463A definitely not VAG codes they are from one of the cheap code readers.
Audi A4 Quattro - fault code 463a: engine control unit disabled.
This could be a dirty sensor or bad connection somewhere.
The immobilizer light flashes when you insert the key?
Imobiliser pick up loop in the steering column sounds dodgy, take the cowling off & check its connected ok. Just clipped it back in.

I have a99 Quattro a4 2.8 I just put a motor in it. it has good spark and is getting fuel.very time u try to start it. it floods the cylinder and cranks over hard remove fuel pump fuse turns over fine


Sounds like you have either a shorted fuel pump driver ground or a sticking fuel injector or injectors. Remove the injector electrical plugs and see if it still flood if it does then then one or more injectors are defective, if not then the engine wiring harness is grounded to one or more injectors or the PCM (powertrain control module) is defective. Remove the spark plugs to ID which cylinder is defective, disable the ignition system when you do this or the gas squirting out the spark plug hole can ignite (been there)

1998 audi a6 2.8 quattro tiptronic doesnt work but auto still fine?


Google it - Check this LINK. If your horn or other steering wheel controls do not work, it's likely the clockspring - the device that transmits the inputs from the steering wheel into the wiring harness under the dash. Pray it's not, otherwise your Audi tech will be buying himself a new S4.

first relief fuel pressure before disconnecting fuel lines remove fuel pump fuse or relay start engine let it idle until stall out lack fuel fuel now fuel pressure is reliefed. you have to remove top upper air cleaner housing, you have to remove whole entire air cleaning system because the fuel lines with fuel injectors is under the air cleaner filament you have to remove entire fuel line with fuel injector in order to replace fuel injector.

Code P0118 on Audi A4 - Related to Ignition Coil Problem?


Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..
