Wear and tear in the crankcase and/or power train. Your car is talking to you about budgeting for an expensive repair coming up.
knocking noise
if it sounds like the knocking is coming from the bottom of the engine i would bet it was the rods or rod bearings may be worn. if the knocking is on the top ,then i would have the lifters and or the rocker arms checked.

A knocking noise when pedaling a bike could be caused by loose pedals, a loose crank arm, worn bottom bracket bearings, or a misaligned chain.
i don't know if it helps, but my '99 legacy outback was making a knocking sound. turned out that the oring on the brake caliper pin had worn out, and the pin was kind of knocking around.
Usually, knocking indicates bad bearings on the crankshaft. You are going to have to budget for a rebuild on the bottom end of the engine. If the engine has extreme mileage, you would be better off with a remanufactured engine. your best bet is to get a used motor or if you have the money then buy a new one but either way they are kind of spendy. the cheapest motor i have found was used and priced at $500
A saggar maker's bottom knocker is a young boy employed to make the base of a saggar from a lump of fireclay, by knocking it into a metal ring with a wooden mallet.
To determine if the bottom end of an Audi engine has failed, listen for knocking or tapping noises from the engine, especially during acceleration. Check for excessive oil consumption or leaks, which can indicate worn bearings. Additionally, perform an oil pressure test; low pressure can signify bearing wear or damage. Finally, inspect for metal shavings in the oil, as this can indicate significant internal damage.
Depends on where the noise is originating from, a suspension component, engine (top or bottom?), steering knocking when turning, going over bumps, etc. You need to provide more details before I can point you in the right direction.
Not sure what your asking exactly. But I will tell you this about knocking in Montanas. I have seen a few of them that will start sucking oil into the combustion chamber through a leaking intake manifold gasket. The motor goes dry enough to cause a knocking on the lower end of the engine. End of motor! Check your oil!!!
