2010 Polo rear lamp problem

[disad-vantage-d]

My wife informed me yesterday that the bulb warning lamp had illuminated on her car. I checked and discovered that the rear nearside position lamp bulb was not illuminated. I obtained a spare bulb and removed the lamp cluster only to find that the bulb appeared not to be blown. I refitted it and connected it up and the bulb lit.
I refitted the lamp cluster only to find that the warning light was again showing and the bulb was not lit.
I repeated the process and pushed the bulb into the fitting firmly and refitted the unit. The Bulb was lit and the warning lamp not showing.
She has driven to work today and informed me that the warning light was showing again when she arrived at work.

Has anyone similar experience of this and can suggest a fix?

Definitely the correct bulb you're using? That's been the cause most the time I've heard of similar problems.

Unfortunately the DRL setup on a 2010 Polo means the rear lights are illuminated constantly which is probably why its needed replacing in the first place!

Yes. It's the correct bulb. It's actually the bulb that was already installed as it hadn't blown.
It' s a strange bulb all glass - not unlike a G4 halogen bulb you use in household lamp. It pushes into a sprung contact on the light unit.
