Is it any better if the car is restarted ? or Slowed down/RPM lowered ?

Answer from my friend are below:


>>Was there any diagnosis attempted by the TASS/Other ?
No, I actually need to take my car for servicing and wanted to get this issue checked. But I will check with this forum first so that I can talk to them better informed.

>>Clutch Cable, Oil ?
Got the Clutch Cable replaced during last servicing

>>Any other symptoms ? Black Smoke , Clutch slipping ? Any specific Gears ?
Yes, I observed Clutch slipping few times, specially when climbing steep slopes.

I have changed the compressor & Ac cut out relay, yet the problem persists. Please suggest the remedy.

Hi everyone , finally i have found the solution for this problem which is a non working ac thermostat which is a long aluminium wire type thermostat or you can say a mechanical thermostat, which is located under the dashboard and the long aluminium wire is inserted in the plastic box containing the evaporator coil through a small hole in the plastic box. The kerr kerr sound used to come when there was ice formation on the coil and still the compressor would not cut off. It has been almost 2 months since I replaced the thermostat and the sound has not appeared.

I have a Oct 2006 Indica DLG Turbo. It has been a trouble free ride of over 60k in all these years, but off late, it is showing signs of ageing. When i start my car in the afternoon for the first time, it used to start at half a crank to one crank.. now a days, it takes more than 5-6cranks at a stretch to start. I also see a puff of smoke come out when it eventually does start. The battery is a new one, so that problem is ruled out. The dynamo was recently serviced, so that is also not the problem. The alternator was also cahnged recently and after all of these changes, I did not observe this problem.

Once the car starts, the check engine sign comes on and stays put for another 3-5 minutes and then goes off on its own and doesnt come up again till i stop and start the car again. Please suggest what could be the problem here and also some good electrical shops in Whitefield area of Bangalore is much appreciated.

I have a feeling it could be one of the two issue below.
1. spark plugs (I have not changed them so far), or are they called glow plugs?
2. Starter motor needs servicing.

I always wait till the heat coil light to go off, and atleast switch on and off 3 times before starting the car and wait for a minute before moving or switching off the car.

You are correct. The problem should be with the glow plugs or the glow plug timer. The glow plugs and the timer are controlled through the ECU. The glow plugs are on even after the engine starts. This is known as the post heating. I am attaching a pic of the glow plug timer with this post. Also make sure that you put in the timer as per the part number as there is a difference between the timers on the Bharat Stage II and Stage III vehicles.

And yes this could be the reason for the late start of your vehicle as well as the glows plugs do not get hot at all if the timer is dead.

The glow plug timer is located just behind the battery. The cost of it should be around 600-800.

dass, Spark plugs are in petrol cars whereas diesel cars have glow plugs (GPs). The spark plugs work (produce the spark) for the whole duration while the engine is running, where as the glow plugs, become red hot & increase the cylinder head temperature only during the start of the engine.

Since you need 5-6 cranks to start the engine, it means that one or more GPs might have failed. The smoke is from the unburnt gases that are exhausted, as the cylinder temperature is not sufficient to ignite them due to the failed GPs. Since your car is 6 years old & run 60K kms, failure of GPs is not an uncommon thing. I had replaced my first GP after 5 years (car had run 56K kms). That served me well for over a year & then my balance 3 GPs failed @ 80K kms (6+ years). It was then that I decided to replace the full set of 4 GPs, Beru make costing Rs 1400/- & Rs 80 labour charge (Rs 20 per GP) from nearly Lucas TVS. Since then I don't have any starting trouble.

CRDIsamir, I doubt if there is any issue with the GP timer. dass you can check that yourself. When you get inside your car, stich ON the cabin lamp. When you turn the key to ignition position, the cabin lamp dims (due to the voltage drop as the GPs draw good amount of current). The coil symbol on the dash lights up. When the coil symbol from the dash vanishes, it means there is enough temperature in the cylinder heads to start the car (compression ignition of diesel). However the cabin lamp would still be dimmed, which indicates that the GPs are still drawing current. This may continue for 7-10 seconds depending on the engine temperature & the ambient temperature. When the cabin lamp turns to its normal brightness, it means the supply to the GPs has been cut off. Why I explained you this to you is so that you can check if your GP timer is working fine. If your cabin light remains dimmed for 7-10 seconds after the coil symbol on your dash vanishes, them your GP timer is working fine.

The Check Engine should not light up if the Glow Plugs have gone. The Check Engine lights up only if the timer is not working. In the Bharat Stage III vehicles there is a post heating function in the timer. meaning the glow plugs continue heating even when the engine starts unless the specified temperature is attained. Now if this fails untill the sufficient temperature is attained by driving the vehicle after which the ECU signals the timer to stop heating. So the Check Engine stops glowing after 5 - 10 minutes of engine running.

In CRDI & Dicor engines all the 4 glow plugs are controlled through the ECU hence you get the service / Check Engine light if any og the Glow Plugs go

Coolant gushing out of Resorvior Tank on my indica when hot, is it the head gasket?

Did you try to open the coolant tank cap when the engine was very hot? If yes then what you have experienced is quite common. In fact there is a warning in the car manual "Never remove the cap from the coolant reservoir when the engine is hot", as the coolant is boiling hot & likely to gush out.

If your coolant level is depleting & there are no obvious coolant leakage signs (e.g. coolant drops on your garage floor), only then there is a possibility that the coolant might be leaking through the head gasket)

Coolant is found leaking from the Coolant reservoir cap only when the vehicle is back from a trip where in the fan kicked in several times, coolant is found leaking from the cap!

Either a) Cap needs to be replaced.
Or b) Coolant quality is down. Did anyone add water ?
Or c) Engine is overheating. Check with TASS. Pump not working. Fan not kicking in early. Etc

Please suggest some good auto electrical workshops near the whitefield area.. Else where do i find the nearest Lucas TVS workshop in Bangalore?

Thank you for the detailed explanation.. I always used to wonder what the difference between the two were.. This really does help me understand.

I now believe that it may be the GP which might have gone kaput. I had gone out of country for 3 weeks during which the car was elft unused and that is when the problems surfaced. I will get them checked at the earliest.

What do you suggest I do about the check engine problem? It only stays for few minutes and then doesnt return til the time I restart the car.

here you go. not very close, but I suppose you'll have to manage!

Besides what CRDISamir has suggested @ GP timer, have you off late checked your engine oil level. Is it between the 2 marks (max & min) on the oil dip stick?

I have a 2009 Vista TDi. My First Diesel. A week after i bought the car my family and I went for a short trip about 170 kms. I checked the mileage then using the Full tank to Full tank method. I got an Amazing 22.7 kmpl!! As the months rolled on I kept getting lower and lower figures. It now stands at a sad 13.5kmpl! I always drive with the AC on. I flick it off when before going up inclines and overtaking.Sports Mode! I do stomp on the gas once in while. But generally no rash driving or frequent braking. I use longer smoother routes and generally avoid city traffic.
Services are regular. when pointed out to the TATA guys here even they have not been able to do anything much. Now reading a few other posts here i find QJD's giving lows as 9-10. I guess these TATA guys think i am better off. Am thinking of heading to Belgaum to get my Vista checked up there. Anything points/tips that could help me out would be welcome.
