Hi everyone,

I'm about to look at a 1976 W115 240D 3.0. It's got a glow plug problem so I wanted to order a set so I can do some tinkering.

I don't yet have access to the VIN or a confirmation on which type of glow plugs the car would likely require. Can anybody tell me what are the likely ones it'll be using?

A part number would be excellent too if that's possible.

Also, would this model have a glow plug relay?

The car was built in 1975 but registered in 1976 if that makes any difference - and is badged 240D 3.0 rather than 300D.

Thanks!
