on the tools recommended thread I rec'd an ELM327 wifi interface for fault reading looking at fuel trims etc,

anyway I got one from ebay (someone had used one with his iphone previously on my car and it worked fine)

so when I plugged it into the car I ended up with a high pitched squealing noise from the ecu area , the suspension is showing a fault (it thinks that a door is open so will not change height ) the interior lights don't come on with doors opened, the central locking doesn't work, and my iid tool no longer is recognised.

I have tried a hard reset , ie battery disconnect and leads touched together , still the same .....

oh dear!!

over to you guys for any thoughts/help

5a fuse in the glove box... Check them all though...

Sorted - thanks very much, panic over - thought I'd destroyed some of the cars brain

Which ELM327 did you get? Or was it simply a case of accidentally shorting some pins when you plugged it in?

FWIW mine looks like this (but it doesn't have "Made in China" on the sticker, and it has a bluetooth logo before the OBD)

Probably a chinese rip off for 13 quid on the bay


will try it on the sons bmw , later , he's away for a month or two , so any disasters and it can be fixed in good time.

which software are you using ? and did you have any problems setting it up

heres a link to the one I bought (wifi version)
