i have a problem with 2 coils..i must change it but some one tell me if you change coils you must change all is it true ? i think change only 2.. thax..

 

and when the check engine light come on VDCoff and SLIP light comes on same time is it normal ?

 

in english please

 

Dude he is from Cyprus.......do you even have a clue were that is.If the diagnostic test shows that only 2 coils are needed just replace those 2 coils.

 

you may want to try moving the 2 coils that you suspect are bad to other cylinders and seeing if the check engine light follows the coils to those locations. If so, yes, you can just change the 2 bad ones. However, it would pay to check the resistance on all of them, just to make sure the other 4 are perfectly in spec and not also on their way out

the VDC/Slip and Check engine lights can come on at the same time, but it depends what the code is

 

i change 2 coils and its ok now thanks for help
