I just found some information. No CGI and probably not any 161 hp. Not yet.
AutomobilRevue
Some of it, translated by Alta Vista:
Under the plastic cover the engine looks hardly differently than the two-valve TDI. Remarkable is the absence of the hydraulic pump for the guidance assistance, that takes place for the new gulf platform electro-mechanically. The AUDI A3 has this steering element already.
Since the first four-cylinder TDI in the AUDI at that time 80 was presented in the year 1991, VOLKSWAGEN of this 1,9-Liter-Zweiventiler built not only approximately 12 million pieces, but set always also the yardstick in the 2-Liter-Dieselklasse. The pallet of the 1,9-Liters is enough from the Polo with 47 KW (64 HP) up to the gulf with 110 KW (150 HP). Already 1999 presented the first Diesel, which fell below the exhaust limit values of the euro 4 (D 4 to VOLKSWAGEN). In the meantime the Wolfsburger with the new 2-Liter offers the fourth TDI for the future pollutant limit values, which further will follow. The Vierventiler is the basis for engines with higher achievement, while the Zweiventiler remains likewise in the program and are developed further.
Proven grey cast iron
For the new Vierventiler VOLKSWAGEN maintained the grey cast iron cylinder block. It received only one of 79,5 to 81 mm increased zylinderbohrung, while the cast alloy (GG 27) remained the same as with the Zweiventilern with 96 KW (130 HP) and 110 KW (150 HP). If the Zweiventil TDI weighed 160 kg according to DIN, the Vierventiler brings 168.5 kg by the higher expenditure with cylinder head and Nebenaggregaten on the balance. That is not by any means much, because the new 1,3-Liter-Fiat Diesel brings it likewise with grey cast iron cylinder block according to DIN to 130 kg. Both VOLKSWAGEN and Fiats trust also in the future in the proven material, which does not frighten during rising specific achievement with firmness problems. The foundry specialists are even good hope to be able to lower the weight of grey cast iron cylinder blocks by precise thin casting up to approximately a quarter. Thus we can be surprised.
New head
The cylinder head with its perpendicularly hanging four valves is completely new. Because in the cylinder center not only the pumpe-Duese (of Bosch) had to be accommodated, but also the new glow pin of beru, which perfect start without "Rudolf Diesel Gedenkminute" to down to -24 °C permits. Thus the Diesels start with cold weather today better than the petrol engines!
In the drillings in the cylinder head also the fuel and derivatives is contained and the electrical connections to the single solenoid valves of the pump nozzle elements. For the oil for the lubricating of all parts in the cylinder head one uses the hollow waves, on which the rocker fingers are stored. As today usual, VOLKSWAGEN uses role rocker fingers for the friction reduction. Since the valve star 45 °, one needs four differently formed rocker fingers per cylinder, which is made of 42CrMo4 in the high quality casting procedure.
Over the cylinder head for the cover of the nockenwellenlager and for the storage of the wave, on which the rocker fingers for the pump nozzle manipulation sit, a framework from aluminum is installed. The solid wave is embodied with five screws in the cheese head screws which are under so that a very rigid group results. The whole wonderwork of the engineer art with its penetrateful tightness is taken off upward by the usual hood, which contains the oil separator for the crank case exhaust.
