If I remember correctly, W does appear on the dash. Your car is still under warranty, suggest booking the car in with a dealer.

Firstly and the obvious is there water in the reservoir? Other than that it is most likely blockage along the tube to the rear washer.

I know nothing about tow bars. If you are on Facebook joining one of the GS group will give you information on towing as a few members on there have experience. Witter tow bar is a name that came up all the times.

Glad you got it sorted. That is a lot cleaner than mine.

No I didn’t remove any wheels at all. The rear ones are abit fiddly as you have guessed the lack of space. I have a little horizontal ratchet screwdriver which is only 10-15mm tall plus the length of the self tapping screw is small enough to fit the space behind wheels. Taking the rear wheel off will be much easier to screw in though. I too have a some metal clips. Without instructions I just clipped it where I thought it was a good place. Taking photos is not a problem but posting on here might be. I will give it a go later if I can.

I have genuine mudflaps on mine and you do need to drill holes. You just to have line up the mudflaps and drill the holes.

The plastic is quite soft and I just used the self tapping screws provided to make the holes whilst screwing it in. I didn’t even take the wheels off.

The fuse box is on the side of the dash. Open the driver door and you will see the panel. Remove the panel and you will see the fuse box.

There are many GS owners online and you just need to know where to look. Most favour Facebook these days.

2017 Q4 map still not the most up to date but you will have to make do with it. If you are on Facebook, there are 2 GS groups on there that are much more active than on here.
