    Why does my 2009 Ford Mondeo keep going into limp mode?

    Ford Ford Advice Ford Mondeo Ford Mondeo Advice Ford Mondeo 2009

    My 2009 Ford Mondeo 1.8-litre diesel goes into limp mode. I've changed the fuel filter housing and had the injectors checked. She will go fine for a few days then go back into limp mode. The anti-skid button comes on sometimes before it happens. What could be the problem?

    It sounds like the stability-control program is throwing up random fault codes that are telling the on-board computer that something’s wrong with this very important piece of safety technology. At that point, the protocol could be to send the car into limp-home mode to avoid having a faulty stability-control system create any problems that could cause a crash. But who knows, because there are literally hundreds of systems on a modern car that could cause this sort of malfunction.

    Because the ESP light only comes on sometimes before the limp-home condition occurs, perhaps the two are related but not reliant on each other. While the engine limp-home mode is usually associated with a problem under the bonnet, the ESP light is more likely to be triggered by a problem with the braking or throttle-by-wire system. Certainly, the latter could also trigger a limp-home response from the engine.

    Have the car scanned by a workshop and see what fault codes pop their heads up. That will save a lot of time and money compared with changing components until you find the one at fault.
