I have a 2007 Peugeot 307, I noticed since 3 weeks back after returning from major engine repair work that the steering becomes occasionally had to turn. One I experience this abnormality, I require extra effort to turn the steering and all of a sudden afterwards it steering returns to power assisted mode. Note the fluid level is on guage and no leakage. What could be the problem?
