I'll check, but IIRC voltage at terminals should not drop lower than around 11 volts on engine crank - ideally, prevent engine from starting during test if possible. Do you know if the battery is original?

I'm wondering if your terminology is correct - you say the vehicle 'becomes sluggish when going uphill because the DSG shifts down too quickly" - Do you really mean that the DSG does not shift-down quickly enough?

Hello, multiple fault reports such as you have posted seem to be common with battery issues - have you tested battery while cranking the engine? Another possibility reported on some other postings is crankshaft position sensor fault.

+1 for the 110, not as silky smooth as the 1.4 but a very willing engine. The 6-speed box on the manual version is a bonus.

Had only one been left in? It beggars belief that this block has been in place for 4 years!

@pab567 A question about wife's 2018 Fabia (MY17) it has what I assume is Bolero MIB2 (device 5Q0035842C, HW. H41; SW. 0468.) - is navigation from iPhone only displayed on MIB if connected via USB - or is it possible to connect wirelessly?

That sounds as if they cannot now be trusted - unacceptable that they 'missed' the control unit fault report when they were diagnosing other issues.

Rather surprised that a probably overheating engine was indicating low coolant temperature - suggests that temp sensors may not be located in ideal position.

To avoid any misinterpretation, don't use graphite powder near anything electrical! - it's electrically conductive. Great in locks, but for switches, use a dedicated switch contact cleaner or isopropanol only.

During this long motorway run, what was the oil temperature showing while the coolant gauge was displaying low? Was the coolant level correct before starting the trip?

Pretty sure the Mk3 Fabia power steering is electrically assisted only - no hydraulic operation. To confirm, Google the specifications for your vehicle.

The slipring you say was darker than the other possibly indicates that the associated brush was not making proper contact - there does look to be a considerable amount of wear on both sliprings too. I'd suggest that the old carbon brushes are unserviceable.

Hello, welcome to the forum. I'm pretty sure these infotainment systems are coded to the vehicle - assuming the replacement unit is functional, I believe that at the very least you will need to get this done.

Assumption is for full synthetic oil - American sites are saying ideal oil temperature for TSI's is in the range 110 to 127 C. Over 102 C is great for eliminating any combustion waste products from the oil. I haven't done the conversion from F - but references suggest fully synth oil doesn't start to break-down until well north of 250 F

Hello Tony, welcome to the forum. Sorry to hear about your wife. Did you have to sign a non-disclosure agreement with The Company? 😇

DSG problems can be an issue, particularly in regards to correct servicing, depending on type fitted.

Suggest looking at condition of RH strut damper first. To your knowledge, is this vehicle still at stock ride height? Bump-steer is a normally unavoidable consequence of changes in steering geometry during suspension travel and is not always an undesirable factor - provided it is uniform and predictable.

Although the current tyres fitted may not be ideal, it is highly improbable that matching tyres, whatever the make, will cause the OP's issue with bump-steer in one direction only.

You're ok - G11 is compatible with G13 and G12++. Get engine refilled with G13 or G12++ / G12evo once the leak is fixed. Be aware that the system should really be vacuum-filled with the new coolant to avoid issues with airlocks.

Hi, I think you will be ok with what you've used so far. Wait one and I'll check compatibility and come back.

One problem with that without access to a test track, will be willingness to take it to speeds where this becomes an issue.

One thing to check - is it possible that the LH transit block is still in place? Bump-steer in RH direction only could suggest more suspension movement on the affected side.

Does this 'diving to right' behaviour while travelling at speed present itself all the time - or in curves only? if only in curves, is it only in right curves, I.e. bump oversteer?

Ditch the bag - or replace the expansion vessel for one without it if your present unit has one. There apparently are some later expansion vessels containing a more robust (plastic, tubular) silicate dispenser, but I'd suggest going without the 'teabag' type.

The coolant service life is reported to be shorter without the silicate dispenser, I have just had the coolant changed in the Octavia, after replacing the 'Mit Silicat' expansion tank for one without it 4 years ago.
