Dear Forum members, I am new here and have the following burning question, hope anybody can assist. I searched if this topic was discussed bfore and could not find. I own a Audi Q5, 3.0L automatic 08/2014. The car now passed 100 000 KM's and is always AUDI maintained. I also have a rear view parking camera system, original Audi. About 10 000 KMs ago I purchased the OBD11 connector and upgraded my car with the Drive Select, I do not have a button in the dash for it. Worked perfect and added a lot of extra value. Last week I had a Westphalia detachable towbar system installed and I noticed the Drive Select upgrade is gone and new features were installed to accomodate reverse parking with towbar. New beep sound as well when the towbar is connected.

My question as follows, I like to reinstall the Drive Select Feature from OBD11, will this erase the Towbar Software feature implemented by Audi?

regards Alex
