Re: Skoda Fabia Lin communication issues

I finally found the issue with this car. Turns out the OE wiring diagram is wrong. I found a different car with the same multifunction switch, in its wiring diagram pins 1 and 3 are swapped around. I wired the Fabia this way and now it works. With the pins connected wrong the switch isn`t grounded a...

Re: Skoda Fabia Lin communication issues

I`ve load tested the power and ground, it`s ok. I even provided the switch with a power and ground straight from the battery and connected the Lin wire at a different place in the network (window motor) to rule out any possible wiring issues. The problem stays the same. When I connect the steering w...

Re: Picoscope 4425-030 wont connect to laptop

Hi Steve, I`m using the generic PS7 software. Version: 7.0.116.13985 There`s no message when connecting the scope, only the dong you get when you connect a USB device. I also tried the Pico for VAS software version: 7.0.116.1374. It does the same thing. I changed the USB settings according to this t...

Re: 2018 Audi RS3 high fuel pressure dropping out

I`ve used this topic to decode the SENT signal from the HP rail sensor: https://www.picoauto.com/support/viewtopic.php?p=102933#p102933 You can see the pressure dropping around packet 40 Railpressure.PNG I`ve placed the left ruler around packet 40 in the waveform, you can see the double actuation of...

Nissan QQ 1.3 petrol, HR13DDT engine. Fuel rail pressure/HP pump regulator current during acceleration/deceleration. Double pulses regulator control at low speed/load.
At low pressure / flow it would make sense to close the valve during the intake stroke of the HP pump.

Re: 2018 Audi RS3 high fuel pressure dropping out

When the air/fuel mixture enrichment goes beyond flammability point, combustion no longer takes place in cylinder which becomes an air pump. The whole amount of O2 which should have been used in fuel oxidation will pass by upstream A/F ratio sensor(together with fuel vapor) whose signal will show a...
