They gave me the code

Is this a fault code?

Yea I believe so
Customer: replied 12 days ago.
To do with the ecu

The standard fault codes start with the letter P/B/U followed by 4-5 numbers. There is no information relating to that code, this can happen when using cheap code readers.

Do you have any warning lights/messages on the dashboard?

P0470 - Exhaust pressure sensor a circuit

This code is for the exhaust pressure sensor which looks like the one in the picture I have attached.

That’s what I thought but Halfords done a check and said it’s the Ecu which is faulty and that I need to see specialist in electrics ie Mercedes ?

Did halfords actually check the wiring to the sensor? There should be 5v power, ground and a signal which should change with rpm. If they have done their checks and there is a fault on the signal wire then the ECU must be repaired/replaced. Which will be easily £1200+ at a main dealer, an independant garage will be considerably cheaper, probably around £500.

There is a lot of online companies that can repair ECU faults, just type "ecu repairs" in google and there's a whole list of online companies. Repair will obviously be cheaper than replacement, depending on the fault.
