What is the code P0442 on a 2013 VW Tiguan?
Possible Causes of P0442 A loose or incorrectly affixed gas cap. A gas cap that does not meet vehicle manufacturer standards. A tiny crack or hole in a fuel vapor hose or tube. A different type of leak somewhere else in the EVAP system. Below are the most common causes of engine code P0442: A loose gas cap that doesn’t provide a tight seal. Splits, cracks, or other damage to EVAP System hoses or fittings. Faulty purge or vent valve.A P0441 trouble code is triggered when the ECU detects a malfunction within the EVAP, indicating the purge valve is not regulating the fuel vapours correctly, allowing too much or too little flow. The purpose of the EVAP system is to prevent fuel vapours from escaping into the atmosphere.Common causes of the P0442 code include a malfunctioning fuel cap, a leak or damage in the EVAP system line, charcoal canister, or fuel tank, a malfunctioning vent valve or purge valve, a faulty FTP sensor, or a failed leak detection pump.The P0441 code can also indicate a faulty or stuck PCV, a short circuit in the feed circuit, or a faulty purge solenoid.Most of the time, removing and putting the gas cap back on and then clearing the code will solve your vehicle’s P0442 issue. If that doesn’t work, you may need to replace your gas cap with an OEM gas cap (assuming you’ve got a generic cap installed now).
What is Volkswagen code P0441?
A P0441 trouble code is triggered when the ECU detects a malfunction within the EVAP, indicating the purge valve is not regulating the fuel vapours correctly, allowing too much or too little flow. The purpose of the EVAP system is to prevent fuel vapours from escaping into the atmosphere. Diagnosis of the P0441 code can be done both without a scan tool and with a scan tool. Without a scan tool, a visual inspection of the EVAP system should be conducted, checking for obvious problems such as a loose gas cap or damaged charcoal canister. If no issues are found, the purge valve needs to be tested.The simplest solution is to remove and reattach the gas cap. Once you do, clear the code on the OBD-II scanner and drive for a few days. If the code does not return, your gas cap probably was the culprit. Of course, there is a chance your gas cap either has worn out or is not compatible with your EVAP system.
Can you drive with a P0441 code?

In the short term, your car may operate normally, but the unresolved problem could lead to a decrease in fuel efficiency and an increase in exhaust emissions. The P0441 code can also indicate a faulty or stuck PCV, a short circuit in the feed circuit, or a faulty purge solenoid.

Yes, you can still drive with a P0441 code, but it may cause the check engine light to turn on. While an incorrect purge flow won’t damage your car, ignoring it can lead to other issues. For example, a persistent check engine light may mask a new, more severe engine problem.
