04 2.2 Diesel - glowplug warning light problem - Chris xxxx
Can anyone help with this?

Sudden loss of power accompanied by coil glowplug warning light coming on. AA could not identify the fault, so recovered to Honda main dealer. No diagnostic code - they checked the fuel system and replaced the diesel filter (which was in back to front), checked (but did not dismantle) the exhaust / cat and then tried a replacement ECU. Nothing found - they said it was OK to drive home but the fault would recur - and it has. Will not rev above 2,000 and there is some sort of power limiter which means the speed dies away on an up-slope. The car has not been misfuelled

Any ideas as to what this could be? What to try next.....

{header corrected, as OP confirmed it was the glowplug light and not the coil warning light - DD}

Do you mean the glow plug warning light if so it is initiated by a faulty EGR,turbo plus one or two other things like a faulty glow plug.

Your correct - the glow plug warning light.

Sounds exactly like what happened to me when my EGR went. They are expensive, so Honda tried everything else under the sun first (was under warranty). Replacing the EGR fixed it completely, and new software (there was a TSB apparently) has so far stopped it recurring (50k miles since the change).
