Yesterday evening, I put the car on charge and immediately I heard a very loud noise, like cooling fans running at high speed. I turned off the charger, then on again and the same happened. so I left it off-charge for the night. This  morning it charged as normal, but when I went out later, the clock was wrong and had changed to manual. When I set it to internet time, it immedieately showed the correct time. Is this just another glitch or something more serious?

I contacted the service manager at our dealers asking whether this was a known issue, but was asked to take the car in for a check-up. As it's running well, I cannot be bothered going on a 60 mile return journey!

I notice the same noise when I charge mine, although I wouldn't say it is loud. I just assumed it is cooling the orange bits whilst charging, so I walk away and let it get on with it.

 

As to your Dealer response, it seems fairly typical. They don't seem to know very much and expect us to take the car in each time. I am considering buying a battery charger/conditioner and would like to know what type of 12v battery is fitted. So I called this morning. Dealer rep No.1 - "No idea". Dealer rep No.2 - "The cost of a new battery is £185, so it has to be gel". 🙄

Thanks Sir Ron. I only heard the reported noise once and it sounded very loud. The handbook shows how to charge the 12 volt battery with an external charger, but my battery charges either when the 400 volt battery is on charge, or (so I was informed in another thread) when the car is being driven in hybrid mode. I check the resting voltage regularly using a voltmeter plugged in the boot socket and it's always between 12.1 and 12.3 volts, rising to 12.5 volts when the main charger is on.  As for dealers, I think they are good at selling cars and at routine servicing but anything else they are less useful. This is why I didn't take the car in - it's running well and I'm certain that the diagnostics would not show anything and even if it did, what could they do? I would not dare keep the iV beyond three years owing to its complexity, so after 18 years with Skoda (or 21 when a change is due) I'm likely to go for one of the Korean hybrids with a long warranty.

Jim, Like you I have been with Skoda a long time - since 2002 - but this one may be my last, unless there are big improvements to updates and reliability in the next two years. BUT it seems all cars are over-engineered these days. I've looked at the forums of Mercedes, Ford and Nissan recently - all with similar problems. And get this from the Hyundai forum - " I looked out of my window to find my boot/ tailgate wide open of my 2021 Tucson! The alarm was never triggered! Both keys were stored away from my persons and when I went outside, all doors were locked and windows wound up! I also checked the hyundai blue link for any alerts but nothing, the status of the car was showing that tailgate and doors were closed! No alert of car alarm triggered 'check vehicle'.

This is not the first time I've had electrical faults with this car even though its brand new! The sound system went, I couldn't open the rear doors from the inside or outside to get my children out during the second week of having the car and the car lock was disengaged! I also could not access the boot space as the tailgate refused to open and I had just done a huge grocery shop. I have taken the car back to hyundsi in Chingford and received an update via USB but since then problems keeps occurring of the same/similar nature...and now the tailgate spontaneously opening.

I am so done with this car and I look forward to the day I get a TOTALLY new different vehicle!!!!!!"

 

Sounds familiar, no?

 

I suppose most of the latest hybrids will display quirky faults. Perhaps I ought to get a restored Morris Minor 'woody' from the Morris Minor Centre in Bath! A screwdriver and a set of spanners would be all I needed for any mechanical work.

I think this might be the answer. 1964 model on sale in Bristol for £19,750.

Did you ever get a resolution to this problem OP? Our Octavia has just started doing exactly the same thing.

Hi,

 

I have a similar problem, recently the engine cooling fan has been running really fast when charging, but only after it has been used, it happens even when moving the vehicle just a few meters. I leave it to rest a for a while and seems to charge normally. I also noted that the engine cooling fan is running excessively when out on trips, doesn’t matter whether it was long or short, petrol or battery. Went to the local Skoda garage yesterday and they have identified a engine temp sensor fault. Hopefully this will be repaired today and resolve the issue.

Mine did this today, really loud fan as soon as I plugged it in and was still doing it twenty mins later. 
 

decided something wasn’t right so unplugged it and sat in the car to cycle the ignition, got loads of errors, engine error, don’t go above 4000rpm error, visit workshop, bongs and bings everywhere, fan still blowing. 
 

got out, locked, unlocked, back in, started it. Then……. Nothing, like it never happened. 

I thought I’d been luckier than most with this one, but maybe the errors are starting to creep in!

Engine temperature sensor fault, resolved all fan issues once replaced.

I’d love to know how they can diagnose a problem on a very complex bit of machinery without ever seeing it. 🤔
