Hi there, my t6 coil light came up on dash last week on motorway, luckily 5 mins from home. It's been in with mechanic today and he's informed me it's a faulty fuel injector. He's the go to guy on the Wirral for transporters and I've heard nothing but good things about them so fingers crossed that's all it is. Still not much change out of £700 after labour. I'll come back to this thread to let you know how I get on.
