Ongoing EPC and check engine light

[alexperth]

hi all,
I am sorry if my post is not in the right category.
I have a serious problem.
I own a vw polo ,only 47000km
My car has been to Vw repair centre in perth 8 times during theast 6 times.
Basically, car starts vibrating and loses power and EPC and CEL is on.
Last time VW had my car for 3 weeks. I picked it up yesterday and same thing happened this morning. EPC and CEL IS BACK. I waited 6 hours and started the car. EPC is gone , car has more power when i accelerate

They have been telling me , cylinder 4 misfire, they changed the sparks, coil pack, lead,new battery, cleaned the carbon but problem is still there.
I just cant understand why they cant find the issue.can anyone help me on this.
Thanks

Depending what polo you have it might be the same engine.
