Congrats on your new buy. I believe, there is no thermostat setting which you can do manually. All you have to control is the blower speed and turn ON the compressor. As a result the logic to cut-in & cut-off the compressor is solely dependent on the blower speed positions and the actual temperature inside the cabin.
Try running the blower set in position 2, I hope the cabin wont be deprived of cool air.
In any modern car, the Engine management system will cut-off the AC compressor while the drive floors the pedal suddenly. This is not just specific to Nano alone.

My Nano is having an odd behaviour of power loss at times in the 3rd gear. It kind of feels like the clutch is slipping or as if the petrol flow got cut off when driving in 3rd gear. This happens only occasionaly. The car has run for about 800km so far. There are no such issues in any other gear. Any insights into the possible causes ? The first service is due in 1500km, but I want to get feedback from fellow Bhp-ians before I meet the SA.

I got the fuel tank full yesterday and it seems to be starting up fine since then.

Btw, I did ask my relative about the workshop and they have no idea about that. What it was all about?

if it was silent then definitely some loose connection.

there was a major recall of all nanos. Mine is a new bs4 version, it was even called.

Why dont't you register a formal complaint on tata motors/nano website and get your car checked.

Let me point out a big difference in visiting a Tata Motors service center and registering a complaint. When you do the latter the company takes note of the complaint and it gets stored in their databased + they usually follow up with you on your satisfaction with their resolution.

Trust me Tata guys have done a great job with all such complaints. I own a Vista and my cousin owns a Nano and we've noted the difference.

The speed of blower of my Nano, sometimes suddenly reduces. For e.g. I am running blower on speed 3 but sometimes the air flow is like the blower is running on 1st speed (when the knob is still at 3rd speed) it continues like this for indefinite time and the speed returns to normal when the car is switched off for some half-hour, this problem happens on long drives. I think that the blower is getting heated-up.

Funny. I have yet to experience this 'cut-off' feature, after clocking 16k kms. Is this some new feature introduced in the latest Nano? Mine is a 2012 LX model.

If the vibrations occur only while braking, it might well be the cause. Still, it would be good to get the front brakes checked and cleaned up if needed.

I get this all the time. Nothing to worry. Usually when the level indicator wants to turn one notch lower, from four bars to three bars, it keeps playing between three and four for awhile before settling down to three. I see it all the time. Initially I was worried, now I just live with it.[/quote]

That seems normal. My FE till the first 1000 was around the same. It shot up to about 16 post the first service, and now it's near-20 most of the times.

I hope you aren't trying this after riding over a speedbreaker? What are the speeds you are talking about? It's rather difficult to try and accelerate in the third and fourth gear and that too wthout pedal assistance. I suggest shift down a gear or two and accelerate again back to third-gear speeds, instead of trying to coax the engine to remain in 3rd.

Did you let the engine cool down completely before switching off? Before switching off, always listen for the whine of the radiator fan. It also shows by way of slightly increased vibrations. Once the fan dies out, only then switch off the engine. If you switched off the engine before the fan had died out, you will face starting problems in your next crank. This is a problem with most cars, not just with the Nano.

I noted this behaviour on two very hot days. Once in Bangalore and once in Kerala. I also thought that the blower/cooler reached its limits.But then it happened again on a rainy night.I turned the thermostat to hot air and ran for 2 minutes.The blower air flow increased significantly after that.I think it is because of the icing that happens with humid air.

I faced this problem too and I think this is linked to the electricals also( faulty or inconsistent Fuel pump relay?).

Starter motor Relay?The day after this, I had stopped at an ATM and on returning to the car, I was not able to crank the car (starter was not activating). I had to wait for 5 min and then started again.Again this happened after a nandi hill run.I noticed that this happens only after an extended (5 hrs) slow speed traffic / uphill drive with AC on full time.

Wiper motor relay? : During some night light rain driving,I was driving with the headlights on and flicked the 'on demand' wash and wipe.The wiper refused to budge.I switched the headlights off/on and then it started working.

In all these cases,I am doubting a sticky or weak relay contact or a momentarily weakened battery.

I reported all this to Concorde,dairy circle and lodged a complaint on the Nano website asking them to think about better quality relays and/or upgrading the battery.They said they checked the alternator and starter motor and found no problems. It happened once after that too.
So now I dont switch off at Traffic lights :-(

Other Tbhp nano owners have also faced this problem (for eg.HR06),

Thanks for replying.Yes i tried running it both in 1 and 2 but never in 3.
I will check this in the first service.

