Dodgy Oil Pressure

[Lacko 0]

Hi all, sorry im not a massive poster! trying to get my knowledge up with my own 205 gti before i try and advise

 

Question is about my oil pressure. when idle hot/cold the oil pressure will fluctuate and kind of jolt slightly over an area.

 

I have a 1.6 91' phase 2.

 

anyway help would be appreciated!

Could be the senders a bit dodgy or the wires corroded giving a jumpy reading.

Worse case scenario is the bottom pulley is loose and the oil pump sprocket isn't being gripped, although yours is a later engine and the sprocket should be keyed to the crank.

I'd try a new oil pressure sender first see where that gets you
