I don't want to sound rude but over 48 hours, over 30 views and not even a sorry I don't know seems odd to me.
Please even if it's a I don't know but you could look here would be welcomed.
I am in Mexico and e36 is the first model sold here. The dealer said take it to an indipendent because they don't know this model. If the dealer doesn't know how to do it I sure am not taking it to some one else that has never seen this car.
