"Selespeed system failure" flash then death
So this is the second time this has happened to me now.
Driving along all happy, slow down to traffic lights, "selespeed system failure" flashes on the dashboard and the engine cuts out. Turning ignition key does absolutely nothing for about five minutes. Five minutes pass, (much beeping from fellow motorists) turn engine key again car starts up and runs like nothing has happened. In fact it drives like an absolute dream. Any ideas guys?
Things I've checked from doing research on this forum:
Pump makes noise every time I open the car door, makes noise for less time if door openings are close together.
Selespeed oil level checked and it's fine now, however I must confess it was low last time this happened. I topped it up then with D111 oil.
Many thanks in advance
