cordobabrendy said:when engines are cast (made) they all are done the same way, when they are built up some are slightly more powerful than others due to imperfections/castmarks in manufacture of the engine. not all 100bhp engines put out the same bhp, some are a bit more, some slightly less and most are around the 100 mark, same goes for any other make and model of engine out there.
Mr.Bean said:I'm not agree with you cordobabrendy.
20Hp or in this case 20% more power than factory specify is too much . You told that some engines are more powerful and some engines are less powerful. From your teory conclusion is that some 1.9 Tdi PD100 is 120Hp and other is 80Hp. Its not possible, for example 1.9 Tdi PD130 would be 110 Hp and this engine will be slower than PD100 with 120Hp.
The diference between the fastest and slowest car with same engine is normaly not much than 5% and this diference you will notice only if you are specialist.
I'm driving more than 50 diferent cars (Seat) every month because I'm service manager in Company who import Seat vehicles in my country and I didnt spot big diferences between same models. Hope you understand me .

The way I understand it is, the figure quoted by VAG will be the minimum you will see, in the worst conditions.
therefore, in optimal conditions, a good sample will be higher.
Would imagine most PD100s in normal conditions would be ~110bhp, with the best being 120bhpish, and the worst 100bhpish, if that makes sense.
Mr.Bean said:Hello cpufreak,
From marketing view all factory not only VAG shows the best or average power figures on new engine, with the best fuel and in the optimal terms not the worst. Its belong also for max speed, fuel economy and other important parameters, they dont show min speed, poorest fuel economy etc.
I think you are wrong
cordobabrendy said:mr bean, i never said there would be a 40bhp gulf between models, some are more some are slightly less, they cant have too many less otherwise advertising standards would be onto them for trade descriptions act breaches etc. if you drive one or a hundred thousand new vag cars a month, they arnt run and as a result wont be putting out its best power anyway.

When my car was standard, which it was for 9700 miles, I did quite a few long runs (3600 miles in 4 days), I regularly exceeded the quoted economy figures, and on a private flat road, went to an indicated speed which exceeded the quoted figure, and have since through the use of my origin b2, verified that this is accurate to within 2-3mph at the speed in question.
my car also rolling roaded as standard at 144.8bhp once at 7500miles, and 149bhp at 9700miles...
so either my car is a good sample (unlikely I would guess), or iit backs up what I was saying.
if you can't get the economy/performance figures from your car which vag quoted, I'd be having words with your dealer.

Andy's car is a PD130, so I'm not sure what numbers you're using to get 3%, but they're not the right ones.
