XSeries-forum

Over the last few weeks or so when starting the X5 I've had the message 'stop engine low oil pressure' and I have always switched off then back on again and all is OK.
Yesterday I thought that I had better check the oil level.. I am ashamed to say that I haven't done that for a long time and it was more apparent when I had to put 2 liters of oil in to get to the right level..
Lesson learnt. Check regularly.
Diffs next.

At least you caught it

My E53 used to give the same warning but in that case it was a bad sensor - it failed when the car was less than a week old! Had two more go in the first 6 months then it was fine until sold 6 years later.
