Hello everyone!

Adapter: AI USB without CAN (intelligent).

Symptoms:

Power loss (specifically, lack of torque at low speeds).
Maximum speed not reachable.
Fuel consumption: 9 to 10 liters per 100 kilometers, regardless of driving style.


Maybe you have some ideas!

Georg.

I would say this is a communication problem, and we can already see that because an engine control unit (ECU) from this year simply wouldn't have space to store 87 error codes.

What specific interface are you using? Is it the AI MultiScan USB? Is the latest firmware installed on the interface? Auto-Intern hardware requires separate software for firmware updates; this process does not run through the VAG-COM internal routines. It would also be interesting to try reading the data with a HEX interface; I'm going to venture a guess that this issue wouldn't occur with that type of interface. Where do you live? What is your postal code area?

I live in Austria! (Specifically, in Carinthia / East Tyrol / Salzburg)!

Incidentally, this alleged communication error only occurred once.

Adapter: AI MultiScan USB (VAGCOM + dongle function) with the latest firmware.

By the way, I once had a problem with communication where the ÖAMTC (Austrian Automobile Touring and Automobile Club) tried to access the engine control unit (ECU) using three different devices (2 Gutmann, 1 Bosch) – and they were unsuccessful, even though the Bosch device had previously worked!

The errors that were read out using the Bosch and AI adapters are always the same, with only one exception.

Code:

01242 - Output Stages in Control Module
            06-10 - Signal too High - Intermittent
00000 - End of Output
            00-00 -  -
00000 - End of Output
            00-00 -  -
00000 - End of Output
            00-00 -  -
00000 - End of Output
            00-00 -  -



    where the error code 00000 is not documented anywhere and appears repeatedly in the error memory, regardless of the diagnostic tool used.
    But maybe it's not even an error, but rather an EOF marker or something!

    "While error code 01242 is documented, it is not associated with the 'subgroup' 06 - Signal too High, even in the latest original Audi repair manual 'Diesel Direct Injection and Glow Plug System > 02.94', edition 05.97."


I have already performed diagnostics on the actuators, and everything is working except for the exhaust gas recirculation (EGR) system. I'm not sure yet whether it's functioning correctly or not, as the membrane in the valve is damaged, and the EGR system itself is also clogged.

"The turbocharger is producing full boost pressure, but it's building up very late. I've already tested the hoses for leaks."

The LMM (likely referring to a mass airflow sensor) is providing a good signal, as measured by the voltmeter, ranging from 0.xxx to 5.xxx volts.

I hope to be able to check the remaining items (MWB 0, individual measurements, exhaust gas recirculation control) this weekend.

The errors listed in that very long list are almost certainly not real. There's some kind of problem, either between the car and the interface, or between the interface and VAG-COM.

You should get in touch with Auto-Intern.

You can also try the standard English version 607.3 from our download page and let us know if you experience the same problem.
