My car is in the garage for the third time in about 4 weeks.
First time, the car was very jerky to drive - they changed the coil pack and said all was fixed. I collected the car the next morning and after about 10 miles it started again so back in.
Next, they put the old coil pack back in, did an ECU update, fitted a new O2 sensor and EGR valve.
All seemed fine until the engine management light came on last friday. Fault codes point to O2 sensor again, maybe post-cat this time.
I was told by someone if a car keeps going wrong on a similar thing, you can claim a new car as they are obviously not fixing it; is there any truth to this??
