530d Dash console K-bus fault?

[EIG6555]

I have a 2002 530d (E39). The car had an intermitent fault which has now become permanent. I also have a 2000 530d which previously had the same intermitent fault but has now disappeared. I'm baffled...

1. The CD player does not work, but the radio is fine. The digital clock on the radio display is not showing. The audio control function on the LHS of the steering wheel do not respond at all.

2. The air-flow selection switch on the RHS of the steering wheel does not work, but the Cruise-Control functions on the RHS are all fine.

3. The front and rear parking sensors do not respond.

4. The reversing lights do not work.

5. The dash warning lights for Main-Beam, Turn-Signal and Fog-lights do not respond; although the lights externally are actually working.

6. The dash 'graphic' display for doors-open and bulb-failure warning does not show at all.

All six failures noted above occur simultaneously. I suspect there may be a common module which talks to the K-bus, but I cannot find any literature to detail this.

The car runs trouble free otherwise.

Anyone got any ideas???

The kluster is the gateway for the K-Bus, it sounds like you have a kluster issue.

Also check fuses, make sure your ignition swtich is also sending power to the proper modules to start up the communication on the K-Bus.

If not, it seems to me your IKE/Kombi(instrument kluster) has decied it doesn't like being in your E39 anymore.

did you have any luck with this fault as I have a very similar one with my 525i

so far I have replaced the basic control module on the recomendation of an auto spark and the problem has just came back , have my MOT next month and need to get it sorted

K-bus is shorted. Remove the glove box. Look for k-bus splice and disconnect one a a time until the radio can be controled by the steering wheel switch.

Was the cause or solution to this problem ever found?
