Do you have remote central locking with auto arming? And hope its not the locks engaging and disengaging?

First, please take your car to Fiat-Tata Authorized Service Center & get it checked!

Avoid going to a local garage for such issues, as most of them are not well-versed with Fiat cars!

Palio has some in built safety features like (a) double crank prevention and (b) fuel supply cut off in case of accident. Because of the former, you cannot crank the engine more than once. Every time you want to start your vehicle, you have to switch off and switch on - the clicking primes the engine - wait for the MPFI indicator to go off before you start the vehicle. The latter is a switch located on the passenger side which trips in case of an accident - unless it is reset, the engine will not run. Refer your user manual for this. My experience with Palio (1.2 ELX NV for four years) is there are some gremlins with the electrics. May be the clicks are from the fuel pump - I agree with finneyp and my advise too would be go to a authorised dealer and get the vehicle checked. Hope you are able to resolve the issue quickly and without much trouble and cost!

Default guys save me ......

Guys I am really overwhelmed by your immediate response thanks a lot guys. The story starts like this. I bought this car one and half year back for 2 lakhs then the car had done only 27000 used by a doctor. After which till now I have used the car for another 10k kms. So far I never had any problem in my car and I really loved the car….. Its giving me an mileage of 12KMPL. I had a mechanic who was from sundaram motors( fiat dealer bfor TATA) Chennai and he was having his own garage. He comes to my home for servicing and services the vehicle and I found it comfortable since I don’t have to go to the service centre since it was 35 kms from my home.

Once when he came for servicing he said there is this timing belt bearing is wornout because of which there is some noise and TD sensor also has to be changed because there is some problem because of it and said would cost me 1,800/- . I said go ahead and change it and I don’t want the car to broke down in the middle of the road. He asked me to use the car just like that for a couple of days and he would change the spare as well.

I was on a drive to ECR road. while coming back the vehicle broke down on the way back home. I called him he said the problem is with TD sensor and asked me to try starting the vehicle. The vehicle switched on but their was this click(similar to ECU ) noise from the bonnet. The clicking sound was contious all the way back home and I managed reaching back home.

Next day the mechanic came and changed the bearing and TD sensor. After which also the clicking noise was continuous and he said its some loose contact in the wiring and tried fixing it , but of no help. In the end after long hours of fiddling he said the problem is now with key block inside the car and that needs to be changed which was 2000/- and changed it as well. This time the car didn’t even switch on. Again after an hour of fiddling the vehicle started and went for a test drive now the vehicle broke down in 2 kms. Again the fiddling started this time he said whatever the TD sensor which he changed itself was defective and he changed it to my old TD sensor and the vehicle started. He said the problem is solved and charged me 3000/- for that night.

The next day while I was on my way to church the vehicle broke down in the middle of the road and the mechanic again came. Now this time he said the problem is with ECU and he brought another spare ECU from his friend. When he changed the ECU the car switched on. And he concluded that the ECU is the problem he said that I wont insist on money now and asked me to use the car for an week. I had used the car for about 100 Kms with no problem. After which he came and took 7000/- for that second hand ECU.

In again in another two days again the same clicking noise. This time I took it to CONCORDE TATA in Chennai and gave it for checking the ECU. He said this is an error code from the car and due to frequent change of ECU. He said it needs to be connected in the examiner and to be checked after 3 days they called back saying the car is ready with a bill amount of 1200/- ( they charge 300 RS for one hour in that examiner). I took the car back from CONCORDE motors and their wasn’t any problem for another 150 KMS and yesterday night when I tried taking the car the same problem.

I really lost my sleep guys. I am not able to concentrate on anything. Thought its not such an costly car. This is my first ever car on my own earnings. I am really not able to accept the kind of day light robbery that these mechanics do for their incompetent job.

I am completely lost guys now looking for your inputs to put back my dream vehicle back on road… plssss help me


@ Jaagu :- I don’t have remote locking in the car

@ finneyp:- The last checkup was with CONCORD TATA service centre

@ Deep gautam :- the clicking noise is not every time and comes occasionally and I am able to move the car.

