I have aquired a 1990 W124 300TD with 302,000 under it's wheels.

There are some jobs to do.

The glow plug light stays on after it has started and it initially runs on 4 or 5 cylinders, smoking well all the time, for about 10 seconds before settling into a smooth (for one of these) idle.

Warm starts are perfect.

Would that suggest just inopertive glowplugs, or should I be looking elsewhere in addition.

Thanks a lot
 
Hi

That suggests a duff plug or two

They are easy enough to change if you have a flexi ratchet ring spanner.

You can pull the plug off the heater plug relay and test with a multimeter to see which ones are duff, the plug is numbered 1-6 so just change the offending plug/s.

Hope that helps
