Hi Everyone.
Please can people advise me how long and how fast am I able to drive in Limp Home Mode. Will it damage the car. It was missfiring and now has gone into LHM. Can I reset it by disconnecting the car battery?
The car is a BMW Alpina V8 4.6 1998 model. Everything else works.
Thanking you in advance.

BTW where is the OBD port located on these cars?
