Hi. I've got an intermittent power loss fault (only occurs for a split second, a bit like a misfire) which has been diagnosed as a faulty EGR valve. The problem is that I've been quoted £600 + VAT to replace the valve, plus flush the fuel system and fit a new fuel filter. Does anyone have relevant experience? Do you have any thoughts on removal/refurbishment of the EGR valve - i.e is that worth considering? The problem isn't a killer right now in that it doesn't happen much, but I'm guessing it will get worse. Thanks in advance.
