Hi,
My S8 is due for new spark plugs. The engine is standard, except for an ECU tune/REMAP.
Which plugs are best to use?
Furthermore, I keep getting these annoying codes after about 150-200 km: P0171 & P0174
Changed the fuel filter, that didn't help. Engine idle's rough when cold.
Would be very grateful for a some advice.
