Check the bulb holder yourself as I’m working of a photo but yes they should both have good earths if that’s how the system is intended. This will because your cars computer will be working from resistance readings to determine if a bulb is blown or not so if it’s using one earth instead of two then the readings might be to high, so when the ecu detects a possible blown bulb it cuts the voltage to it, hence why it tries again when you restart the engine

Me and my Audi clutch are not friends, back story is the clutch friction plate exploded taking out several hydraulic lines, new clutch/ pressure plate, concentric cyclinder and new hydraulic pipe fitted, gearbox removed again for seal to be fitted into concentric slave cyclinder that Audi don’t fit into replacement part and took 3 days to even find in there system, all good for a few months then master cyclinder failed, 14 months later clutch delay valve leaking and master cyclinder won’t bleed due to check valve fault which is a design fault in these master cyclinders, I’m looking for info on the cable that bypasses the clutch delay valve a few members have fitted or even better a braided line from master to slave cyclinder

Vw golf mk7 /7.5 suffer with blocked heater cores and it’s caused by a additive bag that be built into the coolant reservoir bottle that bursts and clogs the heater matrix, common fix was to disconnect the 2 coolant pipes that go thru the bulk head and use a power wash in one hose to push the blockage back out the other pipe, takes abit of time but easier and cheaper then replacing the matrix radiator, hope this maybe of help

I coded this in but using a totally different method to both you have mentioned, I had to code in lane assist first to get my high beam assist to work. Hope that helps

Il shed my insight on these sensors as I deal with vehicle electronics a lot. The sensor on the servo is more of a safety device that has been used for years and often puts faults in stop/start systems and cruise controls systems, the restricted brake performance is the vehicles ecu reducing the limits of the abs pump/ module. It is worth buying a new sensor from the likes of eBay and fitting yourself. No coding required and system will reset after a certain amount of driving, sensor replacement will not involve any fluid loss so is a DIY job

Is the other bulb in the holder working correctly, if your yellow arrow point to what il call pin 1 then pin 3 also looks like a earth connection by the circuit layout
