I haven't seen the battery but wanted to know if owners could throw some light on this. Never heard of such an unusual battery, and nothing on the Zest thread either.

The car was serviced in June and TASS never mentioned that the battery was weak. They were also quite unhelpful when the car died, just gave the toll free number and asked my Father in law to call them. Tata toll free customer care has a long way to go to become customer friendly because they gave the number for the local Tata commercial vehicle A.S.C, who in turn redirected my FiL to Bosch. Bosch never turned up and he waited until late in the evening, so the car had to be left there overnight & jump started the next day.

Emails to Tata are a waste of time and frankly I'm at the point where I'm scared to recommend Tata. The car is great, no problems, but the rest of the folk are a nightmare.

Recently replaced my petrol zest battery from a local shop. Called him up and he asked me about pole positions. Installing was bit difficult as Tata has clamped some cables together. We had to loosen it up so that the cable could fit properly

Just got the fourth year servicing done at Concorde Patparganj Delhi. It cost me ₹9000 which in my opinion is way too much. The Service manager told me that the fourth year service is expensive.

Can someone confirm this?

Is your Zest Diesel or Petrol? For 90 h.p Diesel, i remember that timing chain is scheduled to be replaced at 60k kms/4 years.

But anyways, 9k sounds less if timing chain is replaced. If you can post a copy of your bill, that would give idea on big ticket items.

Timing chain, in case of diesel 90 hp, needs to be changed at 60,000 km. I am not sure about the year wise calculation though mine had completed 4 years 3 months ago.

Here's the Bill, no timing chain was replaced..

Looks like you could have saved around 1200₹ on the wheel alignment and balancing and another 1400₹ on the Bardahl treatment items, which would have brought the bill down to around 6400₹.

Not excessive in my opinion, but I'm not aware of the service costs for a diesel Zest so cannot say for sure.

As an aside, you should check the service manual for scheduled preventive maintenance replacement parts and have them stick to those.

It was jerking more than usual, and appeared rather strained. When I restarted once, the idling was <800rpm, and flooring the pedal did not do anything. After a few more tries, it was back to it's jerky/ strained normal. I drove it to the closest ASC. I have not heard back much from them. They changed the spark plug cables. But the jerks persisted. I'm gathering what intelligence I can get from other Zest owners. Did the ECU updates solve the problem for you? Thanks in advance.

Hello,

Yes, after the ECU update the problem has disappeared. I would also like to ask if you are quite hard on the acceleration. Cause over the 50K run of my Zest i have found, when you try and push hard, specially in Eco mode, sometimes that jerk issue does arise.Again this might be a temp issue, and may be something only i have faced.

Get your ECU updated. That might solve it.

Regards,
Devyaani.

Absolutely right! Balancing and alignment is best done at a specialised shop. You would save some cost as well in the process.

Item no 14 & 15 are absolutely unnecessary. Could have been avoided. Service Advisers are known to include such things to jack up the bill and as a customer you should be aware of this and take your own stand. Not sure about item no 2 which appears to be engine flush.

I think your's is a petrol version, going purely by the fuel filter cost. Can you please confirm?

Agree with you and VeluM on the unnecessary additions part. About Rs.6500 is nominal (similar to what I spend on my Petrol Zest).

I think his (devilicious) is a Petrol Zest.
Engine Oil required for Petrol and Diesel are 4.0 and 3.2 liters, respectively. His bill shows 4.5 liters.

Also, coolant required for Petrol and Diesel are 6.0 and 7.5 liters, respectively. His bill shows 5 liters in total.

Yes even we faced this issue where there was loss of power and significant drop in mileage. An ECU update was done. The engine no longer feels strained and acceleration is very good. The car performs well even in Eco mode now.

Doing the ECU update alone unfortunately did not work. They changed the lambda sensor to check if that was causing problems. It wasn't, the jerks persisted. Finally, they changed the fuel pump and all is mostly smooth again. I never floored the pedal. Nor do the car's other drivers. So it seems to be the fuel pump that was the centre of the problem. I'm not sure if this is related or is a tuning issue but the idling is now at about 600rpm. For a petrol engine, it should be about 850-900rpm.

I think wheel alignment was necessary as the car was vibrating at higher speeds. I thought what better place for realignment if not service center.

Yes, it is Petrol Zest.

Hello Guys,

So my Zest quadrajet has completed almost 66k and its time for changing the tyres. There is still some tread left but I can feel a drop in the performance of the vehicle (major tyre noise, braking is not confidence inspiring, turning and what not).

Did a wheel balancing yesterday and the adviser also recommended to change the tyres. So my question is which one should I go to, presently being Bridgstone B250. I did a couple of calls yesterday to get some quotes and here are my findings in order of preference:

1. Bridgestone B290 : A good upgrade over the existing B250s - 4650/- (Darshan Tyres - Solapur rd, Pune)

2. Yokohama Earth1 : A nice overall stable tyre and has good reviews on the TBHP - 4600/- (Lonkar Tyres - Kondhwa, Pune)

3. Continental ccc5 : Don't know much would like some inputs - 4400/- (Darshan Tyres - Solapur rd, Pune)

4. Bridgestone Ecopia : Heard it is mainly good only for better fuel economy, otherwise an average tyre. I am not much inclined towards it, but again some positive feedback would be welcome - 4600/-

My daily run is almost 70km (Kondhwa to Hinjawadi) mostly highway.
My requirements are : Low tyre noise, Good braking in both dry and wet (mostly wet, can compromise little on dry), better handling.

Good to have : Fuel economy.

I am not planning to change or upgrade from my existing 185/60 R15's but again any experience and feedback would be welcome.

You can try Michelin XM series. I have been using the same in my Vista for the last 30,000kms and it has performed well. Good grip, specially in wet, low noise and even wear & tear and very good air retention capabilities.
My run is almost similar to yours: 65 odd daily kilometres, 60%-40% split between highway and the urban crawl.

Yes, Michelin's are expensive. But i personally feel, the premium is well spent.

Thanks for the feedback.
Yes, I did get the quote for Michelin as well but kept it aside as a safe bet if i didn't like or get any other good suggestions. They are costing me around 5500/-.
Lets see I still have a couple of weeks to explore and research.
