Vag Reads Error When Doing Throttle Body Alignment

xix-05-2008,x:42 PM

Hi,
Hopefully someone out at that place will take the respond to my trouble...
I have a 1996 A4 B5 that's got the poor idle problem, accompanied by hesitation on acceleration (more oft than not).
Having read numerous posts I bought a 3rd party interface from ecutools.com and have used VAG 409.one to obtain a few fault codes. I then decided to clean my throttle body...which I did today (surprisingly dirty) and in the procedure discovered the engine breather pipage (the plastic moulding) had fractured. I bought and fitted a new one today equally well.
I reassembled the throttle body and hoses etc and then tried to perform adjustment of the throttle trunk using VAG-COM.
Still, when I follow the procedure suggested on VAG'due south website I get a momentary green calorie-free ( "run" is displayed in green lettering, forth with values in the other 3 rectangles) merely after a split 2d I get the message "mistake, 098 not bachelor" (or very similar). I can hear the throttle trunk whirring abroad for nigh 10 seconds before information technology stops and moves back to the idle position (it doesn't seem to movement more than a few millimetres during the whole procedure)
When I then wait at basic settings the discussion "error" appears in the rectangle to practise with throttle body.
My fault code is as follows:
17967 - throttle valve control office (j338) : Fault in basic settings
p1559 - 35-00 - -
Am I doing something wrong?
Does my automobile have a further fault that wasn't in that location this morn?
Is my VAG software not working properly?
Perchance I can't reset the throttle body on my car?
Past the way, I have tried other methods of adjusting the throttle body...opening the bonnet and the driver's door and turning on the ignition while humming Deutschland Uber Ales and VAG tells me information technology's nonetheless got this 17967 fault...the car drives far better at present than it did yesterday and idles quite smoothly, albeit at about 900rpm. It doesn't hesitate at all now either...and so I'm fairly happy only I know there's still a trouble.
Tin can anyone shed some light on this delight?????

If you are getting a fault code on the throttle body itself that is why information technology cannot perform the alignment.

Try clearing the mistake code and and so doing the alignment.

Does sound like yous might need a new throttle body.

I tend to agree, you accept got to be really careful with the TB when you clean information technology.

Try the in a higher place, clearing the code and then try and re-align. But if the code comes dorsum, I would say its time for a new i.

Did y'all employ anything to make clean it? WD40 or Carb Cleaner? I use WD40 and that seems to be ok, cleans all the crud off and ways you don't have to practice also much fiddling with the butterfly valve.

Hope this helps.

Thanks for your replies.
I used spray blazon carb cleaner and I too removed the butterfly so that I could get the whole matter spotless. This fault wasn't present on VAG before I cleaned it so am I to assume that some carb cleaner has found its way into the electrics of the TB? If so it may dry out and recover???
I wondered if I might have a cleaved wire somewhere near to the electrical plug that is giving the problem...do you recommend a way of testing this...I take a digital volt meter.
The strange thing is that the car is running then much amend now than it did...information technology hasn't hesitated once on acceleration and it is a joy to drive once again.
I recall I might leave it a few days and try adjusting the TB once again. I tried immigration the fault code many times yesterday but it reappears most immediately.
If I do demand a new TB can you recommend somewhere where I can get one at a reasonable cost?
Cheers.

I approximate its possible that you have damaged something when you took the TB apart.

It might be worth having a look at the electrics, seeing if its ok merely I call up its the servo that controls the valve that might exist cleaved or damaged.

Take a await in output tests in the engine controller, run into if any of them include the TB (Although you will merely get the same fault every bit you accept during the reset)

You could do a run and mensurate the TB angle (Block 003, column 3 on a 1.8T engine). That might show whatever problems with how the valve is or isn't working....

I am non certain where you would go for this.... GSF??

I would endeavor clearing the adaptation values by going into in Adaptation and clicking save in channel 00, and so clear all the faults that volition clear and try re-aligning the TB again.

Thank you lot Longman and Smokey0123 for your replies.
I can remember seeing a TB bending value in VAG-COM before I removed the TB for cleaning...I'll have another look later on today if I go time and allow you know what I observe.
I tried clearing the adaptation values yesterday in the way that Smokey0123 suggests but that didn't make any departure.
Having Googled "Throttle body Audi A4" I see there are a few alternatives available...there is one on Ebay for nether �100 delivered that is reconditioned and offers a two twelvemonth warranty and yous send your failed part dorsum to them afterwards for reconditioning. Do you accept any thoughts/cognition about these?
Thanks once more guys for your very knowledgeable and fast replies...I'm somewhat stumped equally to how I might have damaged the TB because I was and then conscientious with it (or and so I idea)
Thank you!

I managed to practice some VAG-Com testing last night.
Group 098 displayed the post-obit:
Throttle Value Pot Voltage 4.4V
Throttle Drive Pot Voltage 3.72V
Operation Condition Idle
Adaptation Status Mistake

I looked at group 003 but that gave me spurious readings for throttle angle.

I call back I plant throttle angle in group 010 - at idle (840rpm) the throttle bending (TA) fluctuated between -2 and -iii, then I increased revs to 2K and the TA climbed slowly to x, went back to idle and the TA dropped back to 0 subsequently well-nigh a minute.
Interestingly, while the automobile was running at idle the engine speed % value kept increasing every few seconds although the engine speed remained constant at 840rpm.

I tried resetting the fault code but it kept coming dorsum after a split up 2d, and I also tried to exercise a TB adjustment but there was no modify there either.

So information technology looks as though something in the electric function of the TB has stopped functioning correctly but strangely enough the car runs and performs fine.

Given that I'k strapped for greenbacks at the moment will it exercise whatever impairment to live with this condition? What is the result of not fixing this trouble...would it be poorer fuel consumption, unacceptably high frazzle emissions, sudden breakdown?...I'd value some advice on this please.

Thanks in advance!

Cheers

I am not really certain whether information technology would injure if you where to carry on driving, yet, I wouldn't rule out a sudden break downwards.

Peradventure, if there is a problem with it, it the ECU could be running the Trottle Trunk in a safe mode with basic settings, which would account for the car running ok now.

However, you won't get so practiced fuel efficiency or full power in safe mode.

Simply a thought actually, not 100% on this I am agape.

Thanks Longman

Are the electrics in the TB complicated...where can yous buy a new "servo that operates the valve" in the TB...I assume you must exist able to go these things considering at that place are a couple of companies that brand a living from reconditioning TB'southward.

Any ideas??
