M271 warning signs

[markwibbs]

Can someone please list the warnings signs of issues?

Bought a 2007 CLK 200K yesterday which misfired on a warm restart. Car has full MB history, recent service and 45,000m. Restarted perfectly. Had been on near 200m run with 1 stop.

Much appreciated.

- Oil in loom (on either of the two camshaft position sensors)

- Split vacuum hose under air filter box

- Blocked engine breathers

- Premature timing gear wear

These are the typical M271 issues.

But of course you'll need to read the fault codes before taking this further.
