Hello everybody, Long story short, the steering box of my A4 2013 sedan black edition right hand 1.8 tfsi, drive makes a noise when I turn the steering wheel. I want to buy another steering box to take it with the car to a service to have it changed. The problem is that I don't know what OEM number/serial to look for. someone who can help me with the information. I tried to look for the oem number of the part (assembly) by myself but it gives me a whole list, see the picture attached to the post. I found the part from an identical but diesel car, but I don't know if it fits mine (petrol) i can provide VIN number Thank you for any information.
