Help needed urgent...no oil pressure at idle

Post by sbmw » 08 Apr 2017, 10:18

I had a turbo replaced in my bmw 118d due to it failing, the garage didnt find a fault as to why it happened but it went again after 6 months. After it was fitted the second time, I drove away from the garage and the red oil can sign kept flashing on and off, I took it back and they dont know why its doing it but have said its either a faulty switch or the oil pump. Ive took the car to two garages to get it checked and both of them have said i have no oil pressure at idle. one garage has said none of the parts were fitted what should have been when refitting the turbo so they would re fit it all and it may possibly need an oil pump.
The second garage said he thinks its picked up oil on a big end, due to being ran without oil (which ive never done) and needs a new engine, this was after fitting a new pressure switch. ~x(
there is no knocking and the engine sounds fine.
i dont know much about cars so im at a loss on who to beleive. I dont want to be paying out for the oil refitting and end up needing a new engine. has anyone any ideas what it could be :((

Although it is possible that prior oil starvation has damaged the engine if the engine sounds fine and runs OK (so far....) it's almost certainly the oil pump which failed and that's what fired the turbo. Continuing to use it though will cause damage sooner or later. If the pressure has been replaced (correctly) I suggest getting a new pump fitted. Theoretically the guage itself could be faulty, but that seems unlikely?

We don't know what 'sort' of garage you've been using but go only to a BMW expert (or 'indie') as theyr'e usually referred to . There's one in most parts of the country.

I'm not referring to main dealers - but an indepedent BMW specialist. There'll be one or more around the NW I'm sure.

The BMW oil pressure switches can be a bit hit or miss
The only way to check oil pressure is with a gauge ( normally done by removing the switch and fitting inline) for testing only

If no one has done this yet that would be my first test (before condemning anything)
And then it would be a matter of working back from there

Depending on the test results depends on what to do next

Apparently it was tested by the second garage who reckons that the oil has been picked up on by the big end and says i need a new engine, but i cant figure out how he could say its defo that
