Whilst coming home from a camping trip the glow plug light / engine management light started flashing. Van seemed unaffected as I had to drive it home 40 miles. No shudders or loss in performance. Everything feels totally normal. Its a 2005 t26 1.9 with 38000. Got home. Unloaded family and tried it again. No problem this time. Light not coming on anymore. Took it for 5 min spin and still no light. Brake lights all work ok. Ive booked it into garage next Tues for them to check it over and do the oap at the same time. What things could I look at and rule out in the meantime? I fitted a double swivel base a month ago and obviously had to move all the leads and plugs from seat base to under rubber cab mat. Could this be anything to do with it ? Any ideas ?
