The pitting of the exhausts is a hallmark of every car on the MQB platform. S3 has it, TTS has it and Golf R has it. Each trim is around £60 each. Mine are bad as well but from a distance they're OK after a scrub. I did think about just painting them black but to be honest, but I prefer chrome tips so you can actually see them. I'm going to contact Crewe Audi online as they generally do a decent discount if you email them.
Only thing I'm worried about it getting them off. It's same drill as the tips on BMW's M cars, with the prongs holding them in place but apparently they're a real bastard to get off.
At lunchtime today I did a bit more digging on my auto-hold button and I've fixed it.... kind-of. I'm convinced that there's a fault with the button itself (for various reasons), so having looked at everything else, I came across a thread on an RS3 forum where guys were coding in the Auto-hold feature without the button (basically so that it's on all the time and you can't turn it off). One guy mentioned that in order to stop the car throwing a fault on the dash due to the lack of button, you need to change a coding option to tell the car not to check on the presence of the button itself. So I did this, and lo and behold everything now works, with no fault codes....
...however, although the button still works, the indicator lamp on it isn't behaving normally (it's permanently lit, albeit a bit more dimly than the (P) button above it, regardless if auto-hold is switched on or not), so I'm convinced that KUFATEC have sent me a faulty button as part of the kit. I'm waiting to hear back from them, but I can live with it in the meantime.
With that conquered, I moved on to my other outstanding job tonight which was to see if I can sort out the wobbly spoiler. The issue is that it's cheap and hollow, so with the lack of rigidity it wobbles slightly when driving. I think
@Denso 's was worse than mine, but its still enough to annoy me. So my theory is that I can increase the rigidity by drilling a few holes in the underside and squeezing some Tigerseal in. The idea is that the Tigerseal will form pillars inside the spoiler that bond the top and bottom together and in turn cure the slight wobble at high speed. Having done all that though, I;m not convinced it's going to work. I think the main issue is that the uprights aren't firmly against the bottom of the spoiler when screwed in and that's allowing both ends of the spoil to pivot a bit.
If it doesn't work, I'm going to live with for the time being as it's not terrible and I can't be arse shelling out for the cost of a new one and painting as well.
