Hey Guys I'm a Newbie with a P0170,p0173,p1188,p1189 problem

Hello I'm New To The Bimmer Scene Bought A BMW 528it Wagon about 8 months ago with a ton of problems mostly sensors but with good Milage (111,5xx) for a 1999...I Have 4 codes Constantly There tormenting me..I've done everything I could do with this problem and still I'm getting nowhere fast!
I Have Terrible Milage (6.5 MPG) And Still Getting Fuel Trim Codes (p1170,p1173,p1188,p1189)Since I've been chasing this problem I've found countless others and fixed them all like cracked ccv hoses so I replaced whole ccv and vacuum hoses from behind engine deteriorated and faulty O2 sensors ect ...but replaced all and still have problem.. I know it's a air leak problem that in return gives me a too Rich or lean mixture and makes me burn more fuel than normal (i get 6.5 mpg on the dash computer) and still I get the p1170,p1173,p1188,p1189 I've Checked The Intake Boot Rubber And All Hoses Countless times Sprayed My Life Away With MAF/throttle body Cleaner found few vacuums like from the intake manifold and other hoses but got fixed new gasket and everything ..but codes still come back!
I've even inspected my DISA valve TWICE But It's In Good Condition even replaced O Rings on it.. And still.. I'm lost.. I've order the Vanos seals and should b here in a week to replace those too.. But after that Idk what to do.. I've suspected the fuel pressure regulator but never got around to it..idk my fuel psi or how it's supposed to be...
Since looking for the source of this supposedly air leak problem I've replaced the following items..

1. Both oxygen sensor before cat
2. Both camshaft sensors
3. Intake manifold gasket
4. Mass Air Flow Sensor
5. Thermostat
6. All 6 Spark Plugs (twice)
7. Oil Filter Gasket
8. Valve Cover Gasket
9. Sensor in between both camshaft sensors can't remember the name.
And a lot more stuff that I can't remember right now... Also the p0340
(inlet camshaft sensor)code comes on after a hard start witch happens like 1 in 15 starts but I replaced that sensor with a tested new one.. And when I tested it again it seemed to work.. Ps the p0340 code is rare but it comes up every now and then.. I originally had a lot more codes including this one but little by little I resolved them all accept these blasted fuel trim codes that keep coming back to laugh at me.
So PLEASE .! any ideas or opinions will DEFINITELY matter at this point In time for me .. Oh Yeah! I Forgot to mention that I personally don't do this I just stand there while my mechanic works I just tel him what to do and he put in the work lol

Start by typing /misfire f3 in the bestlinks, which returns, this, among others ...
- How to diagnose a BMW E39 engine misfire (1) & a cold-engine intermittent misfire (1)

Then clear the codes, and put this (or similar) obd scanner on while you drive around the block a few times...
- - Cheapest CAN OBDII scanner on the net that reads DTCs, pending codes, & clears codes

See what code pops up first.
Diagnose and fix that one.

Then move on.

You have a substantial air leak somewhere. Get the engine smoke tested.

The codes indicate that the engine computer cannot further compensate for the air leak.

http://www.obd-codes.com/p0170

http://www.obd-codes.com/p0173

P1188 Fuel Control (Bank 1 Sensor 1)

P1189 Fuel Control (Bank 2 Sensor 1)


What brand of O2 sensors did you install?

It makes no sense though because I checked everywhere... I was once told in a shop that it was smoked tested when they replaced the pcv but I highly doubt it now.. Smh

Get it smoked like edjack stated. You have a major air leak. Maybe your intake to head gaskets have air leakage which it's a possibility. Also code 1188-1189 could be a fuel pump / pressure issue. Get that tested also.

What really doesn't make sense to me is all of your codes point to lean conditions, but if you are averaging 6.5 MPG, you are running massively rich. That almost sounds like either the MAF is not telling the ECU that the correct airflow is occurring or somehow air is entering the exhaust stream between the combustion chamber and the O2 Sensor. I know you said you replaced the MAF. Did you replace it with an OEM one? It seems like there are a lot of posts describing problems with other brands.

ID:	501144it turn out to be a loose connection in the hose shown in picture there's too much pressure for it to fit nice and tight if only hose was a lil bit more flexible smh bout to do a custom job and see if it stops problem.. I have replacement hose but it's under pressure since it can't bend the fraction I need but let's see what happens

Might be better to buy the proper molded hose from the dealer.

That hose in the pic is not under pressure. It connects the valve cover to the CVV and is under slight vacuum. It takes the oily air from the valve cover into the oil separator part of the CVV. The oil is separated out and returned to the sump. The air is directed to the intake where it burns off.

There is a small o-ring in the connector which must seat properly when the connector snaps into place in order for the hose to seal to the valve cover. It is wise to put a bit of grease on the o-ring so it doesn't kink or split when the fitting is snapped into place.

After the hose is attached/sealed correctly, have another smoke test performed to make sure you don't have another leak elsewhere. It sometimes takes a while, maybe 5 minuted, for a leak somewhere deep in the system to show up.

The stock hose leans up against a conetor/sensor down there and it pushes against it and that DIDINT let it clip on right so I replaced the hose with a rubber hoseClick image for larger version

That's just fine as long as both connections are tight. Don't replace one vacuum leak with another.

Looks good but from the pic it seems like it will interfere with taking off the the oil filter housing cap during an oil change. I suppose you can disconnect it and move it out of the way, if that is the case.

I'll be interested of this fixed your car. Please report back.

I should probably take a look at that. I've had P1188 and P1189 for a couple months now and haven't found anything.

By the way, nice touring!
