Yep, that's the trouble with the myriad of cheap scanners like OBDLinkMX+ and Carista etc. They sell you on "All 1996 on OBD2 cars supported" but that's misleading because the only standard thing about OBD is the port! As Dan says, VAG have a lot of brand specific data PIDs 90% of cheap code readers can't display.
As clunky, slow and outdated as VCDS is, it's the only option for VAG enthusiasts looking to get balls deep into diagnostics......unless you want to spend a few grand on a Snap-on Verus Pro!
Anyway, flaps. Everyone loves flaps and flapjacks! I agree they should be binned off. No one wants the extra complication and expense, but unfortunately some engines don't like having their flapjacks eaten....especially on a frosty morning eh
@muff1991 ?
Something strange going on with your flaps muff, and 'calculated' engine load seems a bit high to me! At idle, the flap position should be 99.6% i.e. fully closed.
Go for a drive from cold and get engine coolant, rpm, throttle angle and channel 143-3 (flap position) up on your screen. VCDS mobile via the HEX-NET interface is really handy for this as I stick my phone in front of the cluster for easy viewing.
Anyway, the flapjack behaviour is as follows:
Cold to 50 deg (iirc) water temp = flaps at 99.6% (fully closed) most of the time except heavy throttle.
50+ water temp = 99.6% at idle and cruising. When touching the gas, the flaps should go from 99.6% to 0.0% (fully open) pretty quickly. When backing off, the flaps should close progressively from 0.0 to 99.6. It's not a simple on/off and it's not rpm dependant either. The flaps can be closed cruising along at 80!
BTW, 'fully closed' doesn't mean blocking the port, it means maximum tumble effect. Air will always get past the flaps regardless......but if they are closed when they should be at 0.0%, you will notice a lack of power and/or very laggy torque delivery.
My Flap B1 positions are 0.00V and 1.450V by the way.....and they never move from that.....but the % position moves a lot!
