I have a nighmare with Vw Polo

03E906023D

POLO 1.2
SIMOS 9.1
HW04
9510
61H04
5WP40502 04
FST 17/01/07
R405 0657

Car sometimes detect cylinder misfires ( every 20km) but car runs very good.

Problem is with Dtc On car deactivate this cilinder, till you erase it or till stop the car to reset ecu.

It is a nighmare

Car is test compression 100& ok, coils ok, inyectors ok and even have tested with other Ecu.

So I suspect mechanical problem, but car runs good and dont want to waste more time.

I want delete if possible:

P0201 P0202 P0203
P0301 P0302 P0303

Both misfires ( inyector/ coil)

Car is running very good but as I said sometimes....

It is my responsability.

I know deleting errors should not be the solution, but this time is a nighmare for me.

This time I want car cannot come here with any misfire related error.

File is full read bootmode galletto v54 as I read it need complete to erase tables...

If you think it is easier remove all Dtcs... do it.

Thanks beforehand

Thanks for help

I assume car is the problem ( mechanical problem)

But question is:

Why with other Ecu ( and of course other sw) it doesnt detect any misfire????

Donor Ecu is not the same reference as Original but same engine.!!! And exactly same hardware

Car runs without misfires with it!! ONly problem is this error:

17834 Evap purge valve P1426 - 009

It is the only error showed.

I really dont KNow why with original flash is misfiring and with Fabia Donor Ecu doesnt misfire. Suposse must be any difference in the "way Ecu is monitoring misfires " and this is why with this other Ecu it doesnt misfire.

I am thinking perhaps my solution is to remove this only error to avoid repair engine at this moment.



bobolin4o (http://www.digital-kaos.co.uk/forums/member.php/150906-bobolin4o), Could you please make for me again in this other flash and remove only DTC above ( 17834 p1426)?? Dont need to remove misfire on these, as it doesnt detect it...


I really dont have idea of dtc structure in this Ecu.
Sorry for disturb ;)

INfo from this Ecu/ flash is:
03D906023N

FABIA 1.2 CHF
SIMOS 9.1
HW04
CHFA 5418
5WP40851 04

Here you go...
You will have a P0000, but the MIL must be off.
