Hello everyone. I have a problem were my 2007 s max 2.0 tdci is randomly cutting out. I have scanned the forums and am no further forward hence the post. 

There doesn’t seem to be a particular pattern or type of situation it happens in. The car has “stalled” at 70 on dual carriageway and has done it at low speed and revs as well. The car will sometimes go for a long distance drive with no issue and other will cut out a few times in the space of a few miles. 

When this initially happened I had computer read which stated An egr valve min max stop performance fault. As such I have had a new egr fitted and also had a new fuel filter fitted as that was a common theme. 

When the car stalls sometimes it can be restarted by dipping clutch and switching ignition on and off whilst in motion. Other times the ignition will just turn over and it needs to come to a stop and have a few goes at turning over before starting again. The car has done 116000 miles but is in otherwise good nick. Obviously the lady of the house is not amused with the cars behaviour but I don’t want to buy a new one particularly after paying for new egr. When it broke down after egr replacement did another computer read and no codes were showing. 

When the car cuts out we get a yellow fuel pump warning light and the yellow stability light as well. 

Any advice or suggestions gratefully accepted

thanks 

Hi, sorry to start up an old topic again. Did you ever get this problem resolved? I am having exactly the same issue at the moment. Any help would be appreciated. Has anyone else had this happen? I have a 2010 2.0l diesel S-Max

 

thanks

Hi. I am having the same issue as well. My car is a 2010 S-Max Titanium 2.0 tdci. Having problems starting whether engine is hot or cold for the past year but the cutting out during driving problem has only just started in the last week. As soon as the engine cuts out the ESP yellow warning light shows on the dashboard and the rev counter drops to zero despite the car being in gear and turning the engine. I have replaced the MAP Absolute Manifold Pressure sensor, Crankshaft Position sensor and the Camshaft position sensor. Have any of you resolved the issue yet?

Thanks.

The rev counter is no longer a mechanically driven instrument with a flexible steel drive cable. In actual fact they are an electrically powered tachometer. Once the engine cuts out there is no longer any signal from the ECM to operate the Tacho, which we all still commonly refer to as the rev counter.
