Octavia MK2 2.0L Diesel loses all power while driving

Featured Replies

Hi all.

 

Currently stuck on the side of the road.

 

My Octavia spontaneously shut down while I was driving. All electronics when blank, and the engine stopped. I'll pulled into the hard shoulder, and the car wouldn't give any signs of electrical or mechanical life when I turned the key.

 

After 5 minutes, it started again, but the power steering light was on and was orange. I drive down the road 300m, then the power briefly went off again, but the electrical lights came back on on the dashboard as if I was starting the car.

 

Any thoughts?

I know when you disconnect your battery and reconnect, when you drive off your power steering light illuminates for a short time, then it goes out.

so maybe battery terminal is loose(very loose).

Sounds simple I know, hopefully it's just that.

Good luck.

Thanks Ardle. Just here with AA. That seems to be ok. There's also no faults showing up. It's a bit of a head scratcher. 

 

If I start the car, it will run for a few minutes, even if parked, then just cut out.

Sounds like an electrical problem somewhere with the power supply.

What did the AA say?

Yes, it seems to be electrical. The AA weren't able to root cause, but the car was able to limp home for me. Planning to bring to an electrical mechanic as soon as possible.

 

The AA mechanic was able to occasionally replicate the issue was shaking the fuse box in the engine, but everything looks solid in the fuse box. No corrosion visible. Looks like either a loose/faulty connection underneath, or maybe corrosion underneath.

 

Will give an update when I get it sorted.

Yeah could be..... have you checked the fuses there to see if any are blown?

 

Keep us updated please :)

Quick update...car is with mechanic and it looks like it's an ECU fault. Awaiting details.

have a look at volfs project thread, he had some issues recently with water ingress getting into the ECU
