Hello and Welcome to justanswer..

Im afraid that while the indicators may seem a simple enough issue - on these they are not..

Your problem is either, the switch unit itself - on the column - or, the Bsi unit - computer control module..

Try disconnecting the battery for 30 mins and re connect and see if that will cure it - it will often... If not there is whats called a Bsi reset procedure you can try which I can give you if needed...and if that doesn't work, then Im afraid its diagnostics time to trace the fault...

Im very pleased to have helped you - Let me know if I can help anymore...

Hello again - thank you for your reply...

Indeed- Peugeot's / Citroen's and the like - terrible for electrical / electronic gremlins - most everything needs diagnostics and are usually expensive to sort.

So - I will give you the full bsi reset procedure ...see if this works.

If it doesn't - you really are left with no choice but to get garage help .

Ok so here is the full procedure for you Paul....let me know how you get on..

Put the driver's window down, lift the bonnet and ensure all equipment is switched off.

Ensure all doors are closed and remove key from the ignition.

Wait for 3 minutes, disconnect the vehicle battery and wait 15 seconds.

Reconnect the vehicle battery, wait a further 10 seconds (do not open doors.).

Switch on the side lights through the driver's window.

Switch on the ignition and check system's functionality.

Hold lock button on key down for 10 seconds.

Remove key open & close door test central locking system.

Start the engine and complete the system's check.

Failure to follow this procedure could result in incorrect operation of many BSI related item.
