      TIPS & FEATURES AEuro-Forum - READ!!   10/25/2016

      Tips and Features of AEuromotive Technical Site 1.    Quick Peek Feature:       Hover over any Topic/POST within a Specific Forum or NEW POST.  You’ll notice a pop up window displaying the Original (FIRST POST)
      tab containing the vehicle Information and the Diagnostic Issue.  Next to the FIRST POST tab, there is the LATEST POST tab.
      This is the LATEST Reply to that Topic/POST.  It may contain the FIX,NOT FIXED, or UPDATE to the ongoing Topic/POST. 2.    SEARCH Feature: If you have not tried the SEARCH Engine, I’d advise that you do.
      START at the YELLOW Arrow. Then choose from the flip out flag where you wish to begin your initial search. 
      Use Word, or Words separated by a space or comma.  The more words you enter, the wider the search. 
      DO NOT use words like: the, of, abbreviations will not work.  BE Specific!       You’ll be directed to the second “Refinement Page”.  From there, you can narrow the search criteria, by clicking
      +MORE SEARCH OPTIONS. From there attempt to use both sides of the OPTIONS Menu. 
      USE the SEARCH Engine and get comfortable with navigating it. 2a. TSB/SIB/Recalls/Campaigns SEARCH Feature:       Currently, I am working on having the Feature to SEARCH ONLY for TSB/SIB/Recalls/Campaigns for this site. 
      This is in YELLOW type, as it is currently under development.  I hope to get this to work within the initial SEARCH
      Feature when you CLICK in the SEARCH Field, that "flag" will kick out.  In that Categories list, you'll see a TSB link.
      Within this link, when clicked, you'll choose the MAKE of the vehicle.  Immediately, ENTER all of the WORD or WORDS
      within the TEXT SEARCH FIELD. CLICK the MAGNIFYING GLASS, OR ENTER.
      ALL Technical Service Bulletins RELATED to THAT MAKE will be SEARCHED, and DISPLAYED. 
      Quick SEARCH Feature has been refined for shorter results. I have already ran through some tests with BMW, Mercedes and VW/Audi.        IT WORKS!.  Note! I still have hundreds of TSB/SIB/Recalls,Campaigns, and other related Technical Service Bulletins!
      And this is NOT counting the Domestic and Asian Vehicle MAKES!!  OH, Whoa is ME!!
      Approximately 789 additional FACTORY TSB's in General to do for European.....over 1400 additional TSB Documents
      for Domestic and Asian.  I WILL GET THEM DONE, BUT i HAVE TO DO IT MY WAY (I GIVE GOOD MASSAGE)! FEEDBACK IS ALWAYS WELCOMED....GOOD OR BAD.  GROW A SET AND TALK TO ME.  IF SOMETHING ISN'T RIGHT,
      TELL ME.  MY SKIN LAST MEASURED WITH MY CALIPER WAS 4.378.9" THICK!  USE THIS AND MANY OTHER FEATURES MY FRIENDS! PETER AND I ARE TIRELESSLY ATTACKING THIS SITE WITH $$$$$$
      AND HARD, TIME CONSUMING WORK.  IF YOU HAVEN'T NOTICED............YOU ARE NOT LOOKING!! 3.    Technical Documents Tab: By clicking the Technical Documents Tab, you can SEARCH for TSB’s, SIB’s, and Campaigns.
      and Recalls are available to you.  We have over 1500 document of Factory Level that can help. 
      Again, USE the SEARCH Engine to narrow your results.  Get comfortable with using this great resource. 4. HYPERLINKED Text Within REPLIES in the Topic / POST, Hyperlinks can be added to that reply, or an original Topic / POST.
      It is important that the browser that you are using is set to OPEN a new TAB when a click is clicked. In MOZILLA Browser, quite easy to do.
      Go to the top of your MOZILLA browser and click TOOLS > OPTIONS > GENERAL (on the left sidebar). 
      Then check the check box that states "Open New Windows in a new tab instead" Then, when you click a helpful Hyperlink, a new tab, and windows will open to your top right and will go to the
      hyperlinked page! WARNING!! I would advise, if you are NOT "Computer Literate"....NOT to attempt to Hyperlink Text, as this
      may cause damage to your POST.  ONLY Experienced, "Computer Savvy" Technicians are capable of
      doing this action. 5. STORE Page Check out our STORE.  We have a number of items from Diagnostic Machines, Scanners, Software,
      Training Manuals, and anything that you may wish to purchase.  If it's not there....contact us regarding
      your needs.  We are there to service your everyday Diagnostic and Computer needs.....ALL OEM. NONE of our scanners and Diagnostic Computers are "CLONES, or CLONED" Software.  It is all
      within the "LEGIT" realm for ONLINE and OFFLINE Diagnostic Purposes.  Technology can be your
      friend........or your enemy.  It is your choice.............you get what you pay for HERE!! 6. Member Map This FEATURE is used by ALL Members to locate another Member.  This FEATURE is useful to: Locate another Member in the AREA for help Locate a Member who can help your customer stranded in another Member's Area Quick Location of all the Members of this Collective Help each other make $$$$$$$$$$$$$ Please click the Member Map tab, and register your location.  This system works well for
      all of the Members and may provide you with valuable information, in which to promote
      your Facility!           7. CLOSING/Updating your Topic/POSTS            It is imperative that ALL Topic/Posts are updated on at least a weekly basis, while also, CLOSING your
                Topic/POSTS when you have completed your repairs.  ALL POSTS MUST be CLOSED within 21 Days, or
                updated to keep your ongoing POST from being suspended.           Every time a Member Logs into the site, that member can check how many POSTS he has opened. 
                When first logged in, you will see an initial screen with all of the ongoing POSTS that are OPEN.

