2009 gti needs a software update for a Tsb. The t.p.m.s. light is on I would like to turn off system or just the light. I have a vagcom! How do I do these things?
Technically some form of TPMS is required on all cars <8700gvw manufactured as of September 2007 for the US market. But unlike emission laws, the legalities after it leaves the dealer lot are a bit fuzzy.
AFAIK, It is illegal for a shop to disable the system, but it is perfectly legal for a shop to install aftermarket wheels, remove sensors, etc, as long as they leave the light blazing on the dash. It is also not illegal for a backyard DIY-er to disable the system on their own vehicle.
I thought VW went back to indirect (wheel-speed sensor) TPMS last year? If so, any matching set of tires should not illuminate the warning provided equal pressure. Uneven tires (for example one new tire and 3 worn tires) might turn the light on though.
I also recall a method for recoding older models from direct (in-tire sensor) TPMS to indirect TPMS, which would be perfectly legal. We would need a scan to offer any help to the OP though.
