E 270 Cdi Loss of power

[germerc]

Help

Recently my car was serviced at approx 84 k filters etc changed
I had a power loss on motorway after about an hours run took it to the Indy at gateshead and kindly he reset the EGR valve which showed a stored fault and alls well, however 2 weeks later or so same trouble again today again after about an hours motorway cruise ??? may need replacement here

has any one had similar experience ???,

Also at low speeds in traffic there seems to be a lot of Diff/whining sound
and lumpy changes although gearbox oil has been Glycol checked & re-newed about 10 k ago again any advice or possible causes appreciated

Thanks

id say its your egr valve sticking did he just erase the fault ? or clean it out ?
