Sometimes you have to slightly overfill the air and then let the pressure go back down to the correct level. If you have direct type sensors, just add air to the recommended tire pressure. How to reset the TPMS system and flashing TPMS light I tried it with a 2006 ABS control module and it didn't work. You must have a compatible ABS control module to make the indirect type system to work. If you have the direct system and have a compatible ABS control module, it might be possible to switch the indirect system for a second set of wheels or permanently switch to the indirect type system if you don't want to replace the sensors after their batteries die. See the TOS Agreement for the full legal disclaimer. In the US, a functional TPMS warning light is required under Federal requirement FMVSS 138. Warning: Never disable the TPMS light, disable the system, or disable the TPMS light if it's not legal where you live and/or operate the vehicle. A valve stem is the piece of tire that sticks out and where you add air. If the valve stems are flexible rubber you don't have these sensors. If the tire valve stem is metal and stiff with the lock nut on the base, you have a direct sensor system. While it's legal to have a TPMS which no longer detects tire pressure (except on a new car sale), it's not legal to disable the system or disable the light.Ī direct type sensor sits inside the wheel with only the antenna/valve stem sticking out. The battery life of TPMS sensors is about 6-9 years depending on use and it's non serviceable. The advantage of the indirect system is that it doesn't require a second set of sensors for winter wheels (unless you want to unmount the tires to remove the sensors) and because there are no sensors they don't need replacement when their battery dies. The advantage of the direct sensors is that it's more accurate. More expensive models like the Touareg still use direct sensors. VW switched to the direct system but has switched back to the indirect system for model year 2011 in Golf and Jetta. Because it's not yet mandatory in Canada, many new Canadian VW don't have the TPMS. The indirect system was installed starting in 2007 when it became mandatory in the US. The other type uses wireless sensors to directly measure air and temperature in the wheels and transmits the data to the car's computer. If the wheel sensors detect that one wheel's diameter is smaller it assumes that the tire has lost air and trips the low pressure warning. The first type works off the ABS system and uses no additional sensors. There are two basic types of tire pressure monitor systems installed in VW. This article shows how to reset or activate the hidden ABS based TPMS or swap from the direct to the indirect system Some recent VW Golf and Jetta have the TPMS capability without having the button. How to activate, reset, or swap the TPMS system on your VW Jetta or Golf
