I have three sensors available I bought a set but only needed one

just get a tyre place to fit them drive 4-5 miles and the car finds them automatically 

Ok so firstly a leaking induction system will cause the dpf to fill up rapidly as this will create smoke and soot (could have been the original problem) the size of the engine and type of dpf should last the life of the car so long as a decent run is done now and then you could have been ripped off I'm afraid

No problem hope you manage to get it sorted I have to admit I gave up out of sheer frustration with my portfolio s real pity as it was a fabulous car let down with one problem after another 

also pay attention to which way you put the bolt in mine being the 40mm long one was digging into a pipe when I got it back and had to turn it around so the excess thread was facing towards the rear of the car and off the pipe work 

good luck

Yes M6 40mm is what is normally supplied although 30mm is plenty long enough also fit a nylock nut will stop it rattling loose ;-)

screwfix will probably be your best bet you may also be able to get from a local B&Q
