I did this mod on my BMW 120d but tried it on my Freelander TD4 and works perfect.
For this Cheap Mod you need a 22mm Cooper Pipe end stop like this.
You then need to disconnect your EGR and give it a good clean out.
Then pop the end stop in the EGR, its a perfect fit nice and snug!
You wont need to drill a hole in it like the one pictured, that is just to stop the engine management light coming on for BMW's.
