Does my Astra have a DPF?

Hi Ger,

Right, this is a very good question - and by very good question, I mean that we don't have an exact answer. The tricky thing is that SOME Astras of that vintage were fitted with diesel particulate filters, but not all. It depends on the spec of the car and whether or not it's manual or automatic. The easiest way to tell is to have a look underneath the car - if the exhaust has two distinct sections, there's no DPF. If it has three distinct sections, it has a DPF.
