Glow plug light warning is on. Researched forum to find DIY replacing glow plugs but only found 2006 model DIY information with needing 30 minutes to do. My car 2007 bluetech with 54,000 miles. Do I need to replace all 6 or just the bad one. Does someone have a illustrations in removing parts to get to the glow plugs. Thank in advance.

 

If you are going to attempt to do this kind of work on your car I would invest in the STAR Service manual Library. You can order from MBUSA for about $100. Mine covers Model 211 up to model year 2008. Part number is P-2700-211-07.

And for replacing the glow plugs. Do them all and save yourself additional work in the near future. I have seen these plugs start to fail around 50-70K miles and once one has gone its a safe bet another will be close behind.
