Ok. Is it easy to check or shall I just replace and have done with it?

CTS?

I've checked all the connections to the coils and replaced the HT leads and no joy. However, what I have noticed is that the fuel economy is terrible. I'm getting less than 200 miles from a tank. I hadn't noticed it previously as it's not my only vehicle and I never set the trip meter but, I became a bit suspicious last week and decided to fill her up and do the trip meter. Is this likely to be linked? I've done a bit of reading online and I've read all sorts of possible faults from bad connections in the rear light units to blocked pipes but, I can't find a thread where someone has finished the topic by saying it's working, and this is what I did!

Cheers for the offer. Due to take the little one to Alton Towers in April but, if it’s not sorted by then, I will have set fire to it!

Cheers. I’ll have another crack next week.

The motor is held on by two bolts. I can hear the retainers rattling around in the roof somewhere. Ive quickly dropped the roof back in and fixed it in place while I sort out what to do with it. I’m off next week for a few days so I’ll have another crack at disassembly.

Is this the bit you’re referring to? It looks like I may be able to lift this tab up and release? Also, any idea how I’m going to refit the motor if the retaining nuts/fittings are no longer there?

I’m aware WD40 isn’t grease. Its had WD40 sprayed into it as a lubricant for about 5 days now. Its seized solid so I can’t get into it to change the mechanism. If someone can tell me how to get into a seized roof so I can replace the knackered drive, that would be useful!

Not yet. My thought was if the fault registers as a potentiometer fault, it’s possibly going to be electrical?

To add to the Lupos current woes, I’ve had the engine management light on since I got it. I thought it was the EGR valve but took that off, deep cleaned it, refitted and got a friend to clear. It came back almost straight away. Potentiometer for EGR, implausible signal. Any ideas?

The problem I have is I can’t get into mine as it’s seized shut so I’m not sure how I can change anything, if I can’t get into it?

Cheers for the info. The problem seems to be that the drive cables are seized solid. Even after a good dose of WD40, there is no give. I’ve given the roof a good push but, there’s no give due to everything being seized. When fitted, the motor works fine but you can hear it slipping on the worm drive as it is seized. in light of this, I can’t see a way to get into the mechanism to repair or free it up? As I need to be in it on Friday, I may just have to seal it shut to stop it leaking. Im not keen on paying £150 for a roof with a 1-2cm cut in it?

If I can’t physically open it, I can’t really be violent as apart from breaking it, I won’t achieve anything?

I’m open to suggestions but, I need it back on the road by Friday! One way or the other, it has to be back on the car and leak free by then!

There are no drains with this roof, it just fits flush to the bodywork. The roof is seized but, as I can’t get into it to open it to get at the seized bits, I’m kind of scuppered. Also, as the motor no longer has the fixings to screw the motor into, I can’t use the manual wind key to try and open/close the roof although, when I tried with the roof on, it’s was seized solid and it wouldn’t overcome the resistance and free it. It’s not looking good!

Any thoughts on what to do here? I’m confused as to why water is coming in through the sunroof drive motor? My thoughts were, if I cleaned out the geardrive opening and two bolt holes with some brake cleaner so it is free from grease, etc. fill the three openings with Silka or something similar, put a bead of silka all around the sunroof edge just in case it’s gett in there somewhere and the, just refit the sunroof. It would never be able to be used again but, it wouldn’t leak?

Sunroof has been removed but, it still doesn’t help me get into the worm drive and free it up! Also, I’m a bit stumped as to how the water was getting in as there has been absolutely no water entering where the sunroof meets the car bodywork as it was bone dry. The only place the water seems to have come through is where the sunroof motor is located? The wormdrive looks seized so I don’t know how I’m going to sort that out and, as the motor retaining nuts have moved and I can’t refit the motor, I’m not sure what to do?

Yes, I have a shed it can go in. Do I remove all the small screws and take it out that way?

I’m a bit OCD. If I can’t get it done properly, I’ll have to sell it!!

I’ve just been out to refit the motor to see if the WD40 has any effect only to find that the retaining nuts in the sunroof frame have ‘moved’ and I now can’t refit the motor! Ive had a look as best I can but, I can’t see where they’ve gone. I’m guessing that when I pushed the WD40 nozzle in, that I’ve moved them but, I thought they would have been captive? Before I set fire to it, any suggestions?

The drive cable when looked at through the little opening, isn’t looking in that good a condition. It’s quite brown and gunky in there. I’ve just bought a can of WD40 with a nozzle on it and injected almost half a can into both sides of the opening so, hopefully that with help release some of the stiffness? If I do need to remove the sunroof further if I can’t get it to push backwards, can I remove the roof I’m one complete piece by removing these small screws on the edges?

I’ve just had chance to have another crack at this. I’ve dropped the motor down and when powered up, it works fine in both directions so, I’m guessing it’s not the motor. However, when I look in the that the drive wheel goes into, it does look crappy and is wet. Also, with the motor should I just be able to slide the sunroof back by hand? I’ve given it a gentle push but there does seem to be a bit of resistance

If I undo the 2 screws I take it that it will just drop down?

With the weather at the moment, I don’t need a hose pipe!! If I remove the motor, will I be able to just to slide the roof back? Also, with regards to the ‘click’ of the motor when I press the buttons, is the sunroof fault liable to be the motor or, is there some microswitch in there as well?
