BMW E90 320i N43 Engine Oil Pump Failed
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.
Has any come across a oil pump to suddenly fail without warning? Also if it comes to me getting a new engine can I put a 318i N43 in the car.

Didn't you post this the other day?
It sounds to me like they forgot to fill the oil and they've knackered it but are denying responsibility
It's very odd for a pump to fail instantly with no prior warning. Bit of a coincidence it happens after having the oil changed isn't it?!
I doubt you need a new engine, some of it will be fixable . IMO you need it stripping and inspecting, you might get away with a new oil pump and set of big end/crank bearings depending on how long it's ran with no oil..get the head and the sump off and see what's going on, with regards to the state of the bearings and any debris that may be in there.

There's probably nothing wrong with the engine - yet. However it obviously had no oil pressure hence the hydraulic lifters started rattling and now it won't start because the lifters can't operate without oil pressure. It's vanishingly unlikely anything happened other than they forgot to refill it with oil. You need to get it away from them, have it examined by an independent expert and sue in the small claims court if necessary for any repair costs.