No.Infact i need to go to gear 1 after riding over a speed breaker.This car has some weird gear ratios.3rd gear picks up speed only after 40-50kmph.I am still getting used to this.

Thanks for replying.I never know about this stuff.I will keep this in mind.

This problem did not come afterwards..car has touched 500kms so far.

Hello all,

A week ago I gave my car to Balaji Garage for replacing all 4 shock absorbers since the original ones had become rock hard
and the ride harshness was that of a bullock cart! Luckily this was claimed under warranty.( not an easy task, long story behind it)
Since the oil change was also due, I asked for that too.

I picked up the car the same day, and on my way home saw that the "high beam" dipper was not working, nor was the hazard
warning switch. The subsequent day, my check engine light came on while driving to the park and in a few minutes, the
coolant warning and the loud beeping started too. Stopped the car and checked coolant level. Was at a perfect level. Left
the car alone for an hour and drove back home. This time, the check engine light had gone. Went to Balaji again, but had to
wait for 20 minutes till the guy with the scanning tool came out. Also the manager says to me, that connecting the laptop
to the car will cost me Rs.250 and that is payable by me and not covered under warranty. Anyway, the mechanic comes out
with the smaller scanning tool and just my luck, the warning was gone. Mechanic says nothing can be done now.

Same warning next day just when I reached my workplace. Decided to take it to Balaji again. Barely drove a couple of kms
and the engine started juddering. Quickly diverted to Pandit Auto's huge workshop in Bhosari. Last 2 kms were a nightmare. Had to do scary stuff that cannot be repeated on this safety-loving forum :-). For the record, I do my own stunts.

Anyway, the Service Advisor says to me that they can extract the historical data from the ECU and it is not a problem if
the Warning light disappears by the time the mechanic touches the car. Bad news, here they charge much more than Balaji for
the laptop.

They kept the car for 2 days, and concluded that the car needs a new thermostat cover ( SInce they noticed a coolant leak). Both covered under warranty, yet I had to shell out Rs.449 for the laptop diagnosis.

I was there when the laptop was connected to the Nano. It seemed like a very easy to use software with multiple tabs. Each
tab was for a different part of the engine. In my case, the software did not tell us anything that we didn't already know.
The cryptic message was "Check cooling system"or something like that.

Heavy rain in Pune last 2 days. On my drive back home, I drove slowly and carefully through a 6"-8" ( at least) deep pool
of accumulated rain water. After this pool the road was quite empty so increased speed to 40 kmph. Then I remembered my
Enfield's behaviour after pressure washing. So immediately checked my Nano's brakes. What brakes? :-). The drum brakes were
quite useless thanks to the dunking. Pumped the brakes for a bit, but improvement was very gradual. Lesson learnt.

A day of driving, and the AC stopped cooling. Drove back to Pandit who fixed it in 5 mins. They said that it was a blown fuse.

Hello,

this thread is really an eye opener, thanks a lot for all your posts. Already learnt a lot.

I got a second hand Nano LX 2011 (Jan) from a Tata showroom last week and yesterday my speedo was not working anymore. Since there is heavy rain at the moment, I didn't find the right time and place to check where the problem might be.
Does anyone know, how the speedo is connected and where the cable runs through? I guess, it is a mechanical one, right? I could not see anything under the bonnet.

The car is driving very nicely otherwise, only that my left front tyre is half blank. The speedo is showing only 7k, little strange. I read about the alignment problem and the suspension issue and will try to analyse this problem next time in the garage.

I read the Nano manual, but nothing about the speedo.

After reading almost the whole thread, I have the feeling, more than one of you has been under the car with eagle eyes. ;-)

Any help is appreciated
Raju

[john doe]

For a front tyre to go bald within 7 K is very unlikely. Probably the half bald pattern indicates an alignment issue. Should be easy to check for Rs.250/-
Worrisome is how the speedo stopped working. Connected to the odometer, isn't it? So is the 7K figure tampered with?

Can you please share with us what you paid for the LX, so that we all know what our cars are worth in the 2nd hand market?

Not really want to be a party spoiler for you, but I think what John suspects is likely to be true. Though not impossible, but still 7K is too low reading for a used car.
You can use this link to check: http://www.tatamotorsassured.com/ind...l&view=tmasell

Also, the balding of tyres can be an alignment issue, if the tyre was not specifically changed to an older one before the seller handed over the car to you. Suggest you to get the alignment & balancing checked.

Speedometer is most likely to be a bad speedo cable or one that has come out.
