c250td engine ecu reset

[Uberderv]

Hi all, is there any way to reset the engine ecu without the star diag? I can't get to a garage for diag and my mot is due so I need the light off to buy me a bit of time.

Thanks in advance.

The ECU automatically resets as long as errors are not live.

What is the actual fault symptom?

It's intermittent power loss, it will go into limp mode with the EPC light on for a short while then fix its self.
Have changed map, vac transducer, all o rings, filters etc....

.Could a bad earth do this because the auto window control seems to stop working around the same time?

I doubt hey are on the same earth point, but a poor power connection could well trigger a fault.
What about the Ign switch being faulty?

 

[Uberderv]

Not sure about the ign switch, I mot'd it yesterday everything was fine, fitted new bulbs in the main and side.

After the mot the epc lights on, power loss, auto windows don't work and my new chuffing sidelight bulbs are blown

The car failed on a minor point but I can't retest it with the light on.
