Hello,
This is my first post as I am new to this. Here's my story:
I own a 2012 BMW 528xi. I love my car, like I really love it. In January, my engine seized. A couple of weeks ago, my mechanic told me that he found an engine that has 39K. I was excited since I have been renting a car for the past 3 weeks. I asked him to send me the VIN number of the car the engine was taken out of. He said he needed to buy asap because there is a high demand for it and since I need a car because I have a family and I can't keep paying for a rental, I had to trust him, he's a mechanic after all. Anyways, I kept asking him to send me the VIN number. Once he sent me the VIN, I bought the carproof and I realized that the engine had 55K before it was salvage and it came out of a 2016 428xi. I paid $8,669 to replace the engine. Today, I was told by the dealership that the new engine is a N26 not N20 like I had before. The Powertrain malfunction and the check engine are both on and I have absolutely no power. The OBD reader says that I have Fuel High Pressure, Plausibility, Cold Start Pressure Too Low.
Could someone help me figuring out if I should sue my mechanic and the junk yard or do you guys believe that my car could potentially by fixed. Thank you. Mo

The N26 and N20 are almost identical. Fix the problems and you should be fine, but the mechanic should do that for you at no additional charge.

Thanks, appreciate it. I was really worried when the dealership told me that I would need thousands of $$ in coding and that parts won't be compatible.

As above post says, the engines are effectively the same less a few parts that are different. Shouldn't be too big of an issue to get the problems sorted.

Yes N20/26 are same save some few parts.... but OP can you clarify why are you at the dealer?. And the mechanic who swap the engine for you. Did he just clear the codes and gave you the keys to drive... you gotta get that guy resolve your problem.

The dealer is going to be expensive. They don't deal with swap engine. Dealer always say you need a new engine.. new this and new that.

Yea he cleared the codes. The car has no power at all and the powertrain malfunction in on. He cleared the codes and gave me the key. I went to the dealership because I was worried after the engine swap. My mechanic said that his job was to repalce the engine. "You brought me a car with a seized engine and I replaced the engine. If the problem is a fuel pump that is not engine related. That is what he said to me. That is why I am very lost now and I honestly don't know what to do.

To be honest, I am worried that he broke the high pressure fuel pump. I was watching installation videos, and it requires to move the crankshaft to dead end before installing the fuel pump. Not sure he did that. He told me that the new engine did not have a fuel pump and that he had the pull it off my seized engine.

Very sorry to hear this horror story 😬 not too experienced but if you can't get that sleazy mechanic to fix it, I would buy used parts and take the car to someone else

Lame. His job was to give you an engine in proper working condition. I'd get the car fixed, then sue this doofus in small claims court for whatever it costs to finish the job he was supposed to do.
