I must add - mine is a MK2 without DPF and could only remove the front part of the shield. It is a very tight fit and it would not surprise me in the least if on some variants it was too tight to get out. (if the engine to radiator gap was 5mm shorter there would be no chance)
Also be very careful with the turbo feed pipe, at times the heat shield presses hard against this, and buggering this could prove very costly.
Not sure if my berlingo is without the DPF aswel, thanks for the tips im going to try and be as careful as i can and not damage anything just to do a simple job to remove that filter in the oil feed bango bolt.
