Hi all .... just to update this
it’s a manufacturer’s defect and is getting sorted through warranty . Happy to report my local totton vw commercial center have been pretty good and nice and easy to deal with .
Thats good news.
My kombi went in for a metallic rattling noise. They (listers in coventry) tried to charge me 150 quid as noise was caused by incorrectly fitted brake pads.
I had only picked the van up from them 8 weeks before.
On a side not, the haldords 3 tonne trolly Jack is great for the price.
