I think i may have an ECU problem on my 2007 407SW Peugeot.

Customer Question

Hi, i think i may have an ECU problem on my 2007 407SW Peugeot. I currently have cold start, coolant error and an emission error message on my dashboard. I am not sure if it s worth getting this fixed. Was planning on speaking to a mechanic tomorrow, but thought i would ask here first on whether this is a big or small job.

Forgot to add when the cooler light comes and i then get the stop light, after 1 minute on the car goes into limp mode. When i had the scan done the guy said the engine was fine, but the sensor appeared to be the error.

Hello, I am Jose Sebastian. Your mechanic automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.

Dear customer, these problems are common in peugeots cars, when the sensor is defective, the problems with the emission light in cold happen, normally occurs when the car turns on, the coolant pass a bit to the chamber or its just that the exhaust has stored liquids due to the condensation, this could trigger a bad read in the exhaust system and turns on the indicator. But once the car is turned on and the engine’stemperature gets high, the waste is burned and the light turns off. But it is not something to bad, you have to not be worried.

Is there anything else I could do for you?
