Has anyone faced this issue in their TUV?

I have never faced this issue in my 4.5 years of TUV ownership, neither have I heard any other owner reporting this. Probably this is the first time I am hearing about such a kind of issue. Has your friend shown his car to the workshop?

Yes, he did take it. But with the issue not getting reproduced always, they as expected was searching in dark. He got his starter motor replaced, but that dint solve the issue.

I was about to point to the starter motor earlier but then thought if that was the root cause then the problem would have been even during the first start of the day, which is not in this case. Another issue could be the fuel pump acting up during the subsequent starts.

I remember long back, during my first service (3000 kms), the FDM (Fuel Delivery Module) of my car was replaced under voluntary recall. I didn't have any issues that time with the fuel supply or starting, however as a precautionary measure it was replaced under warranty. You can refer further details on my ownership thread. Please refer message#146

Did they run diagnostics? No error codes popping up? My guess would be
1. O2 sensor problem because of which supply is getting cut off
2. Issue with fuel plumbing because of which this issue happens sporadically

Did he get the fuel filter or any other parts serviced/replaced in the last few months?

My tank is not cranking today. Getting the attached error light. Any idea what should I do now? I drove it just yesterday for daily errands and it seemed fine. Not sure what the issue is. Battery is fine, All electronics are working fine.

Mine is AMT, and when I try to shift to A/M or R, it doesn't change and remains in N mode.

This was not done on his car. Will ask him to cross on this part.

They had mentioned that in diagnostics nothing turned up. He was not there at service center when this happened, so not sure if they did it really or not. He wanted to take it to service center to get it checked again, but thats when lock-down happened.

Yes, even I was wondering if it was something related to fuel line. But if that is the case, shouldn't it happen while driving too and not just when starting?

Else, no replacements done.

Appears to be the battery, is there a way you can swap the battery and check?

Not sure if it is the battery, I mean all the electronics in the car are working fine including AC and HU. I emailed customer service, they said they are trying to arrange for a technician but not 100% sure due to lockdown.

Does the battery also have impact on the AMT box? I am not able to change from N to A/M?

I am sure you would have checked the TUV manual. However, if not, this is what the manual says:

AMT warning lamp - Continuously ON Indicates malfunction of the AMT system. Contact Authorized Mahindra Dealer immediately

My understanding of the problem is that after driving for a certain period, when the car is switched off, he is unable to start the car again? Correct?

If this is the case, then it could be a problem with glow plug. Since its a coil, it would work well when cold but once it gets heated, it will start to show its age and could start to fail. The glow plug indicator lamp might not highlighted in the Instrument cluster, but it could be on its last legs.

It could very well be the battery as the amps needed to crank is a lot more than whats needed to keep the AC and other electronics working. If your battery is close to 3yrs old, I would suggest you get it changed.

Yes checked it. It is continuously on, previously it used to be on when there was some sort of wheel roll. However, this time there was no wheel roll. Any idea why a stagnant vehicle has AMT issue?

Battery is 3 years old, not changed since I purchased the vehicle. Will battery have impact on AMT gear box as well? My vehicle is not shifting from N to A/M mode or R mode.

This is the case in my Ertiga also that there is no indicator for a failed Glow plug. However, during last service they found out that all 4 plugs had lived it's life (192k kms) and had gone bad. The ASC didn't have stock of 4 plugs handy and I hence haven't replaced it at all.

What is important to note is that I faced zero issues with starting the car including my December drive to Gujarat where temperature at certain locations where I stayed was single digit.

Technically, it is very rare for Indian weather conditions where a failed glow plug will trouble a car to start. Moreover, the Glow plugs are supposed to aid the starting process during a crank when the weather is extremely cold.

So the question is : Can anyone who owns a TUV confirm if a failed glow plug has caused such issues where it doesn't start?

Yes, I will ask him to check the glow-plug. In his case, my friend is from Wayanad in Kerala (comparatively colder area). However, in such a cold climate won't it cause issue during cold start too?

In any case, will ask him to get that verified. His vehicle hasn't done much on ODO, just around 25K in past 4 years or so.

Maybe its not shifting because your AMT warning light is on. Would suggest you take it to MASS, check with another battery before replacing OR use a meter to check voltage readings before you decide to change battery.

I remember one example on the TUV WAG where someone had a glow plug issue. Not sure if it resulted in starting issues only when hot. Need to confirm.

Apparently even a weak battery can cause this - https://www.team-bhp.com/forum/techn...ml#post4677942 (Starting problem when engine is HOT!)

In my opinion, it should not cause starting issues.

I have also known a lot of Palios and Puntos in my circle that faced Glow Plug failures but never had any problems with starting. Like I said, failed glow plugs very rarely result in car not starting especially for general Indian weather conditions including winter except may be Himalayan regions.

But yes, do check within your circles. Never know if TUV is a special case although It should not be.
