E class convertible ECU

[Jasandjules]

Well, the car complained it had an ad blue issue. STAR told us it needed a new ad blue pump which was fitted. Then it was fine for about 30 miles and the ad blue issue came back on. Back to garage and checked and it says need new pump.. Another pump fitted (assumed the other was defective) - car still says ad blue pump issue..

Now garage thinks the ECU needs checking/fixing as it is wrongly complaining about the Ad Blue pump. Is there anyone local to Sudbury who can look at ECUs does anyone know?

I think there is a similar thread in engine and drivetrain section if yours is the same engine.
