derbyian1983 Posted March 2, 2014 Share Posted March 2, 2014 Hi all new to the forum! Recently Bought a 60 plate fiesta zetec s tdci (95bhp) and the cooling fan has a mind of its own..... Every few days! After a short journey it some times comes on for a min or so.....The engine isn't over heating and the air con isn't being used. After looking on Google it's pointing to the cooling fan relay or the dpf regenerating???? Has anybody else had this problem? I had it remapped a few weeks ago due to it being underpowered and poor fuel mpg, not sure if this could cause the dpf to regenerate more often with the extra power? Thanks in advance Quote Link to comment Share on other sites More sharing options...
tom_d Posted March 2, 2014 Share Posted March 2, 2014 hat could be the dpf regenerating. The fans staying on after is symptom of that. I've heard that some remaps could make it smoke more which could cause it needing to regen more Quote Link to comment Share on other sites More sharing options...
derbyian1983 Posted March 2, 2014 Author Share Posted March 2, 2014 It doesn't stay on long, a minute or so after the engine e is switched off. It doesn't smoke at all but has made a massive difference in power and mpg. Quote Link to comment Share on other sites More sharing options...
tom_d Posted March 2, 2014 Share Posted March 2, 2014 It could be smoking more, it would just be getting caught by the dpf, then making it regen more Quote Link to comment Share on other sites More sharing options...
Mike77 Posted March 2, 2014 Share Posted March 2, 2014 My fiesta does this with the fan, but mine doesn't have a DPF, sometimes after a short journey the fan will stay on for a few mins after switching off... Dunno why it does it, just does ? Quote Link to comment Share on other sites More sharing options...
K-Singh Posted March 2, 2014 Share Posted March 2, 2014 Mine has a dpf and does the same after a hard thrash, look at the instant consumption before turning the car off if its above 0.2g/hr it means a regen has just taken place Sent from my iPhone using Ford OC Quote Link to comment Share on other sites More sharing options...
derbyian1983 Posted March 2, 2014 Author Share Posted March 2, 2014 Sounds like it's just something they do then? Didn't notice it before having it remapped but only had it a couple of weeks then.

derbyian1983 Posted March 2, 2014 Author Share Posted March 2, 2014 Doesn't sound like anything to be worried about then! Was expecting either bad news or a large repair bill Sent from my GT-I9505 using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
