306 Cabriolet

Collection of articles including fixit guides

Since 2003, a series of articles were freely published on the Peugeot Cabriolet Owners Club website providing technical guidance and other useful information.

These articles are then illegally reproduced and sold on eBay as a PDF guide. So, to help owners of 306 Cabriolets all over the world live with their chosen ride, this PDF is now published for free here - exactly how the original authors/contributors intended!

Thanks to all those who produced the original material for these articles (see www.pcoclub.org/articles for full details and additcional articles).

Roof not retracting fully into boot space

Problem description

The roof is about roughly 6 inches short of being totally retracted in to the boot space, hydraulics can still be heard working, but the roof isn't going any further. Then all of a sudden, the boot lid starts closing before the roof has fully retracted! At this stage, the boot lid closes onto the protruding part of the roof and everything goes dead as the roof ECU realizes there's a problem and cuts power. A manual reset is then required to regain electric roof power.

Is your problem exactly the same?

To find out whether you are experiencing the exact same problem, you need to check whether the roof can be manually pushed into the boot space or not. If the roof will fit into the boot space by manually pushing it down, then you'll have to look elsewhere on this guides for a possible fix as your problem will probably be of a hydraulic nature. However, if it won't push down into the boot space, electrically or manually, then read on...

What is wrong?

The most likely problem is that it is no longer folding correctly. The reason is because the 306 Cabriolet roof is partly held together by a series of elasticized straps and allen-keyed joints. As the roof retracts, these elasticated straps pull certain roof bars into their correct position in order for the roof to fold up properly. Over time, these elasticized straps become stretched and naturally loose their elasticity, and eventually, are no longer capable of retracting the roof bars correctly. The joints are also quite prone to seizing up over time.

Which roof bar?

The one that generally causes the problem is the second bar back from the front of the roof (see picture below for location). If this bar does not retract backwards correctly, the roof will not fold correctly and will cause the problem as described in this article.

Location of roof bar
Tools required:

Start lowering your roof as normal, but stop at the point when the front part of your roof starts to retract backwards (as pictured above). You will then see from the pictures below (inside car shot and outside car shot) the problematic bar and elasticated straps referred to. You will also see the allen key fittings to this bar from the inside of your car picture.

Allen-key joint


Elasticized strap looped around end of bar

You need to tighten the elastic straps as circled. You can achieve this by either trying to tie a knot in it (to shorten its length) or by looping the elastic around the end of the bar, which makes them much tighter. Your best option is to loop them as per the picture above, try using a long screwdriver to do this. Be careful as the bars have sharp ends.

Next, slightly loosen the allen key screws and squirt some oil on the joints (see allen key joint below). Naturally, you need to do the same on both sides of the roof.

Slightly loosening the allen-key joint to assist lubrication

Basically, what you are doing is tightening the elastic strap, enabling the bar to be retracted in to its correct position during roof operation, and lubricating the two allen key joints to allow its free movement as they do tend to seize over time and use. The picture below shows the bar and its correct direction of movement when folding - and you can see the elastic strap is taught.

Direction bar should move when roof is folding

Fingers crossed, when you next operate the roof, it should now fit the boot compartment properly as the problem bar now retracts correctly.

Additional notes

If your elastic straps are well and truly stretched, you can, of-course, replace them by purchasing similar elastic from a local haberdashery shop and attaching the new elastic in place of the old, although this is a fiddly job. Also, by simply loosening and oiling the allen key joints, you can vastly improve the bars movement, allowing for you to manually give that bar a backwards push from the drivers seat during operation, ensuring it folds backwards correctly.

Time required.

Literally a 5 minute job!
