I am by no means a car expert. My experience is based only on past experience not just with my 2003 audi tt but other cars as well.

What you describe may be your transmission slipping. You should have it checked out asap before you need to have the flywheel cut--I had that happen on another car and it was very expensive to have repaired.

My tt also has some brake problems which cause it to stutter when I get close to a full stop.

The best of all though is the recall of our cars for replacment of the timing belt--according to my dealer a $1700 job.

SOURCE: location of fuel filter on a 2001 audi tt quattro

On a 2001 Audi TT Quattro the fuel filter is located forward of the fuel tank, in the right rear wheel well area. The fuel line clamps are a bit tricky. The change will improve performance. The owners manual does not even list changing the filter. But do it! use a Fram, and it fit perfectly. Good luck.

SOURCE: 2005 Audi A4 1.8 Fuel Pump problem?

I had an Audi A4, 10 years older than yours mind you, but it would start then stop, sometimes 10 times but would eventually go. I ran a little WD40 in the key barrel and put the key in and out a couple of dozen times. Wiping it with a cloth each time, lots of dirt came off. My theory and it's only mine, is that the wear on the key left dirty metal deposits inside which stopped the chip in the key being recognised. I believe they had a security chip inside the key.
Anyway after 6 months of this nuisance it never happened again after that. Fixed my problem and a lot of frustration. Maybe help you too.

Where is the fuel pump relay and how can e serviced?


Description

*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine start ability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.

Hi there:

DTC P0032 - Oxygen (A/F) Sensor Heater Control Circuit High (Bank 1 Sensor 1)
A P0032 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 1 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2.

This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. The sensor detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle's computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the O2 sensor. Essentially this P0032 code means that the resistance of the heater circuit is higher than normal. In some cases, that resistance level must be higher than 10 A to trigger the DTC code.

Note, this code is very similar in nature to P0031, P0051, and P0052

Most likely you'll not notice any symptoms other than the MIL (malfunction indicator lamp, a.k.a. the check engine light) will illuminate.

A P0032 DTC trouble code may be caused by one or more of the following:
A short in the heater circuit in the sensor
A failed O2 sensor heater
Wiring/connectors broken/frayed leading to sensor and/or relay
Failed PCM/ECM

Possible Solutions:
To fix a P0032 DTC code, you'll need to do a proper diagnosis. To do that, you'll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you'll want to check those as well. Use a digital volt ohm meter to:

check for 12 volts at the heater circuit feed (hint: unplug the sensor and check at the wiring connector to do this measurement)
check the ground circuit for continuity
measure the resistance of the heater circuit (done on the sensor itself)
measure the resistance and voltage of the wiring

Refer to a service manual for the correct specifications (volts, ohms) for your vehicle. On some Toyota vehicles this code is triggered when the resistance of the heater circuit is above 10 A.

With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #2 on bank 1.

Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer). Aftermarket sensors can be less reliable and of poorer quality (not always, but more often). There's also a chance that replacement parts for the P0032 code may also fall under a federal emissions warranty (check with your dealer to see if it's covered).


DTC P0463 - Fuel Level Sensor Circuit High Input
The fuel level sensor (sender) is located in the fuel tank usually integral to the fuel pump module. Usually they cannot be replaced without replacing the fuel pump module, though there are exceptions. There is a float attached to an arm that travels along a resistor which is grounded to the tank, frame or has a dedicated ground circuit. Voltage is supplied to the sender and the ground path changes according to fuel level. How much voltage depends on the system but 5 volts isn't uncommon.

As the fuel level changes, the float moves the arm and changes the resistance to ground which varies the voltage signal. This signal may travel to a fuel pump computer module or directly to the instrument cluster module. Depending on the system, the fuel pump computer module may only monitor the resistance to ground and then relay the fuel level information to the instrument panel. If the fuel level signal to the fuel pump module (or instrument cluster module or PCM (powertrain control module)) goes above 5 volts for a specific amount of time, then the module that is monitoring the fuel level circuit will record this fault code.


Symptoms of a P0463 DTC may include:
Mil (Malfunction indicator lamp) illumination
Fuel level gauge may fluctuate abnormally or read empty or full
Fuel light may illuminate and sound alarm


Potential causes of a P0463 code include:
The signal circuit to the fuel sender is open or shorted to B+ (Battery voltage)
The ground circuit is open, or ground path may have high resistance due to rust or missing ground ******** fuel tank
Damage to the fuel tank could cause problem in fuel level circuit
There's an open in the fuel lever sensor's resistor to ground
Possibly faulty instrument cluster
Less likely is the possibility that the PCM, BCM, or Fuel pump computer module has failed


Possible Solutions: Fuel pump senders normally last the life of the fuel pump. So if you have this code present, do a visual inspection of the fuel tank and wiring harness. Look for damage to the tank indicating impact that may have damaged the fuel pump or sender. Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector. Repair as needed. Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness. If not, repair the open or short in the wiring.

Doing a voltage drop test on the ground circuit can determine if there is a high resistance path in the ground circuit. You can perform this by using a voltmeter and connecting one lead to the battery ground post and the other to the fuel level sensor ground at the tank. Turn the key on (preferably the engine should be running). Ideally it should be 100 millivolts or less (.1 volts). Anything close to 1 volt indicates a current problem or a developing problem. Repair/clean the fuel level sensor ground as needed. It's not impossible that the instrument cluster has failed internally or on the printed circuit board (if applicable). These are very difficult for the layman to test. But if you have access to a wiring diagram you may be able to remove the cluster and see the damaged circuit if it's located on the printed circuit board, but otherwise you'll need a scan tool that will communicate with the instrument cluster.

A simple way to test the fuel level circuit is to provide a good ground to the fuel level sensor at the fuel tank connector. With the key on the fuel gauge should go to one extreme or the other. Removing the ground path completely should cause the gauge to do the opposite. If the gauge responds, you know the wiring that supplies voltage and ground to the fuel level sensor is good and that the instrument cluster is likely okay. The likely suspect would be the fuel level sensor itself. The fuel tank may need removal to gain access to the fuel pump module in the tank. A PCM or BCM (Body control module) failure isn't impossible but highly unlikely. Don't suspect this first.

Also, DTC P0462 - Fuel Level Sensor Circuit Low Input, same test to diagnosys.

DTC P0700 are transmission codes. Apparently something went wrong and the computer detected a difference in the position of the shift linkage and what gear the vehicle was in. You should be able to drive the vehicle during this period of time. The only thing you should be aware of is to make sure you don't feel any transmission slipage, otherwise you are fine until your appointment.

DTC P02610 - Control Module Long Term Memory Performance
This code is often set because the battery went dead and you tried to start it. There is a calibration update to correct this and it will not require a new ECM. See you dealer for the calibration update.

- Fuel level sensor may be faulty

Possible solution
Replaced fuel level sensor.

Hope helps (remember to rate this answer).
