2010 D4D - which circumstances trigger the OIL MAINT warning?

[dieseldane]

Hi all,

On my 2010 D4D the "oil maint." light message keeps popping up after driving for 15 minutes or so. Car was recently serviced, oil level is good but and no amount of resetting the oil maintenance warning will get rid of the warning. It is not there when I start the engine cold, so my suspicion is that it might be an oil level that's too high?

So I'm wondering - apart from the service intervals, which other circumstances trigger the "OIL MAINT" warning light?

thanks in advance

I was going to say doesn't the oil level being too high do this for the 1.4 - & this is an engine that is sometimes known to dump diesel into the oil via the DPF.

Thanks. That was something I was afraid of but didn't really want to think about.

In petrol engines there's a trick to check for petrol in the oil (hold the dipstick in a lighter if I recall correctly), are there any such checks for diesel?

By the way, the car only does 95% very long (400+ miles) motorway runs, so the DPF has plenty of opportunities to regenerate...
