A couple of times this week, after coming to a halt in traffic, the engine stops but fails to start again when taking my foot off the brake and a message appears in dot matrix display that says (can't remember exact words), something like Start engine manually. As my car is DSG, this means that I have to move the lever to "P" in order to start again and then move back to "D". This all very off-putting as it is the first time the car done this since I have had the car, purchased in 2013 new, so I have got used to the Start / Stop system being utterly reliable. Any ideas as what is the cause of this?

Sorry not an answer concerning your fault,

but the car with a DSG should start with the shifter in N (not just in P) unless the ambient temperature is @ -8*oC or lower. 

Try that until you get things sorted. New battery or whatever.

Thanks, I'll try that tomorrow if it happens again. It shouldn't be battery issues because it has a brand-new battery on it, installed just 4 months ago and the diagnostic tool shows the battery voltage with engine off as being 12.2V. Tomorrow I will register the battery to the ECU which the diagnostic tool seems to think it has not been done.

I know nothing about the batteries but someone that does will be along.

Did your require coding and was that done?

I did try to do the coding today, but I got a message back saying that my vehicle was accepting the code, so maybe I need to get my local Skoda service approved garage to do it for me? Maybe if the system will accept the coding that my time issue of the solar-powered cooling fan might work again. For those that don't know, an option on my model of Superb was a solar panel built into the sunroof to power the cooling fan when the car is parked in the sun to provide a modicum of cooling inside the car on hot days. It stopped working 3 years ago when the alternator belt shredded itself and the RAC had to give me a loan battery to get home again.

Graham, you realise that you're saying it accepted and saved the coding?

 

If correct, you won't need any Skoda dealer/garage to adapt the battery.

In the nine years I've owned mine, I've had this message numerous times.  Doesn't seem to be related to the status of the battery (otherwise it wouldn't have used Stop/Start to switch engine off in the first place and if system senses battery is starting to deplete when engine is off (headlights on etc) it simply restarts the car without any such message).  What it looks to be related to, in my case at least, is length of time you've been sat with the engine off.  Never had it appear when sat in normal traffic.  Always been when sat parked up waiting to pick up kids or stuck behind motorway closure (both of which happen far too often ;-).  So, it's like there is a timer somewhere in the logic controlling stop/start functionality that says if the engine has been stopped for longer than X, it's now no longer a normal stop/start and essentially the engine is now fully stopped rather than waiting to automatically restart once you release the brake pedal (with a DSG car).  No idea why, there will be a reason why the programmers thought it necessary but not for us mere mortals to know why :-)  So I think it's essentially an undocumented feature of the car and nothing particularly to worry about (other than the inconvenience of having to stick it in N or P to restart and then back to D to drive off).

 

When you say "my vehicle was accepting the code" did you mean wasn't?  Need to make sure you change the current serial number of battery to fool it into knowing for sure it's a new battery.  Doesn't need to be from BEM code on the battery (which generic batteries don't seem to have), just increment the existing serial number by 1.  Some interesting background here if you are using VCDS to code in the battery - https://forums.ross-tech.com/index.php?threads/5037/   I don't have VCDS but that's what I had my friendly local VCDS owing Briskoda member do with the two new batteries I've fitted. 

Any other issues at all? Eg relating to door wiring loom (door locks, windows etc). Obviously stop/start is shutting off your engine ok, so probably battery is ok but if the car senses anything out of the ordinary such as thinking a door/boot has been opened then it will revert to the message to manually restart the engine.

Yes, I did mean to say that it did not accept the code, I will try again tomorrow.

This is the first time I have had this message appear in 9 and a half years of owning the car. Every time it has appeared, I have only just stopped the car and a couple of seconds later the engine cuts out, and then within a few seconds the traffic flows again, and releasing the footbrake, the message appears and I have to start the car manually. When I plugged my Carista OBD2 device in and read all the fault codes, it ran through I think 27 or 28 controllers and found 4 fault codes, all the same and all to do with the TV Tuner (which is actually working). There were no other codes detected, so I did a reset of the 4 codes and have driven the car a few times now and the "start car manually" message has not appeared and the start / stop has worked flawlessly. Checking for error codes again and none found?

