Hello!

I'm driving a Skoda Octavia MKII Combi and I'm having a very estrange issue.

This issue appears without any apparent reason, and disappear at the same way. The yellow steering wheel warning light  turns on and the brake light with a three long beeps, when this happens I lost the air conditioner, the steering wheel assistance and the gauges on the dashboard goes crazy.

Have you guys any idea whats going on whit this?

Check tightness of battery connectors; check for corrosion around the large fuses in the fusebox next to the battery.

Your symptoms are indicative of an intermittent supply to high current loads.

Can also be caused by a failing battery - when was it last changed? or checked?

I had a similar weird issue a year ago; came out of nowhere.

 

The dash lights started dying, and whenever I turned left the wipers and windows died.

 

Made sure all the fuses and relays were fully pressed in and the problem disappeared.

Hi guys thanks for your answers.

 

Yes I made a revision of all the fuses, and it looking good, no corrosion or other apparent issue. Also I've check the battery connectors and the battery it self, the voltages are fine.

 

Getting deeper on my revision I've notice that the failure start when the car start moving, for example, I turn on the car and everything is working fine, the steering wheel the A/C, but when I release the brake and the car star moving... the issue appears.

 

Still sounds like a loose connection or a connection at an earth stud. When it happens can you use a multimeter to check the voltage at a non working part and then also the volts from a failed supply directly to battery positive and finally from the negative of the failed unit to battery negative.

Alternatively, find someone locally to run diagnostics using VCDS software. This will show where there is a supply discontinuity.

 

Not common but not unknown is a battery that has an internal connection fault. Borrow another battery to see what happens.

Hi guys sorry for the silence...

 

Well I followed your advises, I've check all the fuses, and all are OK, in the fuses box on the engine and the door side as well.

I replace the battery for a new one, the other battery has death.

After do all this checks and replacements I still having the same fault.

I borrowed a OBDII scanner ( this is an universal scanner, not the official for Skoda) and it show me a failure code: P0600. I attach the screenshots whit all the info that I collected with this scanner.

Best Regards.
