Hi GTO,

Had a wonderful and swift experience getting the parts.
Thankyou so much for the lead.

Here are some pics of them installed on mine.

Spotted your car the other day - was clicking a photo of my car while waiting to be picked up, and later on while checking the photo out realized the red thar in the background was none other than yours.

Hi GTO, not sure if this ever happened again or if this got resolved, but let me share my experience on this.

I also started getting petrol smell, on occasion, sometime back in March. Initially, it went back on its own, so I did not care much.

However, recently, it started getting more frequent. I noticed that the smell was strong when I had about half or less than half tank full - that meant a lot more sloshing around of petrol in the tank, and lot of evaporation and fumes.

So I went to check with my Service Advisor. I was worried about some fuel leak in the engine bay like @abirnale discovered in his XUV7OO. The service center inspected the cabin bay thoroughly, with me standing next to it, and there was absolutely no leak anywhere there. The engine bay was clean and dry. There was no petrol stain or smell anywhere there. It all looked fine.

They also checked the fuel vapor canister and that was also all fine.

Then they checked the next suspect - the fuel filler lid - and voila, the O-ring in that had gone bad and the seal was poor. Clearly the smell was coming from the fuel cap. It was leaking the vapors. That is why the smell was stronger when fuel tank was half full or less. Lot of sloshing and vapors there in half tank, and those were leaking out from the fuel cap.

I also Googled it and found that a leaking fuel cap is one of the most common sources of fuel smell in the cabin.

The solution was quite simple. They ordered a new fuel lid cap for me (it was not in stock). And once the part arrived, they changed the lid cap. And now the petrol smell is completely gone!

So just wanted to share this simple check and solution with everyone, in case anyone else has petrol smell in cabin, in a Thar.

Am pleasantly surprised that it was a one-off bud (like so many others in the Thar) and hasn't happened again. But thank you for the solution. Who would've thought that the fuel cap will be the culprit?

You didn't get a check engine light ? That's the first tell tale sign for vapor leakages and among one of the most frequent ones. Was OBD plugged-in to generate the fault codes ? Your vehicle’s fuel system is a sealed system designed to trap fuel vapors before they can escape into the atmosphere. When the fuel evaporates inside your fuel tank, the harmful vapors get moved to a charcoal canister. The EVAP system draws in fresh air, gathers up unburned vaporized fuel and delivers them back to the intake system to be re-burned in the engine. Almost same thing is done by PCV valve, waste gases are fed back for combustion in the engine.

Any EVAP leakage from the fuel system (from fuel tank to EVAP canister) will give the "check engine light" first, that's when ECU detects any issue with the EVAP system and generates a trouble fault codes. The fuel caps (a part of the EVAP system) are specifically designed with pressure and vacuum relief valves to prevent the evaporation of fuel. It can be both vented or non vented as per the car design. Even a blocked vent can trigger the "check engine light"

Long time back I had fuel smell in the cabin, which was diagnosed to faulty fuel pump and this was sitting right under the rear seat, in the cabin . I was surprised to see the fuel leaking under the seat when mechanic removed the back seat and the foam was drenched wet with fuel, quite scary situation. Fuel pump had gone kaput and it was such a strange design to put the fuel pump, inside the cabin.

Another thing, how a fuel cap vapor leakage was smelling inside the cabin ? I can understand, google pointing out this, but I cannot comprehend how, since the fueling system is all external to the car.

You are correct that any vapor leakages should have CEL thrown in. However, no, there was absolutely no CEL on the dashboard.

I thought the same at first, and hence never thought that the fuel cap would be the culprit. I was suspecting some leak in the engine bay, which the AC system was sucking in.

However, once the SA said it was the fuel cap, it all became obvious. Then I noticed that just standing outside the car, near the fuel cap area, I could feel the strong smell and the vapors. So clearly there was a noticeable vapor leak there, which was easy to smell outside too, not just inside. Just that I usually get out of the car from the driver's door and walk away to the front, which is the diagonally opposite direction to the fuel cap, and thus never went near the fuel cap from the outside and noticed it. I would have noticed it at the petrol pump when I go to refuel, but there my mind naturally assumed it was the general smell of the air there and never realized this as an anomaly.

Now I am still not sure how the AC system was sucking in that vapor from rear left side back into the cabin, but it was happening for sure.

Here are some articles that mention fuel smell inside cabin due to leaking fuel cap.

Malfunctioning Fuel Cap or EVAP system

There is also a chance the gas smell in your car cabin is because of a faulty gas cap or EVAP (emissions) system. If your vehicle’s gas cap isn’t sealing correctly or is loose, damaged, or missing, gasoline fumes may escape through the fuel filler.

