    Hi..Iam newbie here and thiss my first post.I drive a pre owned 2009 LINEA MJD dynamic with 70,000 kms on the odo.Soon after i got delivery 3 months ago i took the car to the nearest TATA-FIAT service centre and checked the service history.I found out that the previous owner had replaced the timing chain/belt at 45k to cure ''Excessive engine noise''(RF motors kochi website)and after that the car had never seen a proper Fiat service outlet.I changed the lubricants (shell 5w-40) and all filters the same day from another garage since the TASS had no recommended lube or filters in stock.The odo was 67,400 then.
    After the above rituals i took the car home.The windows were down and i switched on the Ac and got the windows up.It was night and pretty silent around and i felt like there was a helicopter hovering around far away.I accelerated and the sound increased and by the time the rpm was 2500 i felt like a diesel ape three wheeler was escorting me.The sound though not very loud is very annoying.It decreases when the foot is off the gas pedal.The sound cuts down drastically when the windows are down.I have driven the car almost 4000 kilometers after this.The mechanic who changed the lube advised that the clatter or thuk thuk thuk thuk (my 3 year old daughters lingo) is due to water in diesel and adding a litre of lube for a tankful of diesel would solve the issue...which i did..and the sound is still there.Can someone throw some light??:confused1

    Get your car checked at FASS dealers. I am sure the problem should be with the filters else get the belts changed again.

    Is the noise on the move or while the car is stationary also?
    Try revving till 2500 when car is stationary and check if you still hear the noise.

    April 14-paying heed to fellow members,took the car to the spanking new Hyson motors showroom @ Trissur .the showroom and service bay are stunning to put it lightly.Mr.Madhu,the advisor was prompt and straight talking.We went for a drive and he agreed with me regarding the noise.time was 10 am and 3 lineas had already lined up before mycacofonix.
    I returned to pick up the car by 5 in the evening and a hefty Rs.10063 bill was waiting.The noise,as expected,was still there.Madhu shook his good looking bald head in despair when i asked for a cure.So here iam..Driving the loudest fiat in town..anybody wants a competition for maximum cabin noise..PM me

    After many visits to different garages in and around palakkad and kovai,one avid auto magazine reader from the neighborhood
    aged 17 has diagnosed the illness.I need to replace the 'tensioner belt assembly'.I talked to the Thrissur FASS service engineer and he immediately agreed to it.To think he drove my car for many a miles and came out shaking his head:confused.Many multijet drivers who experienced similar annoyances around the world (http://www.justanswer.com/uk-car/7f...xx-fiat-grande-punto-1-3-diesel-multijet.html) have found different pulleys to be the culprit it seems.

    Get your injectors check bro,if that is kadd kadd and some knocking sound from the engine then ask TASS/FASS to put new injectors and give a try .I did get my injectors changed.
