went to jacar 1.00 for a 3mm white led (think i could of used a 5mm one but didnt realise until i put this in

had to buy a new battrey the original is a 1.5 v alcaline and the leds run on 3v
i got a cr1616 lithium coin battery which has the same diameter as the old one it is just a little thinner
trimed the legs of the led and bent the positive leg at 90 degrees and sloted it into the coper contact part
i trimmed the negative leg a bit shorter and put that between the spring and a small pice of plastic and it wedged in there nicley
put it back together and it worked perfectly
and no soldering

Gave this a shot with a 5mm LED. Had to file the LED down because it didn't really fit.

Still I think the bigger 5mm is worth it cause it does light the room like a Christmas tree. Also placed a cover over the negative wire to ensure it doesn't contact anything it isn't meant to.

The copper negative contact to positive spring arrangement is not the best design so I added some electrical tape to the edges (not shown below) to hold the battery in the correct position and provided consistent contact on hold. Otherwise it moves around to much and doesn't connect perfectly every time.

See photo's below. Thanks to redgtd for the great idea!!!

I choose blue because that makes this blue tooth enabled right?

that looks awesome may buy a 5mm led and put it in. it does look better and brighter

Bump, just done mine, can i reccommend getting the 3mm LED, as i spent ages filing down the 5mm one to fit, and even then it does not fit well.

i would not get the clear white colour, as i don't think it provides as much light as a Blue or other colour.

and the cost of a new one was $70 according to VW australia
or i found one on ebay http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT

I love this thread, this to me is what forums like this is all about, that is ingenious, so much gain for very little money and effort! and a big F U to the Stealers!

Goldstar for Redgtd!!!

Hi all,

This is certainly a great thread. I think this repair/mod would also apply to the MK4s as well, I know that key looks a lot like mine and my light isn't working either.

Thanks guys

Pete

$70 is the cost of a whole new key, not just the bulb. (Of course it's then lots more to have then thing coded to work with your car (if you need it)).
