hello, I have a 2011 v70 d5 ex-police with 215k on the clock. Getting the error code which refers to egr valve stuck open. Also when engine is ticking over it sounds like there is a bass speaker under the bonnet. We get intermittent loss of power when accelerating. .
I sprayed egr cleaner in the air intake but even tho improved the power loss it hasn't solved the problem.

Has anybody got any ideas ? Any help appreciated.

Thanks
Neil
