Hi Folks,

Facing the following issue regarding the Zest 90 BHP QJet-

1. Low End pickup is quite bad. Engine takes a while to reach 2500 rpm post which the turbo kicks in and things get better. If the RPMs drop below 2500 in any gear, subsequent acceleration is lethargic. This is especially bad in ghat regions or with a full load of passengers and I have to downshift to 1st or 2nd to get any meaningful acceleration out of the vehicle.

2. At constant throttle inputs on the highway, the car doesn't maintain a constant RPM. There are quite obvious fluctuations in rpm like the car is momentarily gasping for breath.

3. Mileage I'm getting as per the MID is 15 kmpl in the city and 18 on the highways with a full load of passemgers. I feel this is a tad bit on the lower side and is a result of the constant downshifts I have to do because of #1.

I got the vehicle recently serviced with oil/diesel and air filters, engine oil, coolant etc. replaced at a FNG in Wakad (Pune).

During service, water was found in the diesel filter and hence it was replaced. Issues #1 and #2 haven't been solved though.

The FNG further recommends an EGR clean and maybe a look at the MAP sensor.

Car in question is a 2015 model with only 54xxx km on the odo which I recently purchased used. The issue is not with the clutch as reconfirmed by my FNG.

Has anyone using the diesel Zest (or any of the 90 PS VGT Multijets for that matter) experienced the above symptoms? Will an EGR clean solve these problems?

Also, how much of a hit to the wallet am I looking for should the EGR clean up be done at the TATA ASC vs an FNG?

Finally, it would be helpful if someone could suggest where in/around Pimpri I should get the vehicle looked at.

Hi all,

I am in a dilemma that I would like to clear with the help of respected forum members.

I own a Tata Zest 2015 diesel which has done around 70k km up until now, the car is in excellent mechanical condition though the same cannot be said about some electrical components ( steering controls & headlights have started to show their age now) & exterior.

Recently, when I went to the TASS in Lucknow to get the timing belt changed & an ECU update too because of gruff engine & very low average, the SA told me that since the model is long out of production company has stopped sending updates & if we do it there is a chance of frying up the ECU. Kindly, throw some light whether this is true or not because I highly doubt that its true.

Secondly, I am thinking of selling it now, what would be the appropriate price to ask for, its a 2015 XM model in white colour.

Thanks a lot.

Thanks to Projnesh Biswas for sending this information in. Heartfelt gratitude for sharing it with other enthusiasts via this Team-BHP share page!

The part is called the compression spring for the seat.

Details of the parts can be found here:
https://boodmo.com/catalog/part-assy...seat-33011579/
Part number: 287191010140

If you wish to search on Boodmo, use the term “Tiago” instead of “Zest”.

It's a DIY job. I have done it recently.

Hope this helps.

Thank you very much, Mr. Projnesh and Aditya for finding this part.

As per a few discussions at service centres here in Bangalore, seat base replacement was the only option. Even Zest's OEM catalogue does not mention this part separately.

I will order this and will see if I can unbolt the seat at home, otherwise I will get the help of FNG.



In another event, a horse jumped on my car outside Gol Gumbaz, Bijapur and broke my left rear view mirror. The plastic mount was broken, but the whole mirror and casing were intact. I had to remove the mirror from its dangling position and drive to Bangalore.

The body shop manager at Tata ASC estimated 8K but the actual price of the whole unit was Rs 2200. They charged 650 for the simple task of mounting the mirror on the door.*
I could have done it myself or fixed it at an outside garage for 100 rupees, but I wanted to get the mirror fixed there itself as it was very difficult to drive without one.

Body color cowl of old mirror was useful as new mirror came with black cowl.
I have the old mirror lying around, every thing works except the plastic mounting

This went on for few months,and later while switching on it was mute some times. Switching off the car for 10-15 min and restarting would solve the issue. Then one fine morning, power steering was not working. Shown at TASS, and they replaced the battery.Since then all issues were solved. I have opted for a higher AH battery

For me, navigation doens't work for 2 years now, and if USB drive is plugged in, it hangs and except answering calls nothing else works. No buttons on the ICE works. When i pull out USB drive and Micro SD card, it suddenly starts working and keeps working even if i re-insert both of them till i switch off for a few hours. No issues if USB drive was not connected when starting up.
Then cycle repeats. It took me some time to understand and work around. The battery is now 4 years old. Amaron battery

1. Check the wastegate vacuum solenoid mostly it would be working intermittently. Also check its plumbing and vacuum tank.
2. Clean the EGR, Intercooler, check all the hose pipes connecting to the air intake.

If the vacuum solenoid is gone it can replaced with Ertiga's (direct fit & half price).

Thanks a lot.

I recently bought a 2015 XM Quadrajet via dealer which had run just 50k on the odo. Cost me 4L with transfer.

OLX throws anywhere between 3.5 to 4.5L for this model.

Cars24 will quote you a measly 3L.

Hope this helps.
