The car gives gas by itself, especially when idling.
|
This is probably due to a diaphragm in the maximum quantity regulator in the diesel pump
having ruptured. Diesel then enters the air hose that goes to the air manifold.

The engine runs unevenly.
|
This may be due to air getting into the diesel. Put on transparent hoses before the filter,
and between the filter and the pump (and possibly the pre-heater, if it is connected). Bleed
the filter and pump, start the engine and see if there are air bubbles in any of the hoses.
(Do not drive with the transparent hoses.)

The engine loses power when you give it a lot of gas, and large amounts of brown-black smoke also come from the exhaust.
|
You probably need a new air filter.

The car consumes a lot of coolant, and there is a grey-white coating on the underside of the oil filler cap.
|
The coolant enters the oil; you probably need to replace the head gasket.

Problematic gas pedal.
|
It may be that the sound insulation under the hood has come loose, causing problems for the throttle lever on the diesel pump.
