Hi folks. My friend asked me to have a look on his seat leon, 1.6 petrol, BSE engine, 1.6 petrol. Car running a bit rough. I've checked everything, seems to be fine, but when strolling through group 08, at 061 found that throtle valve angle is out of range. -19, but have to be between 1 and 3. Any idea does it affect idling and how to get it sorted?

I have done throtle body alignment, and it was OK.

Please post an Auto-Scan for context.

What do you see from the actual sensors in group 060.1 and 060.2?

What happens to the value in 061.3 when you step on the pedal?

car is overfueling. have replaced all sparkplugs, ignition coil, temperature sensor, map sensor, no obvious inlet manifold leaks, pressure in inlet manifold within range, timing physically checked (marking on camshaft pulley and crankshaft pulley), electronically also - all good, Lambda (oxygen) sensor been replaced recently.

sparkplugs wet and looks dirty.

There is an idea that valve guides and/or oil rings on piston have gone, but there is no obvious smoke, however friend said he had top up oil twice in last half year.

Car runs rough, and idle isnt stable, fluctuates 590-670. Oxygen sensor voltage fluctuates within the range.

that throttle angle in negative .. is it closed too much ? as car was in some garage before, friend said them were doing something with throttle box , " adjusting to make car not to conk out at cross lights" .. wonder them did something to throtlebox ?

edit: also replaced fuel, as fuel was with some sort of contamination. ... i think water.
edit2: also did compression test. all figures fine.

61.3 is some sort of regulation/compensation, Range is -40...+40 %
For angle look at MWB 60 and 62.

In my label file I have written the above mentioned.
I have more than 10 log files, here are a few:
61,640 /min,Omdr.,13.74 V,Volt,-20.3 %,Lambda, 0000,Bin. bits,
61,864 /min,Omdr.,13.94 V,Volt,-13.3 %,Lambda, 0101,Bin. Bits,
61,1536 /min,Omdr.,13.94 V,Volt,-23.4 %,Lambda, 0000,Bin. bits,
61,640 /min,Omdr.,13.74 V,Volt,-20.3 %,Lambda, 0000,Bin. bits,
;-24.2 %,Lambda,
;-18.8 %,Lambda,
61,0 /min,RPM,11.11 V,Voltage,0.0 %,Lambda, 0000,Bin. Bits,

Ok. Thanks.

But still have to find the reason why that car overfueling. I am not really good on vcds, might somebody would point what is the way to figure out what's goin on with that car?

Thanks.

Can anyone suggest which group to watch how operates lambda (oxigen) sensor?

Thanks

Sounds like somebody made a mistake in that label file. It happens.
That'd be me. ;) I looked into this and this is supposed to be throttle valve actuation but as Niels already stated, it looks more like a correction/compensation value. The 06A-906-033-* controllers are not very compliant, when it comes to obeying the VW standards for measuring values. I've clarified this in our description, but honestly the documentation for this ECM from VAG is lacking. *sigh*

Standard groups (30+) should apply.
