My Merc E200 estate 1997 has developed a problem. The indicator lights stay on instead of flicking on and off. The mechanic says I need a new part (called a "sun" ?) costing €400 for the part only. Any ideas how I can fix this?

Fairly sure it's Relay N10, part number 140-820-76-26.
Behind the fuse box in the engine bay there is a cover held on by (I think) 6 screws.
Remove this plate, give N10 relay a wiggle and a couple of sharp raps with the handle end of the screwdriver, now try indicators.

Price of 400 euro probably about right, but shop around.
Worth getting the relay opened and checked by someone who is competent with electronic circuitry and components.
I take such things to the local TV repair man. Quite possibly sticky contacts (self-welded) or a poor solder joint.
Hope this helps, please post back the outcome.

any indicators not flashing is caused by the failure of the cars flasher unit,phone a merc agent and ask for the price of a flasher unit and ask where its located on your model.
find the old flasher and change it along with mechanic you are using the word rip off springs to mind.
