Hi. Before I took the vehicle in for a service it began to have intermittent power loss. Usually after cruising on the motorway or steady driving. MB Indy said there were two codes related to the egr 149A and 155D and this was probably the cause of power loss. Suggested replacing at £350 + vat. Decided to get it deleted and eco mapped. Certainly goes better now but have yet to run it to see if it improves the mpg. Power loss is still there. Can't check to see if there are any codes as the reader I have is now not working, it was before. that may be a remap issue, will discuss with tech that did it. I've read it could be a maf sensor, a leaky orange seal on the air intake.
Anyone any further ideas?
