Jetta dashboard light--looks like water temp.

Check brake light switch. Check ECM for faults.

No, this is a warning signal that notifies you that the gearbox is defective, has been put in Limp Mode (an emergency mode designed to keep the gearbox running at all costs as to allow you to reach home) and it will have to be serviced immediately. It will be very expensive.

Have you checked the coolant level in the overflow tank? Make sure it's to the proper level. The coolant warning system can lose its little brain on the VW's. Sorry I can't be more helpful.

i believe this is either a low tire pressure light, or low brake pad light.

Hi, i'm pretty sure that it's the warning light to tell you to drain the water trap on the bottom of the diesel filter.
Hope that helps Matt...

it means you are low on coolant

check the fuse and make sure the dimmer isnt turned right down.

this says that one of your bulbs is not operating. check all lights round the car, including the brake lights (have somone to oberatge the brake while you have a look). you will see one not working. replace and sign goes away

my 95 vw jetta oil light is on and there is a beeping sound what might be wrong
