Bit of a pain each time you start the car though

Both my cars do it. My life would be fine if they didn't
 
looked around on the internet for a while, seems like it could be done if you know how to re-program the cluster or ecu. In newer cars you would tick an option somewhere in vag-com called staging and it would do it.

would probably need an external module for older cars, like the "happy light show" one they use on the Astra. seems like nobody has done it/made one to sell for the older leons or golfs. but there was a thread for mk4 golf's showing a lot of interest on the uk-mkivs forum, still seems like very few have bothered to do it though.

would look cool, but too much hassle i think.
