Bit of an odd one, I was wondering if anyone else had seen this behaviour:

Whenever I go from Park with my DSG transmission straight to Reverse, I get a warning saying that the above two systems are unavailable and they get switched off. I can turn them back on ok and the BSM seems to work ok (don't know how to test RTA).

But if I go from Park to Drive and then to Reverse, it's fine and no warnings or switching off of my driver assistance systems.

Any idea why this might be the case? I mean surely if it was a sensor fault then it would do it every time and BSM wouldn't ever work.

Just an update - ours has been good consistently for about 3 months now. It has long stretches of not behaving followed by long stretches of behaving. I originally thought it might be the weather (cold vs hot) but not so sure now. Will wait until it plays up again and take it in straight away if/when that happens.

Our was fixed with a full radar/camera calibration which also includes 4 wheel alignment. Since they did it we haven't had any issues apart from the odd activation/warning of the front assist system, ironically same corner every time so it must be something to do with the layout of the road.

Whether they do it under warranty as they should is another point, as always it took a bit of open and direct dialogue with the dealer to convince them I hadn't broken it.

A quick update....

Car was in dealers today for them to have a look at the issue. The technician checked the care but couldn't find any fault codes nor anything on the technical bulletins. I'd already showed them the issue so they were able to reproduce it OK but it wasn't generating any fault codes.

So the technician plugged the car into the computer to try and capture the error code when the warning comes up on the dash in case it wasn't being stored but after that the system started behaving, the warning is no longer appearing and the BSD and RTA are staying enabled. So looks like some sort of software bug!

Hopefully, it will now behave itself ;)

Definitely a software bug IMO! The fact that you can turn the systems back on straight away means the sensors are fine. The software engineer in me thinks this is what's known as a "race condition" where the system tries to use an input before waiting for it to settle properly, so sometimes it works and sometimes not.

----

The day I was taking our Kodiaq in for its first service it started playing up again, and I was able to demonstrate it to the service rep. She then tried to video it twice but both times it didn't do it so it's a shy bug lol!

Their suspicion was that the earlier fix done under Campaign 97CN (Traffic Jam Assist not starting) wasn't done quite right by another Skoda service centre and might be playing a part - even though this bug occurred before and after that fix was done. So they redid that and for a week or so it's been ok again.

I'll give it 6 months or until it starts misbehaving (whichever is first) and report back here again.

My blind spot sensors are ticked in the box for being on, but they do not work at all and there is no warning to say they don't work.. I have also had auto break unavailable, and front sensors unavailable this has only happened this week. Skoda are sayings it's because of a tow bar that was fitted. (This was fitted on 31stMay 18 (last year) and only have the problem this week... the car isn't a year old, Skoda have also charged me to look into this.. 😡 when the car went in Skoda found no faults and no faults in the log history. Lucky I have taken photos of the screen. We know it's nit the tow bar but having it isolated Tomorrow just so I can prove it's not that... with the faults I have read in disappointed In Skoda that this seems to be a common fault... anyone got any ideas..

Are you dealing with the dealer only or have you included Skoda UK Exec office?

Exec office is a good call as they seem to be able to conjole the dealerships. The stance would be is that they have found no issues with the tow bar therefore it's not at fault..

My issues with LA and BSD disappeared after they recalibrated the screen.

Sounds like yours is a different issue if they are still ticked but don't work.

So an update...

Firstly, I am more sure than ever now this is a software bug (rather than faulty sensors).

Secondly, I've got a good idea as to what's triggering this bug: towing! Or more specifically, having towed recently - in the week before it starts playing up.

I had noticed that if towing and you put park assist on via the button (not just going into reverse), then RTA/BSM systems also turn off; but didn't consider until now it might be a trigger for the longer-term problem as well. What happens for us is that initially there's no issue, and then suddenly one day the problems start again around a week later and these assist systems turn off every time the car goes into reverse after that.

