Technical Injector light comes on

[57mmStroke]

Hello everyone!
I am new to this forum and would like to say I am very happy to be a new Multipla owner after looking for one for a long time.
I have just bought a JTD 105 model on a v plate with a known fault being power loss and an Injector light that is constantly on.
Upon picking car up I noticed straight away how weak it was! I stopped for some diesel and put some nice diesel treatment additive I had with me and took her out for a run. After about 20 miles all the power was back but a misfire was felt under constant throttle application whilst cruising in the top gears. I turned the engine off and restarted - Injector light did not come back on. I did not do any further tests.

The following day I replaced the Diesel filter and Air filter (both looked bad).
And at this point in time the light only comes on when it is revved.

I would like to know from your experience what the usual causes for this are (from likely to highly unlikely), and wether this light can only be reset with the examiner, or does the ecu turn it off if it feels that the fault has been found and repaired.

usual suspects are EGR,air flow meter,boost solenoid,boost solenoid to wastegate pipe,throttle pedal...worth getting codes read/diagnostic.

welcome by the way

A bit of an update.
Got her plugged up to an examiner and the following came up:

Incoherence between phase sensor and revs
Diesel pump
Diesel pressure regulator
accelerator sensor 2
main relay.


Injector light does not always come on when you start her up, but comes on the minute you touch the throttle. There is considerable power loss as a result of all this, it feels as if the throttle isn't opening although you are at the end of the travel with the pedal.

Anybody experience the same things? All replies welcome.
Thanks

I have just bought a used diesel Multipla, with 69,000 miles on the clock. I love it ,but my fuel injection light came on and my heart sank as i felt the engine become sluggish. I am worried about what it might be as I don't know any good fiat mechanics in the Cambridge area.

Usual cause of the warning light is a failed injector,they are electronic and require a trip to a dealer as the ECU needs to be programmed to recognise a new injector.
