Throttle body error

[thadeak]

Hi guys,

I got my cable working so i thought i would check for error codes.

While checking the engine (01) i got the following fault:

--------------------------------------------------------
VAG-COM Version: Release 311.2-N

Control Module Part Number: 8D0 907 558 A
Component and/or Version: 1,6L R4/2V MOTR HS D04
Software Coding: 04001
Work Shop Code: WSC 06335
1 Fault Found:
00670 - Throttle Position Sensor (G127)
27-10 - Implausible Signal - Intermittent
--------------------------------------------------------

I cleared the fault but it came back again.

Anyone got any ideas?

I have a 1.6L A4 SE 1997 (P reg)

Thanks for taking the time to look.

Did you do a Throttle Body Alignment? If not, try this:
TBA

its not much help but i got exactly the same thing when i tried TBA using vagcom and for my troubles i got an extra error on top of the one i already had:
17973 - Throttle Actuator (J338): Lower Stop not Reached
..been advised in another thread to clean the throttle body but not had the time as of yet.

though i did manage to get rid of the above error by disconnecting the battery for a good 15 minutes, reconnect it, turn the key so theres power but doesnt start the engine, leave it for about a minute then turn the key all the way (without taking the key out or anything) so the engine starts and let it idle for another minute.

i would like to know why my vagcom also errors out with "group98 not available" --i have a AGU engine which is NDBW so group 98 should be the correct one to change (as per instructions, engine was not on but electrics were).

which is NDBW so group 98 should be the correct one to change

NDBW has a throttle cable to control throttle position. there is a throttle position sensor but that relays information back to the computer where your throttle position is. it is not computer controlled by throttle position at the accelerator pedal. your problem is probably mechanical. or maybe TPS related.

hey dummi,

what's NDBW and how do i know if my car is NDBW ?

Thanks for the info.

What version of VAG-COM are you running? 311.2 as Shareware? Not supported. You need to buy a license to do a TBA.

DBW stands for Drive By Wire. Newer VW/Audis do not have a cable connecting the throttle to the accelerator pedal. They are electronically controlled and positioned.

Oh and I forgot, how do know which cars? Read the TBA page link I sent you. It addresses which cars are DBW.

Thanks for info bruce.

Ok i found out i do have a DBW Car using KWP-1281.

But still no go, however i have cleared the error code and i think it has stayed away.

I will check it again tomorrow.

Deak, what version of VAG-COM are you running? Are you running in shareware? If so, TBA alignment is not supported. You have to have the full program and a full license. You can buy the license in our store.

hey bruce,

Thanks for the info.

i am running 312 shareware, but i tried it with my friends registered version and it is the same.

I am concerned that if i spend out $99 on the full version i am going to get the same problem as is being shown with my shareware and my friends registard version.

Is it that my car just cannot be adjusted electronically?

Thanks again.

The procedures that Bruced posted the link to are perfectly fine for your ADP engine, but you need to obey the prerequisites!

There are certain test conditions that must be met before doing a TBA:
* No DTC's in the Engine Controller
* Battery voltage at least 11.5 V
* Throttle must be at idling position (keep your foot off the gas pedal), Engine NOT running
* Throttle body part must not be dirty (carbonized).
* Coolant temperature must be between 5 and 95C

In your case the Implausible Signal fault code is preventing the TBA, so fix that one, than do the TBA.

Hi Sebastian,

Thanks for the reply.

In my original post i asked what i should do about the Implausible Signal fault and bruce recommended the TBA.
But now you are saying that i should fix the fault before i do the TBA. but i thought by doing the TBA it would fix the fault.
If i have to fix the fault first before doing the TBA what do i need to do to fix it please?
I did follow all the prerequisites, but after reading back over them i notice the last one says the coolant needs to be between 5 and 95C, i guess this means i should idle the care prior to the TBA, then once the car is warmed up shut the engine off and try doign the TBA, correct?

Thanks again for yours and everyones help.

This software is totally amazing and without the help of all you guys here would be pretty difficult to work out.

Thanks guys,

Deak

Yep, this was correct. The TBA is part of the solution for this fault code, I'm currently putting some more detailed data about this online, so you can base your fixes on that.

Yep, that's suggested.

It's like with every tool, you just need to learn how to handle it - usually in cases like this a repair manual is quite a good help though.

Whats TPS?

[Sebastian]

TPS = Throttle Position Sensor

Hi,

Did you resolve this problem. The only thing I notice is the before image shows the throttle to be part throttle. It should read idle if you do not press the throttle. This could mean dirt in the throttle body preventing it going back to fully closed or the throttle cable not adjusted properly.
