I'm new to Skodas and just bought a 2011 Octavia VRS. The Rev counter needle LED was intermittent which was really irritating.
I took it to a company called cartronix in Waterlooville (fortunately less than a mile from where I live)... They replaced all the LED's and refitted it for £190, it took about 35 minutes and now has a lifetime guarantee.
It was done whilst I waited with no prior booking, and they were very familiar with the issue.
It was paid for by the garage I bought it from under warrantee, but I would have happily paid £190 if it wasn't covered under a warrante because its such an overt problem when it's dark!.
