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.

Hello, welcome to the forum. The very first thing you need to do after getting numerous and seemingly random DTCs is test the battery for SOC and health condition.

Suggest addressing the Aux. belt and tensioner issue and see if that could be the cause. Does your automatic stop/start operate correctly? Have you checked the battery voltage?

If your Aux. belt and tensioner are inhibiting correct battery charging - or are allowing battery voltage to drop too low, this could affect the electro-mechanical power steering - but this would also adversely affect starter motor operation, which you do not mention.

Hello, welcome to the forum. That sounds as if you may have a fault with your steering rack or the variable-rate control to it - strongly suggest getting the steering inspected ASAP. The suspected fault will not leave you without any steering at all if the assistance fails completely - but it may well feel like it!

Do you have the headlights actually switched on when you notice this?

Hello, welcome to the forum. I don't drive a mHEV, but I do use auto stop-start all the time in my 2015 Mk3 - EFB battery is more than 9 years old and there are no signs of any issues with the starter motor. The original 2015 AGM battery was replaced, along with the alternator under warranty in 2016 due to manufacturing defects.

Skoda UK cambelt replacement schedule was changed to match other VAG manufacturers recommendations in (I think) 2023.

No stated time interval, 120 or 140k miles I believe.

My post was a reply to a post that appeared to suggest that cambelt replacement interval was still 5 years regardless of other issues with water pump.

Are you aware that the previous 5-year cambelt change interval, mandated by Skoda UK alone, is no longer applicable?

I am aware of the advice to change the water pump on a TDI when the cambelt is being replaced - but is replacement of the belt actually necessary when working on a pump problem only? (I.e. vice-versa)

Good afternoon, welcome to the forum. It may help others if you clarify whether your engine is TDI or TSI? I've assumed from your comments that you have a 2.0 TDI, DSG - is that correct?

Did you have your new battery adapted (coded) into the BMS?

My understanding is that the EFB+ is a fairly recent upgrading of the EFB - I don't think EFB+ batteries were around in 2017, so your old battery was probably not original.

^^^ Agree with this for the DTCs - they aren't in the usual VAG format.

If this is an indication of their 'services' I'd consider someone else for future servicing requirements.

Hello, welcome to the forum. Provided the AC appears to be running efficiently, almost certainly an attempt to upsell an unneeded service.

Check the sealing of the fuel cap - you should be able to hear an intake of air (hiss) when you release the cap immediately after a run.

Suggest getting the battery tested.

If it wasn't like that when you first bought it, something has changed - or possibly you are now driving on roads that are more cambered. Have you checked steering position when the road surface is completely flat?

@jim457 have you got things sorted now?

Check DTCs for any faults recorded, good suggestion for MAF sensor, also check for anything concerning crank/cam position sensors - although reports of these failing often quote reluctant starts.
