Fault 2135-004 Glow Plug Cylinder 3 Open Circuit
I have the following fault code on a W164 :
2135-004 Glow Plug Cylinder 3 Open Circuit
2133-004 Glow Plug Cylinder 1 Open Circuit
Issue returns after codes erased.
Do this mean the plugs require replacing or other issue?
Thanks
Today the dealer replaced the glow plug relay and declared the vehicle to be repaired. Hope so.
Also, replaced part has some improvements due to part # is not same.
You shouldn't have any issue with module - as for glow plugs, you need changed them as sparks
