Oil pressure low Warning!
I have recently changed the sump on my 2002 147 2.0l twinspark as the old one was cracked after refitting the new sump the engine oil pressure low warning has come on before sump change never had the warning been driving the car for 3 months.
When i start the car there is no bad tapping noise coming from engine as it is cold is dose sound like a diesel but this was no different then before sump change.
Left it for a day to see if different just tried it and no change did notice tho that when taking the oil filler capon top of the engine off there is air been pumped out.
Can anyone help me i don't really want to drive it to my local garage to get the oil pressure tested if there is not any oil been pumped around the engine block.
I have searched this forum and it seem the oil pressure sensor it a common fault thinking of changing it to be on the safe side.
