[volkswombat]

I noticed the other night when parking my car (Volvo v50r t/d) at idle ,move the steering wheel (so power steering pump operates) and the headlights dim. I've nernerver noticed thius before , sound normal? Or something getting brokener that needs fixing?
Maybe related or not, also noticed of late a rattle from rengine between 1000 and 2000 rpm, happens in gear,  out gear,  driving , stationary, clkutch in or out.

If its an electric power steering pump I'd say that this was normal as I guess that they take a fair amount of power.

If hydraulic then no.

No idea about the rattle I'm afraid, we had one like it on our C15 van and after spending ages trying to pin it down it just went away one day.
