c5 2litre hdi 240k

Car runs perfect and just what ive come to expect from a c5. Any way got a daft niggle with this one once a week the car puts the light on and goes into limp mode so plug it in and get the following

" Micro dot power drop out"

Go to clear it and it says its permanent and cant be cleared so unplug the scanner and hey presto the light is of and full power back. so plug it straight back in and it now says no codes present and car runs fine for another week

 

Being doing diagnostics for a couple of years now so ive got a good grasp espically with c5s but struggling with this one

 

Any ideas

you got the p-code mate.

No code numbers present at all just says micro dot power drop out. Have been told that its a possible injector ecu software update needed. Any thoughts.

Its not a problem as such because the cars come in once a week to get checked over so we just plug it in. its more curiosity and the need to no
