Question Answered: 

If the windshield is clean and the blades are new they should not be noisy. The angle of the blade against the glass can be checked and adjusted with a special tool. Sometimes this can cause noise or chatter. A common cause is the wiper motor itself. The lubricant at the worm gear within the assembly dries up leading to wear/noise. The motor element of the assembly can also becoming noisy. The noise is very loud and very mechanical in tone. If this is your noise it would be evident with the wiper arms removed and the wiper motor running. In either case a new wiper motor is called for as the wipers could fail unexpectedly if this is not attended to. If you do determine the wiper motor is your problem be certain the water drains under the battery are clear. Water can get into the wiper motor otherwise.......

Question Answered: 

The computer is plug and play on this model. If the same fault code recurs it is very unlikely it is the computer. Be certain you understand the fault description and the conditions that cause it to be set. Thoughtful diagnosis and testing before replacing parts is the most economical path. Actually if you could tell us the exact code we could offer more help.

A simple test would involve disconnecting the fan switch while the fan is on. If the fan then stops the switch has failed. If the fan continues to run remove the relay , if the fan then stops the relay has failed. Various inputs/outputs at the relay should be confirmed to be 100% certain something strange isn't going on. Above all be careful of the fan itself , if it's running obviously but if it's not it could start during repair or at any time!

Question Answered: 

Hello , You need to do several things first.Using an appropriate scan tool review the freeze frame data to narrow down the cause for the check engine light being on. The codes P1156 and P1161 relate to the MAP sensor and Intake Air Temperature sensor electrical circuits. These should be checked per the wiring the diagram. The wiring and connectors from the respective sensors to the ECM , the sensors , or possibly the ECM itself are suspect. The P0380 is a common code relating to the Glow Plugs and their wiring. Common issues here are the wiring harness and/or the glow plug relay. In these situations properly diagnosing the problem before making "repairs" will save you time and money.

Question Answered: 

Many Diesel owners resort to electrically powered engine block heaters to prevent this. The Diesel require a minimum cranking speed of 400 rpm to start. At the winter temperature you are seeing it is difficult for an unprotected engine parked outdoors to achieve this. Engine block heaters are available from VW or as a common aftermarket product.

The flashing check engine light indicates an active and severe misfire. Audi advises not to run the vehicle in this state.

Question Answered: 

There is no provision for a dipstick or filler tube. The transmission is filled via a fill/overlow port (17 mm hex plug) accessible under the vehicle towards the rear of the transmission pan. The assumption is once the transmission is properly filled the only reason to add fluid would be due to leakage. In other words the transmission does not consume fluid compared to the engine , which does consume oil and is therefore provided with a dipstick.

Question Answered: 

This could be anything from an electrical fault to a fuel pump issue or a major air leak/loose hose clamp problem. If the check engine light is not on and there are no fault codes stored , a good start would be to confirm fuel pressure at the time the failure occurs. Fuel pressure is one of the few parameters not directly monitored by the on board diagnostics. If I understand your comment "All lights come on but none stay on" correctly , the electrical portion of the ignition switch ( a common trouble spot) could be failing. Short of replacement a simple , but not absolute , test can be wiggling the key with the engine running to duplicate the malfunction. Remember , you need air , fuel and ignition for the engine to run....

As an aside the turbochargers can only be replaced in pairs since they are computer matched. In addition there are several critical components such as oil lines that must be replaced concurrently.
