Hi!

The car may have a problem in the air mass sensor or else in the turbo. The best thing to do is, in first place, to connect a scan tool and check the memory for errors.

The airbag is a independent system. you should also connect a scan tool.

After that, maybe i can help you more.

open drivers door and look on the side of the dash next to steering wheel

Hello,

Obviously, the clutch cable has cut into two. The clutch cable needs to be replaced. Have the clutch cable replaced and everything is going to be alright.

Good luck.

Hi, had total issues with this too! Your back speakers arent going because they are amped by the factory amp in the boot. You have to provide power to the amp so that it will turn the rear speakers on. This was a white and black striped wire in my car (Audi A3 1997) The rear speakers are blue /green and brown/red (left rear) , and the LH rear is brown/red and (forgotten colour) but the wire on the bottom left under those two brown/red wires on the 20pin harness. If you wire it all up like this then your rears should be going :)

Change your Engine Position Sensor, aka Cam position sensor.

Your A3 should sound a warning beep if you leave your lights on. For this to happen the light switch would be in the side, or dipped position, the key out of the ignition and the drivers door open. If it does not sound the car may not be getting either the door or key signal. To check the key out signal, key the ignition to the on position, turn on the radio (probably only work if a standard radio is still fitted) then key off and remove key, if the radio goes off, its a good sign thats ok. For the door signal make sure opening the drivers door brings on the interior light on, this shows it recognises when its open. Let me know if anymore advise is needed.
As for the mic wiring, as far as I'm aware there were no standard/optional phone kits for this age A3.

Sounds like low automatic transmission fluid. Have you checked the fluid level. Have you noticed it leaving spots where it's parked?
We used to have an Audi A4 wagon and the transmission was always reliable for us. We always kept it well serviced. Audi's (like all high performance cars) need very regular service and attention to be kept going well.

SOUNDS LIKE EITHER THE SPEEDO CABLE IS BAD, OR COULD BE THE SPEED SENSOR!

I would suggest that you scan the computer for fault codes. There are different sensors that control ignition and fuel and any one of these sensors can cause the car to stall and refuse to start. The crankshaft positioning sensor could be the cause if it has failed completely. The check engine light may be burned out , therefore no warning lights.

Check bearing and joint/knuckle on every wheel and even on the drive shafts, if there is lack/knocking, that could cause abs and esp light, because sensor doesnt give right information and ecu only records sensor fault but doesnt say why the infromation is wrong.
They changed the sensor but didnt solve the cause!!!

if you want your engine to continue to work, follow the constructors instructions, they built and tested it to extend the life of your car

Sounds as if the parked sensor is not working and the motor cannot "find" the correct
park position so it keeps running and looking for park.

please explain what a Y reg is please ,anyway i think you will find the fault is connected with drivers side master switch if the contacts go in this switch you will loose all control of the window including the passenger side control as no feed is passed to the other side of the car .

Hello first you will need to visit your dealership for your code is registered to your serial number of your car and no two serial numbers are the same.Usually they charge $15.00 to $50.00 and instruction manual is usually included.

check fuse then theft code

hope this helps the nut is there you just have to look for it

Faulty Brake Lamp Switch.

Fault: Shifter Lock Solenoid under shifter not getting power or bad.

pudiste resolverlo? yo tengo el mismo problema

In the most cases for Audi 2.0 TDI the turbocharger is responsible for engine losing power.
The car goes in "limp home" mode!!!
After scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this: Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECU (engine control unit) go in "limp mode" = engine protection software. As a result the "limp home" mode engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault still remain in ECU memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.
