VAG-Com more codes!

[Jamo]

Got myself a full version of Vag-com ( reckoned i'll be need it - allot! )

Pulled more codes from the car and up popped these babies:

00-00 - - 00561 - Mixture Adaptation 13-00 - Adaptation Limit (Mul) Not Reached

00537 - Lambda (Oxygen Sensor) Regulation 08-10 - Control Limit Surpassed - Intermittent

00519 - Intake Manifold Pressure Sensor (G71) 07-10 - Signal too Low - Intermittent Readiness

Anybody point me in the right direction? Is the G70 the MAF?

Taken from s2central.net

00561 2413 Mixture Adjustment
- Adaptation limit (mul) exceeded
- Adaptation limit (mul) not reached
Adaptation limit (add) exceeded
- Adaptation limit (add) not reached
Fuel pressure too low
Ignition system faulty
Leakage in exhaust system before catalyst
Incorrect signal from G70
Increased fuel consumption
Sooty exhaust
Check fuel system & pressure
Check exhaust system for leakage
Check G70

00537 2341 Lambda sensor control
- Maximum control limit exceeded
- Minimum control limit exceeded
Low fuel pressure (<3.3 bar)
Ignition system faulty
Intake air leak after G70
Leak in exhaust prior to catalyst
G39 faulty
Fuel pressure too high (> 4 bar)
CO before catalyst less than 0.5%
High fuel consumption
Rich exhaust
Fouled spark plugs
CO before catalyst greater than 3%
Check fuel pressure
Repair air leak
Check G39
Check fuel pressure

00519 2222 Manifold Absolute Pressure Sensor, G71
- Signal too low
- Signal too high
- Control difference
Vacuum line between inlet manifold and J220 pinched, plugged or constricted/bent
Fluid separator in tube from inlet manifold to J220 full of water
Wastegate faulty
Wastegate frequency valve faulty
MAP sensor in J220 faulty
Turbocharger faulty
Loss of power
Check vacuum tube and fluid separator
Check wastegate and frequency valve
Check turbocharger

Ah penny drops on the 3rd code! There's no boost line connected to my ECU!

Bet if i connect one up it will get rid of one of the codes

[4WheelDrifter]

It's about time that boost controller went in the bin, along with that water injection system.

[Jamo]

Water injection system is being removed. Boost control stays!!!

I was just about to point out that you don't have a completely standard Motronic setup, so don't be surprised by errant fault codes!

If you go the modified route, be prepared to live with the pain!

It should run rubbish with the MAP sensor disconnected

My car has an electronic boost controller and boost isn't controlled by the ECU

Anybody got any thoughts on the other 2 codes?

[twoqu]

Yep, but surely your motronic needs a vac/boost signal to the map sensor unless it has an external map sensor that feed the signal electronically back to the ecu!

Why? the MAP doesn't effect the ignition system it's seperate code.

This thread isn't about that anyhow can anybody point my in a direction over the other 2 codes.

[newsh]

So ignition timing doesn't change with vacuum and boost, I'm amazed!

How old is your Lamda sensor?

Leak near the MAF?

[waad_uk]

Well, the only thing that seems to be common between the top 2 codes is pointing towards an exhaust leak.

Hi Jamo,
My ****** puts that 00561 up.
So i'm most interested as to what gets posted!
I can only think its a maf **** up. cleaned my maf and goes better (had missfire when boost kicked in) no missfire now so i've not been back on with the com. I do think its had the 561 since i bought 6000 miles ago....

i

Mine won't go away either

replaced Lambada

cleaned MAF in IPA for 48hrs

no exhaust leak

no leak after MAF

mines 00561 not reached (mul) intermittent

IT'S GETTING ON MY NERVES NOW !!!!!!

Runs fine though just sooty plugs/exhaust and 80 miles per £20 worth of Vmax round town

I've ordered a new Lambda probe from GSF so will fit that, going to pressure test it once again

Just read my way through this post, (bit behind I know ), Over the last 5 years, I've always logged 3 errors

65535 (checksum error cause Mr. Nothelle wasn't too worried about hiding his work)

Two old favourites:-

537 -Lambda
08-10 Control Limit Surpassed - Intermittent
or
11-10 Control Limit Not Reached - Intermittent

561 - Mixture Adaption
14-00 Adaption Limit (Add) Exceeded
or
12-10 Adaption Limit (Mul) Exceeded


When the turbo retired a few years ago the Lambda got soaked with oil , cleaned it up at the time, and due to fuel consumption & performance I'm guessing it's still ok, but interested if others got rid of problem/s with lambda swap ?

The exhaust system (standard) was removed, rebuilt and reinstalled when I did the clutch 2 years ago, no obvious leaks or holes in the system to contribute towards above errors.

Again would be interested if/when people diagnose these errors...
