- In this weeks video, we find ourselves in a sticky situation with the DREADED d.e.s.s battery failure.
After its pampering session down at ROYAL DETAILS i came back to the car completely dead.
It was only a matter of time and things COULD have been worse... BUT, we move forward, and in doing so i have a go at replacing the over complicated unit myself!

PART NUMBER FOR BATTERY IF NEEDED - 24410 1440R
I thought on the rensport uk forums they mentioned on first starting the new battery, you need to drive a few metres and all the settings would reconfigure.
Have also heard here in Aus that a larger 50aH battery can be swapped out for oem 19ah. Thanks fr the video, am currently a 300t owner…. So keen to see this
Cheers for the info mate! Clearly theres alot to look into with these batteries so I'll see what i can did out!
Another good video, keep them coming and glad you got it sorted!
Thanks mate!
Great video, we have to change our car batteries every 2-3 yrs here in the tropics, out q7 battery cost nearly $800!
Thanks dude! And i wouldn't mind changing a battery that often, but I don't want to be stranded at the roadside 😂
I'm sure I gave you the part number for this fix lol good vibes mate 👍
Maybe somewhere along the line you did mate! But it actually died on me last week and i managed to get one from Renault (much to my surprise)
I had an issue with mine but touch wood it’s ok now. Yellow spanner came on and the SOS light changed colour!!
Afortunadamente mi clio usa bateria normal cambio facil afortunado que sabes resolver tus contingencias👍
Yeah also had battery issues when I had mine... So can relate to this ... Daily'ing it did help.
Absolutely mate. I drove it every day with no problems, then the incident happened and it all went downhill...
Bought the Megane in 21 battery died today ,24. hopefully ill call them if they will replace under warranty. 3 Years Only and driven only 8000 kms.
Just re[place with an standard EF or AGM battery like fitted to the non Trophy RS Meganes. Can't remember why they fitted to DESS battery to the Trophy, but I'm sure there'll be some waffle in the original bumpf somewhere.
Basically the battery is a lightweight race battery. Its got 19ah of capacity which is tiny. Usually they are about 90ah. Rather than redesign the whole battery tray renault just fit the lightweight battery in that enclosure so it fits straight in.
The other half of the DESS case is full of ultra capacitors. It is designed to be light weight but this battery is unique to Renault and the Meg and not typical of modern ICE cars
Mine was fine, never had an issue however I knew that the Trophy had a lower capacity battery to that of a normal battery (19ah in the DESS vs 50ah in a normal car) so I just adjusted my behavior around it accordingly. Some people dont realise what they have and as such this is where problems start. Due to their lower capacity when they start to fail, they fail quick, generally after a heavy discharge. Of curse, there are some issues knocking around as well.
I also belive some people use the wrong size chargers on these. The handbook states no more than 4amp hr charger should be used otherwise the charge rate becomes too much and buckles the lead acid battery.
When mine failed, it was perfectly fine the day before, no issues starting but then the first cold snap and it refused to take any charge. Thankfully I always carry my jump pack permanently in the boot!
There is some suggestions that an EFB or AMG battery can also be fitted, but Renault UK do not recommend but give no explanation as to why other than the 'regenerative' braking setup.
Yeah its strange mate isn't it!? Mine had no issues at all but like i mentioned in the vid i think where mine was in the body shop for a month barely ran that was the start of the failures.
Wish I could work out how to remove the front half of the air intake, I broke mine trying to remove it.
Oh shit dude really!? Mine just pulled up from the intake side then slid out the front
What's the top speed, did you test it?
thanks bro
Always had a Noco jump starter hooked up to the USB in the glove box, my battery was shot after less than 1k miles, never trusted it fully after that. Do miss her like crazy though 😢
Yeah I've seen people running trickle chargers mate, i use mine every day so hadn't needed to but its just such a strange way of doing things! I've never owned a car that just depleted while sitting...
