Hi guys, this is my first post but I've been a follower for a while.
I changed the haldex oil in MY16 Octavia VRS 4x4 DSG today. The car is under 3 years old and has covered 16k miles.
The oil change itself is easy and should be well within a home mechanics capabilities. I was lucky to have the use of a lift in a mates garage but ramps would do the same thing.
There's alot of uncertainty out there about the intervals of when it should be changed etc. My advice to anyone is get this oil changed every 15k. From now on mine will be done anually. With the Gen5 haldex there is no filter and the gauze on the pump is very small. It gets completely gunked up and my guess is it will starve the pump of oil. I've included pics below of my pump when I removed it today.
I sourced my parts online. The oil, G 055 175 A2, was bought from a Skoda dealer (Dennis Horton) for £24. Replacement o-rings and bolts for the pump were sourced through eBay, link below.

Dealers charge up to £80 for this kit!
Below is the evidence this oil needs to be changed more frequently than the manufacturer recommends. With the oil changed I already notice a difference, my driveway requires reversing up an incline. Before the oil change I had to rev excessively to get the car to move up it as if I were riding the clutch. With the gauze cleaned and new oil it's zooming up the drive with hardly any extra revs and much more responsive!
