I'm getting desperate with my MY2006 Grand Scenic, it has no handbrake (broken) and MOT is getting closer. A new electric unit would be 1300 eur from the dealers so that is out of the question. Have been looking for a second hand unit but in Finland seems difficult to find. As I'm no ttoo familiar with breakers and their habits I'm asking if anyone knows anyone who might have this part in their breakers... or could give a hint who to mail/calll for such part.

Have you tried dismantling/cleaning/reassembling the unit :-\
iirc, Jasonm had some success fixing one a while back... might be worth sending him a pm to find out if what he did can help you :y

Hi KCL,
Can you tell me what the EXACT problem is with it? I may be able to help you. What happens when you pull the lever on the dash? Can you hear the electronic motor whirring at all???

No, it does not whirr when trying to operate the handle. It was stuck on once, then released from the emergency handle. Opened the unit, cables run ok, lubricated them. Found that the blue relay on circuit board was overheated, replaced the relay and it still wont work. When trying the "reset" (door open, long press from the start button etc, this should run the motor so that the cables connect again) the motor does whirr but nothing really happens. The handle has been opened and it works ok. Read the codes with CLIP and it says that the emergency handle has been pulled and says also that the 12V feed on start-up has not been detected (but the feed is there, it would not whirr without 12V feed when pressing the start etc...)

Sounds more like an electrical problem than a mechanical one. Could be one of a number of things -
There is a clutch position sensor on the clutch pedal that could be faulty / wires broke / rusty or contaminated this speaks to the ECU and can cause problems if it is in some way broken / not working as the unit will not respond in the correct way and get confused.
Also there's a manual release switch (inside the mechanism) also that throws up errors if it gets accidentally upset whilst stripping the unit down.
When you replaced the relay did you check all the other circuits to see if they are continuous and don't have broken or burned bits?
As for getting a second-hand unit I've heard that you cannot interchange them as they are programmed to be used once only , However I know someone who picked up one that matched his car spec. exactly i.e. same model & gearbox and it worked :-\ :-\ :-\

Sorry, do you mean brake pedal? My Passat will not release the parking brake, unless the brake pedal is pressed, doesnt care about the clutch :-\ :-\

Nope, definately on the clutch :)
On them daft Renaults you can say put the parking brake on if you're stopping on an upward slope, and then engage 1st gear and as soon as you lift the clutch & get biting point the handbrake will release automatically.

Not daft, it's hill start assist. :P

I know, ok till it goes wrong and you can't move the B****y thing and are stuck at a junction with an ever growing annoyed queue behind ya ;D ;D ;D
But that's Renault electrics for ya :D ;D :D ;D
:P :P :P

Some of the captiva ones are starting to give trouble on the Chevvy forum. Fickin stupid, unnecessary gizmo. Give me a proper handbrake any day. In fact...I would deliberately ask the salesman if any vehicle I was considering buying had one, then tell him I didn't want to buy it.
-
I never know how they (electric hand-brakes) got passed, I thought the whole idea of a a 'hand brake' is that it is an emergency brake as well as brake for holding the car still on slopes & when you leave it? I couldn't imagine what would happen if you pushed the switch in an emergency if ya foot brake fails :o :o :o :o
-
Hmmmm......an electronic handbrake turn...the would fick Tiff and Jason and Jeremy and Richard up.... :D

Yes, it is electrical, nothing mechanical. And its automatic so no luck with clutch switch. Have now found a second hand unit for some 300 euros, let's see if it works... A real pain the whole thingy, useless piece of xsxhit, why on earth have they ever fitted such apparatus to any car? And AFAIK all the Scenics are really suffering from this issue, especially here up north where winter freezes all handbrakes, mechanical and electrical. I really do wonder why it is essential to have this electric handbrake working in MOT as it is useless, especially in an autobox car...

Typical management thinking...
If the car breaks in a really irritating, yet expensive way, the customer will simply trade it in for another one...
What they systematically fail to grasp is that customers will buy another car, from another manufacturer ::)

Hill Start Assist and the EPB are two seperate systems.

Exactly. But still, this Grand Scenic is by far the most comfortable car I have ever driven and I have driven many. Quiet, spacious, bright with glass roof, does have most of the "needed" equipment (raintronic, reversing sensors etc), goes straight with almost no need of any steering. Though on negative side the interior is very cheap-looking, seat cushions are very short with no support to thighs, front of the car is out of the sight making parking difficult until you learn where it goes, third row seats are practically useless unless you have passengers without legs... Value for money is excellent IMHO. Still the overall comfortability is better in Omega, Omega is more "sturdy".

Double check all the multi plug at the motor and on both the hubs for broken wires inside the connectors. Ive fixed a few in the last 3 months and it was broken wires on the rear hubs where the sensor wire is attached

There are no wires from handbrake module to the hubs? Or are there? Which wires do you mean? ABS sensor wires? ABS works fine, so does ESP/ASR.

No electrical wiring on the rear hubs, the only mulit-plug is the one to the main unit, and when you open the black box the wires leading to the motor & circuit board.

Yup, I agree, that's why my questions to "hoofing it".

Ok, now I have handbrake on the scenic again, bought a used unit which still was expensive but nevertheless needed this part to clear MOT. It works ok from the handle but the warning on dash is still on... sigh... I do have CLIP to use on my laptop but I'm not too familiar with this program so if anyone has any ideas or expertice on this please tell me where and what to click in CLIP to have this new unit configured correct and to get rid of this fault message.
