My daughter recently tried to get the hood on her 51 Renault Megane reset.
She had turned off the ignition on the car while operating the hood and this had caused the hood system to get extremely confused. Following the directions in the drivers handbook we released the hydraulics (for hood cover) by using a small tap in the boot and then as directed pulled the release strap found in the small compartment in the luggage area.
What we didn***8217;t know is this is a no return situation and the mechanism (similar to a bonnet release catch) will disengage and there is no way of getting it easily back into place.
The Renault garage mechanic charged 1 hours labour to diagnose that the complete release mechanism needs replacing - £405 including VAT.
SO...This morning I removed the mechanism and quickly re-seated the release catch and then reassembled the mechanism. The hood now operates completely fine. There was absolutely no reason to change the mechanism.
The whole job took me just under an hour ***8211; bearing in mind I am a computer engineer and not a car mechanic and know nothing about Renaults at all..
To prevent this happening to others I have included a very quick guide of what to do if this happens again. I realise this will not fix all Renault hood problems but should at least be tried first and 1 hour labour should do it***8230;
1) Release hydraulics on hood cover by undoing the small tap located in the boot (under left hand carpet in boot)
2) Pull manual release for boot cover ***8211; located in the boot area <> rear seat compartment (Step 1 and Step 2 better documented in the owners manual)
3) With the Hood nearly closed (but with the back window in the air !) and the hood cover opened ***8211; by hand, remove the 2 nuts that hold the rear seat onto the rear bulkhead.
4) Now use a star / torque drive to remove the 4 screws that hold the hood release mechanism onto the rear bulkhead.
5) There is no need to disconnect any cables just remove from the cable clips.
6) The release mechanism can now be viewed easily. Look to re-engage the cam that the emergency release cable is attached to into the metal arm that is driven from the worm gear on the motor.
7) May need to engage small micro switches on the mechanism to get the worm gear to operate (do this very carefully and by holding the switches on while operating the hood from inside the cab. (need 2 people for this) Operate the hood only for short 1-second bursts until the worm gear allows the cam to drop easily back into place.
8) All above sounds complicated but actually when you have the mechanism laying in front of you in the hood storage space area its very straight forward and should take 30 ***8211; 40 minutes maximum for someone who has seen it once before.
thanks to others on this forum - I tried and succeeded in saving over £400 in repair bills. I have now asked the Renault gave to refund the £40 charged for wrong diagnosis - they obviously dont have access to this website
