wonky roof

[acer]

What do you make of this?



When the roof is up it seems to be straight. When the roof is down it seems to be fine also. However, we have noticed that the driver's side of the roof lowers at a faster rate than the passenger side. It means that mid-cycle the driver's side is lower as you can see above. Has anyone else noticed this on their van?

Our van does this, it is only ever a slight difference. With the roof fully up or fully down the roof is driven to hard end stops and hence normally flat.

When lowering the single roof pump is operating the two ram circuits at the same time and the two sides generally follow each other but not perfectly synchronised and the roof isn't rigid enough make them act as one. I am sure this is down to pipe lengths, part / ram variation or much more complex aspects of hydraulic flow/pressure rates that i don't understand.

That‘s interesting. I was hoping someone would say that. My old 5.1 used to be straight every time.

Hi, just raise it fully and lower....it will straighten out.

Ive had 3 vans & all 3 roofs did that when lowering.

I did try that, but no.

That‘s reassuring.

We've a 15 plate Cali and noticed this quite early on; from everything I researched at the time, seems to be a normal occurrence so now live with it!

Apologies - just posted in another older thread as I didn’t see this one …

This happened bringing my roof this evening. I’ve had the van six weeks or so.

I stopped at this point, but the difference really worried me. Should I be concerned?

I’d be taking it back to the dealers and showing the photo. This level of difference could cause creasing of the roof imo.

Take it back and get it checked, it might have also buckled/twisted the roof.

Thanks @Hawthorn37 and @Ch1pbutty …

Email with photo sent to Breeze Poole, who have since called and said the tolerance is approx 18cm, so it’s going in for two days for investigation, and the roof should not be raised before that.

Better safe than sorry.

There's a lot of different threads on this. Am trying to pull together warranty experiences on it on a single thread here.

I've also documented the TPI which a dealer has to follow. Interesting to say the least...
