Product Information

MC68HC908AZ60 2J74Y processor already programmed with software 509019 303412 A4 diesel V7.82ML for repair A4 1999-2001 dashboard made by Magnetti Marelli. Defective instrument cluster symptoms – dashboard not switch ON at all, some displays are black, all lamps blinking, sometimes all pointers go back to “0” positions and dashboard restart’s itself.

Some repair helps:

About your problem with fuel gauge:

1) first you must do instrument cluster test with VCDS: https://www.youtube.com/watch?v=zvb70NPIhtc

Also more information here: http://www.ross-tech.com/vag-com/cars/audiB5.html

This test can help you to set pointers on motor in correct position: after test fuel and temperature gauge pointers stop in the middle of scale.

If pointers positions is not correct – adjust it.

2) if after IGNITION ON/OFF fuel or temp pointers changing positions – this is not processor problem! Please find bad soldered contacts on PCB or exchange pointers motor: https://codecard.eu/electronics/others/audi-tt-temperature-and-fuel-pointer-motor-for-magneti-marelli-dash/prod_393.html

3) If everything is OK, just fuel gauge works in reverse – incorrect part (cluster) is installed in car. In Audi can be used 2 kind of fuel level meters – normal and reverse. Then fuel is empty one dash can show “0”, other “full”.

This fault usually appears when you swapping instrument clusters. Is not possible to adapt fuel gauge type by ODB2, you must exchange instrument cluster.

We can reprogram this function by full dash software programming (we need to reprogram both processors (small HC08 and big HC12) and after make instrument cluster immobilizer adaptation.

Check if the original 2J74Y processor software are the same – this is very important. Just exchange already programmed 68HC908AZ60 2J74Y processor in cluster. Our preprogrammed processors no need additional OBDII adaptation.
