2005 Audi A3 - Page 4 - Answered Questions & Fixed issues

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.

The electronic throttle acuator is part of the throttle body. Just follow the air inlet tube from the air filter box to the throttle body where the throttle pedal cable attaches.

its mean that your car reguler service is down

It's most likely the turbocharger. We used to have an Audi with a turbo and it had a bit of a whine when accellerating. A slight siren type of noise is normal for it, but, if it's real loud then it should be checked.

Lift your hood you should have 2 dipsticks under the hood. The closest one to your fire wall should be your transmission dipstick. The fluid should be red in color. You want to have the engine at operating temp and also running while you check it You will want to have your transmission in park or if a manual in neutral.Then when you pull the stick you will see writing on one or both sides of stick you will want to follow the instruction's that are on the stick for measurement.That way you are sure not to overfill it Overfilling may cause damage to your transmission. Always put on your emergency brake while checking your fluid.

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.

Most likely your brake light switch is stuck on you will probably need to get it replaced.

ITS GOT A CHAIN DRIVE......needs changing at 150k with tensioner.

Hard to say what it is without a visual inspection. Take it to the nearest repair shop as soon as possible.
I don't think its a suspension issue cause especially in an A3 you would see it in the curb height and feel it in the ride.

dealer only and expect a bill of anything up to 2500 euros ,dealer only encrypted software job sorry to have to be the one to inform you ,alternative is to connect a heater glow plug relay connected to the light so it goes out for the annual inspection

ask with audi company
