Hi All,
My CLK270's EML light came on last night and is still on today, I plugged in my eBay special OBD reader and its thrown up a PO401 code which comea up as a EGR error - Insufficient Flow.
What does that mean and how serious is it? I cleaned the EGR about 2 or 3 weeks ago and haven't noticed anything else, oh and I was absolutely caning it last night before I'd seen that it had come on.