@@VersionOneUK it gave up the ghost being washed, I didn't turn off the auto lock and as I was moving round the car it was constantly locking and unlocking which drained the battery, I couldn't get it to start for love nor money! I'd only had it a week and she was only 6 months old, the dealer I bought it from (DT Performance) went to London from the Midlands to buy a battery and brought it to me and fitted it the same day, this was during lockdown and as I was a key worker, he wouldn't allow Renault to have the car taken to London to be fixed. I think the first owner bought it, drove it for a few hundred miles and left it in the garage doing nothing for 5 months, seems when they go dead they never recover! It went dead again randomly on the second battery but I'd already decided by then it was time to move on, I think I went through 3 pairs of front tires and 2 rear in 13k miles, so it was an expensive habit! 🤣 I'm the guy that bought your panel filter off of you, I think it's still in the shoebox you sent it in in my shed, I sold it about a week after you sent it. Nice to see you enjoying yours 👍
@@OnlySCHUMI Oh shit dude thats ROUGH!! Yeah luckily mines still going strong
@versionOneUK,
If I am able to 1 of the DESS batteries I want to follow your video as very well shown and explained. The only question I do have is when you changed the batteries was it just straight out and in with new 1, I mean no software or anything to get started?
I didn't do anything extra mate, although apparently there is an update you can do at Renault, unsure what it does exactly and its not cheap but apparently it sorts the battery issues from then on
Thanks Mate,
I was driving about 10miles from house not drive the car for 3 days, otherwise drove everyday no problems. Car just lost power and cut out, couldn't start again, Tow Truck home. Jumped it and ran while on jump leads but cut out again on own, but have read alternator don't charge when idle or accelerating. So putting all money on battery
Changed Battery today, car started but sounded like a small misfire, and then cut out and wouldn't start again.
Any advice mate or from anyone?
@@stephenmedland56 you did a like for like swap!? The start up you see in the video was my legitimate first start with the new battery, burst into life no problems
Yes got from renault by me £189 +VAT,
The car started and then cut out, it was the same with the AA they had jumps on and car started. Took jumps off and cut out and wouldn't start again.
Someone told me was alternator or fuel pump or injectors? Don't know where to turn.
Fantastic
Good video
Can I ask
Please how much was the battery
Tim
From Renault direct mate, think it was 160...
@@VersionOneUK Thankyou
That's better than I thought
I have a face lift 2022 car
I wonder if they had sorted the battery issue by then
By the way I love it
It's in a heated garage on a really good trickle charger not using it over the winter period
I have ocd
@@timnewbury1792 i feel the facelift cars have this problem sorted, I don't know for sure but theres a software update available at the dealer if not, apparently not cheap either...
@@VersionOneUK Thank you
Please please please do more content on your love rs
Now it's all sorted
Looking cool
I'm looking at wheels
Perhaps
Concaver cvr4 I think
What's your opinion in double black
@@timnewbury1792 black on black looks stealth! Check out my older videos of my clio RS mk4, that was black on black 🔥
I see you have the dreaded “Check antipollution system” error. I have the same too, but my Megane is bone stock. Any ideas on what might be causing this? Have you had it checked out?
Mines because of the GPF delete mate, but I've heard there is a sensor on the turbo that can get sooty and sometimes become an issue... If not, then you may have an issue with your GPF unit
Hi , I have a straight pipe on my Mégane rs 280 , when driving the car hard and when the car gets super hot I get the electric failure light , can you advise me what’s the possible problems
Unfortunately mate i have absolutely no idea what could be causing that! I've never had that issue but I'd go get it checked sooner rather than later as i assume its getting so hot it's burning something electrical
Could you leave the battery fitted in the car and just remove the lid to swap the battery over?
Can you tell me what is done to fix the fuel pump issue?
Cheers mate.
I reckon you could leave it in yeah mate, but it was FREEZING and i needed more light etc to film easily... As for the fuel pump, my recall came up 'fuel pump sensor' so my actual pump wasn't replaced as far as I'm aware
If you have the 5 year renault warrenty the fuel pump is covered
do you have a link for the battery? Part number 24410 1440R points to a regular sized battery but in your video it's the smaller battery from the DESS system
It shouldn't do mate... I ordered the battery from renault directly, i just called them and checked for availability and they had one on the shelf
My Trophy battrery gave up. Took it to Renault for repair. They say warrenty will cover 50% of the cost leaving me with £120 bill for replacement battery. Replacement battery didnt fix the issue according to renault and the issue was "more technical then anticipated" They have had the car two weeks now, only just fixed it so not sure what the problem is as i'm yet to pick it back up.