                If there are more than 3 OPEN or ongoing POSTS, the Member will NOT be able to add another
                Topic/POST, until one of the 3 POSTS are CLOSED.  If by chance you missed that opening screen
                follow this procedure to see what POSTS are currently OPEN.          Click the “Activity” tab > then click “My Activity Streams” > then click “My Open Topics.
               My Open Topics LIST has been modified to ONLY show the OPEN POSTS without REPLIES. 
               This will make for shorter SEARCHES of your OPEN POSTS.          This will display all of your current OPEN POSTS.  From there, you can close them, if you forgot to,
               or they are NOT FIXED, or FIXED.  PLEASE, be detailed in the last REPLY, so this will help another
               Member at some time, whether you FIXED or did NOT FIX the vehicle.  Details are what help us all, so
               please be a productive Member of this site.  I for one will appreciate your efforts. There is a NEW Feature that I have had out Guru Programmer to the site: 2/13/2017 This feature incorporates a "Back to TOP" Button at the bottom of the POSTS Some POSTS are lengthy in information, which makes scrolling the page, or pages time consuming.  Every little bit
      adds up while researching.  TIME is $$$$$, as I always preach.  So now, when needed, you can scroll to the bottom
      of the POST, then click the "Back to TOP" button to go to the top of that POST.         8. FACEBOOK & Twitter Links         For now, located by the AEuromotive Logo, you'll see some small Facebook & Twitter links.  Mind you,
              these will be replaced with larger ICONS.  This is being worked on as I type.  My coder is getting this accomplished.
              For now, they are linked to the AEuromotive Facebook, and to Peter's Twitter Account LIVE.  I DON'T "TWEET"
             You wish to know my opinion...........better grow an extra inch of skin, then call me and ask.
             Try them, use this to contact Peter.        Again, when this TEXT turns White, it is totally implemented!         9. PICTURES IN POSTS         This FEATURE has been implemented.  When inserting a picture within the POST, make it as small as possible
              to fit within the constraints of the frame.  Any one can then CLICK on the PICTURE to open a new window and
              see the LARGER Version that you had uploaded to the POST.  Please try to keep the original picture within
              2 - 3 MEG in size!  Once you upload the picture, click on that picture and use the corners to shrink
              to fit.
             You can also resize the pictures you add to the POST.  Once you save the POST, click on the picture, you'll
             have the Feature to scroll through all pictures resized in your POST.       10. F5 "REFRESH" Feature         This has always been a WINDOWS Feature, but I thought I'd put this up for those that didn't know:         I have tested FF, IE7, Opera and Chrome.    F5 usually updates the page only if it is modified. The browser usually tries to use all types of cache as much
             as possible and adds an "If-modified-since" header to the request. Opera differs by sending a "Cache-Control: no-cache"        CTRL-F5 is used to force an update, disregarding any cache. IE7 adds an "Cache-Control: no-cache", as does FF,
            which also adds "Pragma: no-cache". Chrome does a normal "If-modified-since" and Opera ignores the key. 11. InfoServer 1 and VMDiagnostics Server InfoServer 1 and VMDiagnostics are already in progress, as InfoServer 1 will be comprised of the following Technical
      Information: 1. ISO Diagnostic Programs updated on a weekly basis.  You will need an ISO Application to unzip, or run these programs
          on a "Virtual DVD" 2. PDF Diagnostic Training and Information Documents, requiring you to have Adobe Acrobat Reader installed on your
          computer.  You can get it here for FREE: https://get.adobe.com/reader/ 3.   InfoServer 1 is completed and ALMOST ready to connect to this site.  We are waiting for our security license, and our
           OpenVPN setup.  The SSL (Secure Socket Layer) Certificate is in the process of being issued. And STILL waiting!! 4.   All European, Asian and Domestic Makes and Model Information and User Manuals 5.   All Downloads from the InfoServer 1 will be monitored by Platinum Members that do so.  So I can run a report of
           what and when a download occurred.  Limit is 6 - 8GB per Day VMDiagnostics will be comprised of the following Technical Information: Launch Date for February 2017 This InfoServer 2 is a 4.6+GHz machine with up to 64 Gig of RAM and SSHD (Solid State Drives)
      as to prevent lag and slow response as most Virtualized Systems are. This is no "Puppy" System,
      "Full Tilt Boogie" Machine!! 1.   Virtual Programs running LIVE on this Server for Members to access and use Daily (Charge per Day Access) a.  Mercedes
      b. BMW
      c. Mini Cooper
      d.  Volkswagen
      e. Audi
      f. Any other European Make that I can get their FACTORY Programs to run on a  "Virtual Platform"
      g. Domestic Makes (GM, FORD, Chrysler, etc.)
      h.  Asian Makes (Honda, Hyundai, KIA, Mitsubishi, etc.)
      i.  Any Diagnostic Programs that can be "Virtually" operational, I will do so With ALL of the above upcoming Technical Systems coming on line....YOU will be responsible
      for Downloading and Installing these programs...............NOT me.  it is the responsibility of the USER,
      that will have to sign off on the agreement to download and install the programs.  Instructions are included
      in the folders. Please Note!  I will be adding to this ANNOUNCEMENT periodically, so keep coming back to this, and see what other
      Features I have added.  I still have a dozen to add to this ANNOUNCEMENT, as we have upgraded this Forum since
      yesterday 10/24/2016.  Stay Tuned!!

