My engine started making a worrying sound a while back. There's a kind of tick which is audible at light throttle from around 1400 to 2000 rpm.
First sign of trouble came at startup after the first time I changed the oil and filter. There was a loud knock from the engine bay two times...
Ok, here's the deal. I have already replaced the module controller to accommodate the new metallic glow plugs 3 years ago. Do I need to replace the module controller every time I have a glow plug go out?
**And when one plug goes out I do go ahead and replace them all. :)
