Hi all, hope a few of you can point me in the right direction Lummox take a look, friend is having problems with a Fabia 2002 bby engine intermittently a fault will log

17574 - Long Term Fuel Trim Additive Air; Bank 1; Range 2: System too Rich

P1166

The fault will clear but will come back on after a few miles previosly other garages have taken a look

new lambda probe front, coolant temp sensor, charcole cannister solonoid, EGR valve, fuel filter and throttle body clean.

Valve timming is correct.
