Question about 2000 Volkswagen Jetta TDI

1 Answer

Contracting and expanding noise

After a couple of minutes after turning on the engine one hears clicking noises from the front bottom of the car. When switching off the engine there is a contracting sound of hot metal form the manifold. It appears to be getting louder every time. What could be happening?

    Thanks Dicky,



    The engine is a 1600 petrol motor and not a TDI. I have checked the fluid level and it is OK. I took it to the VW dealer and he claims that everything is OK. He said that the noise from under the car is from the catalyst in the exhaust. The noise from above is the catalytic converter. I am a little worried as I did not hear these noises before hand.

Hi,
First of all check that you have coolant up to the marked level in the expansion tank - just in case you are low and the warning systems have failed, then get a list of fault codes from the onboard diagnostic system and take it from there. You could either go to a VW dealer, or if you are technically minded you could buy a £15 interface cable, download some free "VAG diagnostic software" and run it on a portable computer.

Guessing at faults on a TDI - apart from the very obvious ones - is usually somewhere between very and extremely expensive :-)

I know this isn't going to sort the problem immediately so hold off the rating bit and come back when you have the fault codes or have got it fixed. I'd like to know what is wrong.
Cheers, D

Car overheats makes a loud clicking sound from under the hood


The loud clicking and/or ticking noises that emanate from an overheated engine is actually the metal parts expanding or contracting due to the heating or cooling down. This is a sure sign of severe overheating.

My 2000 porsche boxster is making a clicking noise and its on the right side of the engine and it looks like a oil leak on the same side to


The clicking noise is just the car cooling down and the metal components in the exhaust expanding and contracting. nothing to worry about. And it does look like there is a reasonably bad oil leak. Make sure there is enough oil in the engine before driving it and take it to get a seal or gasket replaced to stop it.

Can a turn signel work for about 15 seconds and then stop? or could it be the relay?


the flasher unit is probably worn out.there is a bi-metalic metal strip that gets tired and won`t expand and contract making the clicking noise you hear when the signals are in use.it stops expanding and contracting causing the flashers to stop working.change the flasher unit but make sure you changing the one for the signal flasher and not the hazards flasher as they look the same.to know which one turn on the hazards and look for the other flasher that is not making a noise as this will be the one for the signals.

My Audi A4 2009 makes a rattling noise on cold starts which resolves in less than 30 seconds. Dealer says its an air pump. This doesn't seem correct. The noise comes from the front of the care. Does not...


READ THIS (happy ending so far...):
audi a4 2L turbo quattro, manual transmission with 98,000 KM. Perfect conditions, no oil leaks whatsoever.

Left the car off for two weeks in very cold weather (-10C down to -25C). When I restarted, it started immediately but with heavy rattling noise due to camshaft adjuster not getting enough oil pressure. After 3 minutes of warming up (outside temp.: -12C) at very low rpm (below 2,000rpm), I start moving the car. Still hearing heavy rattle noise. As soon as I pass 2,000 rpm, I get a scary red warning, low oil pressure. Turn off the engine immediately. In 1 minute, I re-start the car and the engine lights check ok, so I drive in first gear super slow (1,200rpm) hearing the same rattling noise. After another minute, finally the noise all the sudden disappears and the car starts running just fine.

Called Audi dealer and they told me that in extreme weather conditions, I should warm the engine for 10-15 minutes if necessary before start moving.
Take away: luckily, I didn't screw up the engine since I was using it at extremely low rpm (easy to do with clutch and manual transmission) until the oil reached full pressure. I am pretty sure now that the problem was leaving the car off for such a long time in freezing weather. All the oil flows back to the bottom, and when I restarted it, the cold oil with high viscosity took a long time to reach all the parts of the engine, specially the camshaft adjusters that are actuated by using oil pressure. Next day, the car started at -9C perfectly without making any noise (as usual). Basically, the longer you leave your audi in cold weather, the longer you might hear the rattling noise until the oil reach full pressure inside the engine. My car took 6 minutes to fix it after couple of weeks in cold weather. This makes sense to me; in fact, in the past I only heard the rattling noise after leaving the car off for a couple of days in the winter.
So far, this has had an happy ending....

Why does car make constant ticking noise from metal expanding and contracting . Even makes ticking noise when running. Same noise you hear when you turn car off.


The exhaust system on your car is stainless steel, and it heats and cools quickly, there is nothing wrong with this. all your hearing is the joints in the exhaust system expanding and contracting. My 2007 impreza 2.5 does the same thing. And when you turn car off the system is cooling off and contracting.

02 silverado gas tank popping noise after startup & shutdown


It could just be the heat shield around your exhaust expanding and contracting again when your engine cools down. Sounds like a tin can type of popping noise?? If it is that's the heat sheild from the engine that protect's the spark plug wire and around under the truck cabin. Good luck and hope you find where the noise is coming from.

Mazda mx 5 engine noise


the noise is caused by the hot exhaust, all cars do this, the exhaust gets up to 1000 degree's. The noise is the metal contracting as it cools, it is a clicking or popping noise.

Exhaust manifold gaskets


the ticking noise when cold is an exhaust leak.If it is the exhaust manifold gaskets,depending on the vehicle they can be very difficult to replace.in some cases you must remove many other parts even to see the manifolds.make sure when manifolds are off that they are checked for warpage,this is a simple test needing only a straight edge and feeler gague.ask your tech if he can see any broken manifold studs/bolts and if quote covers time for removing broken manifold studs/bolts,because if any are broken,this can take quite some time to extract the broken studs/bolts.
