Quantity adjuster

Sorry if this is redundant, but I couldn't find a reference to it anywhere.

Code 01268 Quantity Adjuster (N146) 18-00 Upper Limit?

Wadayawanna know? It's the thingy in the pump that controls how much fuel is injected.

Search for threads with "QA"

I have that code and the check engine light and the blinking glow plug light, but the car runs super...wondering if there is need for concern.

Not finding much on the search.

Is the code set again after clearing it? Immediately, or only under certain driving conditions?

Replacing the fuel filter would be a good first step, especially if due. Also check for damaged or corroded wiring/connections to the injection pump.

Yes it sets right away after clearing it. Thanks.
