Hi everyone,
recently my 2018 Seat Leon ST300 Cupra Performance started to have this rubbery-ish vibration under full throttle acceleration (just when haldex kicks in).
Vibration it self is coming from the back of the car and continues to the front.
I replaced Hardy in the rear and no vibration appeared for a 100 to 200 km. After another 500 km the vibration suddenly came back.
Recently I gave the car a short yet intesive driving (launch control included) and after cool down drive home on a highway the car was vibrating as hell while cruising 130km/h. After couple minutes the car was suddenly ok
PS: Wheels arent bent, tyres are new, 108xxx km on the clock & all looked okay while being on a lift
Has anybody experienced something similar?
Thank you in advance for any tips and answers!
