Fault code 65535 / blink 1111

[A80Avant]

jade,
empty your pm folder

[jade]

could it be that your ECU doesnt like CT? haha

Possibly

In general the car seems to run well considering it has not been mapped

I would like to go with the vems but i should be sure all is well, before & if i go that way

Nope - that doesn't have anything related...

MMMM car seems to run ok do not really know where to go with this, re check earth's

Or map failure ??? or would that be 2222

faulty ECU ???

Mmmm - thats normally the cause of 65535 - that or certain MAP failures inside...

Map was fine before strange if it's just given up now

I am presently running on a comp ct 458 with the old chips, would this do it ???

Has the ECU been remapped already ?

If so - there is a good chance that a bad checksum is throwing up this fault code...

No car has not been mapped yet, Hoping to do that soon

I Have finlly got rid of most of my fault codes

Today when i pulled the codes I got 65535 / 1111 & 4444 which is no faults to show that was first then followed by 1111

I have tested the pins on ecu 10 14 19 24 seems to earth well, because of my Furans i had to change the location of earths one is on the cam cover & the other is on the last inlet manifold bolt firmly done up.

Any ideas please on this, because i am keen to remap but need to get to the bottom of these fault codes first.

Thanks Wayne

What voltage should they have when its at WOT?

PIN 2 - 3 + 4.6v full throttle

Ok TPS have 5v on 1&2 2&3 have 3.6 going out' So this hopefully is the problem change switch

00519 is : internal ECU pressure sensor fault

00519 - VAG1551/2 Fault Code Number
ECU Internal Pressure sensor (G71)
Pressure sensor defective,
Repair or replace ECU or replace internal pressure sensor

00519 Manifold Absolute Pressure Sensor

- Signal too low

- Signal too high

- Control difference


00518 has to do with TPS. is that wired properly?

g71 would be the map sensor strange it worked fine before i will double check all vac lines

I have 5v at the TPS resistant looks ok

But i did just measure 3.8 with throttle fully open on pins 2 & 3 that could be the problem there i will double check this.

Thanks for your input
