Hi does anyone know if the peugeot 308 support ELM327 bluetooth diagnostics device and where you plug this device in. i amd thinking of buying software for my mobile phone and buying the ELM327 OBD2 bluetooth device
1) Yes, but only for the engine - you won't be able to access ABS, aircon, or on board system trouble codes, or alter the vehicles configuration. A simple £10 OBD device will give you as much utility as an expensive one.
2) Pull out the tiny rubber mat in the cubby under the centre console, and you'll find the socket there.
