Yesterday morning we left the Dordogne region of France to head for home and I had noticed for the previous couple of days there was a slight hesitation when gently accelerating with the engine cold. Shortly after leaving yesterday, the "clean fuel filter" message came up in the dash. It was accompanied by the same slight hesitation I had noticed previously, but other than that, all seemed ok.
I decided to press on, having acknowledged the warning message. I had filled the tank about three days previously, so didn't need a refill for another 400 miles or so and assumed I must have taken on some contaminated diesel and hoped it would be ok. Anyhow, I refilled later on and after starting, the message hasn't reappeared, the hesitation has cleared and I've done a further 525 miles with no problem.
Given that any dirt in the fuel wouldn't clear itself, I'm now wondering if there was water in the diesel I had taken on, which somehow partially clogs the filter, but eventually clears. There had been rain of biblical proportions in the region a few days before, so is it possible it might have got into the filling station storage tanks? Would water in the fuel filter cause this?
