Stupid question of the day - so forgive me.

My TT has developed an intermittant fault with the windscreen wipers - if i try to activate them there is a clicking noise coming from under the bonnet - and no arm movement. Best guess is a motor fault or a sticking relay somewhere. This is not helpful as the MOT is booked for Monday.

In my enthusiasm to sort it myself I have tried to removal the Scuttle panel - but before doing that you need to remoce the wiper arms - and here is the problem. The wiper arm nuts are covered by plastic covers recessed into the scuttle. The centre cover I can remove quite easily as there is a cut out you can use to lever off the cover with a small screwdriver. The left had one though seems to be so deep in the scuttle that no small screwdriver will reach in.

So... two questions - any one got any bright ideas what the fault with the windscreen wipers might be ? Am I on the right lines that the motor has failed.

Seondly how to get the left hand cover off - short of grabbing it with a mole wrench and wrecking it?

Thanks

Best way to verify faults is with an OBDII diagnostic device. Otherwise trouble-shooting is just a guessing game.

Many forum membershave either VCDS or OBDeleven. I have both since I have a Roadster and the VCDS is the only device that can sort the Adaptation for roof failures.

For quick scans and convenience (mine lives in the glove box), the OBDeleven IMHO is the way to go. More here -

On a side note I've seen many mentions that to pull the wipers off after taking the nut off you can just rock the wiper arm back & forth and it'll come off. Yeah I tried that before, never worked. Wiper arm puller is recommended IMO. When I needed to get those things off (on A3 but virtually the same wipers) I just gave up and put the nut back on and just got to the things by flexing up the panel lol. Granted that was just to replace the struts, not to really get under there for the wipers and drains and all that.

I do have a battery terminal puller that would have done the job most likely but would have chipped/scratched up the paint on the wiper arms, surely causing rust later. So I just left it alone. Pretty sure the factory tool (or similar) to pull the wipers does so such that it doesn't damage the arms.

My post includes an arm puller (see below) which is very similar to the VAG one but way cheaper and gets the job done.

I have this one. It works, but it seems like it could break with every twist. I'm working on the principle that it could be a new one of these pullers each time I need to pull the wipers.
I would recommend some wd40 on the nut before you start, to try and not break those pullers.

They do make heavy-duty wiper pullers but their size (thickness) makes it hard to get under some wiper configurations. Best thing is to use a good penetrating oil like Kroil or PB Blaster and let it sit for a long while. WD40 makes a penetrating oil under their "Specialist" line of products but that is different than regular WD40 (the later being a poor penetrant / rust / corrosion buster).
