Sam555 Posted August 2, 2022 Share Posted August 2, 2022 I have a 2014 Focus 1.6tdci. Over the last couple of weeks it had a sudden loss of power (similar to what limp mode feels like) on several occasions, lasting roughly 5 minutes on each occasion. There is no engine warning light coming on and I have found no fault codes with my £9.99 eBay diagnostic machine. Roughly when this problem started the engine fan started running regularly after the engine was switched off which is unusual for this car. I intend to take it to the garage but it would be good to be armed with a bit of knowledge before I go. Any information or help will be very much appreciated.

TomsFocus Posted August 3, 2022 Share Posted August 3, 2022 Usually it's the DPF failing to regenerate that causes the fan to run on after engine shut-off. Though due to the extreme heat we're having currently, it could also be caused by high coolant temps. I assume the coolant temp gauge isn't reading too high and you've checked the coolant level? If you have no warning lights, it probably just needs a good run to get the DPF fully regenerated. Forscan is better than a generic eBay tool or, in general, a garage tool. Costs about £20 for the ELM adapter and the program is free for a laptop. Quote Link to comment Share on other sites More sharing options...
