    Did you have to remove the front end of the car off to get the DPF out

    No not completely just remove the bumper and loosen the bolts in preparation for front end removal and wiring plugs . Slide front end forward a few inches and the dpf will come out from the top.

    When you say undo the bulkhead what do you mean exactly? Did you take the driveshaft off?

    You can remove the steel bulkhead panel just behind the engine it gives you all the space you need to work on the back of the engine . No I didnt take driveshafts off there is no need everything can be done from above except a few dpf bolts if you are taking out the dpf.

    Cool ok cheers, I've started taking mine off today but currently stuck on the bolts that join the dpf to the exhaust there just isn't any room to get anything on them

    When you take off the bulkhead panel you can get through to the 3 bolts holding the dpf to the exhaust using a few long extensions. You can see all three bolts heads if you remove the airbox. The bolts are torx spline heads . To remove the bulkhead panel you have to disconnect the heater pipes as they go through the panel.

    You do know on that engine the egr cooler is attached to the dpf also. You have to take out the egr cooler to get out the dpf.

    Thanks mate lol, did you re-use the gaskets?

    Yes I know they are joined together pretty much.

    I think the only gasket is the one for the egr cooler to the dpf/scr cat. I didnt reuse because I ended up fitting a new egr cooler in the end but I would have reused it if I was putting the old one back in.

    What's wrong with your car?
