Long story short. Me and my friend both bought a Golf MK6 1.6 Tdi 2011 match 7 gear DSG. 50k miles. Took it to a specialist who done a ECU update on both cars. At 52k miles both cars got a flashing wrench/spanner on the gear indicators?! Both cars drive fine and the spanner only appears when its warm. Took it to a local garage and this code came up on BOTH cars:

006079 - Hydraulic Pump P17BF - 000 - Play Protection Intermittent

Specialist says pump in DSG needs to be changed (£1500 parts and labour).

Is this something programmed into the ECU? 52k miles hydraulic pump alert?
