Hi All

 

New member here although often read posts before joining. 

 

I'm hoping someone can help , and this thread may help others in the future , as this appears a common problem.

 

Not only is it a common problem but one that appears in exactly the same place for a few people. My Karoq has a panoramic  sunroof fitted but it appears to be leaking. I've seen 2 other posts where the leak is presenting itself in the exact same place. It's dribbling through a vent facing down in the boot , directly above the rechargable torch. I've also noticed a damp mark on the corner of the  roof lining , which is a bit further forward. Strange how this leak is so often in the same place.

 

After carrying out a water test , all  drainage outlets of the sunroof are working except the n/s/r , as I expected.

 

My first thought was to check the drainage pipes weren't blocked. After eventually finding the bottom outlet behind the wheel arch water guard  I proceeded to use net curtain wire to check it was clear. To my suprise the pipe is perfectly clear and clean. However , it does "dead" stop at the top. Now Im suspecting that this pipe has come off right under the roof lining where it meets the cassette drain , although I don't know. It could be split.

 

I think I need to start removing interior trim to get to this , which from other reports sounds tricky. Does anyone have any experience with this issue , what was the outcome and did you need to remove the internal trim ? 

 

My car is under Skoda extended warranty but I note that sunroofs are excluded , plus if I take it to my dealer , they'll want some decent money just for diagnosis.

 

2020 Karoq Se L

My 2020 1.5 Edition is displaying the same symptoms. I thought it was something blocking the drain hole in the tailgate. I would be interested in any other comments members have.

Sorry can't help guys and I suspect the only way you will find out is to drop the headling.

 

After owning two VAG cars with Pan Roofs and having issues with each I'll never have another.  It's why this Karoq is an SEL without panroof.

 

The last repair I had cost £2500

So here's an update ....I managed to drop the rear head lining down enough to slide my arm in and reach the suspect drain hose .....oh boy ! These drain tubes  pull on and off so easily , hardly a tight fit , they just clip on with a mild push.

It was attached , but I removed it , blew down the tubing and reattached it again. 2nd water test from the sunroof gulley  and the drain was now flowing , result !! However during this water test I got clumsy with the water , and some  went over the roof and around the rebate for the boot , this ended up being a bit of luck because  my partner  noticed the rubber grommet holding the wires from the main body of  the car to the boot was also seeping. A bit of flexible sealant and this is now all sorted. 

 

All a bit odd as the near side corner drain certainly wasn't flowing. I genuinely think this was leaking in 2 different areas.

 

By the way , Dr Beckham's carpet cleaner did wonders on the roof lining , cleared up the water tide marks and other marks too. Just agitate it in to the liner with the bristled cap , expected some to drip as your working upside down , leave for a few minutes and dab with kitchen towel or spotlessly clean MFC  to remove some moisture after.

 

Also .....trim removal was a pain in the butt , and I can see that without patience and care you could easily do damage. I had to start with low level trim first as the pieces are "layered" over each other 

 

Well done. Are the rear drain holes at each corner and are they visible? From what you have described it seems you can only access them from the inner wheel arch or by removing the headlining.

The lower drainage holes aren't visible but if you look at the attached photo , you can remove these three torx screws , pull back the wheel arch dirt guard , and then reach in with your arm. You can feel them rather than see them. Alternatively you can remove the wheel and remove the whole wheel arch guard.

Is anyone able clarify if the front drainage tubes are also behind the wheelarch liners please. I don’t have any leaks as yet, and bought a tool off Amazon for clearing the drain tubes, it’s a long nylon rod with a ring at one end and a tiny bristle brush at the other. I’ve used it on the front drains but didn’t realise there were rear drains too. Being able to see the brush has gone right thru the drain tube would be good.

@logiclee Thanks for the diagram.  The nylon rod tool with a bristle brush at the end goes down the front drains easily and then comes to a stop, which is probably when it hits the wheel arch liner.. I located the approximate 'outlet' position by pouring a small amount of water down the drain tube with a bowl under the car to catch it. Its approximately 8-10 inches in from the edge and in line with the mudflap. The rear drain looks impossible to access with the roof right back. can it be accessed with the roof forward and tilted up at the back or is the only way to clean the rear drains from the behind the wheel arch liner so going up, which would be less effective as it will push any sediment back up ratherthan straight out.
