hi all,


my first post here


I have a problem, I had the error code do I changed the glow plugs but the error persist and I double checked the glow plug that I have removed was good but I changed it anyway.


since then the error is still there do you guys think it is the relay?


another problem that I have is some flat spots around the 2300 rpm.


car has full service history new MAF, new MAP, de-flapped, new glow plugs, AGR cleaned but these flat spots persist.


thank you in advance
