A couple of weeks ago, I refilled my car with diesel in Winslow (a town near where I live). It was very cold that day. The following day, I was overtaking a lorry at the beginning of some dual carriageway and my car spluttered, went into 'limp mode' (I understand it is called). Two amber warning lights came on: the EPS
one and another which said something like 'fuel pollution system faulty'. I pulled over as soon as I could and consulted my manual. It suggested I should take the car to the garage as soon as possible.
