Instrument Cluster loosing constant power supply

Recommended Posts

mitel

My 9N Polo (2002) has a issue with the Instrument Cluster.

Everytime I turn the Ignition Key on, the Trip and Clock have reset to 0KM and 0:00 and the Immobilizer doesn't always allow the Motor to be started.

Leave the Key in the run position for a second or two and it will then start and run fine.

Both Trip and Clock work perfectly once the Motor is running.

Is there a permanent feed to the Instrument Cluster that may be failing?

On a few rare occasions the entire Instrument Cluster has been dead until many lock and unlock the door cycles.

This problem has escalated over many months from being very intermittent to now being constant.

Check and if necessary clean contacts of, or replace, fuse 27 in the dashboard fuseholder.

The main connectors to the PCB inside the speedo are a known problem, you need to dismantle the unit and resolder the pins,

Thanks nige8021, that was the problem.

Removed the Instrument Cluster, dis-assembled and found all 8 pins on the PCB for the Black Connector were cracked.

Re-soldered and re-assembled and the job was done.

A quick and easy fix.

Did you have a look at the other, green connector too?  Immo problems on contemporary Fabias are often related to the top two solder joints on that one having cracked similarly to what you've seen on the black conn.
