Sorry, unfortunately I don't have the coding required for MY15 and MY16, nor do I have the parameter file for 55-headlight module.

Sorry I should have been clearer it's very obviously the plastic Bush in The selector slot so a new one is ordered. A chap on YouTube did a temporary fix with insulation tape which I have done for the moment until the part arrives!  The rest of the gearbox changes very well so if I find anything more I'll go through the alignment, thanks!

I am revisiting this because I'm finally going to change the pump. I thought that both v488 and v188 were the same.    Upon inspection of the part the front pump (v188) is definitely the Bosch 965 567   The back pump v488 (pump c which is the issue) doesn't look like the same one in the front. I don't want to dismantle the whole thing to check. But is it possible the front one is Bosch and the rear one is Pieburg? From reading posts on others forums, mainly @Crasher on the issue I thought they were the same part number.

VDCS ?

@Balazs_HU, fuel consumption variations are generally difficult to account for.   A minor point but I think you may have used the smaller USA gallons instead of the larger Imperial (British) gallon for your conversions so 5.5L/100 is 51 mpg, 6.2 - 6.4L/100 is 45 to 44 mpg and 8.0 - 8.5L/100 is 35 to 37 mpg.   I have a 2014 1.4tsi combi that has only done 105,000 km and there is no doubt in my mind that the engine is a really good, economical unit....however like most petrol engines it drinks noticeably more if you use the performance or if there are adverse road or environmental factors.   Based on some official VW issued consumption figures I have seen for early 1.4tsi engines and my own experience I find it hard to believe that your car would have consistently achieved your claimed displayed consumption of 6.2 to 6.4l/100 at real 140 to 150 kph speeds. A diesel could possibly do it or maybe even a mk4 1.5tsi with it's better aerodynamics and longer gearing but that is a moot point.   Most British drivers on their roads would not have the freedom to travel at those speeds for any distance without incurring punitive fines and the same here in most of Australia where I live.  Quite honestly travelling at a true 130kph in good conditions and I am really happy to get 7L/100, which corresponds with VW claims. Obviously consumption increases with speed.   A headwind or stiff crosswind can adversely affect consumption by 1.0 to 1.5L/100 at 110kph in my experience. Equally a tailwind or travelling at speed in enforced reasonably close proximity to other traffic can benefit consumption by similar amounts.   If your car has a real consumption problem that is only manifesting itself at higher speeds then it probably has to do with the higher airflows. As @Rooted says check your air-filter is clean as a first step but it gets more difficult from there. Other possibilities may be turbo related or maybe the variable valve timing is not performing as it should? I imagine the only way to disprove either is to put the car on a dynamometer and see if peak outputs are below par?   Personally I think your current consumptions at both low and high speeds are quite realistic.
