Hello have Secnic II 1.9 DCI with similar problem
Display say low batt , Parking brake problem etc. and no star the fan starts when pushing start bottom.
Have been tru all fuses I can find seem to be fine.
Tester has been connected to car and can not find ECU (engine control unit EDC16 I belive) ABS , Servo Steering. All units found in engine bay seems somthing common.
I checked the Engine ECU and did not see any supply voltage on on any wires at all with ignition on car so this is clearly problem or part of it.
Tracked wire to fuse/relay box besides battery seems this does not switch 12v supply to the units. Got other one from junkyard but still the same, now I have been opening wiring harness and started to inspect harness seems ok from first view but really many wires.
Anyone know where to start or perhaps I am off the right track ?

All commments is apriciated very much

Thanks in advance
 
Well starting problem with Scenic 1.6 auto 52 plate, take it into Garage -and it starts without any signs of fault or problems, they stick it on the Computer, and it comes back as clear everything working ok. I decided to replace the TDC or Crank sensor that they called it £76 later the car is still starting ok, and its now a case of waiting to see if replacing The Sensor, has resolved the starting problem, or its another thing removed from the list of things that are causing the starting problems?

Basically the starting problems is still a Mystery and with the replacement of coils spark plugs, and even getting a heavy duty battery, didn't sort out the problem.

Water ingress (leak) from the roof, and wet drivers foot well, still hasn't really been resolved, but thats come up, as a possible cause, to the staring problems.
 
I had the TDC sensor (Crank Sensor replaced) This aided Starting, but even after a long run the car would once every so often (Out the Blue) suddenly have a dead battery ? I had the alternator checked and it was charging fine? So I replaced the Battery, as the Garage mechanic said that he suspected the battery was actually not holding the power. Since then I have (while it seemed to be running ok) Sold the car on. I will look at the more modern Scenic when I do buy another car, but I also have my eye on another popular sold car from another french car manufacturer, as my dad has one and in the 6 years his had his from New only the heater fan resistor has needed fixing.
 
I've got the same problem, I charged the battery which was low anyway. The dash lights come on everything works except the starter. Renault suggests a new battery, I had this battery fitted 2 months ago for the same problem and the alternator tests 100%.

I have owned many many cars in my lifetime, This Renault Scenic 1.9 DCI is the worst of all. It has had more trouble in 19000 KM than all my cars combined. Including 3 former Renaults, a 5TS, a 14 a 9 and an 11. This heap is a disgrace, I was going to buy a Nissan, but not since it has joined Renault. I prefer cars that I can drive around not store in the renault dealers fitter center.
Where do I find the ECU?? I expect to fully disassemble this money eating pathetic electronic liability.

Hi Guys
I've got the same problem with our 59 plate Scenic conquest 1.5dci.
Cars been stood a week in airport parking and now won't start coming up 'Battery charging fault' and the cooling fan spins up very loud when it should be starting and runs on after car locked
Tried various things to get it going, jump leads, charging packs etc.. just causing different fault to appear (low oil pressure, low battery etc..)
Battery tested and 11.99V so took that out to charge up.
Have stripped the fuse box down to see if any obvious water ingress or corrosion, none seen yet so going to put back together.
Would you recomend going straight to renault dealer for this fault (probably renault Manchester) or worth getting a local garage to look at? (local garage round the corner so can push car there or will have to probably pay to get it towed to dealers as already been towed home)
Thanks for any advise
Jim
 
Sounds typical Mk2 Dead battery. If it's been flat for a bit, then probably needs replacing. After all, it's 6 years old. If it won't jump, then It's REALLY flat.
Put a new, fully charged battery on. Should sort it.
Before fitting, check the fuses on the +Ve terminal for continuity. Should be 3.
Then if still no joy, that's the time to find an expert.
Local Indy, before Dealer IMHO, unless you like an empty wallet. :smile2:

Thanks. I've just tried taking the battery out of our other car which is slightly lower capacity and 2 years older but seems fine on the other car, still same issues although I managed to close the windows which helps a bit. Put the original battery back in and the dash display won't even come on now. The original battery definitely is dying and I've failed to borrow a charger. I'm fairly tempted to take the plunge and just buy a new battery but I suspect it won't cure the problem :(
Struggling to find a local Indy in Stockport/Manchester as that would definitely be my preferance!
 
Have you checked the three fuses on the battery plus terminal?
Under the red cover there are these fuses.
Look like connectors but are fuses.
And can break with no visible sign so need a test light or multimeter to check.
With no dash I would suspect one of the smaller ones.
 
I've disconnected the negative terminal of the battery to avoid draining the new battery until I've figured out what to do with the car. Are there any downsides to doing this except being able to lock it?
You CAN lock It.
Bonnet Up, Passenger door open. Flick the interior lock button. Disconnect -VE. Shut bonnet, Shut passenger door & lock with emergency key from the keycard.
Check Emergency key works BEFORE you do this, Please.
Or leave it open & hope it get's nicked, problem gone.
Not Recommended, just humour. >:)>:)

Update: Car is now fixed and running.
The fault was a corroded wire on the wiring loom that runs to the left hand side of the battery.
The cause seemed to be a badly routed earth wire that was running over the top of the loom and rubbing against the wiring loom causing the sheathing to be damaged and water to get in.
It was obvious where the wire was damaged/corroded as the wire was green in colour and broke very easily when pulled. A new piece of wire soldered in and running again.
I used a mobile specialist (not sure if I'm allowed to mention them) who spotted the problem and fixed it very quickly.
Very happy to have the car working again
 
I don't think the forum (a mod will no doubt jump in if I am wrong) worries too much about positive reviews or naming people who have given good service.
There is a reviews section in the Forums that is specifically for that. Just make sure it is your experience and not a trade advert.

Forum has to take a differing view on naming and shaming as this could fall into libel laws and not only the author (the poster) but the publisher (the forum) could find themselves being bombarded with lawsuits. Which can be expensive even if without merit.

Nice one on the fix and thanks for letting us know.
Sounds like an earth fault.
Glad it's sorted

Of interest, what was cost ?
 
if anyone else is having the same problem.. I just fixed mine, and thought I would share my experience..
dont know if this is related.. but the car was running fine.. and one day the steering lock would not come off.. I kept trying to start the car.. and on about the 5th or 6th time.. the lock came off
drove the car home and it was parked up for about 2 weeks
when I came to start it.. it wouldnt turn over, and came up with low battery, low oil pressure and parking brake failure, and the radiator fan was running..
checked fuses all ok.. was a new battery and still under waranty so I took it back and changed it.. still the same
read on here about the corroded wiring and fuse box problems.. so checked the fuse box and relays.. all good
was about to give up.. when I noticed a very small amount of green oxide around the wiring loom in front of the battery.. it was almost like a green ring around the wires..
I took the battery out so that I could get at it.. un wrapped part of the loom.. and there was 2 wires that had a very small spot of corrosion on them and they broke as soon as I touched them.. one was an orange wire and one was a white wire.. I stripped both of these wires and rejoined them with a new piece of wire..
these wires go to the brown plug with the black clip on the top of the fuse box..
anyway the car started first time with no messages on the dash.. so all fixed
the corroded wires were not in a position where they were rubbing on anything.. so if you have this problem look for the green corrosion
