well think i need a new voltage stabilizer in dash. so have read up a few forums and thoght i could get one at maplins but no they dont do one. did ring vw but the guy i spoke to didnt have a clue what i was on about. so i hung up. any way i think ive found some after a lil reserch. for 50p. only thing is the pins are at the opposite ends so will have to put it in up side down and a washer to pick up space to reach heatsink if know what i mean. any way item number ( kca 7810 )at http://www.farnell.com" onclick="window.open(this.href);return false;
you all prob know this,

Not only do we know it, we're already discussing it:

Available easy enough - pity you don't need a 7812 - I've a bag of 50 sitting on my workbench! I would make sure that you get a 1.5A one not 1A to give you leeway.(I don't know what rating the original is)
Plenty on Ebay.

For those that did not know this, it works fine. I have used that trick more than once on various VW's

Here is a link to the actual thing = http://uk.farnell.com/taiwan-semiconduc ... dp/7174020" onclick="window.open(this.href);return false;

E D I T = if easier they are on ebay too as = http://www.ebay.co.uk/itm/TAIWAN-SEMICO ... 3a6f615068" onclick="window.open(this.href);return false; tho at £1.99

The only thing against those ones is that they are the 1A variety not 1.5A.
Ebay http://www.ebay.co.uk/itm/L7810-7810-Vo ... 3efd078e5b £1.95

Good point - I will C&P that onto the other thread.

Wonder how much current the fuel and temp gauges use, best to err on the safe side tho :)

I don't know either that is why I suggested use the 1.5A - I couldn't find a datasheet for kca7810, assuming that was the original part no..
