Error: Lower limit setting for quantity control in AFN

Hello!

I've been experiencing this error intermittently for the past two years:
Quantity setting lower limit entered in the error memory.
I have a Hopa plug-in tuning system installed. Is that the reason, or does it not matter?
Furthermore, for the past year, there has been a jerking sensation when accelerating from low RPMs, which suggests a partially slipping clutch. However, I had a new dual-mass flywheel installed last year (which, in this case, included a new clutch), but the rattling noise persisted.
Could this possibly be related to the fuel injection pump?
Mileage: 165,000 km.

Thank you for your help.

P.S. The workshop wants to take a look at the quantity adjuster. Does that help?

Hello,

It's likely that your device is activating too early in the lower load range (idle state).
Just disable the device and see if the problem persists.

Best regards, Rainer.

I've had this box for 3 years now, and it wasn't like this back then.
More importantly, the question was whether the module was causing this 'lower limit quantity setting' error, or whether there was actually a fault.

Then just open the box, and you'll know.

Yes, Grandmaster, Sir!

I did it, and...
The performance is the same as with the Modul version.
So, the thing is broken! (After two years)
Since I got it at a special price without VAT back then, I really can't send it in for service.
I think I'll install the 10Cent luxury version. This is likely nothing more than this Hopa module.
A standard AFN, like that one, is quite slow.
