I've got a 1.7 tdi corsa c and lately I've noticed that I'm getting less and less mpg, are there any common problems with these engines that result in this? It's 02 reg

Do a leak off test on the injectors - they are known for this.

Also make sure you've had new air / fuel filters in the last 30/40k.

Google doing a common rail leak off test - it can be done with a kit off ebay or with some tubing (bit messy though)

Or any local diesel injection specialist can test for you, usually 30/40 quid.
