I have a K Reg 110 CSW, 200Tdi.

The first sympton I noticed was when starting. I would turn the key to
the on position and hear a relay or two clunk as expected. After the
glow plug wait, as I turned the key from the 'on' to 'start' position,
the relay(s) would momentarily click off but it would start OK.

This weekend however, the engine started to cut out when running, either
straing after starting or anytime after. The engine runs fine and when
it does cut out it stops dead, no spluttering, and restarts straight away.

Tinkering with the ignition key it looks like there is a dead spot at
the clockwise end (towards the start position) in the 'on' position at
which all the electrics are swicthed off. If I back the key off towards
the 'accessory' position without actually turning off everything is
fine. I drove home for two hours like this yesterday.

Has anyone else seen this failure mode? It seems to be getting worse, so
I'd better fix it. Or has anyone been living with this quite happily?

I'm guessing the fix is a new steering lock/start swicth assembly (30/40
quid - part number anyone?). The current one has (logically, really)
been fitted with tamper proof bolts and which will need drilling out.
Anyone know what diameter the bolts are. Aby other comments or advice?

Thanks for all you help.
