W169 panoramic sunroof help

[mioba]

..pretty crappy these A class panorama roofs. I would assume these plastic clips like all plastic weathers Being subject to hot and cold then gets brittle and snaps.

if you have the part the MB part number is usually stamped on it

Nice while they work, but built to a price. I've seen my fair share of questionable "engineering" on cars over the years but this one raised the eyebrow a few more millimetres. The failure mode seems to be poor quality moulding/design, topped off with a sprinkle of 'make it a difficult as possible to fix'. Sadly the part numbers are not visible whilst installed and I'm not sure if the parts can be replaced in situ. Everything I'm finding seems to suggest removal of the entire roof to repair. But hopefully someone on here can help me out with some info, part numbers or maybe a walkthrough.

Thanks in advance.

Fixerupagain,
Have you read back through the posts? If you do there are ones giving wonderful advice on how to negotiate the fixing of the problem. Not easy for non technical people but it's there.

Hi. Yes, I have read through the entire thread and wonderful WIS captures posted by GLK - thank you. It's looking more likely it isn't an in-place fix. I believe the part number for the repair kit is A1697800244? If anyone can confirm. Has anyone here carried out this repair? Any tips welcome.

Cheers.

Hi, the problem I have with mine is that the 'plastic' panels have become discoloured and rough, though just in patches. I have tried 1000g wet and dry then Tcut to no avail, just leaving a matt patch.
Im thinking of trying the blowlamp next as this is how they 'flame polish' cut acrylic

Some ueseful Info I have tripped over in my travels.

The sunroofs are manufactured by Webasto.
Here someone completely refurbed his W168 which I assume is similar.

How much of this can be done with the roof in situ depends on what has broken.

FWIW Buyer beware on these replica parts. I purchased several sets from various eBay vendors including the one quoted above. ALL of them were sub par in quality, being either oversized, undersized or in a couple of cases, warped - making them very tight in the roof frame. None of them had the internal cast metal reinforcement either. Your millage may vary, but the amount of effort that goes into this fix makes the kit from Mercedes a no brainer. I spent near enough the same amount as the kit trying to find decent aftermarket parts to no avail.

Prep and lacquer them with a good quality 2pac clear coat. It's the original UV coating that's failed - had a very lengthy telephone conversation with a Webasto engineer about it when trying to source replacement seals for the slats- which aren't available even though they are easily replaceable. You need to remove the outer layer of oxidised material before clear coating, but they'll look brand new afterwards and hold up much better than what was originally on there. Failing that, there's a German guy on eBay that is selling reconditioned slats already clear coated for those who want a simpler solution, not cheap though.

Hi, I am afraid I have yet another question about panoramic roof repairs.

The links and info in these posts have been very helpful. Sunroof is currently removed and I am trying to re-build with the MB repair kit.

The kit includes 4 of these parts



These parts are also included in the Ebay replacement parts.

When roof was dismantled only one was complete and I didn't notice exactly how its was fitted, it sort of fell out.

I have searched this thread including the otherwise excellent Youtube videos but they never come in to view.

Would anyone be able to explain where thes 4 parts fit, rebuild stalled at present.



Thanks in advance.

Does this work better, follow the series by CATAHA though the language is only in German.

Hi,

Yes I have been using this video and the other ones on CATAHA series, they were very helpful for the removal of the sunroof from the car and stripping the roof down.

I have also got the MB official guides such as the AR77.20-P-1710AK which covers installation of lamella guides.

These little "t"-pieces show on both the official MB parts list for W169 panoramic roof and in the Ebay replacement parts.

However the do not appear in either of the relevant CATAHA videos, the other 2 attachments show the parts which are re-fitted.

I am thinking about doing a trial re-build as per CATAHA videos and test it before re-fitting to car.
