so upon driving home, my car went into limp mode with the coil light flashing, soon after the eml came on, i said to myself i bet its the egr, and behold, "egr valve (n18) p0403 (237) malfunction", i need my car for work and my mechanic cant fit me in until the end of next week, am i going to be driving it around even in limp or will it ruin the dpf a lot sooner? 

i would much rather just do an egr delete rather than have to remove both egr and dpf as i have been qouted £650-£750 for egr delete/dpf delete and a map, which id rather not have to fork out for, unless someone knows a good branded egr that wont set me back silly amounts

Hi Arron what is the model and what engine is it fitted with, then you may have some suggestions.
