4ws weird intermittent

[c_doughty1]

Ok I've recently had my 4ws steering fixed thanks to @confused but now it's having a tantrum....it's working most of the time but it's throwing an error code that I can't find.
The 4ws light flashes 7 times slowly which does a repeated cycle of that about 6 or 7 times then flashes I would say 12 to 15 times but crazy fast.
Also at the same time I now have error code 12 for egr again which both have come at the exact same time.
Any advice / help would be greatly appreciated.
If I turn car off an on again the 4ws will start working again so I'm confused.

Could it be an ignition fault? Or intermittent power to the 4WS ECU?

Temporary Codes:
70 - Ignition is turned from OFF to ON while driving.
71 - The car is driven aggressively with four people in the car, or the rear wheel is blocked by the kerb.
73 - The engine is started while quick-charging the battery
74 - Driving the car with the parking brake ON

The code is 7 though? What would 70 be? Flash wise

[Merlin]

Code 70 = 7 long flashes.

The 4ws light flashes 7 times slowly

Right ok that makes sense, so how do I fix it?

[c_doughty1]

Because I don't turn my ignition off then on whilst I'm driving that would be rather dangerous

[Merlin]

Are there any other symptoms?

[Dbo]

When mine did this... if it resets on ignition off and then works again without doing the fuse pull for ecu reset...
then on mine it was a bad earth....
where the 4ws ecu in boot earths to body... i scrapped some paint away and fitted a nut and bolt through another hole and did up real tight.... it fixed mine....

Ok so you think maybe an earthing issue? I'll take the rear seat out n have a look then

No none
