BMW E90 320i Oil Pump GONE!!!
Discussion
Has anyone come across an issue with oil pump failing without warning on E90 320i! Mine went in for a oil service at a local garage last week. Its done 87k running fine until I went to pick it up. Started the car up within 30 secs oil light came on. Shortly after its started to sound like a old diesel and them should a tapping noise. Showed it to the mechanic who was confused to why it was asking for more oil when it was full. After a few hours the mechanic decided to stick it back on the ramp and take sump of etc.... Anyway now the engine will not start and have been told I need a new engine.
This is all very strange and don't understand why this would happen. I have had BMW's in the past and loved them to bits, but this have totally put me right off them. Any suggestions would be helpful to whats best way to sort this issue out. I am pretty sure BMW CS wont be very helpful unless I pay them to sort it out. The engine on mine is a N43 which seem to have common issues.

I hate to have to say this, but they may have drained the oil and not filled it up again.
Occam's razor. The simplest explanation is usually correct.The chances of a mechanic simply forgetting to put oil in are a lot higher than a working oil pump failing with no warning. Getting them to admit it or proving it may be a bit more tricky.
I fear you are in for some fun and games...
That's exactly my thoughts. drain oil, forget to refill. Move car, big red oil pressure light which doesn't go out after a few seconds. Realise mistake, put oil in, turn it over to let the pump prime, fingers crossed they got away with it but damage is already done :-(
If the garage is blaming the pump, I'd want to see it.

Hate to say this, but a few years back I worked for an established factory Jaguar dealer.
One tech did the oil service, took the car for test drive. Realised half way round he had not actually put any oil in it. Phoned "mate" to bring some oil out.
Got car back, filled up and handed over to customer.
The same scenario you have was then played out.
Customer had new engine fitted and Tech was sacked, but I think it took lots of shouting by everyone to sought out.

It seems strange to me that you can state the oil level was OK. My wife's 320 oil level does not register until the oil is warm, usually 15mins idling. If you ran your engine with the oil light indicating red for 15mins, regardless of what you believed the level was, you only have yourself to blame.
Well getting the garage to admit its their fault will be hard. All they are saying "it can happen at any point without warming". The engine was running for a few minutes and the mechanic opened the oil cap and check it was spiting oil. This shows the pump is working. Im no mechanic so unsure what check would have been done.
They did put ur back on the ramp and drained the oil out while i was watching. It was full amd filter was taken out to check also.

"It can happen at any point without warming (warning?)" is misleading bks. Oil pumps tend to be pretty reliable, not least because they are usually well lubricated, of course. They don't last long with no oil in them.They did put ur back on the ramp and drained the oil out while i was watching. It was full amd filter was taken out to check also.
Oil 'spitting' (sic) is no sign of whether the oil pump is working or whether the sump is full, it's just the cams throwing about whatever is there.
As you say you're no mechanic, which is why they think they can have you over. Almost certainly they ran the engine with no oil, then filled it and let the scenario play out.
Good luck.
Thank you REALIST123 for your input. I don't no how I would prove that is his fault unless there is a BMW master technician out there. I did speak to Steven at Lloyd Carlisle BMW who has been very helpful and he said sometimes the plastic guides on the chain break off. If this happens this can block the pipes to the pump etc. Unfortunately there are 100 miles away from me.
Not only is it unusual for the oil pump to fail suddenly, to fail directly you collected the car after service is just too much of a coincidence. They forgot to put the oil in it and then failed to road test it after service.
Proving it is going to be almost impossible without an independant inspection that shows a failed oil pump by inspection, not guessing.
get the car out of that garage immediately and get an independant inspection done.
