If you get the message "Oil Pressure Low - Stop Engine" error message every morning or when the car has been sat all day, there is a possibility the Oil Seal on the pickup pipe inside the sump has lost its flexibility. This lets oil drain back into the sump out of the oil pump.

To replace the seal the sump has to be removed, which on the Insignia requires the gearbox to be splt from the engine to get to 2 of the bolts holding the sump on.
Unless you are brave and extremely careful
I cannot be held responsible if you try this and damage your DMF
It is possible to notch out the gearbox bell casing to provide access to the 2 bolts, but there is very little room for error when drilling/grinding the case between the DMF and the casing. You can see where the notches were made on my car.
It is a case of removing all the bolts and dropping the sump off. (4x4 has another set of difficult bolts as the transfer box is in the way as well)
Here you can see the oil seal in place.
It is then a case of cleaning off the old gasket from the sump, applying more and carefully re-fitting the sump, noting that the inaccessible bolts are tricky. On my car we held them loosely in place with the liquid gasket and started them off first, because if they fall out you have to start again in re-fitting it.
