What's the worst damage a blown fuel pump can do?

So guess I need to look for a used M96 Tiptronic motor.

Update.


I now know a little bit more about what's going but still don't know the exact cause of the failure.

Firstly, the shop admitted the fuel pump was misdiagnosed.

Second, compression tests showed low compression on the left bank of cylinders.

Third, hand turning the engine, they could feel it tighten & catch, then loosen u again during the rotation.

Fourth, the cam timing is out.

This sounds to them like a bent or stuck open valve, causing the engine to flood with fuel.

They're almost certain that it's not an IMS failure, but still want to drop out the engine the case to investigate. Sounds reasonable I guess, but now I'd rather use another shop, who has better M96 knowledge, to get a second opinion.

What do you guys think?

Let's see. We are on post #48 already. And on post #2 a knowledeagble Forum member suggested you go to another shop. Many more here have added the same comment. I think you know what you should do next.

i think you're making a smart move.

i would ask them if, since they essentially fixed the wrong thing (the fuel pump) before doing any actual work, to settle with the cost:
- parts for fuel pump (they can eat labor)
- labor for the actual diagnosis of the not-a-failed-but-good-chance-it-failed-IMS work they did.

push for that, tell them that since they didn't actually fix anything that was broken and ended up doing work that didn't need to be done prior to diagnosis that both of you should have to share the "mess up"

of course, like you said, since they have the car they're holding all the cards.

best of luck!

Good luck trying to negotiate with them. I’ve been there and the issue is the law sides with them and is designed more around dead beats that can't pay their repair bill. Sadly at least where I live there is not much recourse for the customer to argue with the supposed professional on their diagnosis. They would pull out some troubleshooting 101 and say my trained professionals followed standard process and it brought us to this conclusion so we fixed that first. Step 2 still not working keep looking.

At the same time you don’t need to believe everything they say. Heavy flooding does sound like a stuck, broken, bent valve. With that issue and the car running for limited time there should have been a bunch of codes coming up and the CEL lit on the dash while you had the car before taking it to the shop.
