Mk1 Fabia flickering lights

Recommended Posts

The only time I have seen flickering lights on my car is when the steering angle sensor was packing up.

Been having any power steering related trouble?

Agree - probably just need to replace the steering angle sensor and the flickering will go away and the power steering will be more consistent.

Well, I'd want some proof it is that before diving into stuff - VCDS scan for starters :)

Really need to measure voltage right at the battery terminals, with engine idling.  Do that with nothing extra electrical switched on and then again with say headlights on dipped beam and cabin fan on 4.

Also, does your battery light in the cluster come on when you switch the ignition on (before starting engine) and go off again when you have started the engine?

 

Do you own a battery charger?

Have you investigated the source of the current drain mentioned earlier yet?

 

Edit: Having just looked under the bonnet of a colleague's 8v 1.4, it's super-easy to measure the voltage right at the alternator on this engine, there's nothing in the way. Is yours the 8v/mpi engine?

 

That's another really useful measurement to see whether the alternator itself is putting out the right voltage, because it can only regulate itself relative to local conditions and has no feedback on what is going on at the battery. So: red meter positive probe where the thick wire attaches to the back of the alternator, black negative probe to somewhere metallic on the body of the alternator.  That way you exclude any bad connections elsewhere and get to see what the alt is doing.
