Having a couple of issues with my R26. driving home last night and just around the corner from home the oil pressure warning flashed up and the went out again, did it once more has I pulled onto the drive. Had a look and it was a little low on oil so filled it up, started it up and it all seemed fine. Once again this morning on the way to work once the car had been driven 10 miles or so and up to temperature the light and message came up. Hoping it's just a sensor as in my mind if it was anything really serious it would always be showing low oil pressure so I've ordered one which should arrive today. Has anyone had a similar issue at all? Also where abouts on the R26 is the oil pressure sensor located?
