Hoping one of you can give me some advice about what might be wrong with my car (A4 avant 1.9 tdi diesel). About a week ago I drove onto the road and started up the hill. Immediately I noticed a very poor response to the accelerator. I coasted back down the lane and drove up the drive. After a quick call to hubbie overseas, I started the car up again but there was zero response from the accelerator. The glowplug light was on (the curly symbol - not the light I have to wait to go off before starting up the engine, which we call a glowplug but is probably called a heater plug or something). Hubbie had a shufty on t'internet as asked me to check the brakelights were working. They were, but that reminded that when I cleaned out the boot the day before that the stuff I had in the little compartment behind the lights was sopping wet - water had got in somehow - might be coincidence. Just now, was about to arrange garage to collect car - gave it one last try and presto, it's revving up a treat. But I would be nervous driving it in case the same loss of power occurred. Sorry for the rambling post - I'm not good with cars, so hope I've explained it properly. Anybody any idea what the problem was/is.
