More roof confusion.....!

[mattau]

Afternoon all,
Well i managed to get the 206CC 1.6 through it's MOT, after giving it full service, new discs and pads all round, new back box, and centre brake light. Bodywork now done, so with a dry day thought i would take another look at the roof..... It doesn't seem to have magically fixed itself unfortunately!

The problems as i see them...
Front clips undo fine, with the correct beep.
Pulling the roof button, the motor whirs, but doesn't seem able to free the bootlid lock. Possibly not enough tension in the cables?
If i move the u-clip into the manual position, and then pull the roof button, the bootlid lifts ok, and the roof starts to move backwards. It seems a bit stiff (car had previously been SORNed for 2 years) but moves, then stops, but with another pull of the roof button, it continues backwards.
At some point the motor seems to stop, and the roof falls slowly into the boot.
The bootlid stays in the raised position however, and the parcel shelf doesn't move.
For some reason, i think one of the problems might be the parcel shelf ram. If this doesn't raise the shelf, then i presume the microswitches stop the rest of the action.
Does anyone know if it's possible to just change the shelf ram? Does that mean draining the hydraulic fluid and refilling?
To get the bootlid down, i have to undo the hydraulic pressure and lower the bootlid.
The catches won't latch properly however in the auto mode.
As a result the roof will not raise hydraulicaly, so the pressure needs to be undone and the roof lifted manually.
Once the roof is in position, and hydraulics done back up and u-clips reset, the roof latches properly and i get the complete beep.

Closer inspection also suggests that the whole roof mechanism, or possibly some parts might have been replaced from breakers by previous owner. Some suspicious part numbers painted on some visible parts, which i presume Peugeot don't apply at the factory!

This in itself doesn't worry me, although i wonder whether things might be a little out of line, in which case i need to work out if any of the mounting points can be loosened up and adjusted.

I had hoped a combination of manual up/down movements might re-synch everything but it doesn't appear to be making any real progress.

Does anyone know a good tool that is capable of reading the roof fault codes (if there are any) as i would prefer to stay away from Peugeot if at all possible! Alternatively, anyone in the Kent/SE area have one and prepared to read my codes in exchange for beer or any other preferred poison?!

I know this problem is fixable, so will keep plugging away and will update if i discover anything, but if anyone has any suggestions they would be gratefully received!

Tks in advance
Matt

Sorry if post was too long.....

Does anyone know if it's possible to reset the roof computer/read codes apart from through Peugeot?

Has anyone changed the hydraulic ram for the rear shelf?

Is it possible to read the microswitches with a multimeter? (don't want to damage the computers etc)

Tks
Matt

Speak to Enright as he changed mine Monday, unfortunately didn't solve my problem but another thing ruled out!

You need someone with PP2000 to read roof codes.

EDIT: It's unlikely to be a fault with the ram.

[Enright]

Mattau, where are you based? (If you put your location in your profile you might find a helpful Peugeot Planet 2000 owner nearby)

[mattau]

Tks capncol and enright. Im in SE london/kent area.
Guess maybe the ram isn't getting the message then?
Is pp2000 obtainable? Or anyone within a sensible distance have it....?
Im happy to travel!
Cheers

Is this the right equipment? For loading on pc?
Cheers

[Enright]

Yes, the Lexia 3 is the correct interface. The PP2000 software can be downloaded for free via www.peugeotforums.com and there are people on there who can help you with activation codes etc.
BUT it has to run on Windows XP. No other operating system works. Not bad if you have an old laptop which can't hack anything newer, but to get round it with my Vista machine I had to fit a bigger hard drive and then install a "virtual machine".

[mattau]

Thanks Enright, thats useful to know. I do have an old XP machine kicking about somewhere, but would need the cables etc as well. If i can find them cheap enough then this sounds like the best way to look further into the problems initially.

You only have to do 2 diagnostic runs for the interface/lead to pay for itself, and if you do end up having to trust a job to a main dealer, at least you can present them with a screenshot and so save some time and trouble (especially with their hourly rates)!

[mattau]

Fair point. I will hav a look for the cable(s). Is it just USB to OBDII?
Tks

[Enright]

No - it HAS to be the Lexia 3. Although it does convert USB to OBDII, there's some kind of interface between, and I wouldn't trust anything else to do the job.
They are down to as little as £50 +P&P now, so well worth getting.

[mattau]

Tks for the info. I'll see where I can get one from quickest as I'm hoping I can get it sorted this week!
Cheers

Just an update. In the end i got an auto electrician out. Wanted a view on the problem quickly to have time to order parts etc.
I had suspected a microswitch, but we went through manual up/down of the roof and all the microswitches were responding as expected.
The roof seem to hesitate when the rear window is approaching the upright position, so looked for resistance etc. Couldn't feel any moving the roof manually.
Fluid is good.
Suspicion is that maybe the motor is on the way out.
The ECU seems to shut the roof down as the process is taking too long. We did notice a slight motor smell when looking in the boot. There appear to be signs of wear on the motor too.
Need to find a motor now to test.
Have replied to Enrights thread regarding the breaking CC he has.
Will post back when i get the new motor in to see whether that helps.
I've had the roof faults all cleared, so hopefully once the new motor is in it will be good to go!
Cheers
