Gavin78 Posted January 30, 2019 Share Posted January 30, 2019 I know this has been covered in other threads but having thrown a decent chunk of cash at the car, I am still getting the same problem. So, The main issue is that at motorway speeds the car will some times lose power...it will maintain speed but will barely accelerate even if you change down a couple of gears. I have to shut the car off and immediately restart then the problem goes away....usually on the move. As part of the 'fix' I have had the turbo refurbed, cleaned the DPF and replaced the EGR. In addition it has also had a full service including new diesel filter and after finding 'black death' around cyl no 3, new injector seals were also included. After all this...still the same problem! Any ideas? I have thought maybe diesel pump or maybe even a blocked cat/exhaust but I figured that would throw at least 1 code but so far we see nothing. Anyone had a similar problem? Thanks for your help. Quote Link to comment Share on other sites More sharing options...
guy woodbridge Posted January 30, 2019 Share Posted January 30, 2019 Ive had similar (on a different car) I changed the camshaft sensor which sorted it out at the time. Also might be worth checking if this is a chain or cam belt. That can sometimes cause isues like you mention. Quote Link to comment Share on other sites More sharing options...
isetta Posted January 30, 2019 Share Posted January 30, 2019 1.6tdci is belt driven. well, sort of, if you have the newer 8 valve single cam version it is belt driven. If you have the older 16 valve twin cam version it has a belt from the crankshaft up to one camshaft, then it has a chain from one camshaft to the other camshaft Quote Link to comment Share on other sites More sharing options...
Gavin78 Posted January 31, 2019 Author Share Posted January 31, 2019 SO, the cambelt can cause an intermittent issue like that? Did the camshaft sensor failure you experienced not throw up any codes? Quote Link to comment Share on other sites More sharing options...
Gavin78 Posted February 17, 2019 Author Share Posted February 17, 2019 Update - it was the ECU! Apparently it is a somewhat common fault...the EGR controller in the ECU fries likely due to the failure of the EGR itself. The strange thing is that it rarely throws a code and you need to find someone with Ford IDS to interrogate the ECU properly. I took advantage of having the ECU repaired to have it mapped as well...well worth the effort! 2 Quote Link to comment Share on other sites More sharing options...
TDCiST Posted February 17, 2019 Share Posted February 17, 2019 I had a similar problem on my old 1.6 focus... but got shot of it for a new shiny one! Maybe this was the issue too as they never found the reason. Slight inclines at motorway speeds could be comical at times! Quote Link to comment Share on other sites More sharing options...

Does the chain between cams ever need replacing? I'm very high mileage, 165,000. What effect would it have if it snapped? Quote Link to comment Share on other sites More sharing options...
isetta Posted February 18, 2019 Share Posted February 18, 2019 I don't know if Ford say the chain ever needs replacing after a certain interval. I don't know if you would get warning signs first (eg rattle etc). If it snaps it will be same result as timing belt going, except only 8 valves will be at risk instead of all 16 (as the first camshaft will still be in sync with the pistons from the belt). 1 Quote Link to comment Share on other sites More sharing options...
guy woodbridge Posted February 19, 2019 Share Posted February 19, 2019 Glad you got it sorted out. To reply. My understanding of it is, yes a stretched belt or chain can start causing intermitent engine power loss. Yes there were codes for crankshaft position sensor and off the top of my head there was one or two for something else to do with engine timing. This would be prior to total faulire though lol!
