The VW Tdi 1.9 comes in various states of tune as mentioned.
I one an Ibiza Fr which packs 130bhp and more torques than the car can handle to be honest. It fairly shifts along and will pull like an express train even in 6th from quite low speeds. However:
A point I take from a lot of these posts is that people seem over concerned with which gear to be in at a certain speed; rather than which gear to be in at a
certain speed combined with road conditions.
Eg Around town and in a 30 limit I will rarely use 4th gear. Why? because 3rd give me more ooomph to avoid hazards whilst allowing me to keep within the limit using engine revs. The extra fuel used is minimal in a car that will easily achieve (according to the onboard computeer) 60mpg +.
Sure the car could be driven in 4th and will pull at that speed even in 5th but there is not the level of control/avoidance power I want.
Likewise on a motorway when the going gets busy I may well be in 5th rather than 6th; which gear will depend on the speed
and the conditions.
Ok so in an exam situation you may have to show you can use 4th for a limited time in the correct conditions.
The gear you need to be in is the gear that gives you the best control according to what you can
see.
For learners:
It is not a race to get into the highest number gear as soon as possible. It is your job to show that you understand how to use the engine compression to control the car.
Though as mentioned above you should show, under exam conditions and traffic and conditions permitting, that you are aware the car has more than 3 gears
I'm not bothered about the old Romanians and Bulgarians but the Old Etonians scare me rigid.
