OBD2 tool - works with e70 but not e46, any ideas??

[jboy72]

As per the title, I bought an Autophix OBD diagnostics tool to use with my e46 but it can't connect to the car. There is just a linking error. It does however work fine on the X5. I did read that BMWs of a certain vintage had an encrypted data stream but my car was registered in November 2002 and so I am guessing it is not a model year 2001 car (which I think was the last model year to have this 'feature').

Does anyone have any ideas? It's annoying and I assume because this one doesn't work none of them will!

Thanks...

Don't know about Autophix but I've used the Torque Android App and a cheapie eBay Bluetooth dongle with a 2003 E46 330. Worked fine for live coolant temp when bleeding the cooling system after changing the water pump.

It might be that your Autophix system doesn't support the standard that the E46 uses, and only supports later ones.

Thanks for the reply. According to the marketing blurb the Autophix should be good for any e46. However I just read that an aftermarket radio might affect things and I do have a Parrot system fitted so am wondering whether that is part of the issue... something to with k-line wires... annoying! This is starting to feel a it beyond me.

Don't exclude the possibility that you quite simply have a fault.

I had an e36 until recently & although it did initially work fine, at some point the car developed a fault & for most of the systems it stopped connecting.

FWIW my 2203 E46 M3 does not work with with a U380 code reader. it connects but it brings back no codes at all.

INPA however works very well. If it were me I'd either get INPA/DIS or look into getting ISTA ; the newer version.
