My HawkEye reads,
Fault 4074,
Inlet Valve Right-Hand Rear. ( Power Amp. with Short to Uvent ).
It stores faults 4075, 4075 etc, for the Inlet Valve for each corner of the car.( So 4 faults each time ).
Its listed as an " HISTORICAL " fault.
These faults are logged after the 3 amigo,s flash up.
The lights, in my case, are always reset when the ingnition is switched off and then on again.
In the 3 years/30,000 miles I,ve had the car, the 3 amigo,s has flashed up about 5 times.
I,m fairly sure its due to a common fault in the shuttle valve switch.
