VAG-COM: Airbag Control Unit Diagnostics

Does anyone have experience with VAG-COM and airbag control units from the year 2001?
with the part number 6Q0 909 605A. According to the VAG-COM manual, it is...
it may be the case that with some tax authorities, this number indicates...
"Control unit error (65535) is set and cannot be cleared."
(Airbag control unit replacement)
"The airbag warning light is on in my car, and I want to read the error codes, but I'm not sure how."
I'm not sure if this will render the tax software unusable.

I've had error codes cleared at a Volkswagen workshop before, and that time...
It works.
My question: Can I clear error codes with VAG-COM Version 310.0, or will something else happen then?
Error code 65535 set.
If so, I would be interested to know why it works with VW testers.
and not with VAG-COM.

Sure, no problem. Here's the translation:

"Thank you in advance."

Regards,
Christian.

hello,
I had an airbag control unit with the part number 6E0 909 605A in my Lupo, manufactured in MJ2001 (November 2000).
The error occurred there, and the control unit was damaged.
I went to Volkswagen and told them that I had already read the error codes using VAGCOM, and that this particular error code was now present. I had a printout from the internet showing that it's a known issue with this series of control units.
VW then replaced the control unit with a completely free-of-charge gesture, without any hassle.
But perhaps it's not always advisable to say that you had the vehicle scanned with VAG-COM; it probably depends on the dealer.
greetings

I can't find part number 6E0 909 605 A anywhere. Could you please check what the correct part number is and which VW part it replaces?

Does anyone have experience with VAG-COM and airbag control units?
from the year 2001 with the part number 6Q0 909 605A. Refer to the VAG-COM manual.
it states that it is possible that with some tax devices, this...
'An error code (65535) indicating a problem with the control unit has been set and cannot be cleared.'
Deleting is not possible. (Replacing the airbag control unit)

Yes, it's due to a bug in the firmware of that control unit.
If VW replaces the control unit, you will also see this part number.
has been discontinued and replaced with 1C0-909-605-A.

The airbag warning light is on in my car, and I want to read the error codes, but I'm not sure how.
I'm not sure if this will render the tax software unusable.

My question: Can I clear error codes with VAG-COM Version 310.0?
or will the error 65535 be set.

It's impossible to say for sure. It seems like there are some variations (in color).
certain license plate designs are more susceptible to this issue than others, but we...
We don't have enough reports to say for sure. It's just a risk.

But consider this: if you have a control unit with a known error.
Does it not think it would be better if you got rid of that thing...?

I've already had error codes erased once at a Volkswagen workshop, and then...
Did it work? If so, I'd be interested to know why it worked with...
It works with VW testers but not with VAG-COM.

Yes, us too!

I had contact with people in the development department of the manufacturer about 1.5 years ago.
from this control unit. They also couldn't find anything that VAG-COM reported incorrectly.
does.

hi,
It should be the number 6E0909605, without the 'A'.
It was replaced by a 1J0... or 1C0..., depending on the version. I can't tell without taking the whole car apart.

In April 2003, I sent an email to Rosstech stating that the error had occurred in my Lupo.

greetings

My STG 6Q0-909-605C also failed when connected to VAG-COM (those who can read will have an advantage ). It was then replaced with a new one, at 100% warranty coverage, for €45, replacing it with the device IC0-909-605H. A bittersweet situation (a crying [cost] and laughing [get rid of the faulty control unit] eye).
Bursting with energy.
Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hello.

Are these problems specific to the VAGCOM tool, or do they also occur with other independent diagnostic tools?
Yesterday, the control unit was replaced at Audi. This followed a diagnosis performed at an independent workshop on December 24, 2003, which identified error codes 65535 and 00588 (driver's airbag speed sensor - intermittent). The intermittent error could be cleared, but the other described error could not. As a result, the control unit was replaced. The car is an A4 model from 2001 with 95,000 km on the odometer.

... if I interpret Uwe Ross's statement above correctly, then that is at least not something we can rule out.

had a document from the internet with it, which stated that it was a serial defect of this engine control unit series.

I've already searched on Google, but I can't find anything really suitable. It would be great if I could buy the 698.52 Euros worth of items for the new group.

Hi icke01,

I found something here... it might be interesting.

If the required control unit is not included, we can 'reset' your airbag control unit, which means deleting the crash data or reloading the software.

Is that possible...? / Will that work...?

Nothing against eBay now.

But I wouldn't let just anyone reprogram my airbag control unit.

Hi,

"It's a good thing that airbags are classified as explosives, so he's not allowed to sell them. It's unbelievable how much money people make from things like this."

Just the idea of resetting such a control unit after a crash, when other things might have happened to the vehicle's power supply and potentially to the device itself...

I can already guess what's going to happen next... as the next stage of escalation, they'll install a small explosive device in the control unit that will destroy it upon impact, without damaging anything else. That way, those kinds of businesspeople are effectively out of the picture.

Best regards,

January.

Unfortunately, no one knows if he understands his field. But what could possibly happen to the vehicle's electrical system that couldn't be constructively prevented within the safety guidelines (SG) if one wanted to? Unless you reroute a distribution box .
If it were up to me, the car would have to be completely scrapped. It's clear that the airbag is only designed for one use. As for the control unit, I think charging a lot of money for it borders on extortion or promoting the sale of new cars.

@ everyone

Okay, I received the bill for the workshop visit yesterday, and...

For the repair of your airbag control unit, Audi AG has covered 100% of the material costs .

Without any action on my part.
The cost of labor was covered by the used car warranty.

Is it a 2000 Audi A4 Avant 2.5 TDI quattro?
Control unit number: 8D0 959 655 E.

The engine control unit (ECU) was read out using a diagnostic device from Grundmann Messtechnik (or something similar; I need to double-check the exact name) at a local repair shop after the check light remained on during startup.
