Hope there is someone out there who can help me!!! to give a quick history, i seen that my p/s fluid was low and took it to a local garage ( i am english and living in france) i was getting the normal groan from the power steering which I thought was from the p/s fluid being low. When entering the garage I asked if they had the fluid needed (mineral p/s fluid green) to which he started pouring atf fluid red in it. after manipulating the wheel, the noise went and was able to drive another 10 miles until the noise came back, At this point i have no visable leakage spot under the car but now I have a totally ruptured steering rack with fluid pouring everywhere. After the mechanic informed me a new steering rack is needed, searching on the internet for the part is like trying to find rocking horse poop. so what I need to know is... The part number Audi has given me for the rack on my vehicle is 8H2422052D, I have called many motor factor companies and they ask me if my rack has a speed sensor on or not? which audi cant even tell me. All the car parts that sellers are saying to me is the part 8E2422052D and that this is the part for my car but audi are telling me the the H in the part number means cabriolet and the E in the other part number is just for the regular A4. Can someone tell me if the 8E part number can be used on my vehicle... I am so confused!!! Thanks in advance and if any more info is needed, please let me know!!
