AZD engine (1.6 16V petrol) - EGR basic settings cannot be performed (adaptation error every time)

[crok]

Hi Community!


You are my last and only hope I think..

I have a Seat Toledo (2002) with an AZD engine
(1.6 16V petrol, same as in Golfs and Boras).

My EGR valve was faulty and has been replaced with a new one
but I cannot adapt the (brand new..) EGR valve, it always fails,
says "ERROR" when I try to adapt it in VAG-COM and I have the
following code in the ECU:

17812 - EGR System: Basic Setting not Performed
P1404 - 35-00

Voltage is 12.4V, coolant is around 40°C (did not start the engine yet).
No electrical consumers are on during adaptation process
(headlight, window defogger, et cetera)..

When I do the adaptation I do hear and feel the clicking of the valve.
When I do an output test I do hear and feel the clicking of the valve.

I'm using VAG-COM 409.1 full version (yes, it's old ..)
but I tried it with VCDS and AutoCOM as well - no joy.

Is there any trick to do the adaptation? What can be the issue?


Regards and thank you for your answers in advance!

Any idea, girls and guys? No hope? Come on..!

Which adaptation value are you using?

Which adaptation value are you using?

I used the Ross-Tech instructions (Meas. Block 074).
Exhaust Gas Recirculation (EGR) Valve Adaptation - Ross-Tech Wiki

..or what do you mean by adaptation value?

[Crasher]

It is Basic settings 074, not measuring blocks. When “ADP OK” is shown in Basic Settings 074 Zone 4, start the engine and go to Basic Settings 075, give the engine 5 short bursts of revs to the max and the value in Zone 4 should change to “Test ON” and then let it idle until it says “SYS OK” but sometimes it is necessary to do this test on the road with the engine on trailing throttle in a high gear.

..and here comes my issue: no matter how and how many times I try to do the adaptation in basic settings (channel 074) it always saying "FAIL" - so this is my issue.

This is what I got:
ECU: 036 906 034 CP
MARELLI 4MV 4376
Coding: 00031 <- what is this mean?


..and 2 faults codes:
17812 - EGR System: Basic Setting not Performed
P1404 - 35-00 - -
17847 - Potentiometer for EGR (G212): Error in Basic Setting
P1439 - 35-10 - - - Intermittent

I discovered that cruise control was active and the car has no cruise control - thus I disabled it.
(There was a G in the name of the ECU like MARELLI 4MV G 4376)

[Crasher]

The G stands for “Geschwindigkeitsregelanlage".

There seems to be some conflicting info on ELSA in EGR valve testing it says adaptation is in measuring value block 075 and in readiness code it says basic settings 075 for testing and in measuring block analysis it says adaption is in basic settings 074. I use basic settings 074 for adaption and 075 for testing. Try going into Adaptation 10 group 00 read, save yes and do this three times and then try again. Be warned though that I have known these engines go nuts after this and start saying the MAP sensor is faulty. Usually cleaning the throttle body and doing basic settings 060 a few times gets them back to normal. Check you have ignition live power on the black/white wire to pin 1. Which make and part number of EGR valve did you use?

[crok]

I just got in from outside.. no luck..

I reseted (did the Adaptation [10] > Group 00 > Read and Save) the ECU several times (n+1 n>5) and then adapted the throttle body (Basic settings > Group 060) without issues BUT Basic settings > Group 074 always failing.. ADP RUN and always FAIL.. I've checked the black/white (PIN1) and yes, I see voltage. The manufacturer of the EGR valve is SIDAT, the part nr. is 83.649 S.I.D.A.T. S.p.A.

[Crasher]

The genuine number of the valve for a 2002 model year Toledo AZD is 036 131 503 T, the SIDAT 83.649 (the same as their alternative make 83.649UE) is the equivalent of the VW part number 036 131 503 M which is for the AZD from 1999>2001. SIDAT buy these from other manufactures and offer them in three versions, 83.4627, 83.627UE (earlier non finned composite body designs) and 83.627 which is of the revised style, so IS your car a 2001 or a 2002? PM me your Vehicle ID number.
