Before some else mentions it how old is the battery? Have you tried to put battery on charge overnight. So many of these strange happenings seem to be caused by low voltage.

 

my old man suggested this I don’t have a battery charger to try tonight but can definitely get my hands on one tomorrow

I really do hope so cars been a dream since I had it mid last year can only imagine car has been sat at private dealership for a while and may well have a low battery will definitely check tomorrow and update

thank you

 

Yeah, I'd be starting with the battery. If it's > 4 years old, get a new one.

 

Really appreciate the help on way to purchase battery charger to try that if that fails will grab a new battery trying to be money wary as 3 kids and mortgage to deal with lol thank you

 

Quick update battery is currently on charge overnight will update tomorrow no issues today to and from work !

 

Another update battery full charged and “repaired” by smart charger , installed back in car , driving like a dream will let you know if issue comes back hopefully not !

 

Update , issue returned , purchased a new battery car fine for 3 days then same fault again lost for options at this point

I’m sitting in a parking lot right now with the same problem 😭 wondering if it’s an alternator issue?

 

But how old is your 🔋 ❓

 

Did you get the Battery Management System reset when you replaced the battery?
I'd do that, then get the charging system checked. As it's 'smart' it'll need someone who knows what they're doing.

 

After doing research was under the impression there wasn’t a need for a battery reset , how are these done any clue’s ? I’m currently waiting for RAC and a tow truck to get plugged into a pro diagnostic’s machine as fault seems to have stuck this time and won’t clear after leaving vehicle for a few hours - recent changes to driving style before fault re occurred - slight slip into reverse with Flashing R when selecting reverse then judder into gear and continues as normal ? Is this a switch failing maybe ?

 

I have scoured the interweb high and low literally not a thread I haven’t looked at , and can’t find a single person with the same issue that has solved or any idea what it is , starting to wish I never purchased this vehicle

 

annoyingly to reset the BMS you need a proper LR computer. I trawled round local garages, had some try with their generic devices and nobody could do it (though I imagine one exists somewhere). I ended up at a local LR specialist who sorted it out for me for around £60. In my case, the only problem was the stop-start not working but in extreme cases I guess it could cause charging issues. Still, the AA should be able to test the alternator whilst they're there.
Your theory WRT the switch is also possible however. Just odd if it works fine with a 100% charged battery.

 

Car is now on the back of a truck on the way to. LR specialist will update once diagnostics done. Hopefully it comes off the back of the trailer on the way there !

 

Halfords reset the BMS when they change the battery

 

Has anyone else with issue been getting a start engine, low battery message before there was a problem?

 

I didn’t , however low voltage will also cause this problem so charge your battery or get a new one , I fitted the battery myself I’m pretty sure on discovery sport there isn’t a battery management system you need to reset after changing it , I could be wrong but I didn’t do a reset and car was perfectly fine until intermittent problem occurred again. Waiting for Friday and full diagnostics then will be straight on here to update.

 

New battery Installed today. Still exactly the same scenario 😭 still says battery low start engine as well

 

Hope you the proper battery. What is the specs of the new battery Place battery on charge overnight and it should be OK. Some Discos need the BMS reset for the new battery and others get away with not doing it.

I have an update and unfortunately it’s not good , car has now been diagnosed at 2 garages both coming back with a transmission fault not TCM module , current repair quote stands at £7,000 as for now I’m taking a few days to asses the situation and figure out a game plan

 

Have you taken it to a ZF transmission specialist? they would know the most about the transmission assuming its the ZF 9HP48 gearbox.

 

Yeah it’s been too 2 specialists maybe not so much zf specialist but the one guy is very well spoken off around here , I’ve decided to have it taken to Land Rover themself who after booking it in have notified me that is actually wanted back in for a recal on the “ the epas motor bolt replacement “ but as I’ve had the car almost a year now and haven’t been notified about this whilst driving with 3 kids etc in the car I think I might be entitled to a small good gesture will apology so I’m going to play my hand tomorrow with customer relations I’m paying £225 for 1 hours diagnostic work with further charges for extra time and will certainly update with either a eye watering bill which I’ve just prepared myself to take straight on the chin in hopes that as this has now had new turbo , new bottom end or something along them lines , new dpf system new crank shaft and numerous other bits and bobs :/ that the car might last the 3 years I have left with it and get me a small return on my investment when sold

 

Btw as I have learnt a tonne about my car in the past 3 weeks lmao can now confirm it is a 2015 L550 discovery sport luxury 1999cc Deisel Automatic vehicle , really like the car just wish I didn’t have to deal with these issue’s

 

Have the garages checked the oil level in the transmission? the DTC P0936-64 Hydraulic Pressure Sensor Circuit Intermittent - Signal plausibility failure meaning Automatic transmission internal failure with the action being check fluid level, rectify leaks and top up, if that doesn't work install new transmission.

 

I can ask the question and relay the answer I’m assuming this would be included in checks , they said they had also tested all “accessible” wiring. I’m feeling pretty confident with the customer relations route it’s my expertise and I’m pretty sure I’ll get a discount out of them for my troubles
