How to (LR Discovery EGR Removal)

I'm not going to write a complete post on this as there is already a very good guide available by Simon Ward-Hastelow, 20th Jan 2007 via Difflock HERE (Direct link to guide).

I would however add the following points.

If your going to be taking off the pipes, replacing them with new ones, I would suggest you might want to also flush your intercooler out and fit a Hyclone, and replace your turbo pipes whilst your under the bonnet. Keep your eye out for posts on intercooler flushing (rss and atom feeds available). Both the Hyclone and Turbo pipes can be bought via Ebay or other retail outlets.

Flushing your intercooler will clean it out and allow your engine or turbo to breath. If you don't, then your simply going to be pumping oily gunk down your new pipes (I know you will at some point anyway, but the whole point is to limit this as long as possible).

Replacing the turbo pipes ensures that you will not be suffering from turbo hose weeping and gives you an ideal opportunity to insert a Hyclone into the pipe.

Although, it may seam overkill - I'd also consider replacing the viscus fan with an electric type which will assist in increasing fuel mpg and allow you to control when water crossing. I appreciate that for some, removing the egr is all you want to do which is fine.

The EGR tends to fail by sticking open. Some symptoms of this is smoking or sluggish performance. On removal, reports indicate that you get improved performance and mpg without effecting the MOT. Combine this with 'De-Cating' (covered in the future) and you end up getting closer to the preferred performance of the tdi.

Don't forget, if you havn't already - why not subscribe so you don't miss out on new posts.
