I am going to change my o2 sensor on my 1988 560sl
Do I have to reset anything ?
In the shop cd it says something about a indicator control module # n441/1
Where is that ?
It had to be reset once because its got 78,000miles
Any help would be appreciated greatly
Is there any trick way to get out one rusted sensor without destroyng
the exhaust system?
