My 2004 TD4 is a troublesome car. I bought it from Craddocks 6 months ago and it caused them trouble throughout the warranty period. Recently when going uphill the EML will come on and reduced power. Stop, restart and it clears until the next hill. When it's not on you can press hard with no problem. I've disconnected and reconnected the MAF sensor and there is no effect. Recent Fuel Pump Reg, Alternator, Battery and full service plus Craddocks spent two weeks trying every last thing. ( I fell out with them ?), No fault codes. Please does someone have the answer or any suggestions, other than a can of petrol and box of matches. This car could end my love of Landies.
