Question about 2006 Volkswagen New Beetle

1 Answer

The Coolent warning light in blue stays on for a long period after starting and then comes back on again for certain lengths of time during longer journeys. Sometimes it also flashes on and off. We topped up the tank but this has not made any difference.

Sounds as if your thermostat may be stuck in the open position, causing it to run too cool. The car runs optimally at a certain temp if the PCM (computer) sees a temp lower than it should be the light comes on. Or the temp light is just plain faulty (crossed wires,bad ground etc)

SOURCE: blue light stays on in my 2000 beetle sometimes flashes

Not certain, but you may be referring to the blue light that indicates when the water temperature in the cooling system is "cold". It's typically blue when the car first starts, then changes color when the water temperature rises. If the light remains blue the water temperature isn't heating up, and you may want to have the cooling system flushed and checked. Depending upon the cars mileage, it may be time to flush the cooling system anyway.

The thermostat will show what the guage shows. the seal on the coolent bottle can be checked for tightness. so it could be a faulty sensor?

SOURCE: My ABS, brake and oil lights keep coming on at the

Its exactly the abs module! and its keeping the ecu from communicating with the rest of the car, when you remove the module your tac will come back alive and the oil light will turn off. There is way to trick the ecu to thinking the abs module is working but it involves taking out the module, it is fairly simple. My email address is, email me, and I will give you pictures and instructions on what to do. Its really easy, your abs and break light will go off along with the beeping!

SOURCE: Blue coolant light comes back on and flashes? why

The light should be for a low level sensor in your coolant reservoir. Check your coolant level (when vehicle is cold), if fluid level is ok then the sensor is probably the culprit.

Hi Maury, Seems you have a number of different problems at the same time. The grinding sound when pushing the clutch pedal would seem to be the clutch thrust release bearing, which is located inside the bell housing and requires the removal of the gearbox to replace. The warning lights should come on each time the ignition is switched on and then they should extinguish after a few seconds. The illumination of these lights is a fail safe system to show that all warning systems are active. The radio will go off during the period when the starter is engaged as a relay shunts all power to the starter during that procedure. The starter motor uses more power from the battery than any other system. The manufactures have taken this into consideration when designing the circuitry and decided as many others have, to adopt the operation. If when starting from cold this does not happen and the radio plays, it is indicating either excessive drawing of power by the starter and may also be the cause of the grinding noise you experience? Regards John

Ive just bought my audi a4 S.E 1.8 petrol 1998.. with 164k...when i bought it the abs lightt was on and also the brake warning indicator light comes on and stays on flashing,and at the same time the abs...

as the mot only says the "brakes work"to a certain efficiency,(the tester does NOT check the depth/thickness of the pads),chances are your pads/discs are in need of replacement.the pads have sensors in them for wear depth, so when checking the pads,front AND rear the abs sensors can be cleaned,and if done by a seat/skoda/vw/audi dealer they can put it on the diagnostic computer to give you a definative answer (this is cheaper than guessing) I replace the pads myself but get the car "diagnosed"when any red light shows.

MY air baglight is going on in my 2002 taho, the dealer ship claims they can't find anything wrong with it, but it's going on for a reson

{: ) Normally, the airbag light will come on when you start your vehicle, and it will flash for a few seconds. Then the light should go out. This means the system is ready. This is the initial system check.
What is not normal is if it stays on after the system check or when the airbag lights come on while you are driving. That means a trouble was detected by the system and will request the airbag light on.Your airbag system may not function properly during this period.
However, if the conditions that set the fault no longer exist at one point or during a certain period, the system will automatically clear the warning light. This will also mean that your airbag system will work normally as expected.
If the dealer coudn't retrieve a code or unable to duplicate your concern, and find the system to be working as designed, certainly they will have to release your car. If you are the only witness and the problem still persists as you believe, your feedbacks on your next possible visit can be of great help in their diagnosis.
You can note down some other symptoms or instances of what actually transpired before or when the airbag light came on. For example, as when you move or adjust your seat, or when you put something underneath the seats, when you pulled the seatbelt, when you moved the steering wheel and pressed on the horn, or like when your rearview display is not normal, when you open the liftgate or hood, or does it come also with another warning light or message, and anything. The technician can only do shop tests, and he can't drive your car for so many days trying to duplicate the concern. It's always you with your vehicle most of the time, and driving on different road conditions.

Warning light "check ride control"

all warning lights come on during start up. its a test to insure all lights are working. if the light stays on longer than it should you may have a leak in the system somewhere. you can check for leaks with a spray bottle filled with soapy water. on top of the compressor and at the top of the airbags are a common area for leaks.
