Hello Tom, welcome to the forum. Have you checked the battery terminal voltage while the engine is running? Does your vehicle have Stop/Start? If so, was the new battery adapted (coded) into the vehicles BCM?

Are you sure you have connected to a permanent 12V supply - rather than one that is only live while ignition is off?

AFAIK, there would be only very slight differences (if any) in fuel consumption between the Manual and DSG boxes - as the DSG is really an automated manual gearbox.

Hello Danny, welcome to the forum. With the 2.0 TSI, be aware of possible issues with earlier versions of the EA888 engine - provided you are looking at versions after around 2014, these were (I think) mostly addressed. The 1.4TSI, manual 6-speed is great - you can expect around 50MPG on a decent run easily - and around 40MPG even with fairly short trips without any hypermiling. That said, I wouldn't say no to a 245TSI😄

Are you certain that the Webasto heater is permitted to operate while the engine is running?

Even a full-on VCDS doesn't cost 'Thousands'!

^^^ This. A very good idea for all modern vehicles. A good OBD II reader will probably cost less than just one diagnostic session. Unfortunately, even very good independent garages will probably not accept an owners claim of faults present without carrying out their own checks - but it's at least a starting point for investigation.

Hello, welcome to the forum. A suitable replacement label should be available from a Skoda parts counter - I had to get one for my Octavia after a panel repair a few years back. Not expensive.

De-ionised water is fine to mix coolant to required strength - but I'd not recommend using it for top up unless in an emergency - and changed for correct coolant ASAP.

Use correct coolant, don't dilute by using plain water to top up.

If your mechanic means that the mounting bracket for the front radar sensor has been displaced or broken in the 'bump' it will require replacement and the radar will almost certainly need to be recalibrated.

Sometimes they are - but not necessarily so.

DTC = Diagnostic Trouble Code. These are accessed by plugging a reader device into the vehicles OBD port - did your dealer do that? If so, did they give you a printed read out of any DTCs recorded? It sounds to me that you need to go to someone competent to get this checked. Has the battery been tested?

... And what were the DTCs found? You haven't said yet what engine you have.

Hello, welcome to the forum. What engine do you have - TSI or TDI? Has the battery been tested? When you get the DTCs scanned - after testing the battery, look for anything relating to intermittent crank or cam position sensor faults.

Definitely would not recommend adding any coolant sealant! - if the loss is only very minor and there are no obvious leaks, I'd suggest topping up with compatible coolant and closely monitoring the level. If only adding a small quantity, safest to top up with concentrate rather than diluted coolant. Do you know if the coolant has ever been replaced? It does have a limited service life for corrosion protection.

Have you had resolution to this yet ? @JackP230725

I would not simply assume this 'losing lock' issue is down to a 'Skoda software' issue if it has developed relatively recently (and not immediately after an update) - the GPS antenna can be subject to failure and I'd strongly suggest at least checking the satellite signals being received. For an Amundsen unit, from the bottom menu bar, select 'View' option - select 'Split-Screen' - select 'Position' option (check box) - Lat/Long, Alt and number of satellite being received will be displayed on split screen. If strong signals from fewer than four satellites are being received, GPS indicated position will be unreliable.

I recall that there is a setting in the GPS menu that allows the number of satellites being tracked to be displayed on the screen - this sub-menu location may vary depending on the system installed, but I will check my Amundsen MIB2 system tomorrow morning. This satellite display would likely give an indication if there is a problem with the antenna.

It should not be beyond a workshops capabilities to test the signal strength from the GPS antenna.

Hello, welcome to the forum. It sounds very like your battery is finished, possibly not even worth having it tested before replacing it. Has that battery lasted 16 years - is there a date stamp on the top of the negative terminal? Does your Mk2 have auto stop/start?

Get the GPS antenna checked.

In the first instance, your radar possibly mistakenly identified the bridge abutments as a bend in the road ahead. In the second, I'd suggest it was operating correctly, as, although only a minor one, there was actually a junction there. Possibly not an issue on motorways due to more open space to either side and no cross-junctions - but maybe your radar is a little oversensitive.

Your charging (engine running) voltage may be a little low and the voltage with the engine off indicates a SOC of around 50% if all control modules were in sleep mode when that reading was taken. With your battery at around 50%, I would expect a charging voltage above 14 volts. This may be part of your problem.

Given the date, time and mileage stamp of the second (B2000 00) fault, I'd just have it cleared and see if it reappears. It may have been due to the battery disconnection. Ditto for the U1123 00 DTC - although this one may indicate an issue with one or more of the ABS wheel sensors if it recurs.
