Intermittent startup

[Kashubiantyke]

Hi there. I have a C-class Coupe C220 CDI with 90,000 on the clock. When I turn the ignition key to start up the car it sometimes turns but nothing happens other than a click. All electrics work fine. Took the car to a dealer who checked it over with the computer diagnostics. No problem was found! It is an intermittent fault. Sometimes I turn the key and the engine fires up instantly. Have been quoted between £500 and £700 to repair the ignition switch!!! Anyone out there had similar difficulties. I would greatly appreciate any advice.

That sounds like the beginings of an ignition switch problem.

Is the battery good?

Are the key batteries ok?

My Electronic Ignition Switch went the same way a year ago, only solution was to fit a new EIS. The new switch cost from an Indie was £450ish including fitting.

The switches arn't the type of device that can be repaired to my knowledge and the new switch has an activation 'green key' so not a DIY project.
