Mahindra team came to the house to test the battery. The 3 cells which had shown as red / discharged in the hydrometer on last visit magically came as white / charged today. The team changed the hydrometer so not sure if last reading is correct or today's reading is correct.

Also, my car has a 70AH battery. What is the right battery size for the petrol AX7L ? I read in a few posts that the car is supposed to have a 90AH battery.

So, 10 days have passed and my battery tester today showed last 10% battery available. We will now check the battery on the coming weekend to see battery status. My gut feeling says another 12-14 days and the doors won't open.

Hey Folks, has anyone done an upgrade to the AX7L audio system like door damping, door speaker upgrade ? want to know what's the feedback and improvement seen. I am thinking of damping but happy with speakers as such but wouldnt mind if sound gets better

Hi everyone,

I bought the XUV700 Diesel AT recently and have clocked 1,000 km in two weeks—mostly city driving. Fuel efficiency so far is 12.7 km/l, but I’ve been noticing a few things and wanted to get some insights from fellow owners.

DPF concerns – Given my driving is mostly in the city (highway run on weekends), what’s the best way to avoid DPF clogging and related issues? Any smart ways to manage this?

AT holding 2nd gear – I’ve noticed that the transmission holds onto 2nd gear longer than expected. Is this intentional to keep RPMs high and prevent DPF clogging, or is it just how the gearbox is tuned?

Mileage – In bumper-to-bumper traffic, fuel efficiency drops drastically, which makes me wonder: Can it be inferred that as long as mileage stays above 12.5 km/l, the engine is running at a pace that helps burn off DPF buildup more efficiently?

Average Speed – My MID shows an average speed of 29 km/h. Is that a factor to keep in mind—like a threshold below which DEF consumption or DPF clogging might become a concern?

(And yeah, I know diesel + city driving isn’t the ideal combo, and DPF concerns come with the territory. Just trying to be smart about managing it better!)

Would love to hear from those who’ve figured out the best way to manage this, especially in city driving. Any tips or habits that have worked for you?

Appreciate the advice!

Bangalore is much worse than NCR in terms of avg speeds. I do get 10-12kmph during rush hour commute and I am in similar situation as you with D AT. Some things that I am doing are, once a month weekend run as much as possible. Also in some stretches of commute i switch to manual mode and keep 2nd gear driving at about 2500 rpm. The soot should burn beyond 2K RPM when engine is hot. Gearbox does hold 2nd gear bit more in AT by default. Could be regen but i was similar thing on XUV500 also.

Fuel efficiency is about 10kmpl for me in BLR city. It drops more in bumper to bumper traffic cause car is always in coast mode and being constantly braked. You can try switching to N when idling in traffic. This will help a bit.

I have requested a dozen times over last 2 years to get someone senior from mahindra to come and check the car but no go.

As others have said, this probably is a vehicle specific issue and not a generic one.

I have just one suggestion for you - if you want to have peace of mind then stop purchasing the battery from ASC. Go to a good and reliable battery shop and get a new battery of required AH. M&M is known to save cost by providing lower spec batteries in new cars. In the initial batch of diesel XUV 700, M&M had provided a 72 AH battery where the actual requirement is for a 90AH one. In 2024 cars M&M provided a 80 AH battery (by OEM catalogue) stamping it as 90 AH.

Personally I feel dealing with M&M ASC is too much compared to the amount you would spend on a new battery from the outside.

You're thinking too much about the DPF issue - just enjoy your car as it is meant to be. Once in a week take some time out and take the car for a 50 KM ride on the highway and you should be good.

M&M cars are normally tuned for performance rather than mileage. the 2nd gear holding for longer than expected is for this reason.

One way to avoid the DPF issue is to shift to manual mode and drive one gear lower than normal. This helps the engine to heat up more and thus burn off some of the soot.

@sommos - I have got the battery replaced free of cost under warranty. And with the way battery keeps dying in my car I will buy it from the dealership simply to get easier replacement because the dealership can't blame the car if the battery dies while if the battery is bought from outside then the battery shop will just argue the battery is fine and the car is faulty. I am stuck with a lemon

Thanks. Will try these two out:
1 manual mode
2 shift to N when idling

But I was wondering—is there any specific metric that can act as an early indicator of potential DEF issues? Something like fuel efficiency or average speed that can give a clue if the driving pattern is putting the DPF at risk?

There is no other way to figure this. There might be some OBD parameters but will require bit more technical expertise to figure that out. I would suggest that dont bother much about it. Just enjoy the car and drive the way you want.

I am going for XUV700 AC7 Diesel AT PDI that got allocated to me.

Is there any specific things to check for Diesel AT based on recent experiences of members who bought in past 3-4 months?

[DJjoshi]

Hi,
I bought my AX7 Diesel AT last year in July 2024, the PDI expert (CarVaidya) identified that the tyre manufacturing dates were a year old than the car manufacturing date. He also mentioned that he had observed this issue in many XUV7OO at that point in time. You may want to particularly check this.

Book a PDI with Zekardo. You will get a comprehensive report. I had a good experience with them, I was buying a 2024 model which had been lying in the yard for a month so was a little apprehensive. But seeing the Zekardo executive in action (he took close to an hour) and the final report put worries at rest.

The tyre manufacturing week and months are not the same. The month and dates for all 4 tyres are - 4024, 4124 and 2 tyres with 4224. I was unable to see details of spare as I could not go under the car.
The dealers are not allowing third party PDI unfortunately.

Unfortunately Zekardo is not available here. I had sent them a feedback link on opening in my city, but have not heard back.


The issues I found are listed below:
1. Car was not cleaned at all, so it was impossible to find any issues in paint quality.

2. Some bent elements on the radiator behind front grille. Can these be from any stone hitting the car when it was brought from stockyard to showroom?


3. Foot marks in door speakers as if someone's shoes rubbed against these



4. DEF level was not 100%

5. Some kind of marks seen on tyres


6. Tread marks on the tyres were not looking too good although the tyre date is from October 2024 (Tyre showing 4124)


7. Boot door panel lights not aligned with the ones on the side


8. Larger gap between the boot glass and the boot door panel. Can rain water seep inside the boot door due to this? Can existing owners share if they have such wider gap below boot door glass and tail lamp?





Saw couple of other XUV700's parked in my apartment and found the panel gap is not this much in them. Below is picture of the same panel gap from one in my apartment.



The bent element on radiator, tyres not looking new and the larger gap in boot door are the items I am worried about and I am not sure if these can be fixed. The door scuff marks could be cleaned.

I noticed the same exact problem on my vehicle I was doing PDI on and a few others that were parked nearby. I mean, I don’t understand why’s it they haven’t got this right even after 3 years. Uneven panel gaps everywhere.

Not a single new tyre spike/hair? and if there are more scuff marks on the radiator then these two would be the red flags to further check for me. I was told the vehicles come from factory with a one time odo reset possible at dealer end, you could check with them if they are willing to reset it for you and if he refuses then that would be another indication that the vehicle must have run more and the odo reset done once already.

Boot door alignment is a straight forward adjustment using turning adjustment bushes on the inside, you can get it done during first service.

The screenshots you shared have almost similar gap as the one that is allocated to me.

Is the first screenshot from your car and did you finally the car with the larger gap?
Did the showroom provide any solution for fixing the gap?
Have you noticed any issues due to rainwater in this gap?
