The Mégane II Owners' Club

Hi Guys

Please be patient with me, I am a mature lady with a car problem I just can't seem to get accurate advice about.

I have a 2004 Renault Megane hard top cabriolet. When I try and open the roof the boot starts to open on one side only (offside) the other side of the boot trys to open so the hydraulic ram is working but the release catch in the boot does not release. The message "Roof Mechanism Fault" displays. I have had a few other problems with the car being damp due to water ingress. I have had to replace the front driver side Temic unit due to this. I have reluctantly taken the car to the local Renault dealer who did not even look At it properly (still charged me £60 for the privilege) and said the release motor was broken and I needed a new one at a cost of £752! Whilst I am prepared to accept this diagnosis I am not 100% convinced that this is the actual fault. I have trawled through a lot of posts on the forum and have read that it could be a fault with the sensors.

I was going to try a roof reset using the excellent instructions on these forums but they seem to be for a soft top. Will the same reset work with a hard top?

Any help you can give me would be very much appreciated. I have waited 40 years to be in a position to buy a convertible and cross this off my bucket list. It is sad that I can't enjoy it!

I wait in anticipation.

When it sticks try closing and reopen again. Mine had simlar issue when 1st bought on the 2nd open attempt it would work.
I kept spraying the catch mechanism with silicone lube after a couple of weeks of this lube onslaught it works ok now.
If this is not an option for you it could be catch not releasing at all in which case try ebay search breaking megane cc and ask the question how much for this catch another option is www.partsgateway.co.uk take a photo of catch go to site input reg number of car ask for the catch and attach photo this site then sends the request to renault breakers around uk and they send quotes to the site its quite good I just bought a good leather driver seat off it for £60 including post.
In short u either have a dry catch or its getting no power I think they are electrically operated.
Hope this helps a little.

Yes, that's what I do too when mine sticks occasionally. I don't completely close the roof again, just press the switch in the close position for maybe a second, and then open it again. Touch wood, ... that has always worked for me.

Hi all

This forum is awesome. I contacted https://www.partsgateway.co.uk website as suggested above and within minutes was contacted by a parts company who could supply me with a replacement boot catch for £35.00 with a 90 days warranty. It arrived yesterday, was fitted today (a fifteen minute job) and all is now OK.

I saved just over £700 by coming here for advice. Thank you very much.
