Hi everyone, I have recently bought a MY2014 C1 MK2. Iv only had it a day and all the warning lights have come on. The fault code is P0141. There is a technical service bulletin for the fault which is to replace the engine ECU and the oxygen sensor. Both these parts come to over £1700. It turns out that if the fault occurs on an Aygo, Toyota can do a software update to the engine ECU and just fit the new modified sensor (obviously much cheaper but unfortunately PSA can't do updates). Has anyone here had the PSA ecu updated? I have spoken to a Toyota main dealer who do Citroen, Toyota and Peugeot but the PSA vehicles will not update on Toyota systems. I'm also wondering if anyone here has fitted an engine ECU from an Aygo (2014 on) onto either a C1 or an 108. Fingers crossed you guys may of had some experience of this.

Thanks

Early lambdas on Mk2 were prone to failure, nobody ever changes the ECU, and I dont ever recall anyone having a update.

Change the sensors and reset codes and drive away is the norm.

As for why the Toyota system cant update a C1, that must be purely as someone programmed it not too, the hardware is identical.

Thanks for the reply, the new oxygen sensors have a shielding in them to prevent the fault re occuring. Unfortunately the new sensors are not backwards compatible with the old engine ECU.

I have found a replacement oxygen sensor that it compatible with the old ECU but my concern is the fault will reoccur without fitting the known modified part.

Just get an aftermarket O2 sensor, the issue seems to just 'go away'. It really isn't a 'thing' in the C1 scene.
