P38 Engine 2.5 DSE issue on changing gears - injector light on

Hello guys,

My p38 2.5 dse, when changing gears, for ex. 3rd to 4th gear, when the rpm drops, the injector light turns on I change to 4th and the car doesn’t accelerate and keeps the light on. If I change again to 3rd, the rpm increase and the engine keep running normally.
It happens more often with the cold engine.
I have the following dtc that are intermittent:
01 Fuel quantity control unit in pump
05 Sensor injection start

What do you think would be the issue?
Pump eletronic? 4th pilot injector? What else?

Thanks

If pump timing is out it will throw those sorts of issues as an effect but not necessarily a cause. Doesn’t mean your pump isn’t duff or in need of maintenance. More info needed

What diagnostic device are you using? Hawkeye for example is a generic LR device but not reliable for P38 diesels.

Is this a diy thing or are you paying a garage ?
