VACUUM LEAKS.

I would recommend checking for an intake air leak. Under the intake is a crankcase vent valve that can rupture as well as lines connecting to it. I would also check the rubber bellows from the air mass meter to the intake and make sure they are not split or torn which is also common.

The car will still run smooth, it's just the precat 02 lambda sensor will need cleaning or changing. Check for any chaffed wires first, it's easier enough to get to. You might just use a bit more fuel than normal. It's not a big job there's a video on YT how to change them

p1188 is fuel pump and p0170 is same problem but with air flow sounds like drawing in too much air and not much fuel. pump might be shot.

hope this helps

P0304 = #4 cylinder misfires
P0170 = Fuel Trim, Bank-1
P0173 = Fuel Trim, Bank-2
P1250 = this is invalid code for BMW
P1188 = Fuel control, bank-1, sensor-1 (pre-cat sensor)
P1189 = Fuel control, bank-2, sensor-1 (pre-cat sensor)
Vacuum leaks and/or sensor defective for the issues of the codes.
This error codes really need parts to replace. But you have to replace the thermostat first. Then clear the codes and see if any reappears,then replace defective part/s

James,

Based on the numerous codes and others who have experienced many of these problems, I would say you have a vacuum leak near the intake. I would also clean my DISA and ICV as well.

Please buy a Peake code reader (No..I don't sell them but I can vouch that they save time and money in the long run. A generic code reader will have you throwing thousands of dollars into repairing your car that aren't needed.). The Peake code reader is BMW specific and gives a more detailed result because the reader scans BMW specific codes that a generic OBD 2 reader can't.

This guy has an excellent video on how to clean your ICV and I think he has one on the DISA (which is next to the ICV):

Hope this helps!

These codes will have to be cleared and the car driven through a drive cycle, maybe a couple of times, is the check engine light off? Also you should check your MAF sensor it may need to be cleaned or replaced and makes sure there are no holes in your intake tubing. Hope this helps, let me know.

p1188: Fuel Control (Bank 1 Sensor 1)
p1189: Fuel Control (Bank 2 Sensor 1)
p0171 and p0173: These are very common codes on BMW's which can also be false codes, try clearing the codes and run the test again they may not come up again.
p1250: Never came across that....

im pretty sure p0170 is a misfire in one of the cylinders. 1188 no idea, if you know any mechanics ask them to look up the code at work. its free of charge and only takes 2 min.
