It's a Ford/PSA engine. But there are some new derivatives of it in Peugeots. The 150PS is particularly good. More flexible than the older 136PS. Yes, it will have a Dual Mass Flywheel and these have been a problem in VAG DSG transmissions. Powershift is the same sort of transmission, but it’s only been around for a year or so and I have yet to hear of any failures of DMFs with Powershift, or even many in PSA drivetrains. I'd try to run the car exclusively on BP Ultimate diesel if you can. No need for additives with that because it already has them.
