Where to get E46 scanned in CHCH?

[mark330i 3]

Hi guys,

My 330i has just come up with engine warning light while driving down the motorway, it still drives fine and I havn;t noticed any change at all in driving. I've tried my cheap obd blue tooth scanner but it won't connect to my ECU..........

Where in Christchurch is a good place to get it scanned so i can see what the fault is??

Sorry if this has been covered and thanks in advance

Yea that's what I'm thinking too, just wanna be sure it's nothing else like minor vacuum leak from intake boot etc.
