Reset after changing battery
2012 VW Passat mu car won't start after replacing
the battery to I have to reset the computer? If so
I don't know anything about VW's but changing the battery should not require a "reset". Try double checking your work - Pos & neg cables hooked up to the right terminals? Wiring connections clean and tight? Battery fully charged? Do your lights illuminate when you turn them on?
VW immobilizer kicked in. Preventing a start up. check your manual or check back later if you need the procedure.
the biggest mistake people do with late modal cars is think they can remove the battery with out a back flow of current to keep the computer from wiping it self. when you go to replace or remove a battery you need to attach a tender to the cables to keep the voltage in the car going or else the car forgets all its settings. if you have a blue key symbol on the dash the immobilizer is on and won't allow the car to run. This often results in needing to reprogram your key to your car. ou can try this tho.. put the key to Power ON only and wiat 15minutes. after the time is up turn to power off then try starting the car. this might or might not work.
Help ME.. My battery died and I changed it. Now da Danggg horn won't shut off.. it's driving me crazy#What do I Do???? Please helo
disconnect the battery and then find the horn trace the wires till you figure out where the wires are crossed. you likely have a short some where (most shorting issues are at where the wireing cables go threw the fire wall.
