This light means Electronic Power Control - The onboard computer has detected an issue with one of your electrical systems.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially go on

most likely the wiper signal arm itself if you have tilt wheel over time the wires stretch wear and break causing a short otherwise have a test light handy and with the wipers on position check for power at the wiper ,motor if none is present its the switch if it is present its the motor

sounds like it could be a bad ignition switch

There is a flap in the boot that you need to flip open. Once opened, there are two screws with really big round ends as big as 1.5 - 2 centimeters in diameter. One is black on the lower end of the light and the other is white which is on the upper end of the lamp. You may need a tourch to see them better, however you can not miss them. Unscrew them with your fingers by twisting these anti clockwise. You need to hold the lamp as as soon as these 2 screws are released, the lamp will then be held by a wire connector which you can remove. You then need a star head screw driver to open 2 screws which will allow you to remove the bulbs that are deffective and have them replaced. Then just retrace your steps.

look fo an accident damaged vehicle,the turbo alone is a fortune let alone a damaged engine.Unless you can find a old time mechanic that could rebuild you old engine.Another alternative is to use any voltswagon engine of the same type but from a different vehicle because as soon as you say TT up goes the price .Or buy a cheap banger like an old saturn or escort

There is no sensor for water/antifreeze mix. If its on your probably having some other issuse (your local auto parts store can scan the codes for free and tell you what the light is on for). But to answer your question the proper mix is 50/50. You can purchase the antifreeze already pre mixed so you only have to add it. If you have too much antifreeze the car will tend to overheat in the summer and if too much water the engine could freeze in the winter time. The mix is critical to your cars performance and reliability

If the pedal keeps dropping the master cylinder is probably going bad (most common). Another tip is the rear brake pads hold the pedal height. Check your rear pads to see if they are low or need replacing. Most brake shops do a free inspection so I would let them do the leg work for you. Go to a reputable shop or if unsure get multiple estimates before performing the work

yes the pins do tend to wear on these replacing them should quiet that noise.

On the TT The mass air flow meter can cause lots of problems when trying to read codes.I would change that and that should solve your problem.Hope that was helpfull.

you should have the switch checked out/changed...probably an electrical fault.

hiya,i dnt know about the shuddering/turbulance,but a can of Aircon Cleaner and Purifier will definately helps the aircon system and the mouldy residue. Hope it solves part of your problem.

Should've went with new one with a warranty. Used engines and transmissions are just that. You don't know what kind of abuse it has had, if anyone did the maintenance on, or anything else. Was there any kind of warranty from the salvage company? They do usaully give at least a 6-12 month warranty on something like that.

How long does it run with key off ?

Could be timing..

Hope this helps !!
Please rate me good ;o)

When your ABS light comes on it means you have no ABS only normal braking. Also a traction light will come on at the same time becaust it is directly linked to the ABS to change torque before a wheel slips. You need to have it hooked up to a professional scanner, because there are many different possibilities of what is wrong with the ABS/TCS system. hope this helps!!!

This will have to be serviced by qualified technician. Either the control circuit or pump is bad in the unit.

In most cases, that just means you gas cap is loose, screwed wrong, or defective. First off, try to unscrew it completely and screw it back on carefully, but make sure it makes a few clicks once it reaches the end of the thread, or else it might not be on tight enough to seal the ventilation system for the computer's self checks. If you did all that and it still gives you the same problem, then change the cap completly with a new one. You can buy one directly from Audi, or you can buy a jobber model from a parts store, or you can always scrounge around the scrap yards and try to find one too, but be aware that not all gas caps are the same, so you really need the specific one for your audi if you don't want more problems. If a new gas cap does not solve the problem, then you will need to raise the car and take the fuel tank down to inspect each and every fuel hose for cracks or leaks.
