I've noticed today in my GT TSI that the sound from the engine bay was pretty loud when the A/C was nearly at full blast (80% of the full speed). I noticed this today as I got out of the car while the A/C was running on an extremely hot Pune afternoon (usually when I go to work & come back, it is in the morning & at night, during which temperatures are not high, so I did not notice anything abnormal).

The sound was normal once the A/C was turned off. I just wanted to check if this is normal (is this just the compressor running at full blast?)

Hi all,

I have noticed lately that our 2014 Volkswagen Jetta TDI has been making a chic-chic sound for the first minute when it is cold started. The sound then disappears. The car has clocked around 40K.

I asked the S.A once and he said it is the alternator belt making this noise along with the pulleys due to friction when cold. Can this be possible? I have never come across such a thing and thus asking.

[MinivanDriver]

That is a plausible explanation. A check to make is to switch on the headlamps immediately after starting from cold. This should cause more load on the alternator and sound may increase. I once had this issue on my old Maruti 800. It was fixed by slightly bending (or straightening; not sure which was the case) the pulley mounting using a long flat iron plate as a sort of crow bar. In your case, changing the alternator belt if needed could be the solution if the problem persists.

I have a Polo GT TSi which has run 11.5K kilometers. Of late, I have been hearing sort of a grinding noise in 3rd and 4th gears. The sound is speed dependent and occurs mostly when the car decelerates and is in the 20kph to 40kph speed band. Also, in general I feel that the car has become a little gruffy and noisy. Anyone else notice this and found a solution?

EDIT: Could this be because of an issue with the wheel bearings?

My 10 year old Innova gives a metallic clang clang sound when in neutral. It is kind of off and on. The sound is coming from under the vehicle. It is not audible from inside with windows closed. When the clutch is fully depressed while stationary, this goes away. Sometimes I hear the sound while moving as well. But usually it goes away while running. The service center guy says to replace clutch. There is no discernible loss of power in gear. The vehicle seems to push ahead well while releasing the clutch with hand brake on as a test to check clutch wear. Any advice? BTW the vehicle is past 100K Kms and still running with the original clutch.

Should have visited them in the first place instead of wasting 7k at Elite.

I might have a similar issue in my car. Could you please tell me what part exactly did you change? How much was the expense incurred? Right now one garage to which I consulted has informed me that I have to change steering rod on both sides which will cost about 10k for parts and labor.

I think its on the higher side.
If I remmeber it right, the ball joint costed 1300 (and that too for a pair, if I remember right). Labor charges were about the same.

I am facing this noise from the rear left area of our i20. It comes when going over pot holes and rough/bumpy roads. I initially suspected the struts and replaced both the rear struts since they were due for replacement. The noise still persists.


The noise is a hollow clunky noise. Similar to what one would hear if we hit the inside of a damped hollow tube. I removed all the contents in the boot- spare wheel, tool kit,jack etc. Still the noise persists. This noise is driving me nuts. The service certer feigns ignorance regarding this noise and keep insisting that there is nothing . The noise is present for more than an year now and it has become more prominent over the past few months.

Any pointers as to probable cause are highly appreciated. Thank you.

A tin metal rattling sound when I accelerate from a slow speed or from a complete stop, specially in the first gear. The rattling sound is temporary and goes away when I reach 30 - 40 kmph and as I change from 1st to 2nd. Anymore acceleration to speeds beyond that do not make this sound.

I also feel like something is holding down the acceleration of the vehicle during the time I hear that rattling sound. It comes from the front side near to the tires. My car has clocked 82000 kms. I looked through the internet but did not find anything related to this.

From what I could figure out, can it be something to do with either the driveshaft, engine mounts gone kaput or gearbox wanting attention ?

Admins, please pardon me if I missed a similar thread and move if needed.

Seems eerily similar to issue i had seen. Please refer this:

Last Friday, while I was driving my WagonR k10 within the city, suddenly I started hearing metallic clank sounds from the from left wheel area. It used to come while negotiating some of the potholes or speed breakers. It was like a metal pipe hitting another metal and was fairly loud to be heard within the closed car. The car was otherwise fine with no impact on any other performance. I decided I will attend to it after office.

I drove back from office for 11 kms and visited my trusted FNG near my house. While I was >500m away from the FNG and went over the last but smooth speed breaker, I heard a very loud and shrill screeching noise and stopped the car. I knew it was the brakes (which were working perfectly). I reversed some distance (no noise came in reverse) but persisted if I moved forward. I parked the car and called the mechanic to the place.

The guy asked if the wheel was opened anytime in the recent past and I agreed about the balancing and alignment done 1k kms ago. Finally, he opened the wheel and as he had suspected, a small stone (~4mm in dia) was lodged behind the disc.

The wheel cladding (all 4) of my Altis have become loose and they keep hitting with the body whenever the car is on the move. Is it advisable to fix them or get entire new set?

Get them fixed. These are not key items, hence functioning of the car itself is not at risk..

Friends
Need your support and advice here. Offlate, I am observing two sounds in my Qualis.

1. When the car is at low speed, a sound like Brr Brr Brr keeps coming from somewhere. And the frequency of this sound is proportional to speed of the car. This means, when the car increases its speed, Brr brr per second will increase and will vanish (Or atleast we will not hear) after 40-50 KMPH Speed

Hints: Recently I changed the brakepads both front and back. But, there were no such sound after I changed. But now, after running say 2000 Kms, now this sound has started. Could there be any issue in the pad?

2. When the car goes over bumpy roads and rocks horizontally(Left to right and right to left), there is rocking sound krr krr (similar when you open an UN-OILED Door at home) and small thud sounds as well. Initially, I thought Dickey is not closed properly and it is making this sounds. When Dickey door is not closed properly, we used to get the same sound when we purchased the car. But, am now sure that Dickey is not the culprit.
PS: Even when the car ignition is OFF and stationary, when it is pushed from left to right or right to left manually, this sound appears (NOT the Thud sound but kr kr sound comes. This was never there earlier)

Was really surprised to see how almost all of us are able to communicate and understand the sounds of car with various spellings . And many of us are even able to identify the root cause and suggest the solution. This is really surprising

For the first check no cloth or such are caught in the drive shaft. Sometimes such pose items get caught and then whip against body to create such noise. Alternatively make sure no hanging plastic or Robert part is brushing against the shaft. These now back as speed increased and sound disappears.
