[s-cars] Blown ECU 15A Fuse

[James Murray (QB/EMC)]

Unless your car has extra chilli peppers from down south consuming more
power... Then 5amp fuse will do... I can't see that little ECU consuming
up to 15amps! 

A 5amp fuse was in my car, and when I posted way back I got responses
saying the same and that Bentley was wrong to publish 15amp. My car's a
93, so either Audi upped the fuse rating or it's a misprint... I don't
know, but I feel safer with 5amp fuse.

J,

Uh oh.  I'm pretty sure the one I pulled out of there was 15A. It's at
home so I will check when I get there, but it sounds like you are sure
it's supposed to be a 5A, not a 15A.

I put a new fuse in and it hasn't blown yet, although I have only driven
to work since the event. My POS's are original, as far as I know at
least. So a failinig POS could also blow a fuse when it starts to go
South (of dee border senor, insert tilde symbol over the n and talk like
a looney tunes character with a bad mexican accent)?

Hmmmm, zoinkies, I'd better call the gang from Mystery Inc (I've been
watching too much Scooby Doo with the kiddies lately).
