Hello all,

 

I've a galaxy 2013 2.2 PSA engine.

Have had the car 3 years with no major issues during that time - DPF was removed shortly after purchase, Catalyst replaced 5 months ago after flexi joint and mount failed.

 

Driving along at normal in town speed, and with no prior indication, the car lost all power, no dash warnings, noises etc.

 

Now the car starts up from cold, fires up perfectly first press of button, revs up like normal, and can be held at high revs for 30 seconds or so, or driven approx 400m.

Then it loses all power again, revs fall to 1k rpm and will not increase, it will sit and idle sounding perfect, but any attempt to accelerate it simply stutters and fluctuates around 1k rpm. It will happily sit idling for as long as I want, shows no sign of cutting out, but simply will not accelerate.

 

Once turned off, the car will NOT restart again, pressing the button everything lights up on dash as normal, but the starter doesn't try to engage, nothing.

Left for 40 minutes to an hour, the car will fire up perfectly, and then follow the same pattern as above.

 

Garage have looked and tried changing sensors and removing various pipes, can find nothing mechanically wrong - say its electrical.

Auto-electrician has checked electrical side and says all is in order - it must be a software issue.

Neither could find any fault codes to narrow the issue down.

 

I've bought an adaptor and downloaded Forscan which is showing the following;

 

U0126:00-8A

B1B57:11-2F

B1B58:11-2F

 

None of these would cause the above issue I'm sure (parking sensors have never been operational)

Any clues on where to start looking, or what the cause may be??

I wouldn't be too quick to dismiss this. If I understand the dtc correctly it is referring to the steering angle. This can put the vehicle in to limp mode.

Have a read of this Mondeo with slightly similar issues:

Yes, I know its not exactly the same but take on board the list of problems and what the fix was at the end.

It is a bit of a long shot, but my 1st guess was an alternator problem, causing odd voltage dips, surges or ripple on the 12v supply to all modules. A neighbor had an intermittent problem where the engine would start, but sometimes not obey the throttle at all, just sat at idle. That was fixed by changing the alternator.

The park sensors are quite likely to be easily upset by odd voltages. The ECU software can also get upset by them.

I would expect to see more error messages though. Have you tried reading DTCs in the period where it will not start. It seems like the 40min wait could be for the ECU to fully shut down, and clear some codes or an internal condition that is preventing starting.

Also check all fuses, esp ECU ones, in the engine bay fuse box. Some of these supply standby power to the ECU, etc.

 

Have you sorted your problem? I experience exactly the same problem on my 2013 ford S max 2.2 200bhp

Andy probably still has the fault, it's only been a year since he was last here.

Might be a good idea to start a new thread with your problem.

Hi everyone. 

Coming up with an update and the way i fixed the problem.

I had my dpf gutted in the past and been to a so called tuner to do remap. He hasnt done a very good job and the worst part he has hidden all errors that would involve exhaust gas temperatures.

Long story short. The 4th exhaust temp sensor (last one after dpf)  failed and would put the car in limp mode...but as i specified above. So ecu kicks in with the protection but would not show the error code saying the sensor failed as its been hidden previously by the tuner.....so i did written the original file back on the car...found the error code saying sensor failed. Changed the sensor and now the car revs normally amd drives normally. I then went to a proper tuner to have a profesional remap and happy days. (Also to specify...the remap i had done first would show dpf load and dpf soot 30% raising...which should be 0% with a proper dpf of remap...which turns the fisrst one was a failed remap...so be aware if you choose to gut your dpf ..make sure you do a remap with profeasionals.

 

Hope this will help other fellow Forders 🙂
