Why would you seek warrantee on a part you have no concept of problems on?

I would presume all aspects of life are a little more expensive due to such logic and the acceptance of some retailers to just go along. If you actually have a problem with the part it should be warranteed. I consider presenting it as failed with no such info, as petty theft.

Besides that an OVP on a 95 E320 can cause a no start, but would be about impossible to cause a misfire. The device is a power supply. The control units that need it work or don't when they don't get power. The early cars didn't need the electronics to run so a bad OVP could cause a running problem, not so with your car.

More likely, are the coils or coil to plug connectors. Those connectors are cheap enough to just replace all three of them (one to each of three coils).
