I bought a GT TDI golf two years ago,
she has an exhaust system a K&N panel filter, and REVO Remapped to near 200 bhp and 300 lb/ft and she's lowered,
The engine code is ARL (=150bhp),
The 6 speed came on the 115bhp gttdi also so don't go by that!
I drive the heart and soul out of my golf all day every day, I have clocked up 40,000 KM on her since I bought her,
I changed the clutch once when I first got her,
I burst the sump once, my own stupid fault (hump backed bridge
)
And I have had to replace a few intercooler pipe clips and rubbers on maybe 3 occasions (stupid design)
Other than the above, no problems at all, I love it,
She averages 40-45mpg as said with the throttle nailed to the floor, I have done 50+mpg driving normal with babies asleep in the car,
Serviceing is so easy with the oil filter right infront of you when you open the bonnet and rear brake caliper need to be twisted as you push them back for pad swap (that one had my head wrecked for ages)
The EPS Electronic Stability Program kicks ass, I love playing with it, ie. fire her into a wet round about, way to fast and big scandinavian flick, (just make sure you are pointing the steering wheel in the direction you want to go, and it's like the hand of god just stops the skid and sends you back on your way!
Great craic! and she's a pig to drive without it,with to much wheel spin and under steer!
Hope this helps! and you can have a shot of mine when you are over this neck of the woods for the trackday!
