Wont power from my audi a4 even with original iso blocks

Question edited for clarity.
Question mover from 'Power computers to model category.

It has some strange 'Connector Stations', but check the connection pins under those fuses. To find a full wiring diagram, you need the service manual or a subscription to a site like AllData.

have u replaced the spark plugs and wires?

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.

well i dont know how handy you are but check if the grounds are all good also check if you are getting power to the stereo sum have a fuse in the unit

This is normally one of 3 problems:

1 - Refriant too low
2 - Pressure sensor faulty
3 - Climate Control Unit faulty

In order of cost -

1 - Re gas approx 49 pounds
2 - New sensor - 50 Pounds
3 - New climate control unit circa 700 pound

I have just had the same issue and after a re gas and new sensor it all works okay.

remove the fuel pump from the tank and check the electrical block connector and the wires underneath the unit that runs to the pump

Silly question: Have you checked the transmission fluid level, and is it to manufacturer's spec?

you need to replace the unit

Most likely the sending unit for the guage is defective, it is located in the fuel tank.

P0130 is 02 sensor bank 1 and P0150 is 02 sensor bank 2.
