[Mk2] [NA] 4 Warning Lights

[psummers]

I went out for a spin after washing my car and after about 1/2 a mile 4 waning lights came up. The battery light came up first shortly followed by the malfunction light, low oil light and engine fan light. I pulled over straight away to visually check nothing was wrong in the engine bay, all fine, so I turned around and went home.

The engine does seem to be making a whining noise that you can hear in this video.

I did diagnostics check and no error codes came up. I did a quick search on here and it seems to point to an alternator fault but a new anternator was put in earlier this year.

This is my dash with the lights (note the handbrake light is on too!):



Any ideas on what it could be?

could be your alternator got a soaking,
during the washing of your car.
give it a chance dry out.
and try it again.

Tried it again this morning and the waning lights came on once I revved pased about 4000 rpm. I checked the alternator belt and it seemed tight enough. Could it be some sort of sensor issue?

Took it into a garage this morning, looks like I need a new alternator

yeah, thats typical alternator failure.
You can test your voltage on the battery with the engine running, should be about 14v.

Battery indicator wasn't sitting at the top & the noise it was making sounded like the belt was just slipping on the pulley to me.
