Start by draining some of the oil out. I f you don't pan gasket or main bearing seals may start leaking due to high oil level.
from cliff:
According to something recent, I think at the VW dealer, overfilling can damage the catalitic converter. According to my old-school-Dad, excess oil would be blown out the "breather tube"; better a quart low than a quart high (he would tell me.) Those were the days before the California Cat Converters existed, yet I know not if such a tube still exists, where it discharges, or why they would permit the expensive cat converter to be damaged by overfilling.
Tangent; leaky fuel injector, and other things, can cause gas (or antifreeze) into the oil supply, raising the level while also reducing lubication due to thinned out oil.
You can't - it's controlled by the engine management system.
it is on because the ECU has detected a problem with the emissions system.
Nothing will happen if you drain the cooling system and replace the coolant.
Overfilling a power steering system with fluid can cause overpressure. You may cause a leak in your lines or pump.
If my engine is hot, I would not even notice that as it evaporates very quickly...in hot oil.
You can't it is a closed system and it needs to be done by a professional.
Usually a problem in the emission control system - have vehicle scanned to determine the problem
Probably not. The larger engine and 12 volt system needed more room. Beginning about 1967 the rear deck lid had a camels hump.
As much as it takes to top the system off. Do not overfill!!!!!!!!!!!!!!
You will screw your steering system. You need to flush steering system ASAP. And of course do not drive with engine oil in steering.
No
When your code reader says this you probably need to go into a shop and either find out what you need to pay to have the beetles coolent system flushed and or replaced
