The reason I ask is that there is a coolant thermostat for the gearbox in DSG equipped cars which is almost always found to be the cause of lower than ideal engine coolant temperature when it fails. Lots of threads about it in lots of the subforums.

I reported a couple of their first posts just thinking it was spam, but then noticed the pattern.

@J.R. you appear to have a weird stalker.
-
Is it a DSG gearbox?

If you open up the BCM, you may see physical damage/ burning on that chip.
-
With the connector unplugged from BCM, measure resistance to earth from the pin 16 wire. It should be quite a small resistance, because all three indicator bulbs on the left side are in parallel from it to earth, and the front and rear bulbs are 21 Watt, so their cold resistance will be a very small number. If you measure a high resistance instead, it could suggest a wire breakage/damage/corrosion from pin 16 towards the bulbs (black/white) wire.
-
Pin 15 of that connector, a red/white wire is the power from fuse 49. But it also supplies the right side indicators, so if they work, the power feed into the BCM must be OK.
-
Yes, pin 16 should alternate between 0V and 12V if the chip is working the left indicators. Fuse 49 carries current into the chip on pin 15 of that connector (or maybe 13, I forget), the MOSFET transistors in the chip should send it back out when indication is commanded.

Wideband sensors are not easy to test, I believe. Try replacement. Do you want a part number?
-
What problem are you actually trying to solve?
-
Lower arm balljoint part numbers for your VIN are 1K0407365C for the left, and 1K0407366C for the right side. Parts catalogue doesn't give a dimension for the taper.
-
Between the heater pins is probably a few Ohms, but may vary with temperature so try with cold system. I don't think any other meaningful measurement can be done on the sensor part.
-
The wiring info for electromechanical power steering from July 2018 onwards shows only one fuse, an 80 Amp under-bonnet one - SA3. If that had failed you would have zero steering assistance.
-
There's probably a way to test the injector loom for major problems from the connector on the end of the head. Resistance measurement between pairs of pin contacts. Haven't looked into this, but I bet there's info out there.
-
Bypass the cooler so that no coolant runs through it; see if coolant loss ceases. Can't offer detailed practical guidance on how to do it, but it probably involves a little plumbing ingenuity.
-
@JamieH86I've woken up this morning with another thought about this. The problem with the misfiring cylinder could be a problem with the injector loom, rather than the injector? Might be good to check that before spending lots on refurbished injectors and fitting? Or even something mechanical like a hydraulic lifter (tappet)?
-
Give it a try then. Nothing to lose.
-
If the chain has jumped a tooth somewhere you really don't want to be trying to start it. But if that has happened, any damage was probably done straight away as soon as it jumped. Did the problem occur at start-up, or while driving? What symptoms were there?
-
I'd be checking the chain timing if it was mine. (Crankshaft/camshaft correlation problem).
-
P0058 appears to be an oxygen sensor code in my Google?
-
This ebay listing for a cgpa inlet manifold shows the position, on the opposite end of the manifold to the throttle body. https://www.ebay.co.uk/itm/304414591091 Second from last pic even shows the screws and part numbers.
-
Hatboy Harvey has a 1.9TDI doesn't he? His MAP sensor is going to be different and in a different place than on a 1.2 petrol. Held in by 1 or two screws at most on yours I should think, might well be standard Torx screw yes. What makes you think it needs replacing? They almost never do on your engine type.
-
Oil level sensor and QI6 servicing code at delivery both confirmed.
-
I think they stopped supplying stickers with car details about 5 or 6 years back. Will read/reply to your message shortly. Just sat down to eat.