1. Trouble with the Gas Cap

We've saved the best news for last. There's a possibility that the smell in your car is due to nothing more serious than a loose, damaged, or missing gas cap. This cap seals gasoline vapors into your gas tank, so a cap that's not doing its job may stink up your car. A loose gas cap is the easiest to fix: simply screw it in tighter. However, even a cracked or missing gas cap is a quick and inexpensive fix: simply purchase a new gas cap. They don't cost much, and installation couldn't be simpler!

I got this vapor issue on my brand new Thar too. Maybe the jeeps 4th or 5th fuelling. After a tank full, I kept noticing a distinct petrol smell in the car, while driving back home. Initially I thought it was the petrol bunks residue smells. Opened the windows, ran the AC in circulation mode. Still persisted.

I inspected the lid. It had been closed/locked with the cap connector cord (thick black wire) lodged between the lid and car body. Tucked it in, and locked the lid. Petrol smell did not come back.

Thanks for sharing that. This again shows that vapors leaking from the fuel cap can and do indeed reach the inside of the cabin and can be the source of petrol smell in the cabin!

I am highlighting this because at first it sounds illogical that fuel cap leaks can be a source of petrol smell in the cabin. When I mentioned my case, even my friends asked me how come the smell comes inside the cabin if there is leakage of vapors from fuel cap. Sounds just implausible at first thought.

But as you and I found out in our respective cases, fuel vapors escaping from the fuel cap can indeed reach inside the cabin somehow and can give that petrol smell inside the cabin.

If anyone else gets a petrol smells inside a cabin, please be sure to check the fuel cap for any leaks before doing further investigations.

Amazing review. Reading this, I have decided to take the plunge for a ScorpioN Petrol AT. I was contemplating mileage (Diesel AT) vs ear-to-ear G-R-I-N-S (Petrol AT) for weeks on end. The Turbo Petrol from Mahindra is a fantastic engine. And then, there is something to be said about that high seating position!

Great choice!

- Would recommend waiting for the 4-door Thar whose launch is just around the corner. Will be a lot like the Scorpio-N in ways, will be a lot different too. Compare both and pick the one you love more.

- Don't know your running, but if it's high, still go for the diesel. The Petrol AT is a royal guzzler, suitable only for those with low to moderate running per month.

Rush, you can infact look towards remapping your Petrol Thar. The exact same hardware lies in the Scorpio N too, so reliability is not a concern at all. FE too remains more or less the same in the 200bhp tune.

Thanks for the suggestion! Any reliable sources for this remap? Are there no changes in the hardware / turbocharger at all? Do you know of Thars that have done it?

I might consider it down the road, but not top priority because of my extended warranty (already 6-7 niggles solved) and the fact that the Thar already has more power than it can handle.

But the 0 - 100 will be more fun with 200 BHP . That's like 30% more power.

Absolutely no change in hardware (Injectors, turbo fuel pump etc..)

Yes, a I've heard of a couple of vehicles done that. However, I might not be able to point you to a right source. Sorry for that.

As a pet project I had a manual do that and boyy.. the way 4th gear would pull across its rev range would put all those premium cars to shame. You should however, hold the steering dearly and handle her carefully!

Two days back, at the fuelling station, the attendant opened the cap, and it just fell to the ground. I wiped down the cap with a cloth, and put it back after the fuel-up. On reaching home: The attachment cord has come out from the holder. Also when the cap is opened/closed the cord twists and winds around the cap. That caused the cord to come off the holding pin. Should not the cord free-wheel on the cap, when it is twisted clockwise/anti, irrespective. Should I ask for a replacement. Will warranty cover it. 3 month old jeep.

Also something else I noticed only in the Thar during fuelling. After 2-3 liters, the dispenser auto cuts. Then the attendant starts the flow again. When I opened the cap at home (as mentioned above), immediately there was a loud "woooosh" popping sound from the gasoline tank of the Thar. Is this normal. This gas release causes the fuel dispenser to cut off.

Need some expert guidance on a particular modification on the Thar.

My dad drives a 2022 black Thar. He tends to bump his front bumper a fair bit (maybe because it stretches almost half a foot past the bonnet) causing it to break. It has been replaced once but it again has a big chunk missing, with the cross-sectional plastic frame visible now on the left corner. After seeing various examples on TeamBHP and out on the road of Thars with metal bumpers installed, I too am considering getting that for my father as in case he hits a wall or a tree guard, at least it won't snap break like the stock plastic one and the black color would go with the car anyway. What I'm confused about is how an after-market metal bumper plays into safety with regard to the airbag opening, impact absorption, crumple zone technicalities, and pedestrian safety in case of an unfortunate accident. Other concerns are about warranty (till Nov 2024) and insurance (modifications to the body). I apologize in advance if there is an obvious explanation that I am missing or if this has been discussed already and I've missed it. In terms of external mods, I have just gotten the Wrangler-style grill fitted to the Thar until now but that is a plastic/fiber piece so I assumed that wouldn't cause issues. Thanks in advance for all the help that follows.
