Very sick C30 1.6D Anti polution etc

[Rossco1962]

Hi Folks

I posted a long time back about the trouble i was having with my better halves car and this was given to a local garage who stated the DPF was blocked so i fitted a new replacement and whilst i was at it replaced the turbo cartridge and the guy replaced a vacuum hose to get the turbo to boost and repaired a split in the hose that goes from the intercooler outlet back to the inlet manifold.

When i got the car back it did run a bit better then started to mak a hissing sound like a boost air leak but couldnt find anything obvious.

So first thing to do is find out where i can get an anti polution service performed or is this a DIY task as there is a tank at the rear of the car that is meant to be topped up apparently and also where can i get replacement hoses that go to the inter cooler from

Has any one else had these issues. I'm based near Portsmouth and have read the fault codes but find it hard to get good advice.

Can i use FORscan to read the fault codes
