PD or Common Rail

[Muttley]

I don't look in to the Mk.2 Leon section very often, but there might be some comment in there.

The 140 BHp TDI installation I'm thinking of is that in the Mk.2 Leon that you mentioned above, which is PD and I know has an FMIC. I wouldn't be so bold as to generalise that "Sport" = FMIC though.

Turning down the EGR on a later TDI engine is harder - I don't know of a way using VCDS, for instance.

Thanks again Muttley does your knowledge extend to the other marques (ie VW & Audi) with regard to TDIs? The reason I ask is that the misses has just said that maybe a Leon Sport is not quiet me at our ages?!? Think she was put of by how the salesman hacked around in it !And maybe go for a MK 2 Jetta Sport or a A3 Sport (5 door) we had decided on an Exeo Sport last month but then decided maybe a bit big for the leasure driving we do (country lanes - Cotswolds etc especially in Winter) Paul

Exeo is a larger car, certainly, Passat-sized. I think you mean Mk.5 Jetta, the Mk.2 dates from the mid-80's. All three cars (Leon, Jetta, A3) are based on the same Golf Mk.5 platform, so the differences are in styling, interior finish and the number of toys. Prices will be highest for the Audi and lowest for the Seat, simply because of the way the badges are positioned in the marketplace.

You talk of "Sport" variants of each car. This would tend to mean a car with firmer suspension, possibly lower, with wider tyres and less of the luxury toys inside (e.g. no CD changer, cruise control heated seats, that sort of thing - they'd be optional extras). That's not universally true, but generally Sports means driving experience over passenger comfort, but not to an extreme.

For me the best part of my Toledo TDI 150 Sport is the factory-fitted Sports suspension. 15mm lower than the Comfort model (fun getting a jack underneath), firmer sprung and better damped (Bilsteins) it stays much flatter in corners, still keeping the wheels on the ground, but is still comfortable over potholes. Some speed bumps do scrape the undertray though.

You must decide what you want from the car. If you want to dial back a notch from the "Sport" experience, the PD 130 in the Mk.1 Leon/Mk.2 Toledo is ideal - better response low down, softer ride, just not quite so tunable. I'm not sure what the equivalent in a Mk.2 Leon would be.

I had another go in the Leon last night and thinking about what has been said re emissions etc, then surely to have to have the Engine buzzing over 2000RPM to get anywhere is going to increase emissions ? I compared the same journey Town & the Motorway and my old 110 I could drive comfortably with gear changes at or just below 2000RPM in the Leon PD it was always in the 2000-2500RPM range.

The other thing is once I lifted off during gear changes I could hear a Whistle, much like the noise I've heard before when the Turbo is spooling up...........but in this case as I had just lifted of the gas it can't be spooling up..................it's timing is much like the waste gate on Powerful Petrol engines.
