Oil pressure stop engine in red

[Damiene220]

Oil pressure stop engine in red comes on intermittently for a couple of seconds generally when first started as it seems upto now.
The car is a 66 plate e220d amg line with 60k on the clock.
Any thoughts as its quite disturbing and doesn't seem to effect performance and the car seems to be fine

Engine code OM65.....?

 

[markjay]

It could be a faulty oil pressure switch, or damaged wiring, but low oil pressure warning should never be ignored, so you should get the fault codes scanned with STAR.

As above never ignore .

This time of year could even be a damp connection.

 

[W1ghty]

Do you still have Mobilio recovery ?

There was another thread where this came up on a similar vintage E220d, but I don’t remember whether the person reporting the issue ever closed it out with what the resolution was.

Probably worth a search…

Engine code OM65.....?

I thought OM651 did not have any oil pressure sensor (or switch), just oil level. The early OM654 engines had some odd issue and gave false oil pressure alarms but I cannot remember what was the reason and how was it fixed. Still, as above, shouldn't be ignored.

ASAP

No code

No code

let's try 1950 or 2143cc ?

In summary and as per a lot of advice above, get it to a trusted Merc independent specialist ASAP and I recommend not driving it except to the garage.

The best case outcome is they check it over, find a benign cause and sort it for the price of a cheap connector and some labour.

The worst case (and by no means impossible) is the engine has an oil starvation issue and in essence results in running the engine without any engine oil...


I don't think I need to continue with what might happen then.
Write off time.

I'd appreciate comments off the Mercedes benz click mate.Never taken a car to a main dealer and never will.

Well to be fair you probs better not drive until repaired.

Possible clogged up oil pick up pipe in the sump due to long service intervals could be a possibility.

I would get the sump off it and change the pickup pipe and give it an oil change.

It gets serviced yearly and only does 10.000 per year.
It was cold and came on briefly....its just annoying.
Only comes on briefly.
My money is on oil pressure switch

A lot of garages nowadays just sook out the oil from the dipstick leaving the crud in the bottom of the sump.

Its certainly plausible

So how come that crud then gets into the oil pump pick up pipe if it does not come through the dipstick tube when changing oil?

A proper oil change pump sucks oil faster than it flows via the drain plug, any crud would come along.

Did we have the engine code already? If it has the oil pressure sensor, it would not have the dipstick tube and the theory about oil change and crud is gone anyway.
