I know this thread has been previously made, but it is over 2 years old and i hope to bring my set of problems to the table. I own a '07 Daihatsu Copen. It is my very first car. but now, I seem to have some troubles getting my roof and boot to open up. Here's what i suspect happened and the problems i face: I had my boot protective sheet engaged to the sensors and then filled the portion closer to the entrance with stuff (the section between the sensor to the trunk lip). It wasnt anything too significant, because the boot closed just fine with a slightly raised drop and no force on my part downwards. I proceeded to lower my roof. After a short drive, i raised my roof and then realised that the roof light would not go out. As soon as i had the opportunity, i opened up the boot and removed my stuff. Now, im stuck with a perpetually on roof light, with no ability to lower the roof. I also then suffered many difficulties with the boot opening button. The boot refused to obey me. Basically it went to the point of me needing to press the button about 3 times before it can open. After a long long time (2+ months) of diagnosing the problem, it is now clear that something with the motor in the boot is wrong. The two locks on the side refuse to engage when the boot is closed. The motor is warm as tho it has been running. So im not sure if its cables, wiring or the actual motor itself that has blown. Right now, ive removed the motor, set the locks manually and tied some cables to the blue emergency release locks. So the boot can close completely avoiding the chance of rain seepage. I would like to know your thoughts and opinions as to how i should approach this. In Singapore, copens are immensely sparce and all specialised workshops have vanished. All copens are bought in 06 to 08 and parts are hard to come by. I was intending to make a few phone calls for a replacement motor, but im not sure if i can run a diagnostics first. Should i plug the motor in before i attempt a diagnosis or leave it out? Should i keep the boot open as i run the test? Or close it? Any help is much appreciated!
A lot of the original people who used to post on here seem to have gone. Its unfortunate as plenty of people like myself still own these cars with low mileage. There are a lot of posts regarding the roof problems on this site and how to reset it when it won't work. If your roof light is on then it is caused by the door switch? Open each of your doors and push the switch in or wriggle it etc to test it? You may have to put a washer or something like that to engage the switch so the light can go out. This has been a common problem for quite a few people on this site. I would doubt there is anything wrong with the motor unless its smells burnt? I bought my Copen with a roof & boot problem. I fixed it myself by resetting the computers. The boot one worked fine but the roof still wouldn't work. I actually found a broken wire on the plug in the boot where it is. Once I fixed that & reset the fault it worked fine.
hello everybody,my name is mr ian im from Jakarta, Indonesia. my car problem is the roof can't open because the roof pump is broken. in Daihatsu Jakarta and other garage diagnose that the problem because of the broken roofpump.so i need get the new one. anybody know where i can buy the new roof pump in Asia ? my copen is 2003. thanks before
Hi everyone! I'm a Copen newbie from Singapore, and I've been having problems with getting the roof to close... It opens fine but struggles to close, and often just flops back down. A bit of manual help pushing it up to the point where gravity takes over usually does the trick. The garage has said it's a roof motor issue, and I've found a reconditioned part here: Daihatsu Daihatsu Copen Roof Motor and Pump Unit All Models 2002-2010 Roof Motors and Pumps Would like to ask the many experts here: 1. Has anyone ordered parts from them before, are they okay? and 2. Has anyone tried installing this part? Tha garage claims it's complicated and he has to bleed the air from all the 8 tubes etc and needs a day to work on it. Many thanks, Robin : )
Hi robin. I actually managed to get my fix at a shop in yishun/nee soon which specialises in copen works. They managed to identify my problem and very promptly replaced the motherboards, fixing the roof and boot problem i was facing!
Thanks very much, Debrisbits! : ) Can you share the name of the workshop you went to, please? And how much it cost? Thanks again for that super fast reply. Happy to meet up if you have time... robin
Hi Mr Ian, I've just ordered the roof motor part, and the site owner assures me it's an easy DIY installation... will let you know how it goes when it comes... if you're looking for the Roof motor and pump solenoid, a reconditioned one on the site costs 50 pounds before shipping costs.
Hi, Robmob! I also have a roof opening & closing problem, and I was wondering how was your experience with the Roofmotor was. Thanks for sharing your experience.
Having the same problem here. Roof opens OK but for the last few months it struggles to close so I have to try to reach over the wind deflector whilst activating the switch and revving the engine. I can just about get my fingertips under the roof to help it up until it's halfway closed then it's OK. I presumed it was the battery but I had it tested and was told it's OK. The car does start every time although I rarely use it and the cig lighter batter gizmo from Ebay says it's OK. So what can be wrong with the Webasto roof motor which is causing this problem? I live in Thailand and no Diahatsu dealers here (import tax/duty is over 20k GBP alone on a new Copen).
Maybe grease all the joints and slide rails on the roof with white lithium grease, it might just be insufficiently lubricated, which makes it harder for the motor to close the roof. Just a thought. Have you taken a look at the pump under the carpet, see if it is leaking fluid or looking damaged?
No Salieri, not looked, I will look tomorrow as it's late here now and try to buy some white lithium grease which I've never heard of so I will google it!
Its something like this, many companies produce it. Its one of the most basic spray-on lubricants: WD-40 Specialist Sadly I do not know what its called in Thai
My boot is completely dry, no leakage of anything. I did notice there are two 'controllers' in the boot. The Webasto one, which has a plastic fluid reservoir , mine is up to the level with the cross, and under a cover is one saying Daihatsu roof controller, but this just seems to be electrical components. Does the fluid need topping up on the Webasto and if so , how?
I thought I would add some photos, hopefully you can see the fluid level is about halfway full, is this normal?
Try doing a search for the roof ECU. I think someone posted a link on the forum to a YouTube video that showed how to read the codes off the ODB port with an explanation of what the codes mean. Your boot looks in good condition unlike several I saw when buying my Copen. Usually the motor housing is anodised.
Hasn't anyone who has had roof opening/closing problems topped up their hydraulic fluid? I've done a search on the internet but can only find Mustangs which have a rubber plug on the end of the reservoir for topping up.
hi everyone! I am a copen user from indonesia, having the same problem here. my roof still work properly but it getting slower lately. I try to change my battery but nothing change. now if I want to close/open the roof I need revving the engine to make it close / open. looking for the answer as well, about how to change the hydraulic fluid? thanks
