hello,
1987 190D NON turbo-
My AC quit working at the same time I started experiencing a rough idle.
(my tach has been broke for over a year)
I am pretty sure it is the OVP. If anyone has another opinion, I am open to listen.


I have looked for an OVP on Pelican Parts, but cant find one. I have looked at other sites (ebay, Amazon etc) and there seems to be a discrepancy as to whether the OVP has the same part number for a turbo and non turbo. Does anyone know the part number for a 1987 190D NON turbo 2.5?
If you have a used one, I am open to buying it.


Can I bypass the OVP to test?
Can I bypass the OVP permanently?
