Help with speedo and misfire

[Slanu]

Hey,

My speedo stopped working the other day everytime i stopped the car for a few minutes. It would turn back on after a few hours. It's now fully not working and get the p0501 code. Sensor A. Where is this located?

I had a slight misfire. Changed the camshaft sensor which seemed to fix it.

My airmass sensor was also causing the engine to conk out if it moved so just replaced it and now the fuel gage is moving wildly on its own and im getting more of a misfire! Any ideas? All responses appreciated

What are you using to scan the car? The cheap ones don't pick up the faults properly you would be best to get it scanned with vag-com and maybe some logs to pin point the misfire.

Using vsds from vag com, the misfire is fixed! Disconnected the battery now after fitting the airmass and all seems to be good.

What do i need to do to fix the speedo and fuel sensor? Revs guage working

There is an issue with the speed sensor located in the gearbox... implausible signal suggests the sensor could be faulty
