Again, this is a boring diesel concern. I believe that I have read all threads about diesel and driving in city. I learned tricks to look after a diesel engine such as catalyst, long trip on the weekend, good quality fuel and driving skills to prevent DPF from clogged. I am still sitting on the fence to choose between diesel and petrol.

I am looking for options between Passat TDI wagon and 132TSI Tiguan. Both cars are good to me. Just the engine makes this very difficult. I prefer a TDI because I am ready to Think Blue and I want to get new experience from diesel. But I will be driving it between Ryde to Balmain (12 km one way) during peak time. This takes 25 - 30min one way every morning where you can imagine the car speed.

How often do you think the TDI wagon would get DPF light on in this case? In my case, is diesel engine a good idea? Does automatic DSG has less control than manual to prevent DPF from clogged? How often does your Passat TDI get DPF light come on? I had test drive a passat TDI 2 weeks ago. I feel it like a heavy car. I have to keep press acceleration to keep speed steady.( Sorry my English is bad ) Or speed drops quite significantly. So I hope and guess the computer is smart enough to keep revs high so that the car would clean itself more often without running on highway. Is my guess practical?

In addition, I question the TDI + Blue motion package. We all say diesel engine is good at long trips. During these long ones Blue motion tech would be useless. I believe start/stop system is designed and used in traffic/city. So it sounds like TDI and Blue motion should not stay on one car.

Appreciate for any advice.
