What proof has the garage given that this alleged spillage caused the 12 volt charging issue?

Repair completed, picked up Fabia this morning. Fault was P334B00 - charge pressure actuator, mechanical malfunction. SWMBO is very pleased to have her car back. The cause of the fault was found to be excessive resistance to movement of the turbo boost flap control arm. The part replaced was Turbo actuator coupling rod, repair kit 04C-198-701-D.

Well done for finding that, I couldn't find it after a pretty wide search!

Hello, welcome to the forum. I'd read that symbol as side airbag deactivated, but will check online.

On RHD roads, the camber will normally make a vehicle pull slightly to the left - assuming OP is RHD, he says vehicle now pulls right.

Damage to the NSF (unless a simple case of 'kerb rash') wheel suggests a strong contact with something - especially regarding the reference to heat and a lump hammer! Almost certainly this could have affected the steering geometry, which is supported by your comment about the steering not being centred - was it centred before you noticed the change in ride quality and/or damage to the wheel?

The 11.9 volts standing voltage is low, but could possibly be because some of the modules have not gone into sleep mode yet - the standing reading can be unreliable unless taken at least 20-30 minutes after the vehicle has been fully shut down. However, it's very likely that your battery is faulty - which can be confirmed with a full battery test.

I'm pretty sure that the front assist being unavailable is not a MOT critical failure - as it can be deactivated by the driver. Apart from a few occasions where mine has thrown a brief warning where there was no real risk of a collision - usually when I was overtaking a vehicle that was turning-off to the left in front of me - I've found the system pretty reliable.

Is the sensor wiring ok? in the second image you have attached, it looks a little odd.

The front radar doesn't affect the steering - just the proximity warning and, eventually, the full ABS avoidance braking. If fitted, lane assist steering intervention is monitored by the front (A5 ?) camera.

It does appear that your mount is broken, most likely that the grill has been nudged in a parking manoeuvre, deflecting it sufficiently to push the sensor back. I would think it's possible to confirm the radar sensor functionality with VCDS, but certainly worth replacing the mount and getting the calibration checked.

Hello JL, welcome to the forum. There should not be any movement in the radar sensor, check that the mounts haven't been damaged or broken. Hopefully the sensor will be undamaged if it's just been displaced in a parking bump. Radar will almost certainly require recalibration if the mounts are replaced.

Possibly something as simple as a battery connector not correctly tightened when the battery was replaced in January.

Very likely that there is a problem with either the battery or, possibly, the alternator charge rate - my money would be on failing battery. Battery disconnection is highly improbable to improve the issue - but will not affect any settings, there will likely be several transient faults indicated when the battery is reconnected, which will all clear after a short drive and turning the steering from lock to lock. Do you do a lot of short runs? How old is the battery?

Do you also get the option of the Aisin 8 speed TC gearbox in Aus?

Is this a Mk4 hybrid? Multiple and seemingly random faults like that can be a symptom of low 12V battery levels on the MK3 - and there have been a number of Mk4 owners reporting issues with 12V battery charging.

👍What is your new car?

IIRC, relative boost should be around 1.5bar (22psi)

Received an update call from the garage this morning, turbo flap actuator is OK - the issue is sticky/tight actuator arm. A repair kit is available and has been ordered (£40) - no information available if the kit is a revision, but a possibility.

Gidday, welcome to the forum. How's the weather down there?

It sounds like you have 'keyless start' - Not full KESSY (keyless entry and start)

Update 3, Fabia into garage this morning. When I scanned for faults last week, there was just one DTC - P003A, garage called me to say the DTC now recorded is P334B00 - Charge pressure actuator position sensor - which fault appears to be fairly widely reported and, I understand, there has been a TPI issued by VAG. Waiting on results of further investigation.

That engine appears to be misfiring fairly badly, have the spark plugs and coil packs been tested?

Hmmm, looks like Op has disappeared. I'd think that this feature would require the complete set of sensors to work - unlikely to be present if PP not originally installed from factory.

For RHD vehicle, I believe that the window switch has to be set to left (L) for the mirror to dip while reversing - you also require electrically operated seats for mirror to dip to correct position, otherwise mirror position while reversing can be a little random.
