Hey Folks, one question around REGEN. On fri evening when I got the car back from valet at a hotel, it had the regen message showing up which eventually went away in 3-4 mins of idling. Post that it did not re-appear however I did ensure I drove a bit on highway on the weekend to unclog the DPF. My car is at 1300 km with weekday driving in BLR traffic and some lit bit longer runs on the weekend around BLR.

Does regen msg show up for a brief moment like it happened for me? or stays permanently till resolved?

Same thing happened to me as well. My XUV 700 was in service center for repair work and because of prolonged idling, I started receiving DPF clogged notifications. It kept popping up on console until I drove it for 10-15 minute above 60 KMPH and then it went away on its own.
I believe if you don't clear the DPF clogging by driving on the highway, it will eventually force you to do parking regen.

I visited service center yesterday for my 1000KM service. The issue was temporarily fixed when they re-flashed the firmware. But popped up again while I was about to drive home. As per SA, this needs to be debugged further by their technical team. I am going to visit the SS again in few days.
Any guesses what could be wrong here ? Will there be any part replacement required here ?

Service update :
The issue of drive modes was root caused to silver box not functioning as expected. Service center has placed an order for a new silver box. Hope this resolves the issue once and for all. Am I being the unfortunate guy here ? Or is it Mahindra part quality/ quality control to blame?
I had one more issue wherein DEF percentage level shown in display was not changing. I was worried since DEF sensor is prone to failures (unlikely on brand new cars though). This issue was also root caused and fixed. It was an improper fitment/ loose connection apparently.

When the soot level crosses a threshold value (weight) then the REGEN telltale sign comes up. At the first level you can perform a manual REGEN either by driving the car on the highway at 60KMPH or more for 20-30 minutes or through the instrument cluster.

When the soot level crosses 20 grams the REGEN telltale sign appears continuosly. At that time a forced regen is to be done by the ASC or if you have a OBD diagnostic tool you can initiate the regen through the connected mobile app.

Hello,
I own a petrol XUV 700 and a complete newbie in cars. Sorry for long the long post ahead.

Background of the issues:

Last year at around 9,000 kilometers, the vehicle displayed a “Check Engine System” warning, and the control valve oil pump was replaced at the service center to address that issue.

Recently, before i was about to go for 30000km service, i checked the engine oil level and found it to be low. The car is currently at service center for 10 days. No clear root cause for this issue was provided by the service center, they instead suggested replacing the following parts - spark plugs, oil pump, piston cooling jet.

So I escalated through customer care and right now I am in touch with Area customer care manager from Mahindra over email. He has emailed the same resolution as the service center head. I had asked him for these two assurance -

1. I need written assurance that the suggested repairs will resolve the issue permanently and that if the same issue or any engine issue occurs after the repair, I demand that Mahindra commits to replace the engine.

2. I also need written commitment stating that the vehicle is free of any accelerated wear or damage in engine and it's components because of this issue and that it'll meet Mahindra's specifications for performance, safety, and reliability post-repair.

For that i got this reply,



Is there anything else that can be done or should I trust them and go ahead with the suggested repairs?

[Rockstah]

Update - so I got this reply after I emailed them again



I guess they have no idea why it's happening, for now i have authorised the mentioned repairs.

Engine oil level going low is normal and did you do any top-up during this period. The most possible reasons maybe -

a. Leakage from the oil seals or bottom pan - this would be apparently visible if you check the underbody.

b. More serious problem would be any leakage due to bad or faulty piston rings. The oil somehow gets past the piston rings into the combustion chamber and gets burnt. There may be a loss of power but a much sure test is to check the compression ratio of each cylinder.

c. The last reason can be a faulty PCV valve or bad intake and exhaust valves in the cylinders. A taletell sign of this would be black smoke from the exhaust when you press the accelerator.

d. Another reason could be improper specification of engine oil - but I assume the engine oil has been changed by the ASC.

Spark plugs and oil pump do have a role in this but I am not sure about the third part. As you mentioned that issues with the oil pump was already detected earlier and replaced under warranty. If the car has been used for 20K KM with a faulty oil pump, there is a possibility that some damage to the engine may already have occurred. However, don't take me too seriously, I will leave this matter to the senior members for their opinion.

The Area Manager will only repeat the views of the ASC as he depends heavily on the diagnosis of the mechanics. Try to talk with the Regional Customer Office or the Plant Technicians and try if you can get satisfactory reply from them.

This has become an issue with petrol XUV, many people are facing this and some have got their engines replaced because of this.

I have approved the replacements so I don't think there's anything more to be done now.

Final Update - I have taken the car back and it feels way more responsive than before. I've been told to bring the car after 5000kms to recheck oil levels.

Does it mean you have replaced same oil pump twice?
Once at 9000 and now.

If so It's a matter of concern for other owners.

If team BHP through their research could find out whether many customers were required to replace oil pump,then it may become a case for recall.

At 9000kms only control valve for the oil pump had been replaced. Now OIL PUMP ASSEMBLY has been replaced, along with the other parts. If you have a petrol XUV do check engine oil level.

All these parts were changed in my XUV 700 at 26K Kms. it all started with a check engine light - they changed the oil pump, oil pump assembly, spark plug and some solenoid valve.

If anyone is looking to disable the Auto Stop-Start feature on the XUV700, I have managed to do it in a very low tech way. Thanks to everyone on the forum for their suggestions, especially @rroy92

Original idea came from the video posted in this thread: https://www.team-bhp.com/forum/diy-d...ml#post5899014 (DIY: Disabling Mahindra's Micro-Hybrid (idling start/stop system) for good!) see post #12

I've outlined my hack in the DIY thread: https://www.team-bhp.com/forum/diy-d...ml#post5898856 (DIY - Permanently disable Auto Stop-Start on the Mahindra XUV700)

Folks, have you experienced eSim suddenly becoming non-functional and requiring a reset? It has happened to me 2 times in the last 1 month and reset at service center is nothing but a battery disconnect and reconnect to reset the system. Both times it happened when I was in basements with no signal which is very common given that we park in basements all the time in cities. Not sure if its a common problem or specific issue with me car.

haha this is awesome hack thanks for sharing. I have gotten used to turning it off each time now.

Yes, it happened with me quite a few times as I also park my car in basement with no signal at all from the eSIM and I do the same battery negative terminal disconnect and reconnect by myself to restore the signal. It has become more frequent of late and not sure if any of the latest software updates have fixed this permanently.
