I had a closer look and it looks like the bumper will have to come off to do it, which is a bit risky. The black insert seems to be screwed to the rest of the bumper with the screws only accessible from the inside, of course. Still, I'd rather pay £21 than £130 plus fitting for the dealer to do the job.
If/when I decide to have a go at it, I'll let you know.
I took the plunge and ordered another set of the cheap sensors from the same Ebay seller. I tried to take the bumper off yesterday, but after 2 hours gave it up as a bad job. Couldn't get at the screws holding the black bumper insert piece in either, so a bit of a frustrating time.
I decided to take the risk and drill through the bumper insert today - it looked like there is sufficient clearance. Took another look on the Hyundai website to get a rough idea of where they should fit. I started off by drilling a couple of 2mm holes. One of the holes seemed to meet a bit of resistance when through the insert, so I had to offset it a little and try again. I then poked a bit of wire through to see if it was accessible from underneath and it was.
I then did the same with the other two holes and all seemed to be OK. Time for the nerveracking bit - got the hole saw and cut the middle two 21mm holes. First one was fine, nothing behind it. The second was a different story, with some extra plastic hit just offset from the hole centre - who would have expected asymmetric bumper internals? I hit the same problem with the other two holes, but to a much lesser extent. Anyway, if I ever need to do another i10, I know exactly where to drill without hitting anything next time!
It was relatively straightfoward to chop out the extra bits of plastic and feed the sensors and wires through from under the bumper and up to the nearside light cluster. The main control box was attached to the light cluster (using the sticky pad supplied), and the spare wire coiled into the gap under the cluster - there's plenty of space to do this. I soldered the power wires straight into the reversing light feed.
The last job was fitting the buzzer which gives the audible warning. This was affixed to the underside of some metal work under the boot box, as near to the seat backs as possible (so that it can be heard). The wire for this feeds up under the side trim, then through the grommet which secures the wiring for the light cluster.
It took a couple of hours, but it's turned out to be a pretty neat job - easily as good as the Hyundai ones (if I do say so myself). When I get chance I'll take some pictures and post them up, then you can see what you think.