Smoke test the EVAP system, check the charcoal canister, roll-over valve, ALL hoses and the purge valve.

And last but NOT least............REPLACE the Gas Cap.

I really try NOT to be sarcastic, but my post states that I have already done all of this....:)

Trust me, when one is doing 1,568 things at once....like I do..........sometimes, I fail to see some things
that I should have!! :884_no_smoking:

And trust me Michael, I don't mind sarcasm, Frank Zappa and I go way back! ;)

Sorry about that, I TOTALLY missed it, as I was Remote Accessing 2 systems, while reading POSTS! ARGGGGG
Did you smoke test this system REALLY Good??

I have seen hoses internally collapse and restrict purging of system.  I'd just for GP, go back over the entire system
to see if something slipped past you.

If anyone knows these vehicles...it's Peter.  Stand By, calling him right now for you!

Smoked it before replacing components and after reassembly...

P0497 sets when The computer runs a EVAP self test. It opens the purge solenoid and closes the vent.
It's looking for the fuel tank pressure sensor to show a vacuum. Normally between  5 and 10 in H2O.  
Its not seeing a change on the Fuel Tank Pressure sensor. 

Check your vent and purge solenoid operation.
Purge is normally closed command it on it should open and you can then blow through it.  
Vent is normally open.  Command it on and you should not be able to blow through it.

If they test OK.......... You have a leak in the system!  
Smoke it while doing a system seal with your scan tool. Use black light oil get out your black light and glasses. 
Gas caps are common, Vent solenoids and also prone to failure (not sealing when closed because of dust or dirt intrusion).
I have seen fuel sender seals failed on top of tanks also.

The P0455 is a large system leak .  

Normally see both these codes set together.

On systems using a FTP pressure sensor you should be able to use the data from that sensor to aid in diagnosis.
When system goes into purge does FTP show vacuum? No change?
So FTP on this car: 1.5v and up is vacuum, 1.5v and less is positive pressure.

Pulled this from service:
" The control module tests the evaporative emission (EVAP) system for a large leak, or a stuck closed EVAP
canister purge valve. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the
EVAP system vacuum level.

When the conditions for running are met, the control module commands the EVAP canister purge valve OPEN and
the EVAP vent valve CLOSED. This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum
level, the control module commands the EVAP canister purge valve closed, sealing the system.

It monitors the FTP sensor input in order to determine the EVAP system vacuum level. If the system is unable to achieve
the calibrated vacuum level, or the vacuum level increases too slowly, a DTC sets. "

At this point might suspect canister vent solenoid or possibly a bad FTP.

Seen some issues with these engines too! Sent quite a few back for warranty under dealer for internal engine issues!

Another item might be to check FTP sensor for proper operation.
I will check to see what the readings should be.

Fuel tank pressure sensor should read 1.5 volts with gas cap off.
And yes a faulty vent valve is the most common problem for large leak P0455.

This one is FIXED with the purge valve replaced at the intake manifold.

Thanks for everyone's input
