hey guys

I got a focus 1.8 TDDI estate recently, and the oil light keeps flashing... seems to be worse when accellerating. Ive been told it may be a pressure switch, but after looking in the engine, i came across what looks like fresh oil... ive enclosed some pics of the oil patches, and the area where i noticed it.

Any ideas would be appreciated...

Silly question, but you have checked you are filled up to the top with oil?

[Wayney]

yeah, levels are fine, and not noticed it go down at all

[dezwez]

i would do the pressure switch, and see if it fixs it
frist

Is oil around that joint normal though?

[ChrisH]

Oil can seep all over the place. I would agree, do the pressure switch, and clean this area. Check again after a drive, and see if there is any oil there. Do you get oil drips on the floor whilst parked??

[Wayney]

Not noticed any drips yet. Nor any signs of the oil level going down... Is the switch easy to find/do for a total novice? My mechanic will do it pretty cheap otherwise

[dezwez]

let your mechanic do it if its cheap if it go,s worng it down to him to sort
should be easy to do

Give that joint a thorough clean, and then keep a close eye on it.
If fresh oil appears, you have the culprit.
If no fresh oil appears, then what you see now is just a slow accumulated build up over time.

Thanks for the replies guys! I'll give the engine a clean monday and get the oil pressure switch replaced, then keep a close eye on the dirty area and see if that stays clean I've only had it a week, and already some faults, so just a little paranoid i guess lol

[Andy H Dibley]

It'll be fine!

If the levels are all ok and there is oil sloshing around, you're not about to seize up, which is the important thing!

Ok, got the oil pressure switch fitted today (pics added), however after 10 mins of driving the light came back on as normal.... What would be the next step? or what could it be? theres still no obvious sign of any actual leak, i dont see its a wire/lose connection since it only starts when the engine is warmed up, and linked to accelleration etc

sorry for the poor quality, they were taken on my phone

I'm no expert but could disconecting the battery help ?

failing that it may be a a add a short or a faulty bulb on the dash.

[Wayney]

i thought/bulb or wire, but surely it would then happen all the time? not only when the engine is hot

Failing oil pump?
