VAG17832 P1424: Secondary Air Inj. Sys., Bank1 Leak Detected
Check all hoses from the secondary air pump to your air filter housing if they are locked and in place. If they are somewhat hooked up you will get false air flow data and cause a DTC to appear and probably a CEL will come on in the instrument cluster.

Is the heater nice and hot when the needle shows low temp? If the cooling fans turn on and the heater is hot, that leads me to believe the coolant temperature sensor is bad. You should try replacing that sensor. They are only $6 usd here. As long as your check engine light is not on and your fans are running, this will not hurt your car... but this is something you should fix soon if you can. Make sure the engine is cold when you replace the sensor
It can mean some points which can be faulty. It can mean that the ECU is totally failed or there us a serious electric failure. And thirdly, the most common thing that can happen is the Throttle Position Sensor which is also called TPS is defective, broken or out of range.
Please check the Car and call a technician who has mastery in repair because this code is serious.
Thank you Sir, Have a nice day.
I had a VW rabbit that developed mad electrical problems. It started when one day the headlights remained on and would not shut off. It turned out that a $2.00 gasket for the antenna wire had failed. This allowed road water from the wheel well to leak onto the fuse box. In time the fuse panel corroded and shorted out. I had to replace the fuse box twice and use rubber epoxy to seal the leak. Check all fuses and electrical wiring for signs of shorts or corrosion.
This is a common occurance on vw's, you need to check for vacuum hose leaks, this is the cause.
Volkswagen engines rely heavily on vacuum and if there is one cut hose, or one small leak, your car will run like this.
If you can keep it running with the hood up, start listening for vacuum leaks around your hoses on both sides.
Most vacuum leaks occur near the front of the engine bay.
