Just got a 53 plate tdci 130 ps with 140,000 and service history and when driving back as I got about a certain rpm glo plug light started to flash, went in limp mode and a couple of times engine stopped altogether then switch of and switched straight back on and no flashing light but soon as hit rpm again back on and back in limp mode there's no smoke and light not flashing straight from switch on, I've spoken to a friend who's a mechanic and he seems to think that injectors might need recoding as ecu looses memory from time to time, just wondered if anybody else experienced same problem as I'm hoping it's not injectors with the price, if anyone could shed some light would be much appreciated
