Dave,
can you answer me two quick questions?
1) does the front engine skid/under tray interfere at all with the oil pan drain plug? I couldn't tell from pictures if you need to remove any of it during an oil change.
2) a quick eyeball at the parts tally puts the figure at close to £700! For us yanks across the pond that comes out around $850, or in another way, almost 4% of the price of the base GTI @ $25,000. Considering we pay about $2.50 a gallon of gas, which nets about 30-35 miles, the practical purpose of increasing aerodynamics for saving 'fuel economy' seems mute, no?
I suppose this has a practical application for reducing under carriage damage by rough road conditions, and reducing cabin noise. Its difficult to put a price on that.
1. Just use an extractor and you never have to remove the skid tray.
2. I'll have one for sale for less than half that amount in about a month when I get back to the USA. Picked up a spare when I installed mine but they're so incredibly strong that I'll never need to use the spare.
