Cause I have been bored at work, I decided to clean my EGR. Everything working fine, just thought I would check it out.
58-reg 1.9 CDti 150 auto with 34k miles.
Moderate amount of soot. All moving fine. Took solenoid off which was very free.
Valve moved ok, but when I had cleaned it and lubricated it, it moved easier.
Put it all back and working fine.
Should be good for a couple more years.
