Full Version: Engine Malfunction
Ford Owners Club - Ford Forums > Ford Models > Ford S-Max Club
Just joined the club as I am having more trouble with my 2006 Smax 2.0 TDCI and was after some advice as I am not technically minded. Having been through the problems with the brakes and alarm all was well until the engine light came on a few weeks ago. Diagnostic test at the garange said it needed a new ERG(filter and solenoid?) which was fitted and I was told the problem was solved. However, first time I took the car out after about twenty miles the car started jumping as if it was running out of fuel and then suffered from a loss of power. The engine malfunction light came on and whilst i got the car home i was restricted to 2500 rpm. When i turned the car off and on again the malfunction sign had gone and all seemed well until I hit 2500rpm when the sign reappeared adn power was lost. I have taken the car back to the garage nad they say its nothing to do with the ERG issue and diagnostic doesn't show a problem. They also say they have never seen or heard of this issue before.

I have read online that 2.00 tdci have seen these sort of problems before but cant find anything on an SMax. Has anyone else had a similar problem or know whether a ford techncial service bulletin has been issued as the garage are saying it could take hours to find the issue and they want to charge 85 an hour.

Any help wuld be appreciated. Thanks
your car is going into 'limp home mode' because of a problem,if the eml came on there will be a fault code stored in the ecu, are the garage using the right scanner as the later ones (OBD2) will not deal with pre 2004 diesel engines.
The engine is a 20066 so the garage should have the right scanner, they are also a ford main dealer so i would be suprised if it wasnt. They have told me that there are no fault codes registered.
Problem solved. Apparently the new valve they fitted was faulty!
