Hello again ddilenger,
Just to give you some additional information to the previous post, in case you need. Probably you already know most or all of them, but I will give as much information as I can.
Driving the car I noticed a few hickups during accelerations and mid RPMs. I guess it can be due to the ECU "thinking" there are O2 sensors after the catalyst (or maybe just due to the typical bad gasoline/alcohol mixture). The hickup is very similar to the ones I was having with the original BIN and got (real) lean codes.
Just after clearing the codes, the O2 readings go to around 12%, this happened with the original BIN also, and it gets near 0 after driving. Probably the ECU gets adapted to the "cocktail" used in Brazil.
I thought the idle was smoother.
After driving a lot today, the CEL finally came on due to the missing O2 sensors after the catalyst (not installed by Audi in my car). The codes were thrown yesterday, but the CEL came on after a few engine starts (normal, I think), and it now stays on as I didn't clear the codes. So the CEL is working as it should and it just came on because the ECU "thinks" my car has O2 sensors after catalyst.
Also, now the O2 DTCs appear in the OBD2 page as they should. The brake boost one does not appear though (not emissions related).
Sometime ago, I asked Ross-tech about my original ECU coding and they replied that my car is "European Union without secondary air induction (MVEG II)" The software coding is still there: 04551. So, I think my car does not have the "Secondary air system monitoring".
I don't think it has the heated catalysts also. There is no wiring in them.
I never located the EGR valve in this car, but I saw the part in Ebay and seems to be vacuum operated, so I guess it is not monitored anyway.
The readiness status didn't change since yesterday:
Mode 01 - PID 01 : Readiness -- Address 10
Number of DTCs stored: 2 -- MIL Status: MIL ON
Misfire monitoring: Passed
Fuel System: Passed
Comprehensive Components: Passed
Catalyst monitoring: Failed or Incomplete
Heated catalyst monitoring: Not installed.
Evaporative system monitoring: Passed
Secondary air system monitoring: Failed or Incomplete
A/C system refrigerant monitoring: Not installed.
Oxygen sensor monitoring: Failed or Incomplete
Oxygen sensor heater monitoring: Failed or Incomplete
Exhaust Gas Recirculation: Not installed.
Thanks again a lot! Thanks to you, I am very close to solving that issue!
Regards,
|

I will try to take a look shortly, digging through the codewords is a pain. How soon after you flash do the 02 codes appear? If they come up immediately it won't be TOO bad. Still the same 3 codes?

Hello,
I believe when you say it is a pain. I tried to do that and got confused from start to end.
From what I researched, my APS engine was not equipped with the same features as some newer 2.4 engines. But I think getting a working "ready" file will be rare as this engine is not available in the USA.
I guess I have bad news... I cleared the codes to double check, and:
From the original 6 codes that appeared immediatelly, only one remained after you modified the BIN. This one still appears immediatelly:
18320 - Pressure Sensor for Brake Boost (G294)
P1912 - 35-00 - Short to Plus
The other two take some time to appear. I have to drive the car and it appears after a few miles. The CEL lights after several miles though:
16524 - Oxygen (Lambda) Sensor B1 S2
P0140 - 35-00 - No Activity
16544 - Oxygen (Lambda) Sensor B2 S2
P0160 - 35-00 - No Activity
Thanks again for helping.
Igor

As I said before, you file is 100% OEM, untouched in any part... I´ve compared to another I have here.
For some reasons car makers deactive some kind of DTC from going MIL on, for example Lambda probes usually don´t make CEL on, except when they are post catalist.
Temperature sensors are another kind of sensor that can be dead and don´t make CEL going on.
MAF usually makes CEL going ON, but ECU take some time to make sure it´s really defective

Hi Overspeed,
I believe you - my file is 100% OEM.
I can´t be sure why, but I suppose Audi did the "emissions delete" for countries with lenient emissions requirements. Specially in Brazil with the gasoline/ethanol mixture. Many customers were probably complaining about a lit CEL and they "solved" the issue. Deactivated the CEL forever. I saw at least 3 A4s with the same situation here. Including two 2002 3.0 30v.
According to the OBDII requirements, the CEL should light up with all emissions related issues, includind pre-cat O2 sensors. Brazil is still leninent. Back in 2001 the emissions law was extremely lenient and didn´t require the CEL.
Mine never worked. Even with several codes on it and engine stumbling and stalling. It must do the autotest ddilenger mentioned also. Mine never did. Did yours? Was your file retrieved from a Brazillian A4?
Hi ddilenger,
Not sure if this helps or not:
3B0907552L / ECU for 99-00 2.4 APS engines (don´t know the difference to mine)
3B0907552AD / ECU for early 01 2.4 APS engines (mine - DBW and ASR, no ESP)
3B0907552AN - replaced by 3B0997553X / ECU for late 01 (until 05 if I am not mistaken) with additional emissions equipment 2.4 APS engine (the one you´re working on).
Thanks!
Igor,

This should sort out the no rear 02's, and the brake code while keeping the engine light active.  |

Hello Daz,
I am still testing the new file, but seems that this file is perfect!
The CEL turns on when ignition is turned on, stays on, and goes off after engine starts.
The CEL goes on if an O2 sensor is disconnected. It takes some time after the fault is thrown but it turns on as it should.
The emissions test appear with some items as failed after resetting the codes, but it appears as passed after some miles.
Thanks, thanks, thanks!
Igor,

Yes, Daz did an awesome job!
Car runs fine, specially after some adjustments on the adaptation channels to compensate for the low octane gasoline/alcohol mixture used in Brazil.
No more codes and CEL is working as it should.
Thanks again!

Hi guys,
I have an extra question, but didn't think a new thread was needed for this.
I observed that my ECU doesn't have any kind of rubber seal, nor silicon glue.
It is inside a box with rubber seal and there were no signs of water or humidity in the ECU.
I found some pics in the internet and seems that some modules have the seal.
Is mine missing the seal? Can I trust the ECU box seal?
Audi A4 B5.5 2.4 30v 2001 / Bosch ME7.1 (more details at the beggining of this post).
Regards,
Igor,

I think as long as your drains aren't clogged (right by the battery) you won't have an issue.. Just remember to set the E brake when parked on the boat launch..

Hi Jacks!
I use another car at the boat ramp. But I will try not to wash the entire car inside the river!
