The battery is flat and/or not charging which is a common issue on these when the signal wire from the alternator to the battery controller fails.

At the moment you need a new ignition switch, a fairly common problem and easy to deal with.

Hi Everyone :

just to update , I left the headlight issue for the future when I will have enough time to fix them

let s resume :

1-/ opening car door using remote : issue solved by changing Ignition switch .
2-/ starter problem : new starter installed .
3-/AC not working : new compressor installed : AC work perfect .
5-/ full car maintenance was done : engine oil , fuel filter , spark plug , brake pads , AC filter , radiator cooling , only CVT multitronic oil change not done will be tackled separately later .

car issue now :

1-/ ABS problem : ESP light is on , ABS light off !!!

00526 - Brake Light Switch (F): 008 Implausible Signal

I think I need to change the brake switch .

I have used one : can someone help how to test if it s good or not ? Thanks , dealer does not have stock , I will try to find OEM new one ! my concern is that is the brake switch is faulty : why the ABS light is not on !? also if the Brake switch is faulty : whay I have the ESP , it should be more related to the ABS , no ?

yesterday took the car for a long drive : around 500 KM , issue noticed : engine keep reviving on 4000tr/min , car not shifting ! even took my feet from the gaz : RPM stay blocked on the 4000 tr/min and engine noise coming and car keep in the same gear ! diag : Engine , Gearbox : no error only the related to ABS found in engine section
18061/P1653/005715 - Please check DTC Memory of ABS Controller

I am suspecting the throttle body need some cleaning ! it feel like there is no synchronization between the engine and the gearbox
I tried a kick down : I am in the 5 th gear and kick down when it come to 5000 tr/min and it change to 6 th gear and despite my feet still down on the GAZ pedal , the rpm go s to 4000 tr/min and I have to push again to get a new kick down for 6th to 7 th gear ! no continuous kick down !

something wrong : or is it the car power train management not behaving normal : reduced power due to ESP light on !

ur help will be very appreciated

regards

Just replace the brake light switch as it does more than put the brake lights on this should solve the ABS issue.
