Finally solved engine code issue..P0170,P0173,P1188,P1189

Well I've had these codes for an year, I finally solved it.
P0170,P0173, P1188,P1189 they are all related to fuel system.

So I thought the problem was somewhere in fuel system, so I've replaced fuel pump, fuel filter, used seafoam, fuel system cleaner but nothing solved the problem.

Last week I finally replaced crankcase vent hose(part# 11611432559) with my friend's help, and surprise surprise. Codes never came back after I replaced it. I never thought it was the source of the problem!

I wanted to know why, so did some digging then I found this article.
http://blog.bavauto.com/bmw-e46/bmw-...0173-m52tu-m54

Too bad they didnt post this article sooner lol

Anyway, for those who's suffering from those codes, see if there's a leak from crankcase vent system. If one of the hoses are damaged, replace it asap.

USually lots of people damage #2 hose during the engine work, that's what I replaced too.

Hope this tip was useful

did you have any noise coming from the area like it was sucking air or air leak?

Well I have no knowledge of CCV system, but as far as I know it circulates the engine oil..I'm going to look into this system someday

Yes I've had some weird noise. It's hard to explain, whenever rpm reaches 3-4k, it used to make some noise like old truck(not the loud exhaust)..Probably caused by sucking air or leaking air from broken part of CCV hose.

.

On each compression and power stroke of your engine blowby gasses get past piston rings (unavoidable even in the best conditions). The CCV is designed to route these vaporous hydrocarbons (fuel) back into your intake system (through the PCV Valve) where they are burned along with the fuel injected by the injectors. Without the CCV system pressures would continue to build in the crankcase causing drag on the reciprocating motion of your pistons. Also and more importantly when you would shut down your engine with these HC vapours in your crankcase will condense and and mix with the fuel causing decreased lubricating properties in the oil.

This is just how I broke mine. I have the hose but how hard is it to replace?

CCV and it's extremities are usually the issue with most problems on here. It should already be known that it should be the first thing to be checked. I sound like a broken record broken record broken record broken record.

The CCV can also get stuck in a OPEN situation resulting in oil being dumped into the intake manifold potentially hydro-locking your engine. Mine fortunelty got stuck closed so it built up so much pressure it blew out the valve cover gasket.

I replaced the CCV and VC gasket and all is well. The DIY is a total pain in the a55 (will never do it again, would prefer to pay a mechanic to do it), but glad its over.

Hose #4 on the realoem.com diagram above also breaks from oil and torsion fatigue.

Easy fix. This post has pictures: http://forum.e46fanatics.com/showthread.php?t=773551

I had the same 4 codes for my 97 BMW 528i - P0173, P0170, P1189, P1188, my smok check failed big time because of this.

And this was the problem, it was a oil intake hose that was broken that connects to the base of the oil dip stick. Reach along the whole length of the hose, mine was not visible from the top of the engine like the one depicted in the pictures at this link

http://forum.e46fanatics.com/showthread.php?t=773551

Picture of hoses - mine was hose 4
http://www.realoem.com/bmw/showparts...94&hg=11&fg=15

As a second option:

Some say this boot can cause the same set of error codes although mine didn't have this problem.

Rough idle and OBD codes after cooling system overhaul

My first post here on the forum so I am hoping I follow protocol and it goes well. I am not starting a new thread based on what I have read on the FAQ's, I am sure I will soon find out if this is preferred.

Briefly I am a DIY type of person doing my own engine rebuilds and fabrication mainly on Toyota trucks old and new, vintage VW's and Corvairs. Also do some home construction, plumbing and electrical and find with patience and others wisdom I can solve most problems without the cost of a professional.

I bought my daughter a nice looking, high mileage 2001 323i wagon last year. It started running warmer and blew an upper hose recently. Being 19 and not really thinking she drove it back home several miles with the temp gauge more than likely pinned but to my surprise she made it back without blowing the motor.

After changing the oil and filter, I purchased a cooling system kit from Bavarian Autosport and replaced the radiator, water pump, thermostat, upper and lower hoses, expansion tank and sensors. Also picked up the Bentley manual.

The install went well and the car drove great on the test run, the temps look great.

Next day by daughter takes it for a spin and comes back saying it is stalling and idling terribly.

My Scangauge pulls OBD codes P0170,P0173, P1188, P1189 and P1250.

I have read several threads on the cause and effect of the these codes but I have not found if these codes can be triggered by a bad plug/coil?

If so should I check those first or should I go straight for a smoke/pressure/vacuum/MAF test, it's likely there was something or I likely cracked or broke during the cooling system overhaul?

Saw the following in this thread and found it very interesting and the reason I posted here. Thanks so much.

You should also read the first 2 links below in my signature, covers some very common problems.

Check the Long Term Fuel Trims at both warm idle and steady cruise between 45-60 MPH.

They typically should run between 0% and +2.5%, anything above +2.5% should be checked into, anything above about +10% will trigger lean codes.

Wow, that was a close call, overheating could've ruined the engine!

As far as the codes, I would replace the CCV system, it's a common problem and it's probably original.

Thank you. I think I saw a link somewhere for a complete kit, I'll check it out.
