Electronic Handbrake - DIY Repair possible?

Hi,

First post so hello

We purchased a 2004 Megane Scenic 1.6 VVT a month or 2 ago and it's been serving it's purpose of ferrying the family about quite well.

Yesterday, my partner pulled off the drive as normal (hand brake auto disengaged as normal) but before she had got to the end of the road, there was a warning on the dash saying that the parking brake was at fault. When she got to where she was going, the hand brake will now not engage. The handle appears to do nothing (bar flash at you). No sound from the motor etc.

So, I've trawled through a number of threads on here but in all honesty, nothing has really helped much, hence why I'm posting this here.

First off. If there is no sound from the motor, can I assume it's dead or that the parking break unit is dead or is there any possiblity that a fuse could have blown? The Scenic manual is possibly the most unhelpful lump of paper I have ever come across so I can't even single out where a fuse for the unit would be. I have checked the fuses under the bonnet and in the glovebox but none appear blown but then none appear to be related to the parking brake anyway...

If the motor is dead (how can I check?), is it possible to do a DIY replacement? Can I just buy a new / used unit on ebay (the prices are eye-wateringly high ) and fit it myself or does it need programing to the car or ned the use of a dealer only tool?

Is there a guide anywhere of how to fit a new unit? WHere abouts under the car is it located?

Any other help appreciated. I hate modern cars with a passion. All this electic crap really puts me off working on them. You would never guess I'm actually quite a competant spanner monkey.

Re: Electronic Handbrake - DIY Repair possible?

The handbrake module is under the car. Look at the rear calipers and follow the brake cables back to the module. The are programmed to the car, unfortunately. I want to get hold of a dead one to see if a repair is possible. Normally it's either a sticking pad/caliper or damage to the brake cable that causes them to fail. If I had a dead one I could investigate further. I beleive there is a relay and a motor/actuator inside the module. Relays are relatively easy to fix, I've repaired hundreds of the old Jaguar light modules. If it's the cables sticking or the caliper, these need sorting out too. There was another thread here somewhere about a polish guy that fixes them for around 70. I'd have a search for that first.

Re: Electronic Handbrake - DIY Repair possible?

Thanks for that.

Pretty much rules out me doing it myself then

Guess I could take it off, strip it down and try to determin what caused the problem but then I still have the issue of a dead unit that needs replacing anyway.

Probably one to give to a garage and pay up then.. Wouldn't be so bad if it wasn't such a total and utter waste of money. Could stick in a new engine for cheaper than getting the handbrake fixed...
