AUTO STOP/START LIGHT STILL FLASHING AFTER BATTERY REPLACEMENT

Hi there, I was hoping someone could help me.

A few weeks ago while driving, the Auto light (Start/Stop light) began to flash on the dashboard which had never occurred before. After I parked up for a while, the engine began to chug when I turned the ignition on but eventually started, with the light flashing once again & the stop/start not operating.

I then stupidly left the car parked for a week or so, and when I started the car it did not start. I knew straight away it would be a flat battery after reading online that the Auto light flashing is a sign of a weak battery.

I had managed to jump-start the car with leads, and this solved the problem. The car started fine with no Auto light flashing. Start/Stop tech even back working.
Everything was fine until 4 days ago when the Auto light began to flash. I decided to book it into a garage to have it investigated, as the engine chug had returned as well when turning the ignition.

The mechanic got back to me advising that the battery and the alternator were actually fine - holding a charge. But I decided to just go along with a battery replacement anyway - which he duly obliged.

I picked the keys up earlier today and left the car at the garage as I had to return to work. When I got back to the car later on, the Auto light was still flashing and the Start/Stop tech still not operating!

I’m really at the end of my tether with it - especially going ahead with the battery replacement which I believed would resolve the issue.

Any help or advice would be greatly appreciated.

Welcome to the forum. We have seen similar issues reported before here on the forum. If you use the search you might be able to find a couple of them. Correct me if I'm wrong, but I believe the Auto Start/Stop is a feature on the UK or European Jukes. The North American Jukes do not have this feature so there's limited knowledge about it. My initial thought would be the alternator was not charging properly. My second thought is something is draining the battery when parked. I've seen stuck relays cause a battery drain issue.

Hi thank you for your reply.

Yeah sorry, I should have made that clear - it is a UK model.

I actually had the old battery and the current alternator tested, and they were both holding a charge. But I decided just to go ahead with the battery change because I had been advised that the old battery was the issue and that there was evidence of the same thing happening on the 2013/14 models (which mine is).

I have Googled the hell out of it, and it all comes back to same thing - the battery being the issue. I thought a replacement would have solved this, but it hasn’t

In the past, alternators have been checked and reported as OK, only to find out that replacing the alternator fixes the problem.

I realize there is cost and risk involved, not knowing for sure if it will solve the problem. I always recommend that people have problems serviced at Nissan dealerships as they are more knowledgeable about our vehicles (which have gotten more complex in recent times). Often times, your local mechanic doesn't have the tools, knowledge, and or training to diagnose and service newer vehicles. So if you want to be sure, take it to a dealership.

just for the heck of it. Read the owners manual and see what it says about the systems(s) in question.

Had this issue after queuing for petrol and the stop/start and lights drained the battery right down. Tested battery and alternator all fine in my 67 plate 1.6 DIG
Seems to me that once the light starts flashing it's impossible to turn off even with a replacement battery or your battery being OK. I solved this issue by buying a OB2 scanner/ Creader on ebay for £15. No DTC error codes found on scan but reset the ECU and cleared the codes anyway and light now off and stop start working again. Cheaper than taking it to Nissan just to reset at £80 an hour for a diagnostic. Handy little tool to have (y)

I know this thread was a while ago but you are my absolute saviour!! I was going insane, new battery etc and the flipping light still flashing! Nissan wanted £168 to plug it in so bought the OBD2 reader £14.79 Amazon, ran diagnosis and no errors so hit reset and boom no flashing light!! Thank you so much!!!!!! Now I pray it stays off 🙏🏻🙏🏻
