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.

hello, i had a similar problem with the s5 4.2, i swapped the spark plugs, coils, injectors and no luck, i end up removing the valve cover and found the valve spring in 2 pieces. you can always check the fuel pressure 2.

Can we have changed the specs in the computer with a code reader, when releasing the ebrake. Is this possible ?
