WHAT DO U MEAN FLASHES!!IT IS NOT SUPPOSED TO FLASH.IT GOES ON AT IGNITION ON AND OFF WHEN CAR STARTS.NEED MORE INFO

I have the same problem. What was your solution?

Does the moisture smell link coolant? Use a white napkin and wipe the inner windshield, Compare the color to your coolant tank. This will verify is this a heater core problem =========== Next item that can trap water is the A/C drainage problem. You will need gloves for this. Most A/C drain is ion the bottom of the center console. The bottom of the tray is a A/C drain tube and pan. Check for drain blockage. (DIRTY JOB!)

Brake booster pump has stopped working, replace.

Hi there:You will need to have diagnostic codes checked which can be done for free at parts store.We have seen where the vehicle will run rough and have poor throttle response because the wiring right at the throttle body is bad because the wire terminals are loose right at the connector the first thing you will need to do is check the wiring and check the trouble codes stored in the engine control module to see if you have trouble body codes this needs to be the next step .EPC stands for Electronic Power Control. This is the drive by wire throttle system used in Audi and VW gasoline models. Here is a list of some of the related components:- Throttle Position (TP) Sensor G79 - Sender 2 for Accelerator Pedal Position G185 - Throttle Valve Control Module J338 - Angle Sensor 1 for Throttle Drive G187 - Angle Sensor 2 for Throttle Drive G188 - Brake Light Switch F - Mass Air Flow (MAF) Sensor G70Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

the fact you have high beam and not dipped beam .means it is your switch has failed.

Not sure that the O2 sensor was bad. It sounds like it was telling you that side of the exhaust system was picking up a lean mixure at the O2 sensor. The O2 sensor was doing its job by telling you the mixture changed. If the O2 sensor was bad, it would say low voltage range for that sensor, or open curcuit.
Now the car has had time to do its diagnostic sweep, it is telling you the same thing, but from a different sensor...the fuel mix is too lean. Air/spark/and fuel is what you need in the correct amounts. In your car, the ECM engine control module controls this by taking readings from all the sensors several hundred times a second.
Mechanically, you have a few options. Change the fuel filter...under the car on the passenger side. It is an easy job.
Change the fuel pressure regulator. This keeps the fuel at 4 BAR so the fuel injectors can do their job correctly. This job just needs a screw driver to pop off the clip that holds it in place. No hoses need to be removed. It is on top of the intake manifold, in-line with a metal fuel line and a rubber one.
The fuel injectors could be clogged up on one side of the engine. Run some fuel injector cleaner through a tank of gas. Also, listen for a constant ticking sound at each injector. If one sounds off PAR, then replace it.
The fuel pump may not be giving you enough power. However, the readings seem to be localized to one side, so I doubt it.
Start with the easiest thing, and see if it works. Also, you will need to get yourself a VAG scan tool. It is the only one with codes in it for all of your VW systems, not just engine codes like the ODB scanners. You can get a nice one for $50 on-line.
Good Luck!

It's behind the center of the dashboard. You will need to remove the dash board to access the core. Just follow where the coolant hoses go through the firewall, that eill tell you where it is. Sorry no shortcut for the dash removal, only way to remove it is removing the dash.
