Hope some of you folks can shed some light on this.
Defender Tdi 300 Just had oil/filter change. Now oil light stays on. Swapped oil sender unit with known working one. Oil light stays on just the same. Now I don't know if oil light was on before as I went to pick it up today as new purchase. Did all documentation etc then noticed oil light. It has a new filter, and golden oil. What you folk think? Low oil pressure? Cant be wiring as it lights up, at least that is my thought. Stu
