mixture adapt not reached, anyone know about this?

[max_s2]

Cleaned connectors of MAF and Lambda. Mixture bla bla and hight boost errors went away, but there are two new in:

00525 - Oxygen Sensor (G39)
29-10 - Short to Ground - Intermittent
00537 - Lambda (Oxygen Sensor) Regulation
08-00 - Control Limit Surpassed

Cleared both faults, drived ~15KM flooring the car (even 220KM/h got out from my baby) and then only one fault apeared:

00525 - Oxygen Sensor (G39)
29-00 - Short to Ground

Lambda dead?

That 29-00 code is fairly clear speaking...

[max_s2]

OK, will change tomorrow. Then I'll post a review

[max_s2]

Changed lambda, cleared codes, went for a drive and nothing changed.. still the same faults after a while

doesnt 'short to ground' mean that there might be an electrical fault of the cables that connect to the lamda?Is everything connected nicely?Maybe there are breaks in the cables that might be doing that.

i occasionally get the intermittent and lamda control as well,but the car usually runs ok.

Mine also runs OK, just fuel consumption is bad.. cant get under 9.5-10l/100km driving normaly and no overboost at all, only 0.9bar. There was only one day in my cars history when I drived ~200KM and avg fuel consumption was ~7.8l/100, cruising constantly 95km/h.
The interesting part is that these faults jumped in my ECU only yesterday after I cleaned lambdas connectors.
Voltage between two pin connector ~13v (should be between 12-14) when engine runing - so its ok. All wires are in good condition and no breaks in two-pin connector. First pin for earth and second one goes to fuse 25.

Update. I let car cool down for a couple hours and then went for making some tests.
Heated car up to its working temp and disconnected lambda at all.. and you know what? There are no faults in ECU at all.. how this could be possible? Or maybe its normal? I start to think that there are some problems in wirings..

Tell me.. for what is the two pin connector and the single one? What they do and are for? As I understant one is for heating lambda and the other one..?

Readed motronic ignition service manual and is says to mesure voltage from lambda wires.
Between two pin connector its 12-14V so its ok.
When I connect my multimetter to the single one and earth it shows me 450mV. There should be 450 +/-50 mV so there is all ok.

And all connected after some time when engine has been running, it shows me up this..

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

..when drived some KM, it also puts in the 00525 fault saying "Short to Ground".

Two pin connector is heating for lambda
Single pin connector is lamdba signal to ecu.

[max_s2]

So.. still got these two damned faults:

00525 - Oxygen Sensor (G39)
29-10 - Short to Ground - Intermittent
00537 - Lambda (Oxygen Sensor) Regulation
08-00 - Control Limit Surpassed

Maybe FPR is causing this problem?
