Hi Everyone, I have been happily driving my 6 years old diesel zest until now.

I found this spring loaded object behind driver seat today.
Car was driven last night, all seat adjustment working fine.

I am just wondering if driving car is safe or not in this current condition.

posted this query in Zest forum too

Google lens hasn't helped either(it pointed out a gun muzzle )

Appears to be part of the seat belt pre-tensioner mechanism. Its good to have this inspected.

Thanks for input, I went looking for seat belt pre-tensioner but could not find it.
Sockets were attached to simple metal, no extra hardware is seen on both , driver and passenger seat .

Then I looked under the seat and found that this spring thing is part of height adjustment mechanism.

When we lower the seat height, this gets compressed and when height is increased, this get uncompressed. That's why piston like mechanism, to make it slide during adjustment.



There are two of such things attached to seat frame, Left and right side.

Mine left hand side has broken off, right side still intact so height adjustment still working.


I could not find this part in OEM catalog which is here for front seats.

Arrangement seems serviceable but part is needed and mechanic to do so.

Oh! That's unfortunate, a trip down to JC road probably can help you! Worst case you'll have to make a trip to Shivajinagar and get the whole frame! I dont think this will be covered in insurance!

Hi there,
I found the same part lying in the foot well of my 2015 Zest XT about 2 months back. Seat height adjustment is working fine. Checked my ABC pedals, all good. Now thanks to your post i know where to look. I guessed that this could be from the seat mechanism as it was a very heavy spring. By the way, I only found the spring, not the plastic housing that you posted here. Same yellow position paint markers.

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.

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

Hopefully, I will update this thread soon.
