Fuel Rail/System Pressure P0087 & Cylinder Misfire HELP
 

Hello Guys, I have a S5 2010 V8. It all started with Cylinder 5&6 misfiring. So I changed the coil packs. After this I turned on the engine and it took a few cranks before it started. Now it shows Cyl 5&6 misfire, Cylinder Disabling P130A, and Rail/System Pressure P0087 . Engine is very difficult to start and when it starts it runs very rough. I think Cyl 5&6 and disabled. I cleared the faults and the same come back with the same simptons. Any help will be greatly appreciated.

I am not familiar with your problem. I might suggest if you are on FaceBook hit up the Audi A5/S5/RS5 Owners Group. I have found I get quicker responses from that group. Very knowledgeable folks..... good luck!!
