Hi, Paul, and welcome to EM

Your 1.6 TDCi is actually the same engine as in my Peugeot and Euromodder's Volvo. I'm getting some great numbers using PNG (Pulse, then Glide in Neutral, with the engine on) and haven't noticed any engine trouble (I don't have a DPF though). Euro has problems with his, but they're not directly related to hypermiling or ecomodding, iirc.

Here are a few small things you can do:

1. Adjust the nut behind the wheel! Don't go faster than you need to, don't accelerate when the next light has just turned red, etc.
2. Up tyre pressure to 40psi (MAX - 10%) and see how that works. Once you get used to it, you might pump up to 44psi for longer trips and/or when alone.
3. Partially block the grille. Block the rest during the colder months. You might also block the upper grille and make the lower grille block openable. If you have an intercooler, then you don't want to block that part. Turbodiesels are most efficient when the engine is hot and the intake air cold. Insulating the engine helps, too.
4. If you have a place to plug in, then install a block heater. DEFA 412512 is the heater for the 1.6 TDCi/HDi, it works wonders year-round
5. Don't kill your engine until the turbo cools off. I EOC only when I expect to coast at least 600-800m, or when coasting to a long red light, but I let it idle in neutral for 3-5 seconds after pulsing.
