Moin people, My mother has a problem with her Fiat Doblo (1,4l petrol engine, 2005). When the engine comes to temperature and then you have high speed (as for example when crossing the country at 80km/h upwards) the yellow engine control light starts to light up (according to the manual, it stands for an error/problem with the injection). Her screwdriver first meant that it is due to a cracked cracker, so bought a new crusher with cat and lambda probe and bought (the prices for this are su However, the problem was still there, then spark plugs, ignition cables and ignition coils were replaced. Allegedly there were error code for the ignition in the error memory. However, the problem still exists. That the problem with the indicator light is connected with the engine speed I found myself during a test drive ( unfortunately I do not live nearby). I therefore think that the problem is probably actually what with the injection system (mixing preparation) Are there typical errors or do you have to do a “traditional” troubleshooting, where you have to work slowly from the air inlet to the air filter to the injection system, as well as from the tank, over fuel filter to injection system and possibly even further over valves to the cylinder, through??? I hope here can help me jmd., my mother has put far too much coal into the cucumber, without which the error was removed and financially standing she is not well there as a pensioner. Greetz
