Hi,
Did the egr clean out on my 2007 with 130,000k about a fortnight ago. I was indeed surprised with the build up. I plan on keeping my vehicle for a while to come yet and don't want to do that job ever again.
There was mention of this module on about pg55 on the egr thread I came across and decided to give it a go. I fitted it today.it was all very straight forward to fit with excellent instruction provided. In the future I will update this thread with my thoughts for anyone interested.
