Look in the owner's packet in the glovebox. There's a second book specifically for the stereo system. There should be a detachable card in there with a four-digit number on it. That's the radio code. The stereo manual explains how to enter it to unlock the radio. If you don't have that code, you'll need to take the car to the dealership. With proof of ownership of the vehicle, they can look up the code and enter it for you (make sure they write it down for you for future use, and show you how to enter it, since they're going to charge you an hour's labor or so to do this).

It needs a U-key. You can make one by yourself by cutting a wire hanger into 2 pieces about 6 inches long and bending them. Insert the into the holes on the sides of the radio and pushing. It will pop out enough for you to pull it out.

If the vehicle shakes all the time when driving, it is possible a coil pack fault, and yes it is common, if it shakes when you get toa certain MPH, its possible tyre fault or wheel balancing

Replacing timing belts is not for the faint of heart and for amateurs. Small mistakes can create severe engine problems. This is best left to a pro.

PO432= 1 OF THE SENSOR IN THE EXHAUST SYSTEM if u stand in front of engine to your rt under the car should be a oxygen sensor just unplug it and put a new one.....(bank2)
PO441 = Evaporative Purge Flow Monitor check your fuel cap and replace all of your vacuum hoses because they can be damaged or plugged this should fix it.
So good luck to ya....

When that light flashes that is a signal to get the car into a repair shop immediately. The flashing means the catalic converter is in jeopardy of being damaged probably by unburned fuel entering it and being burned in it, making it operate much hotter than normal. Get it to a shop !!

It is very possible that the abs pump is faulty. As a mechanic myself, I recommend taking it to a dealer.

you may have a faulty tcm (transmission control module)

is the hi-fi system fader set to much too front? usually the simple things are the best to check first.

is the pump all the way sealed. and hooked back up. is the fuel level sensor in the correct position. if all that is good a good way to check and see if it is the pump itself have someone try and start the car while you pound and i do mean pound with fist NOT hammer on top of the seat just above the the pump see if car starts you also could have popped the fuse for the pump. that fuse is in the fuse panel on the left side in drivers door panel fuse is on the bottom left two or three up from bottom row. closest to the pillar. good luck.

What I would suggest is taking the car to an autoparts store and have them scan the computer for any fault codes that it has stored. Most parts stores will do the scan for free. That should eliminate the need for speculation. It could be an emission related problem or it could be something totally unrelated. Better to get the codes to narrow down what the computer has noted. Hope this helped and best wishes.

They could be related. Most likely your air injection is dumping at the wrong time. You really need to get this diagnosed by a professional. Hands on is the only way to do this.

not sure but i think their may be a big 80amp fuse near the battery ,look for dodgy dirty contacts on the fuse ,i think their may be about 4 of them ,windows ,ignition,rad fans,and altenator,,, but i cant remember where they are only that they are near the batttery

have you checked the bulbs the parking and brake circuits are seperate from each other

hi it probly low on feron

If you no longer have your manuel, you can go to the dealer and have them enter your code if you have it. If you don't have the code for your radio or you just need the instructions, go to www.rado-code.com. They should get your radio working again for a small fee, much less then any dealer would charge. Good luck and keep me posted, would like to know your radio is working again. Be glad to help. 

this is a security feature that Audi does on their OEM stereos. you have to go to the dealer and ask them to get you the security code to unlock it. check if you still have your original factory manual, as it should be listed in there.
