I believe the learning process is not a protracted period of time. Say 600 to 1000 miles. My egg shaped wheel feeling only happens under low load kick downs never if I'm flooring the throttle. When i starts i can hold it there as long as i like or the road permits.
The dealer has over the last two days checked a bunch of things and replace the air filter and the main brain relay. It's better but still noticeable.
We just want it fixed and get back to beautiful purrrrrring motoring.
