Gooday everybody I am a newcomer and have a couple of questions the first relates to having to start my Landrover TD5 Defender 2001/2002 model with aerostart being sprayed into the snorkel because it does not start regularly otherwise, the auotelectrician seemd to reckon that there was oil in the wiring loom could this be the problem as the motor mechanic reckons that it is the injectors and also makes mention of the oil in the wiring loom could it be both or is it it just one of the above mentioned. The other problem is that the speedo died on me the other day it fluctuated before it died what could be the problem and what would be the best way to fault find for the problem. What I did forget to mention in the first part is that the light that indicates an engine fault in the engine goes on and off on the dashboard does this have anything to do with the first question. Looking forward to some honest advice.
