Warning light stays on the dashboard. don't know

Potential foundations for light issues in 2012 VW Jetta TDI: really look at wires, assess bulbs, wiring issues, flawed light/dimmer switches, control module, or battery. Counsel a repairman for precise finding and fixes.

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.

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...

the 'comb' is a thermometer,it's the 'hot'light,indicating high temperature of coolant.check coolant level,check for leaks.

it means you are low on coolant

Should be a Bulb Out Indicator. Check all your external lights (headlights, brake lights, turn signals) and make sure they are all working correctly.

You are low on coolant

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

I have the same car,It could mean that there is a light bulb out

My '01 TDI had the same issue and apparently it was a switch gone bad behind the horn and airbag. . . so no idea if the airbag would have worked had I been in an accident. Definately worth going to VW and having it looked at though. Better safe than sorry.
