    Popped the hood and took a look at what was in there. 1st pic is of the plastic/foam engine cover.

    2nd pic is labelled with the major components. A few comments:

    I've noticed a lot of new cars putting the ECU in the engine bay, including the mk7 VWs. Why is it in an area where it'll get cooked by engine heat and the contacts are exposed to water? These used to be in the cabin or under a cover. The battery releases gas, I don't think they can react with ECU since they're weather sealed but you worry about the contacts. Is it to save money on wiring and faster assembly?

    The fusebox and relaybox to the right of the battery have stamped markings to NOT pressure wash them. I don't know why is using a pressure washer on engines but if you have been, only use cleaner and light hose pressure. I also cover the alternator and any electronics boxes.

    Since I'm a performance minded person, I have to point out one of ugliest intake pipe I've ever seen. It has a sharp flat bend into the intake manifold which is horrible for smooth airflow. I didn't remove it but the pipe looks like it flattens out in that section. 90 degree bends are very restrictive to airflow. If the ECU wasn't there it could have a smoother bend and that would be free horsepower.

    Engine uses a timing belt, requires changing every 97,500 miles (I guess if you go another 500 miles the engine blows up, lol). I would also expect to change all rollers/tensioners.

    I guess they read about the recall on TDI engines where vibrations caused fuel line leaks. I don't have the slighted clue if the fuel lines going from the fuel rail to the injectors are wave tuned but they have rubber dampers on them. Do NOT remove the rubber dampers because those are there to dampen any weird vibrations that could occur and cause fuel to leak on top of the engine and next to a red hot turbo...that would not be good.

    Injectors appear to be solenoid common rail injectors.

    Maybe I missed it, but does it use an EGR?

    Yes, the Chevy Cruze diesel uses an EGR. There are some more pics of this engine online from various sources that show it but when I looked I could see the EGR.

    I wish the engineers could get a way around it. Or get another way to get rid of crankcase fumes/breather.

    Well at least the ECU is easy to get to. Pulling it out of my Mk6 Golf was a PITA!

    Who builds the High Pressure Fuel Pump for this puppy, and what is the HPFP model number?

    bosch does but it's a CP1H . No relation to the TDI pumps. Used in Europe for a while.

    What is the fundamental difference between the CP1H and our CP4.1?

    Does the CP1H get lubricated by the diesel fuel, like our CP4.1?

    In the CP1H, is the fuel that lubricates the low pressure pump plunger/drive shaft cam combo also diverted directly into the high pressure fuel delivery port to the common rail, like in our CP4.1?

    CP4.1:

    Can't comment on tech differences other than it's an older family and that it's lubricated by diesel. All diesel pumps are lubed by diesel fuel. The Chevy Cruze diesel has not had the sales volume of the VW-Audi TDI so I don't know about reliability and HPFP failures. Plus, the cars are all still brand new.

    So this is a TDi engine but with a Chevrolet Logo?

    No, the engine is completely unrelated to the TDI engines. The engine is a GM family engine with a Bosch HPFP but that is also a completely different HPFP family.

    Technically speaking GM does not make its own diesels. This one is designed in Italy and built by the Germans. GM wont ever make a turbo diesel themselves, and be successful.

    Did GM sell off its OPEL ownership? If they didn't, then those German Opel engines are GM in every way.

    I thought Fiat has a hold of the diesel market now in Europe?

    great find on those videos! The 3 piston design looks like it would be easier on the pump.

    I saw three pistons in that animation. Was I wrong?

    Three pistons would mean a three stage pressurization cycle.
