I've bought a cheap ODB2 wifi reader. It seems to work fine in the gf's ford ka, however when I plug it in the S it can't seem to lock on a protocol, the apps just loop through all protocols and nothing comes back.



I have a 02, anybody had success with a similar setup?

 

I've used one of those cheap adapters before and it could take up to 10 times of plug in and out before it finally connected.
So try that
