1998 Fiat Hymer 2.5 td low on power

[Staverh]

Hi.
I have a 1998 hymer fiat 2.5 td that is low on power and have red light at the dash.
Symptoms:
Light is gond and motor runs fine for 0,5 sev every time it starts.
Was fine for one week then error came back.
checked timing belt.
Anny ideas?
does it have obs port? Can not find it...

Also, the red light has no symbol on it...

Picture of dash? We might have the symbol?

Check obvious?
Earth straps
Air filter
Pipes from and to air box and intercooler and turbo (?)
Water drain from fuel filter (and how old is filter)

Hi. The lamp does not have any symbol. Checked air filter, and fuelfilter. Piping from turbo to manifold is also checked.

Earth strap?
Just trying to imagine under vibration a loose connection will make power to fuel pump stutter?
I added two extra earth straps to mine. Extra one from battery to chassis and extra from engine block to chassis.
Notoriously poor on older Fiat's.

Lack of power.= Fuel poss
If it's like mine 1998 Hymer 2.5tdi
There is a filter at the end of the pick up pipe in the tank.but no light in dash .
Clogged fuel filter maybe.
Was the last I thought if after changing filters and checking system.
All fine ,but caught me out pulling away on a hill in Spain or when needing extra revs .
LHD panel in floor under mat,a few screws
Then a series of 6mm nuts ,carefully lift out sender unit.
Filter on the end press and turn to get off . I washed off with a toothbrush and tfr .just years of accumulated muck in diesel.
Not had a problem since.
Another is although fuel filter could look ok it lets you down in the same way when extra revs needed.
Hope this helps

Hi. Earth strap looks realy good. This is a pucture of the lamp. Checking in tank filter now.

Can't get to MH to check what I have in that position but someone else here might.
Interesting that you can see your glow plug light (furthest bottom right). Mine illuminates so quickly and off again there was no way i could catch it on camera.

Motor is not running at the picture. Running now
Have also checked intank filter. It was a bit clogged. But same error after cleaning.

 

[Jev88]

Have you checked running with NO air filter? Does light go out?
This could also be brake pad warning light.

Turbo waste gate valve possibly stuck?
