16056 - Oil pressure switch: Malfunction

[danncus]

In the summer I had the coil light come on and messages about start stop disabled. Every warmup.

On the carista it pointed to an oil pressure issue. After looking around here, I changes the front oil pressure sensor and it didn’t re occur.

The above code has now appeared (4 months later). Again at warmup.

Has anyone encountered this?

Thanks

I had this recently. Garage replaced both oil pressure switches and the fault remained.
Mine also only occurred when cold. I did the vcds test of the oil pressure changeover valve and it showed a fail.
Had that replaced by garage (£223 incl labour) and it's been fine since.
There is a thread regarding it all and a lot of analysis by @mmi
