MercE200 cdi 2011 130bhp engine W212 - Glow Plugs - Matt Kerrigan

Hi

Just wondering where are glow plugs on this engine and what are they like to change. How can I test to see if all are working. Trying to chase a slight intermittent shudder(every 10 secs approx) in engine at idle only when car is cold just after start up.

Appreciate any help

Thanks

The glow plug circuit can be tested via the diagnostic system,along with any fault codes logged on the engine control system.Access and replacing glow plugs on these is not a job for the inexperienced.
