap in the upper/lower shield on the left side. (1/4" cable would be a better fit, but this will work for a long time.) Cost: $1.84
The local VW parts man dug out an exploded drawing of the system but it showed NO parts or packing for this problem.

I am very mechanically inclined and up until now I can usually hear a noise and know exactly what the problem is, given enough time to listen..
The best I can describe the noise I am hearing, sounds like a cross between heat shield rattle or a syncro somehow stretched out and is loosely spinning around once in gear.. Hard to explain, but all gears shift perfectly..clutch was replaced at 102K and I am currently at 130K. Also I might be crazy but it sounds like I am starting to hear the noise in 3rd as well. I would post a sound clip, but its so faint it doesn't show up on my iphone..
The reason I am throwing it out there, is because half of the seriously trusted mechanics I know say it sounds like a bearing in the tranny going out, the other half, (3 of 6) can't even hear what I am talking about but its there.

Recently I have gotten a very loud and annoying rattle coming from my heat shield I think. I jacked the car up and tried to locate where the issue was but that wasn't successful. Do I need the heat shield by the muffler? And do you think it could be my cat rattling?

I have a 2010 F150 FX4 with the 5.4L, and lately under slow movement (less that 20km/h it is sounding like there is a rattle. I can try to get a video of the sound later, now I'm wondering if the universal bearings in the driveshaft would be making this noise or if it could be the 4wd actuators failing? Would either of these make a loud rattle? (Sounds like a heat shield shaking but all are tight). Had a Ranger up until last year so just learning the ins and outs of F150 life.

I've noticed that potentially my heat shield or whatever guard that is 1 step toward the front of the car from where the inlet pipe connects to the exhaust system may be the reason for my rattle at 2k and 3k rpms. i think its a heat shield but I am not sure. the thing is it seems properly mounted, nothing is cracked/broken/or loose. But when I do try and wiggle it it does make a slight creaking noise that sounds similar to the rattle I get. So I could foresee this as being my issue.
But, is there anyway to fix this rattle w/out just taking off the part? i figure its there for a reason and it looks like its held on in 2 places. But they're not nuts they almost look like spot welds or something. 1 on each side. What to do?
Something to get you all in here:

I recently purchased this truck and have towed a couple of times with it. It has 98,000 miles and I do not know if the automatic transmission fluid has been changed. Should I have it flushed or drop the pan and change it? I have a lift so doing the change is no problem, although it might be worth it to pay a transmission shop to do it.
Also, I hear what appears to be like a heat shield rattle or something that sounds kinda like an exhaust leak during loaded acceleration. What to look for to locate the noise? One last question, the air bag light is on sometimes then off sometimes. Any known air bag light issues? I love the truck, hate the gas mileage!

I bought a 2005 wagon from a local dealer with 21K miles, the 1.8T, an automatic and 4mo. It was certified and still has 2 yrs and 24K miles on the warranty.
Anyway, I there is a rattle/rumble/vibration anytime the engine is at about 1200 RPM. I usually happens on small inclines, and doesn't matter if you are decelerating through 1200 or accelerating through it is makes the noise. I can get it to sustain itself if i keep it at 1200 on the gas or on the brake.
I am hoping it is just a heat shield that rattles at the certain frequency the engine makes at 1200, but I don't know. It is kind of right at that point where the transmission engages and disengages, torque converter?

Finally took the Wolf in to see about an engine rattle thats been getting worse. The culprit - loose engine mount bolts! Dealer decided to order new bolts, not just tighten the old ones. Also mentioned a recall for the transmission software. Odd that the "recall" wasn't listed on-line for my VIN. It must be the one that smooths the tranny a bit, it is a bit jumpy at low speed.

Minor rattle when going over bumps! It sounds like drivers side rear... I have had a chance to check of anything in the car was loose (spare tire tools etc...). Found my problem, now I just have to confirm its the rear driver seat belt not resting correctly.
1. Intermittent rattle behind driver
-check rear seat belts that they are actually resting on the cushion loop.
-check rear passenger window switch.
-check door strikers
2. Bass rattle front doors
-check with dealer
3. Rattle at rear of car
-check spare wheel and tool compartment.

Ordered my TBE couple of weeks ago, installed last week. I have been running the 100 octane tune for an entire week. Decided a couple of days ago to put it back to stock to see the difference. When I was running the 100 oct, I was pretty much on it the whole time. When I went back to stock I noticed some heat shield noise so I took it back to have them take a look. While on the lift I noticed a lot of soot in three different places.

I have a major rattling sound from under my car... it sounds exactly like a heat shield. I have been up under my car 5 times and I can not find a loose shield anywhere. the cat insulator mesh is still in perfect condition and it now seems the sounds is coming from somewhere in the back of the car, perhaps the muffler area.
This car does have the flapper mod done... could there be something inside the muffler itself? the car only has 40k on the ODO and I have not hit anything or do not have a dented muffler. As a fellow VW'er I do not want to be the only one running around town rattling...

I have what I think is a heat shield rattling at around 2500-2700 rpm. or maybe not? It's not that noticeable but it's driving me mad
Is there a more simple answer that it could be? Keep in mind I claim very very little mechanical knowledge.
I am going to my dealer tomorrow for something unrelated and I kinda want to get a head start when I go to talk to the service dudes.

I have a CTS Turbo intake and have recently purchased a heatshield. It did not come with instructions. I tried installing it this weekend and it was a no go. I'm assuming the pieces for the factory engine cover in the rear is what the heatshield needs to replace to bolt on. I couldn't get those off for the life of me.

I have a 42 DD tb exhaust. And so far I've used a 3" exhaust clamp over the last hanger (after the muffler) which raised the exhaust all the way up against the heatshield, eliminating the rattle over the rear axle beam. But the exhaust was rattling against the heatshield.
So I bought 15 ft of exhaust wrap and wrapped the section that comes in contact with the heatshield. It worked a bit but it still rattles a little! I hate this rattling! How to get rid of the rattling? Should I just use more exhaust wrap?

I was driving down the PA turnpike and heard rear-end noise. I pulled over and this piece was hanging down on the right side in front of the rear tire and at the back edge of the rear door, right where the muffler is. I did a search and found this to be a common problem with the 330s but did not see anything on the 350s. I drove another 500 miles to the beach and then back home without any noticeable affects, but not that I looked underneath.

Had an annoying vibration when pulling from a stop til up to speed or if I was going up a hill at low speed. Figured it was the exhaust heat shield so I took it in for service. I was told that it was indeed the heat shield and that there is a service bulletin regarding it. I believe they repaired it with a pair of clamps.

Looking for a cure for a heat shield that continually loosens, and causes a annoying rattle? I have been up under the car and re-tightened the suspected shield a couple times, the screw that holds the clip is not damaged, and the clip itself is not damaged... and on top of it all, I can never quite get that clip on tight enough to stop the rattle all together. is there a tool to get it tighter? i use micro needle nose pliers that fit and tighten it that way.
