Re: 2001 volkswagon beetle check engn light came on
The pumps play up ,can you hear it running when you start the car from cold?if you carnt check the power supply at the pump connector with a multimeter if you have power there you have a pump problem,if you havent got power you have electrical fault

VW Emissions Code P0411. .... VW 1.8T Secondary Air Injection Pump Replacement for Fault Code P0411 - Duration: 8:48. by Deutsche Auto ...
secondary air injection incorrect flow with out being able to hook up a scanner and see live engine data the most common cause that i have seen is a bad solenoid sensor and a bad check valve in the secondary air pump
p0411 code is Secondary Air Injection System Incorrect Flow Detected. Google it, there are tons of VW forums out there. I would check your air pump, check all of your air hoses to be sure they aren't cracked or torn, try cleaning the mass air flow sensor, check your purge valve I had a friend that got that code and it ended up being her purge valve. Also try checking the vacuum hose to your EGR valve. Make sure to unhook the battery to reset the computer. Hopefully one of the above will work for you.
P0411 Secondary Air Injection System Incorrect Flow Detected p0411 is a generic code, probably a vacume leak,vacume hose broken check this first, check the air pump turn on the car but it needs to be cold, you should hear a high pitched whine, this is the air pump running,there are 2 hoses one suction one blowing thishose should be going from the air pump to the air cleaner disconnect that and see what the volume is should be pretty strong. But mostly you probably have a broken vacume line somewhere
P0411 Secondary Air Injection System Incorrect Flow Detected
The 4mm inside diameter vaccuum hose gets pinched between the lower intake manifold and the secondary air pump housing, flattening it over time.

P1128 Long Term Fuel Trim Is Too Lean
It is very likely this code is coming up because of the vacuum hose as well.
If were to venture a guess(and i am) it is either a valve or something that regulates either the rate of fresh air or the direction of it. Check the sec air valve or whatever VW calls it for blockage or sticking.
The P0410 code refers to the emissions system. The AIR pump puts air to the
exhaust to lower emissions. It takes in outside air and pumps it through two
one-way check valves into each bank of the exhaust.
About 90% of the time that this code is set, the one-way check valves have
worn out or failed and allow water (which occurs naturally in the exhaust) back
into the pump. In any cold climate, especially in climates with higher humidity,
this water may be more excessive. The water partially fills the AIR pump, it
can then freeze. When the PCM commands the pump on, if the pump is frozen it
cannot turn, thus overloading the circuit and "popping" the fuse.