I did manage to get the battery coded to the car OK this afternoon, then I did a diagnostic scan of the car, scanning all 27 controllers with no fault codes found.

 

Then I did a detailed report on all the controllers and I get this report:

Any idea what the highlighted fault codes relate to?

 

Since managed to get the battery details entered into my ECU, I have not a repeat of the problem, maybe it's just behaving itself, or maybe it's fixed, time will tell, I'll update this thread if I have any problems.

I spoke too soon, the problem came back again yesterday with the Glow Plug symbol flashing all the time in the instrument cluster. I plugged the OBD3 tool in and scanned the ECU's for codes and got this result.

 

Basic OBD2:

P0121 (Pending) - Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance

CAN network gateway:
00467 - TV-Tuner (R78)

Engine:
05286

ABS:
02214 - Tire Pressure Warning

Navigation:
00467 - TV-Tuner (R78)

Radio:
00467 - TV-Tuner (R78)


Obtained with Carista 7.1 for Android.

 

Today it has performed flawlessly. Any thoughts?

 

I just did a Google search for the P0121 error code and I discovered this video.

 

https://www.youtube.com/watch?v=68pFKbhA47s

Yes with that code a lot of people through a pedal at it 

As above Video clean the throttle body👍

With multiple errors like that at once I feel this could be a low voltage issue. I suspect all is still not happy re battery and/or charging.

 

The flashing glow plug light indicates an engine management issue -which could also be voltage related.

The errors for TV tuner can be left alone

i have still never solved the exact problems

Greetings and apologies to Graham Butcher for tacking my (related) query onto his post,

 

I have a 2014 Superb Combi SE 140 diesel manual gearbox and I think the winter has finally taken it's toll on my battery; mind you it is the original battery (I've had the car since it was 9 months old - aah). The car still starts but the stop/start doesn't stop/start(?) any more even after an hour's motorway journey.

 

I'm confused about the replacement side of things. I've read this post and the query about coding. I've read various articles about stop/start batteries needing encoding to the vehicle. Halfords (hmm) say the new battery has to be encoded.

 

That's all fine BUT my vehicle manual states:

"We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations". (Page 192 REPLACE)

 

Now the question: Is the manual's statement a disguised way of saying that it does need coding when it states "installed properly" or does the battery not require coding?

ps I was going to check whether the existing battery is an AGM or EFB, apparently this is important, but it is persistantly precipitating it down outside so I haven't yet.

@Charade Have a read here on the top of adapting battery

 

@varooom Thanks for that. Not haviNg a VCDS gizmo, if I understand the opening of your article correctly, as long as I replace the battery like for like then after a short drive and a bit of a twiddle all should be well?

Brilliant. Thanks again.

Yes that's the theory of the matter, if you eventually get chance to view what is installed, then me or others can give you a recommended drop in.

It would be ideal if you did the swap, then went on a nice long ride to give it a nice healthy top up.  Then just drive as normal, if the Ah rating is say only +/-2 difference, really you should be ok.

 

If you get chance, you can always find a local VCDS user or equivalent tool that you can adapt in the battery to speed up the learning and be 100% it's happy as can be.

@varooom

I think I'll go for the same as what's in already - see pic attached.

 

I know it's not rocket science. In my "youth" I've changed big ends on my Trumph Herald, for some reason flashed my Triumph Spitfire from positive earth to negative earth (I still can't remember why), modified the valves and head on my mk2 Cortina GT and put a recon engine in our VW caravanette (1971) but now, just starting my seventh decade, when I look under the bonnet of my Superb I wilt.

 

I think (hope) I can manage a battery change though 🤗.

 

AndyW

Edited 2 March, 20233 yr by Charade

Looks like a Varta E39 will do you proud (same as what I replaced just a few months back)

That'll be the one that goes in then. I  hope it is just the battery causing the stop/start not to stop or start.

Still, let's think positive. After 8+ years it's got to be a factor.

Thanks for your help.
