Finished work today and went on the motorway to get home. Travelled at 70mph for 13 miles got home and parked outside my home. I realised I had to go to the post office so started it back up but it had no power at all. I then tried revving it up but it just was so sluggish even when moving off. I then switched the engine off waited 2 mins and then it seemed fine.
Looked up the EGR valve and it seems you are right all symptoms point to it. I can either replace it or clean it. Will need to ask a mechanic see what he thinks EGR valves are expensive.
Thanks tonyav I had a lok at my egr valve and it does look clogged up. Seen the video looks simple enough to do. I was thinking it maybe best if I get a mechanic to remove the egr valve and then give it a good clean and also the turbo using the product below.
