Disconnect the battery for 30 minutes.

You only have to disconnect the -ve terminal and for about 20-30 mins.
Have your radio code handy or aftermarket instructions to sort your presets out
Once connected back up turn the ignition so that the dash lights are on and leave for about 5mins or until all quiet from under the bonnet. Can't remember what is happening but it whines for a few mins.
Then you can start the car as normal.

Oops didn't read it was for the Golf but I'm sure it will be similar.

cool, cheers allan, its prob resetting the throttle body when it makes the noise,

will give it a go,

sorry guys but i think that 3-5 minute throttle reset doesnt work, only through VAGcom.....

nev,....its not been said, the engine needs to be warmed up then disconnect the battery..when all connected back up, as allan said turn ignition to first position...now you have to make the car re learn everything.fold in mirrors then fold out, turn climate control on, then off, electric windows up down (the one touch function takes 5 or so up and downs to relearn).....now you can blast the seven shads out of it.....(thats why you pre warm her..)

cheers bret, she is on her way home with the car now so will give it a go.

Never had to make my car re-learn anything at all when i replaced the fused board on the battery.

 

[DOLBY]

cool mate, scared the shite outa me when i did mine.....boost was throwing me all over the place....lol....most peeps do this (including me) once a month or so,

 

[DOLBY]

some cars differ mate...if you think about it ...disconnecting the battery for half an hour will affect the electrics one way or other, thats why i do the windows routine always.....

 

[Nev_LCR]

the golf hasnt got that much to sort, no climate or folding mirrors, just the windows,

i know one guy local has a rally style battery shut off switch under the bonnet for just the purpose as he does it so often

his words 'saves time messing with it when i get it back off the mrs for the weekend '
