Dec 5, 2000 Location Finland TDI Golf IV Variant powerdiesel Mar 27, 2001 #1 VW has done an excellent job confusing me on this matter. I have understood that the 90hp and 110hp versions have different bore/stroke/piston etc. and the 115pd is of course again different. But there seems to be even more versions.

There is no such thing as NA AAZ. 1,9 NA engines have indeed longer (150mm) rods than turbo engines (144mm) Pistons are same 6mm shorter. All 1,9 diesels have oil squirters and stroke is same. Some later NA's have same crank as TDI. Logged. Displacement alone is not a good indicator of power output, particularly for turbocharged engines. The mapping is probably the most important factor, which determines fuelling, boost and injection timing. My 1.9 PD 130 can be remapped to at least 170 simply by changing the software. The 1.9 is an 8 valve engine, whereas the 2.0 is 16 valve. For my diesels, both IDI and TDI, which I have re-ringed (never needed pistons), I would not idle the car much, but rather drive it fairly hard, and try to avoid extended times of lower power settings. I would consider a two pronged approach: 1. Review breakin instructions, and 2. compression check and leakdown check the engine on each cylinder. Unlike the 1.9 TDI, the 2.0 TDI is plagued with a laundry list of potential problems, including the oil pump, the injectors, and the dual mass flywheel. If you can live with the lower power output of the 1.9, the 2.0 is best avoided. . WE CAN UNDERTAKE ENGINE CONVERSIONS AS WELL AS BRAKE UPGRADES.

I think it's to do with the 1 bar atmospheric, you need to add that in the mix so the sensor needs to be capable. Safe max is about 21.5psi for the VA which is about 1.5bar so add the atmospheric and you're at the 2.5 but the 2.5 can actually read higher than 2.5 so it works. The engine range of the Passat Alltrack consists of two 2.0 litre TDI with outputs of 103 kW/140 hp & 125 kW/170 hp and two petrol engines, 1.8-litre producing 118 kW/160 hp and 2.0 litre TSI producing 155 kW/207 hp. When this problem became all too apparent, VW and Associates were likely in the middle of developing the new TDI engine, this used the same block and crank as the 1.9 TD, but different heads and pistons. The engineers looked at this marginal integrated key, and the quarter moon spline on the crank nose and decided to move on to a new sprocket Dec 5, 2000 Location Finland TDI Golf IV Variant powerdiesel Mar 27, 2001 #1 VW has done an excellent job confusing me on this matter.

is the 1.9 tdi a good engine
