Smoke in engine bay: VW Polo 1.2 TDI Mk5

[SamRH]

Hi guys,

A little help would be absolutely grand.

I've got a 1.2 TDI Polo Match 2014. I noticed some light smoke coming from the front headlight bonnet panel gap a few weeks back. I thought nothing of it, as it's been cold lately. I've seen it a couple times since, so I checked again this evening. The smoke is coming from one of the hoses at the back of the engine bay behind the engine block.

I have my car booked in with the garage on Monday, but I just wanted to see whether this was anything serious (should I be driving the car?) or whether it's something that can wait until next Monday?

Any help anyone might be able to give would be a great help.

Thanks for your time, guys.

Best,
Sam
