Is it normal petrol engine sound?

Valve clatter is very prominent- our WagonR (10/2013- K10BN) idles a lot smoother in comparision.

I'd say a couple of clamps are loose. Check the air filter housing clamps, and I'd also check the alignment of all the assorted belts, just in case.

You could go to MASS, but experience has taught me not to trust those buggers - for trivial issues such as rattle rectification. I had a couple of rattles in the WR when our car was only a month old, and MASS couldn't pinpoint the root cause.

That annoying squeak squeak sound still continues when the car is idling, with A/C on. Have stopped to going to MASS these days. Sometimes I cannot help but feel that MSIL is a good-for-nothing company, although that is being a bit tad tooo hard on them.

I'll try a D-I-Y and get rid of that annoying rattle myself. Guess a couple of belts related to the A/C system are loose. Trivial issue, yeah- but frustrating nevertheless.

So, all said and done, in your case, I'd say- MASS is your best bet. Hopefully they'll sort the problem out.

Saw a maruti video about k10 engine yesterday. So now I know what is where in my cars engine, i am thinking it is valve clatter. Checked for anything loose but cant find any. anyways will take it to mass and will ask them to show me other petrol swift/dzire. Thanks guys.

Hello

I heard a grinding noise on shutting down the engine. Tested by restarting and shutting and the noise remained. The car was parked for a couple of hours after this. Drove it back home without any issues, or any difference in performance. Tested again at shut-off and the noise had vanished. What could be the reason? Is it a symptom of something going wrong? My car is a Skoda Octavia 1.9 TDI.

Difficult to give any diagnosis with so little to go one. When this symptom strike next you can share more detailed description. For now get your car checked out in a garage.

Hi Ashokkp,
I appreciate your concern and I am happy to see that you care for your car.

When you see the symptom next time, record this abnormal noise on your cellphone. Do this inside the cabin so that there will not be any noise from the surroundings.

Post the sound clip here and also share it with your service adviser. This will help proper diagnosis.

Is the car under warrantee?

Sometime back I noticed noise on the front right side of my 2010 Alto. Sounded like, it was coming from suspension (thud thud thud noise but not very loud) when I drove on bad road, after a long drive. During short drives this sound is not present.

I went for an inspection to A.S.S and after checking they said it is from steering unit. One of the bushes is weak. They replaced it and greased it. Now there is no sound. When I asked him why the bush was damaged, he answered that I have parked my car in sun for long time and therefore the bush is worn out. Also if engine becomes hot after a long drive the effect of grease deteriorates and the sound may start. He asked me not to park the car in sun for long and to use covered car park. He also mentioned that there were many cases with Alto and wagon R where they ended up replacing the whole steering unit due to this issue.

I am not very convinced by his answer. Especially in India where we have abundant sunlight most days in a year how can Maruti Suzuki expect us to park cars in shade all the time? Has anyone faced similar issue?

I got my polo tdi 1.2 highline last year. It was running fine for last one year. Recently first service was done and now for past one month of service am hearing loud buzzing noise if I switch on the air condition . Not too audible inside the cabin but it is very loud on exterior. If I run the car without air conditioning then cooling fan is running more than 5 mins after car key is removed which was not there before service. Usually fan will run not more than 30 seconds before service. Also when ac is on car is so sluggish in performance and pick up response. I visited service workshop vw mount road in Chennai for four times where car was serviced one month ago. But they say it's normal. If it's normal why it was not there before service. Please explain.

Hi Friends,

I was driving to office this morning in my Verna (2012 Fluidic VTVT SX) and when I was approaching a familiar speed bump, I slowed down as I usually do to avoid any scraping of this low slung car.There was nothing unusual in my driving and the road was also clear of any objects. This was an unscientific bump so one really needs to slow down, specially in a car like Verna. Also I had just crossed one 300 metres back, so you can imagine that could not be doing anything more than a 3rd gear speed.

Somewhere between front wheels just approaching the bump and descending the bump, there was a grinding noise from the underbody - lasted 2-3 seconds, or may be just 2 seconds.
The sound was like some metal tangled with underbody and was now grinding against the road.I am sure the road was perfectly clear. I slowed down to the road side, parked and checked for any underbody damage - could not see any. Nothing on the road behind as well.
Got in, and started driving slowly with eye on temperature gauge and reached office without any further noise or any other issue.

Any idea what this noise could be? Could it be the ABS kicking in? I am told ABS makes scary noise when it kicks in.But I have no experience with that and this is the first time it happened to my car in 28k kms.

Sorry, but could not notice if there was any additional light on console in those 2-3 seconds.

Additional Info: The car was serviced in March 2015 and front brake pads were changed but no issues in last 4 months.

Thanks!

sudev · 5th August 2015, 14:45

Not clear if the noise was associated while the car was clearing the bump or afterwards.

If former then it is to do with lesser ground clearance. Since you have done this road often first check tyre pressure. Is it lower than norm? Check boot or car cabin for any extra weight. If nothing pans out then serious issues like leaked or weak shocks come into play. It could also be exhaust hanging lower than usual due to broken or unhooked mount.

Definitely does not sound like ABS

An intermittent noise like a metallic grating sound that appears from the rear right of my Innova vx 2009.
Happens only when the car is in motion.
Happens mostly in 1st , or 2nd gears - sometimes in 3rd, and rarely (but not unknown) in 4th or 5th.

The wheel was removed and the brake drum checked for stones. While this was on, the prop shaft was checked if any stones were lodged there.
Nothing turned up.

One minor observation, it started after the stepney was put back following a puncture.
But there does not seem to be anything obvious wrong in the mechanism that releases or tightens the stepney.

Rodie09 · 5th August 2015, 14:59

Thanks Sudev for the prompt reply. I'll check for the points you have mentioned. I had checked underbody at the time of incident but will give another try getting the car on a hydraulic lift. Will also get it checked at my FNG.

Guys.
I have a sound coming from the front of my Swift diesel ZDI, which sounds like "Dak, Dak". it comes whenever the car goes over any humps or undulations on the road. Took it to the service center (maruti) Bangalore and they checked it , but really couldn't nail it down for sure- they have tightened the suspension, and so on. and they suspect it to be coming from the steering assembly ?. The car has done 37000 km.The sound is quite annoying and i'm a bit scared to take this car out for a long drive that is coming up in a week. The service center guys say there is no safety risk , but then i'm not keen to take any espcially for a 700km drive with my family in it on the highways. have any of you faced a similar issue - any pointers on how this was fixed would be helpful. I'm planning to take the vehicle again to the SS , some knowledge on the possibilites will be of help- thanks

Check the suspension mounts or lower arms and the bushes for front suspension plus steering.

If it does well then you can take it for long drives. Shouldn't be a problem but be careful on undulations and humps.

Get the stabilizer link rods checked. Remove the rods from both the sides and take a test drive. If the noise is from the rods then there is no safety risk.

Also, raise the front end and check for play in outer tie-rods and lower ball joints.

Today, I parked the car near to my workplace and since it is a bit rainy, there was a lot of slough as the roads are all broken there. When I came back and started the car & tried to move forward, it felt like the rear wheels are stuck. I tried to move forcibly in 1st gear and it moved forward after a lot of sounds(like it is stuck in stones or something is breaking in the rear wheel).

Since then, my handbrake is lifting more than usual and is not that tight. I am hearing some sound from the rear.
Also, the car is behaving strangely since, like for one second all the power vanishes and gets back to life on its own. This has happened twice on my drive from office to home (40kms).

What could be the problem? I'll be visiting my FNG tomorrow. The car in question is a 2008 Chevrolet Aveo 1.4 LS Limited Edition.
