Reset the tire pressure warning, same as you would any service issue. Insert key in ignition, hold wrench button and min button, then start engine.

SOURCE: I have a 97 volkswagen Jetta GLX that is idleing very low

there is no code......unless you're using a vag-com?
have you disconnected the battery recently? or anything of the sort. if so, you may need to align your throttle body. anyhow, disconnect the battery for 10 minutes or more. it takes at least 10 minutes for the ecu to reset, so the longer the better. now, reconnect the battery, as quickly as possible, get in and turn the key to the battery. youll hear a buzzing of sorts from the engine bay if its working. leave the key on battery for 3 minutes. the buzzing will have stopped, before 3 minutes, but after the 3 minutes, start the car. now, let it sit at idle for 3 minutes, dont touch the gas. just let it sit. after 3 minutes at idle, go for a drive and you should be all set. hope that helps.

SOURCE: My 1996 jetta horn does not work. Fuse / relay okay

hi did you also checked the horn itselfs. when you take out the horn and look at the back you will see a adjust srew with sealingmastic on it. you can remove the sealingstuff and try to adjust the horn. this only works if the coil is not broken. but first you have to check the connection inside the steeringwheel. make sure the switch in the steeringwheel is making contact to earth. if this all doesnt work you have to buy a new one goodluck.

SOURCE: the horn on my volkswagen jetta 1999 will not work

check all your fuses first. if they are all good, remove the horn relay and check to see if it has power to it with key on, horn not pressed. it should. if it does, check to make sure the power is flowing through the relay when horn is depressed. theres should be a wiring diagram on the relay. if power is not getting through, replace the relay, if it is getting through you have a broken wire between relay and horn.

Horns relay output is correct, but only 8.1 volts reach the horns, they work but not as they should.

Have you tried a heavier gauge jumper wire from relay to horn to see if it makes difference? Plus clean ground on horn?

Hi. When I turn my car on the horn is sticking and won't stop. But I can still push the horn and it sounds. I have a 2006 VW Passat 2.0t

I'm not sure I understand this. If the horn is already honking, how can you honk it? Most cars have two horns. A hi and a low sound. While the horn is stuck, open the hood and disconnect the one that is sounding. That won't fix the cause, but at least it will be quieter until you can have it diagnosed by a mechanic.
