CLK 230K W208 facelift
I've had my 1999 CLK230K coupe (facelift model) for 8 years and I'm still delighted with it. However, with 110,000 miles creeping up I'm wondering whether I should try to solve the bag-o-nails noise I get when starting. It's been like this for the last 3 or so years and not getting any worse. To be honest, I don't even notice it when I start the car with the doors and windows shut. But if I'm nearby when 'er indoors takes the car out, the noise sends a shiver right down my spine. I took it to the local German car specialist a year ago and he charged me £45 to grease the starter pinion and flywheel ring gear. This made it a little quieter at the time, but it's now just as bad as ever. Any suggestions?

Hello and welcome :D:D

The idler gear on the front of the engine can make a noise,,as can a timing chain, or valve gear.

Would not it be worth just leaving it over night with an indie who could start it up and know instantly what it was

The other cause can be a leaky exhaust manifold that quitens as soon as it warms up a little.

Thanks for the answers (and the welcome). Sorry, my description of the noise was clearly lacking. It's literally only immediately on starting when the engine has sped up enough to throw the starter pinion back. It lasts less than a second but sounds awful.

Perhaps your starter pinion isn't disengaging properly - hence why the regrease in the past has had an effect.

Its the flywheel that needs greasing with special mb grease.
