Codes p1085 and p0174

Today I started the car and the SES light came on as I was taking it to smog. They ran the smog check and codes p1085 & p0174 came up. Oh by the way the car is a 2003 325i.

So I came home and check for any cracks in the hoses and found none, I took the DISA off and the flap is broken. So I ordered another one. I hope that works out the codes if not what else should I be looking for.

Clear the codes to see if they come back.
If they do, post freeze frame data.

Any decent OBDII tool will read/display Freeze Frame and Live/Realtime data. $30 or less for most smart phone apps and interface or there are nice stand alone tools for around $50.

What tool/App are you using?

Pretty much a CLASSIC case of E46 vacuum leaks, soft fuel pump or bad MAF. Not likely the MAF.

You need to read the first 2 links below in my signature.

Need to see Freeze Frame info if the SES/CEL/MIL is on and Fuel Trim values at both warm idle and a steady highway cruise between 45-60 MPH.

Read this thread - http://forum.e46fanatics.com/showthread.php?t=1057387

Read my "BMW 20 Questions" comments in this thread - http://forum.e46fanatics.com/showthread.php?t=1059972

Search YouTube for Scotty Smoke Test. Do what Scotty does or build a tester from related video. Remove the oil fill cap and make sure the crankcase fills up with smoke, put the oil fill cap back on and check for leaks around the valve cover, oil fill cap, dipstick tube and CCV hoses. Cracked valve covers are pretty common on the E46 as it ages.

Also read this thread about a bad batch of possibly defective CCV valves - http://blog.bavauto.com/15170/bmw-m5...s-ccv-cvv-pcv/

Not a fan of Dash Command, lots of color graphics, but seems to lack in what is actually needed from an OBDII last I was aware.

Touch Scan for $3.95 is a winner IHMO, one of the few Apps that deals with Wideband O2 sensors correctly.

Really need Freeze Frame data as it is answer questions quickly.

You want OBDFusion, but you will need an OBDII to Wifi adapter for the connection if you do not have one now. OBDFusion is by the same developer as Touch Scan for Android.

I think OBDFusion is like $10?

Jfoj have you found that OBDFusion reads wideband AFR voltage properly? I cant seem to get precat sensor voltages.

I am not running OBDFusion, however, I have supported a number of people using OBDFusion. I know with the latest App update the Wideband Pre-Cat O2 sensor bank identifier has been resolved.

I have an OEM version of Touch Scan I have been using and just actually purchased the standard Touch Scan today to play with.

Not sure if the App actually displays AFR in a ratio, but the Voltage should be properly displayed.

If you have OBDFusion, make sure it is the most updated version.

Some of the other Apps only display 1 of the Wideband Pre-cat O2 sensors and others have the wrong bank numbers associated with the sensors.

Um no disrespect to you, I assume you are new to OBDII and automotive diagnosis, but the displays you are posting really do not tell us much.

Palmer makes all these color eye candy graphs and gauges, but fails miserably in conveying any useful information IMHO.

Freeze Frame data is a specific page that only has fixed readings when the trouble code was triggered. There is likely a specific menu for Freeze Frame data but it is ONLY available while the SES/CEL/MIL is still lit, once codes are cleared the Freeze Frame data is cleared.

On tool graphing sucks on almost all Apps and even on my $2500 and up pro tools. Do not even post graphs from the tool it is a waste of your time and storage space.

This is what a decent graph looks like after the .csv data has been exported.

So a few comments.

Engine temp was around 138F when the Lean code was triggered. How long had you been driving before the code was triggered?

Is there any additional Freeze Frame info that includes Engine RPM and Vehicle Speed? This would be helpful to know how fast the car was moving and what the engine RPM was.

I do not know your tool, but there should be more info associated with the error in the Freeze Frame.

As for the the graphs, what can I say, as usual what to the vertical scales represent. There is not need to have to guess, why can't the developers actually annotate the scales??

Please choose to show the MAF reading in Grams/Second or G/S, there should be an option to choose Metric or Engine measurements, good tools allow you to selected English or Metric for individual measurements, not a single global setting.

You need to figure out how your tool logs, this would save quite a bit of time.

Would like to see logging of O2 sensors, MAF, RPM, Speed, Fuel Trims, Temps, Ignition timing. Logging is different that graphing, logging captures and stores the OBDII data and allows exporting it via .csv data for graphing with an external program. As I mentioned, most on tool graphing SUCKS even with high end tools.