I was also told that it was a known fault on the MK4 and i should go to halfords and buy and keep a battery recharge pack. Renault wanted £230+ for one off them. Kind of embarrasing that a flagship performance car has an issue where the manufacturer has told me to go to halfords as a temporary solution to the problem happening again.
I had the car at 8000Miles. 19k the fuel pump went and i was left stranded on a cross roads no power nothing. Had to go back to Renault, was fixed under warrenty. 24k current mileage and battery has died. Probably started flagging low battery at approx 21k? I had noticed not long after purchase if the car radio was on (no engine) it would do a 15min cycle and flag battery low turn on engine. Not sure if this was normal behaviour?
Crikey it sounds like you've been through it mate!
The only electrical issues I've had was the battery issue was LOOMING so I didn't want to risk it and let it go completely so replaced it, and randomly twice its thrown and ABS fault after cleaning the car, a sensor gets wet and it doesn't like it, won't let me apply the handbrake or anything...
@@VersionOneUK I got a quote from renault to supply and fit two front brake pads, want to charge me £600! I'm picking the car back up tomorrow, going to argue the £120 (50% of the warrenty cost) Seems to me it should be covered
@@Asherlee101 I won't ever get work like that done by renault mate... robbery
@@VersionOneUK Odd update from Renault. They had to replace a 12v Capacitor in the battery to get it to start working again. apparently they had limited options as waiting for stock of batteries was crazy lead times. To make things worse have also found out that between the capacitors is some type of fuse component (im not technical on this so apologies) apparently if this blows renault have no stocks and cant get the parts any more because it is completely discontinued. At first they thought this had happened to mine and there at a loss as to how going forward they can replace/fix these with the parts not being available.
The trickle charge pack was recommened to me in the event i dont drive the car day in day out. To prevent charge being lost when not in use.
They also honoured full cost of the replacement when i argued about it being a known defect. Had to play my face a little but at least its been honoured as they dont cover batteries under any warrentys
Just had the battery low start engine come up on mine today, still starts at the moment fine but should I change it ?
Get it health checked mate, could be fine and the warning just being thrown. Take it for it a rip and see if it goes away
@@VersionOneUK thanks mate, will do 👍🏻
Any more issues with the battery? Looking at these but this issue is putting me off, can’t have the car let me down
Nothing ever since mate! Have my carly OBD reader now to check battery health etc, there is an update that can be done too to prevent this stuff happening directly from renault
@@VersionOneUK thanks mate
I have the same battery and it's dead, where did you bought this spare one? How much did it cost?
Currently I am using a normal rs battery because they asked me 800 euros for a new trophy battery
Its an original battery from Renault for the trophy mate.
HI,
Could I ask what battery you class as normal rs please.
I need to get my car moving and really just want a normal battery for short term
The battery looks like an odyssey pc680. Might be cheaper alternative to the renault part
Could well be mate! I was in a sticky situation so i needed a quick fix and was lucky enough to be able to grab one locally!
The main reason i done this vid is to show people how easy it is and shed some light on how this thing even works because I hadn't seen anything like it before with cars, and I've been messing about with them since i was a kid!
Can you replace battery with just a normal one or does it need this oem one
I believe there is a battery you can use instead but I'm not 100% sure. Renault now do an update for the trophy to prevent the battery issues from happening so I've heard
My turn to play battery bingo. Finally got locked out of the car having to open with the manual key, while alarm was sounding. Stupid design by Renault, they should have product recalled the battery, as every one fails. Normal AGM ordered.
Hi,
How did you get on with a normal battery?
Mine has gone and just want to get a normal battery , did it work? If so do you have the part number off the battery please. Thank You
I have been going through this bullshit for the last 3 weeks mine also blew a fuel pump at the same time so twice in the last month it has left me on the side of the road for 3hrs pain in the arse an not good enough renault recall it check your fuel pump as well ash mine kept blowing fuses
Already done fuel pump recall mate 🙏
I fear for us ash these meganes worry the fuck out of me mines done 15 thousand klms had rear shocks replaced gearbox replaced 2 battery's replaced fuel pump replaclaced let me down 3 times called for a tow truck the renault dealership in Australia reminds me of a shit episode of the 3 stooges fuck me
