Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
before this started happening, was there a power interruption, low battery?
Yes, the code does indicate a malfunction within the throttle body, but there are definitely some steps that need to be taken first
First thing. Remove throttle body and completely clean the blade and the bore with dedicated throttle body cleaner. Don't use brake cleaner...
Second - reinstall throttle body
third - turn key to on position without touching accelerator pedal, and leave it for a minute
then try to start the car
if it still acts up, then a vw-specific scan tool will be needed to perform the throttle body basic settings. It's a quick operation, but a generic obdII scan tool will not do this
Yes there was a power interruption. I had to replace the battery.
yep, knocked out the throttle settings
if that doesn't work, you can also try this procedure: http://www.goapr.com/support/ecu_a4_passat_early.pdf
Is there any tool that can reset this, or do I absolutely have to go the dealer? I do have vag com that I have used on my 2005 TDI.
wait...you have vag com?
I missed that last
Sorry it seems I'm having some inernet problems, if for some reason I don't respond right away you'll know why. Anyway yes I have a fully registered vag com. I haven't used it in a while and it probably needs updates but yes.
oh perfect...you can do this. here are the steps
connect, access engine (address 01), select basic settings (04), input 098, and click go
allow the routine to run, and field 4 should show adp-ok
if not, the clean throttle as I instructed and try again
that should take care of it
also, if for some reason 098 doesn't work, try 060, but I believe 098 is the channel for drive-by-cable throttle on the AEB engine
Beautiful. Can I also fix other problems with a reset? I also have a persistent problem with the oil pressure. I have replaced the pump and the sensor with no luck, the warning still buzzes after hitting about 2000rpm. I know this has been a problem with this engine but have not been able to find anything to fix it?
have you tested true oil pressure using a mechanical pressure gauge?
and that circuit is not one that is computer monitored, so vag-com can't help if it's electrical
I have hooked up an oil pres. gauge to where the sensor is. I don't remember the exact numbers right now but I believe it was within the parameters the manual calls for.
then doing wiring tracing is something sort of beyond what we can do here through the computer screen....
best bet is to have a set of Bentley Publishing wiring diagrams handy and start tracing
I was afraid of that. I had a VW tech at a dealer check for me and he didn't know what to make of it. luckily it didn't cost anything, he tries to help me when he can.
You think it is electrical though, not something that is a more common problem with this motor?
yes, on electrical
Ok , I appreciate your help and I'm going to get you paid today. I will reset it with the code you gave me but it will take a few days. My computer person (wife) lol, has to help with that part of it. Thanks I'll get back to you.
