was losing power on my 05 reg e320 cdi last week an was told i had 2 injector seals were leaking . had them both replaced but it has not really cured the problem . engine still running a bit rough so took it back to mechanic . been told i have an injector leaking diesel which is probably the cause of the engine running a tad rough ? also been told EGR valve showing fault on computer which explains lack of power . any idea how much a new 1 is or can i cut a corner an have it cleaned ? always good to get a 2nd opinion !!!
