Had very bad experience at my 4th service in Neyveli. Every time they used to gift me different scratches in my car but now they had something different for me. They have spilled battery acid all over my battery tray and they returned my vehicle without even cleaning it. I noticed it in the service centre itself and asked them to clean it. But they didn't clean that too properly. Anyone else tip me how to clean it
Hello Arun,
Take your car to the battery shop you know or known to friends, carry a bottle of diesel, let them remove the battery and clean it thoroughly, after which take it to your regular car wash, and repeat with water and soap shampoo, take care not to spray water on electronic in the engine bay.
Hope this helps.

Hi ,
Actually I cleaned myself with baking soda and some diy methods but it's of no use. I raised a complaint in TMSC app and mailed them about the service. As a solution the service centre guys cleaned and painted the parts where rust formed.

Tiago has crossed 50K milestone on 21-Oct which is 1236 days since D day. This is roughly 40 Km per day / 1250 Km per month, which is way more than what I calculated before buying a petrol car.

Since 50K is a special number, I have a gift for this little guy which was running at the back of my head for quite a few months:

Sourced this awesome looking pair of Tigor XZ+ / JTP headlights from boodmo for ~10K. I have to ask around few shops who can do it the right way as it is not a direct lift and drop upgrade. Will update here after completing the installation. Until then, its bye from:

Headlight Upgrade
018 Front Left.jpg

Parts:
Headlights were sourced online from boodmo.com and arrived within 10 days via Fedex shipping. Kudos to boodmo for quick shipping and prompt response when I had to contact support for a payment issue. Below are the part numbers if anyone is interested. There are a couple of styles available with slight changes in design.

Style 1 - Chrome on top of headlight assembly and all black inside. This is the one used by the DIY author Dr Aniketh on his Tiago
Part Numbers: 542554400101 & 542554400102
Style 2 - This has chrome bezels inside for projector but all black on the top. I liked all black top and also cheaper by 2K so I chose this one.
Part Numbers: 542554400126 & 542554400127
Style 3 - Used in current gen Tiago XZ+ variants. This looks almost same as Style 1 but yet to be listed in boodmo for confirmed part numbers.
Part Numbers: Unkown for now

Installation:
So I asked Tata ASC first for headlights installation but they had not done such a retrofit before and were not confident with this work (as usual). Next I asked a couple of car decor shops who quoted north of ₹1000 which did not seem to be a fair price. I then turned to a nearby FNG who redirected me to an auto electrical shop on the way to my daily office commute. Those guys undertake only electrical work for vehicles of all kinds (cars, trucks, buses and so on). They did the installation for a mere ₹300 and the workmanship was very good and nowhere below ASC's quality levels.

This new headlight assembly is a straight fit and no changes are required to mounting them on a Tiago. Even the primary power connector is same and works out of the box. The only incompatibility is with the height adjustment motor pin which is different in new assembly compared to my car's wiring harness. I will check scrap part shops and source them for this to work. Until then I cannot adjust the height of light throw using the headlight stalk below steering wheel.

Another difference is stock setup turns off low beam when high beam is ON. This means in new assembly, when high beam is turned ON, the low beam projector will turn OFF. There is a quick mod mentioned in above post to get both the bulbs glowing at high beam by using a relay. I am however fine with the way it works by default and deferred this later if I really needed both lights for night driving.

Parts Cost: ₹10,200/-
Installation Cost: ₹300/-
Leveler Connector: Probably 100 to 200

Height adjusment motor connector does not match with Tiago's harness. Gonna hunt scrap market for a matching male connector pair:

Quick Test on a wall revealed RHS is higher than LHS and needs to be aligned properly. Also did a test run at night only to know that even low beams are at a higher spot, just enough to blind oncoming drivers. Should align the headlights first even before sorting out leveler connector:
