Mahindra Scorpio-N: Repeated Check Engine warning irritates me

When checked in manual, it was clearly written that it will blink or be on continuously in case of an actual problem and the same was told as a sensor miscommunication by the Mahindra technician

BHPian nandakumar recently shared this with other enthusiasts.

Wishing you all a very happy Diwali and hope it was safe and joyful.

I got my new Scorpio N Z4 AT post the second service (10K) from Sireesh auto in Bangalore. And about 1K kms later while we were in hills, it suddenly started showing the "Engine" error with a warning but was not continuous or blinking but will come on for 5 seconds and will go off only to come again maybe an hour or 2 later.

When checked in manual, it was clearly written that it will blink or be on continuously in case of an actual problem and the same was told as a sensor miscommunication by the Mahindra technician from Sireesh Jakkur.

On my return to Bangalore, I went to the service center to reset the alarm but the scanner didn't throw any warning nor the warning history and they sent the car back saying all is well. But again yesterday I got the same warning and this time I took a video and sent it to them.

They have instructed me to leave the Vehicle in the service and they will get back once they figure out what the error is. Now what should I do?. Is it common to get such errors in ScorpioN or something serious. I hate leaving the beast in the service center for unknown period as they are not committing a timeline to sort it out.

Need some advice here and please find attached the picture of the error

Here's what BHPian dhanushs had to say on the matter:

With so much electronics now controlling literally everypart of new generation cars, I think it will be a good idea for all car owners to have cheap handheld OBD Diagnostics in hand. Sometimes these errors, if it doesnt reoccur for a certain time, will get cleared from memory.

If you have a handheld cheap OBD Diagnostics tool, you can plug it in the time of the error and log the error.

This will also help the service centers to work on effective solutions based on the error codes. Without any codes, its like firing a bullet in the air.

Here's what BHPian Jeroen had to say on the matter:

Yes and no. The biggest problem with cheap OBD scanners is that they are known to damage the car electronics. From the frying pan into the fire as they say.

The other thing with cheap scanners is they might not be able to scan manufacturer and or model specific codes, only generic. You also need to check which subsystems are scanned.

You might also consider getting a scanner that can reset codes. So when you have a problem, read the codes and reset them and be on your way. A real problem will pop up again, but a random, intermediate issue might not.

I carry a pretty elaborate scanner in my Jaguar. Because it is known to throw the odd, completely random code and put the engine in safe mode. When that happens I coast to the side of the road, read the codes and reset the, so I can be on my way.

Note: a scanner that resets codes, resets all codes, also the codes it can’t read! So if your scanner can’t read a manufacturer specific code, it will still reset it.

Good luck, careful with that scanning, make sure you know what you are doing.
