i expect you are right, i still cannot get the scanner to connect just tried it on my other one, instant connection just a p0380 code came up.. put it on the 110 and nothing except (failure to connect )

it wont work as Neil correctly said, the 406 is not obd2 none of these fault code readers that can be bought cheaply will work with the 406, and that fault code is a 'P' code, p0380 is glow plug/heater circuit "A" malfunction

I'll just add that I only know this because James told me

this is probably the only bad thing about the 406, as the d9 came out in 1999 it was too early for being required to have EOBD2, yet the technology was still implemented i.e. L4 emission control, FAP etc.
the only reason they never botherd with it when the time arrived was because the 407 was about to come hot of the production line and the 406 would have needed to have been rewired from scratch, but as the old technology was so proven they didnt bother
