Hi all, I am trying to find out how i can remove the ECU from my dads 206. We have got the front bolt off and the front part of the ECU seems to move free but the rear bolt we are unable to get to as the tight space Any tips on how to get this off so we can check the earth cable under it Chris

There is a single nut at the front which holds-down the whole plate
ECU bolts onto that with another two nuts).

Undo that and the whole plate slides-out with the relay unit mounted underneath.I would remove-reinsert the ECU connector(s) but don't use contact spray on there.
Careful when removing as the have a dual locking system with a 'finger'-key as well as the big lever 'bracket' around the connector.

The relay underneath has a Bosch type locking-connector,
unplug it and put some contact-spray on the pins, but not WD40.

There is usually another thinner (yellow?) cable mounted on the gearbox near the main earth-strap from the battery, that is the ECU earth.
Also check the +ve connection which goes to the fusebox on the right.
It should be firmly bolted and with no rot, battery and fusebox-end.