@ VR Prabhu :- I don’t know about the double crank protection. But I am able to switch on the car. I wait till the MPFI indicator to log off and start the car. Once the car is started and engine in running the clicking noise is their. Even if the vehicle engine is not switched on the clicking noise arises.

I suggest you take the car back to Concorde and get it resolved since they are the last one to work on the car and seems to have proper tools to diagnose the fault.

Apart from the clicking sound what are the other symptoms? Did the car switch off when it broke down while on ECR? Or is it you couldnt start it once the engine was switched off?

To resolve, first thing you can do is identify where exactly the sound is coming from. Did anyone check your fuel filter and fuel pump during this period?

@ jaggu:- Personally i am not able to find out where the noise is coming from and no one has checked the fuel pump or anything. they have been fidling only around electricals.

Cant really comment since you are unable to locate the source of the noise. Just check for any loose/worn out belts. Re check the bearing your mechanic said he changed. Probably thats creating the noise. Check if the noise is coming from the fuse box you woud find towards the below right of your steering. If its from there it could be some spark/loose contact. Keep us updated.

Hi Rosario,
It should be definately electrical problem. Please check with all the relays on board. One of the relay should be kaput. The clicking sound comes with only the relays. You have many relays in your car. it could be the ECU main relay or the spark plug relays or the starter relay, etc, etc. There could also be loose contacts with the battery and the relays. hence sometimes these relays work and sometimes will not. Make sure your battery is also in good condition and also check the battery terminals. ECU also does the relay monitoring, and will store the FAULT code in case of engine shutoff.

Rosario,
Things like this should not make you lose your sleep - you are definitely showing signs of aggrieved palio lover!!

First things first - with due courtesy to your mechanic friend, he appears to be all at sea with the electrics. As far as I am aware, electrics in an automobile is a specialised field and any one trying to put his hands therein should be qualified.

I agree with star_aqua that the relays could be causing the noise and the dealer also pointed out the mapping errors of ECU. Where is the original ECU which was in the car? And have you ever had the car washed with the bonnet open? Even a little water in ECU will play havoc.

If you have the time, you can try this just to ensure that ECU is fine, and the problem is in the electricals.
1. Open the bonnet and disconnect both the battery terminals.
2. Wait for about 5 minutes
3. Reconnect the battery and start the engine. Check whether all the tell tale lights function normally.
4. Let the car idle for 3 - 4 minutes, or better still, just have a small round for 5 minutes driving normally.
5. Switch off the engine and once again disconnect the battery terminals.
6. Wait for 5 minutes and then reconnect the battery terminals.
7. Restart the car - and check whether it runs smoothly.

What happens when the battery is disconnected that the ECU will revert to default settings. After restarting, it will start collecting data again, and if there is any major problem it should shut down. If the car runs normally even after the 2nd time after disconnecting the terminals, nothing is wrong with the ECU. And when the car is idling you can open the bonnet just to confirm that the clicking sound is not coming from the ECU.

The downsides to this operation are (a) if you had done a remap of your ECU, those settings will be lost; (b) dealer will not be able to "read" the ECU for any error. So, if you have the original ECU still with you, you can try this out.

Are there any BOSCH service centers in Chennai - you can try for service there, if you feel that you are being taken for a ride. I agree that TATA FIAT is expensive (only if you compare it to Maruti or Hyundai). (I have shelled out 130 bucks are labour charges for wiper setting and 80 bucks for headlight setting!)

Thanks Guys for your replies and i apologize that i wasnt able to reply you immediately as i was not in town for 3 days. i dont know whether is their any boschs service centre here in chennai.
i have the old ECU with me and i would really try doing what you said.
i didnt do any water wash with the bonnet open ( i wash my car on my own i dont outsource it )

As i mentioned earlier in the post. i started having this problem while i was returning back home. where in i had a big bump on the road and when i came over it my underbody of the car dashed against it. can it any way create a problem of this sort ?

because when i started the vehicle yesterday their wasnt any problem and i went for a drive for almost 10 kms.
