My 5th company car was a Citroën Xantia 1.8 and my first car that really had temperament. A company car that requires oil filling...

When it lacked oil, not only did oil lamp illuminate, but all the bulbs in the dashboard lit up. In addition, it had an annoying orange lamp that was on when there was no more washer fluid. Not a while before, but exactly the moment it was empty. This lamp also had the habit of continuing to light even though it had been refilled. After several calls to the workshop I announced that I would not see it light up anymore. I discovered later that they had cut wire.

This was the 3rd Citroen I had, first, last and only one.
