Gear problems

[dashdespatch]

Hi I have a 2017 2.0 tdi every once in a while maybe 100 miles ot won't go into first gear eventually with a lot of wiggling it will go in and work perfectly for another 100 miles it seems to be worse in heavy traffic 

Dealer has fitted new clutch an bearing still no improvement

My mum had a similar issue with a mercedes. It transpired it was a failing synchromesh. 

Might be worth looking at the gear linkage too.
