removable sun roof.

[tony1066]

i'm on my second porsche . the first was a 924s i now have a 944s2. i have' on occasion removed the sun roof from both cars, hoping to get some sun on my bald patch!, but encontered serious buffetting at anything above 35-40 hph. i've tried changing the angle of the wind deflector but to no avail. am i missing something? i wonder since the cars are supplied with protective bags if it is assumed that owners won't want to go quickly with their roof romoved

Nope, they're just rubbish IMO. I'd far rather not have one.

The only way I have found to totally remove the buffeting is to open the windows just a crack too, and then adjust the angle of the deflector. The only thing you get then is the increased road noise. Well worth it though, it's a smashing Targa Top []

 

[Guest]

As far as I've heard it is possible to fit stiffer springs in order to prevent the deflector from folding back at all, as the originals wear out pretty quickly (to put it in a more PC way than Fen [])

I never had a major issue with buffeting, although being shorter I would be sitting further forward than most, and lower down!
We did have to cover anything on the back seat with coats etc if traveling on the Autobahn - or things would get sucked out of the opening in the roof!

I don't understand the comment on the bag? It is to protect the roof, and has ties to hold it firmly in place during enthusiastic cornering etc. Why would the presence of a protective bag, mean that owners would not want to go quickly with their roof romoved?

Just recently bought sunroof bag, but haven't experienced the joy ( or buffeting ) of removal of sunroof. Went through the motions of releasing it but chickened out at removing it completely in case I couldn't get it back in. It was 9pm and didn't want a sleepless night!

Hope I'm not teaching Granny to suck eggs, but it's worth repeating as some have damaged their mechanism by not reading the manual []

To unlock the sunroof, switch the ignition key to position 1 only - dont start the car

Press the sunroof UP button. With the key at 1 it will actually make the posts go DOWN into the roof.

Then unclip the front two clips and put sunroof in boot.

After experiencing the wind in hair and buffeting experience put the sunrof back, do up the clips and start the car. The posts should now rise out of the roof by themselves. If not press the UP button again.

I found it buffets so badly at motorway speeds that it gives me a headache. You can actually feel your ear drums moving. Horrible!

It doesn't feel like the roof is out either because you don't see any sky in the top of your vision - the hole is too far enough back.

You are right Paul in so far as this is how they are supposed to work. Mine has a problem with the microswitches which consequently allows the legs to retract completely when the roof is down and in pos 2 (i.e. the engine is running). This is a bit of a pain as, if I play with the sun roof, I have to look up at the legs to make sure they are at the top of their incline when I want the roof panel locked in [>:]. A little job I must get round to.

I agree with Fen, I'd be much happier without the lift up roof. What with dodgey locking, and leaks, they are just a pain in the bum. Peter likes the roof out but from the font seat, appart from the noise, you are not realy aware that the roof it isn't there.

You might have something there Thom. My deflector stays pretty much vertical, and I don't get any buffeting. I haven't tried it at any 'serious' speeds though... []

 

[944Turbo]

yes, in my experience you have to move it to eliminate buffeting and at higher speeds vertical is the way to go, I believe the VW phaeton has a motor to adjust its flap and avoids buffeting automatically - Fen you are spoilt by the Cab!

...and which is may daily bus again, you'll all be pleased to know. The GTI is on the market, to be sacrificed to great God of Tubots. (No money saved since I started "saving" for the rebuild and not going to have it ready for Le Mans otherwise...[8D]

Excellent be nice to be see it up and about again,

I can't think of a better cause. I wonder if the great compressor diety would accept seven year olds?

Back to the thread. I hate sun roofs. I have considered tank taping mine shut for the winter just to confirm if the water is coming in through the seal or somewhere else. Assuming you have aircon, I can't see the point of the sun roof apart from to take off to let out all the water laiden air caused by the frog swamp in the back.

Any chance of a bit of advice. I removed my sunroof today for the first time since I bought the car in November to see what might be causing a slight leak on the drivers side. When I put it back in the drivers side lug was higher than the passenger side meaning that the sunroof was not down correctly on the drivers side. I played with them up and down for a while then removed the sunroof again and found that one side would no longer go up and down. I pulled out both lugs hoping I would be able to line them both up or adjust and now I find that when I put them back in neither go up or down. Even with both removed the cogs don't seem to go around although I can hear the motor. Could it just be that the cable has come off at the motor end? I will take a closer look tomorrow. Any thoughts would be appreciated. Nathan.

Ah - it looks like you have discovered the very common problem of the sunroof cogs stripping [] Luckily new cogs are less than a tenner from an OPC (or other suppliers) and there is a comprehensive guide to home repair at http://www.clarks-garage.com/ in the garage shop manual and also at http://www.type-911.co.uk/images/general/text/944%20Sunroof%20Operation.htm

 

[cuffn]

Thanks very much, I'll take a look and see what I can do with it. Regards. Nathan.

Well I ordered the gears and only got around to opening up one of the assemblies today at lunchtime (having read all the info from the web sites - thanks!) and found that the gear was fine. What happened when I pressed the switch was the drive cable (coil of wire thing) disappeared down the sheath never to be seen again. I didn't have time to look any further so had to put it back together as is and when I came to go home the motor seems to be operating continuously and only stops momentarily when I pull up to a stop. It starts again as soon as I pull off and trying the switch does nothing. I was a bit worried that the motor might overheat and catch fire on the way home! Anyway the car is ging in to Northway Porsche tomorrow for a 12K service and a few other bits so they are going to have a look for me. Anybody had a similar experience before?

 

[cuffn]

Well it's now sorted ! Aparently there were a few expletives coming form the technician at Northway today as the drive cable/coil thing had gone right back down the guide tube and out the back and tangled around itself by the motor! It's now been reset up with the cam and microswitches and the new cogs fitted for good measure and works a treat.
