My drivers side mat has just the single fixing hole which marry up with the supplied (in the car) fixing peg. It’s different to the one shown in that link above although still oblong, no pic I’m afraid.
Hmm, I bought a spare set of correct mats with the logo for my NC Niseko and the single fixing strap was included with the instructions in a smaller bag inside the sealed bag with the two mats. This flat strap with the knobble sticking up is anchored by a screw in the cross-member under the middle of the driver’s seat. No fixings for the passenger side, although there is also a single screw waiting unused in that cross-member.
Edit. Here is a photo of the strap still in the bags.
I think there is a difference between a Mk3 and a Mk3.5, I have a Mk3.5 and it is fitted with the 4x round mat fixings that the OP is looking for, I believe if you have a Mk3 then it only has the single centre fixing, couldn’t say if it is round or rectangular as never looked that close but I know the mats between the versions of Mk3 MK5 have different mat fixings.
The clips [Part number C830V0329 four contained in pack as your photo] fitted my MK3 NC mats with round holes [2Nr in each mat] exactly. If you feel the fitted carpet infront of the seats you will find there are pre-cut indentations for the clips to be fitted, you will need a stanley knife to open the indentations to take the clips through the fitted carpet.
I obtained my clips from S Jennings [Dave Garth] in Stockton, Cleveland [01642 632200] for the princely sum of ÂŁ3.96 inc. of VAT and Postage. This was in Feb 2014 so the price may have gone up.
If you require the fitting instructions please PM me with your Email and I will forward to you.
so I have now acquired two of the offending clips.
looks like they feed through a slot in the carpet and then the two halves clip together somehow with the carpet in the middle.
have found two pre-cut slots in the carpet which will probs need opening up slightly to take the clip.
stand by for progress when I have the email from TT with how the clips are supposed to work and whether I need to make more holes for the clip catch to get through.
