Odd Parking Light Issues - 2005 V70 SE D5 Auto.

[JayMan71]

HI All, advice needed please,

I've got a 2005 V70 D5, bit of a learning curve having spent 15 odd years in 850s and P1 V70s.

I noticed the other day quite by accident strange behavior from my parking lights. If the car is switched off and you try the parking lights straightway nothing happens, no lights and the green light on the switch is out, but leave it for say 5 minutes and all is good. With engine running, they work as expected. All other light functions work without issue. It's as if there is a delay for a few minutes before parking lights will engage after switch off, is this normal P2 behaviour.

Leave the car a while, overnight etc and they work first time.

I have changed the switch with a known working one which made no difference.

Any suggestions on what to check next?

TIA

PS the 2 sidelight bulbs in the headlamps and 1 side marker bulbs are out, just waiting for the weather to improve so I can pop bumper.off and get.lights out to replace.
