Drove the wifes FL2 last night and noticed a slight rumble when turning left ,can;t hear it when straight or turning right.Any ideas guys,wheel bearing ? if this how to check ? or do I let it get a bit louder to help locate it

Is it speed related ie does the noise speed up and down when the car does?

Might not be relevant to your case but last week an elderly (ie even older than me) neighbour dropped by and asked me if I had any idea about a squeeking/grinding noise when he turned left in his Audi A1 Y reg. I went and had a look and found that the discs were in a terrible state with big chunks of rust scraping against the calipers. He has had the car from new (16 years and about 80k miles) and never had the pads or discs changed! Surprisingly it had been MOT'd recently with no advisories. He now has new discs and pads.
In your case I would start by look at the front left discs and wheel bearings since they come under more load on turning right. 3 x FL1 2 manual + 1 auto

It is Dorest  FL2 MY10 TD4 GS traded in at 2 years
FL2 MY13 TD4 GS Current

He was probably still on his original tyres too.

There is also a lady in the village that takes her dog down to the beach in her car twice a day (about 500 metres each way). Remind me not to buy that one if she ever changes it. 3 x FL1 2 manual + 1 auto

not noticed the noise being speed related ?? and as I said its seems to be only turning left and not sure if you can feel it slightly through steering and footwell? new discs and pads in last 1500 miles.
