Yes mate that is correct the 170bhp 2.0 TDI DPF engines need to use the Longlife engine oil in 5w30 grade and FULLY Synthetic.
I learned this the hard way as the original dealer I bought the car off used PD 5w30 SEMI Synthetic oil for the first two services, leading the the DPF clogging up with a greasy type substance.
The car then needed a new DPF filter and differential pressure sensor. This was all covered under warranty luckily and fixed by another dealer as my original dealer were total muppets
