Engine light
I have a 2004 C180k saloon, and my engine light came on today and it's obviously worried me. I looked in the book and it's either the exhaust or ignition system.
A few times recently it's taken more than one turn of the key to start up so I'm hoping it is something small like the spark plugs, but it has sounded a little throaty of late too.
What is the possible causes? And do you think a complete novice like me could fix them?
I have booked it in to the garage for a diagnostic plug in tomorrow, but £40 plus VAT is annoying.
Any way, any pointers would be most welcome.
Cheers
Tom
thanks y'all
