C320 engine warning light

[warrens]

Hi guys looking for some help again.
I changed the fuel filter on my C320 CDi yesterday as I have done before with no issues, however this time after a short time the engine warning light came on and the engine has no power as if it may be in limp mode???
The filter was primed as usual as I have done before but this time the engine is flat and won't rev 40mph max and takes for ever to get there!
I checked the plugs I had to remove to get access to the filter and all the wiring seems good and tight.
Only difference this time is I may have had the ignition on, will this have caused a fault with the Air Mass Meters I had to unplug?
Any help will be greatly appreciated

Thanks in advance

No it should not have. The red seal on the turbo intake didn't get kinked going back on did it?

The seal was replaced when the filter was changed, the one that was took out was split and had a small piece missing

I can't really see what else could have been dislodged. To prime the fuel up the ignition just has to be left on for around five secs before cranking. What about the small sensor on top of the passenger side air cleaner?

The bleeder valve hasn't popped out of the air trunking? This is the sensor in the trunking near the turbo intake

Hi all connections were checked and double checked, pipe just in front of turbo inlet is in position, it's really got me stumped,,,

I think it's going to have to go on a reader to see what codes are showing to see why the engine warning light is on??

It's the only way. If everything you have checked is fine then a star check is needed.