This has happened twice this year to us already, and now I think about it all the past incidences were probably around the time we borrowed a trailer as well.

Is there anybody else with this issue who might have done some towing just before it started to happen?

My problem with the system had nothing to do with towing as we dont even have a towbar. Probably doesnt help. Sorry.

Same thing happening to me in MY19 Kodiaq L&K (built in Jan 2019). Just read on other forums that this could be related to a brief voltage drop on the battery at the time the Park Pilot is being engaged and might have been fixed by replacing the battery and/or some software update.

Did anyone managed to fix this since Feb and what was the cause?
 
#37 ·
So just had my Kodiaq fixed by the dealer today. They wouldn't tell me more than that a software update was performed.

As I have VCDS, I can notice only following changes and all ECUs have still the same software version as before:

- the 4B Multifunc. Module (J745) - 3Q0-907-338-C - had following adaptation done (I don't think it's related though):
IDE01996-SFT00117-Installation list: specified installations-Telematics Communication Unit,No ,1
to
IDE01996-SFT00117-Installation list: specified installations-Telematics Communication Unit,Yes ,1

- the 69 Trailer (J345) - 5Q0-907-383-N - had following changes in the measuring blocks:
IDE05594-MAS04338,Trailer hitch motor management-Hall sensor,0,
to
IDE05594-MAS04338,Trailer hitch motor management-Hall sensor,7,

MAS04606-IDE03615,Parameter set-Version,Variant F,
to
MAS04606-IDE03615,Parameter set-Version,Version L,

MAS04606-MAS01159,Parameter set-Version number,2,
to
MAS04606-MAS01159,Parameter set-Version number,1,

I can see that they have also coded the 69 Trailer (J345) ecu as the workshop code for the module has changed, but according to VCDS it still seems to have the same SW and coding as before.

Hi Guys,

I have just purchased an 18 Kodiaq Edition, and I have noticed this issue. As soon as I start the engine and put the car into reverse, the blind spot monitor and rear traffic alarm disable with the error message Rear Traffic Alert/ Blind Spot Monitor currently unavail.

What is the warranty period on the car, is this likely to get fixed under warranty?

Regarding the warranty, when to my great surprise I found out some cars would need a cooling upgrade if a towbar was fitted after market, not to mention the problems with the electrics some people then experience I more or less decided that a factory fitted towbar was essential on every car, Skoda and otherwise, and had one factory fitted. To my mind a tow bar is so likely to be required during the lifetime of a car that it should be manditory on all cars to be sure that it is safe, any warranty that is left on a used vehicle is valid, and that people who buy cars used know precisely what they have.

I also think every new car should be supplied with a full size spare road wheel identical to those on the vehicle and an appropriate place to properly store it. Consequently I won't now buy any vehicle without a factory tow bar and what I deem to be a proper spare wheel. You can keep your fancy sensors until the basic car is properly configured in my book.

Currently I have a courtesy car by a different brand and though the start/stop system is vastly better than the Skoda offering it is bristling with sensors all over the place that are constantly going off and it has no spare wheel at all. I loath it and can't wait to get the Kodiaq back when I shall resume turning off the start/stop.

Tow bars to be mandatory?

So likely to be required?

You are on a different planet, last thing most people want on a new car is a tow bar, most people never tow with a car so why should they suffer the costs of having one.

Personally I like all the sensors, they very rarely go off and they are there for our safety. It nice to see you drive around in a different century, bet you have driving gloves too.

I certainly am, we certainly don 't speak to people that way on my planet.

I did not speak of new cars, I referred to the life time of a car. My opinion (apologies for having one) is that cars should be designed anticipating the needs of all the likely owners of a car through to when it is scrapped and not just the lucky minority who buy them new.

I suspect this is the last time I reply to our comments. I'm tired of them.

As regards sensors rarely going off well this morning travelling to work the forward sensors on my courtesy car went off every time someone crossed the road in front of me in city centres. That is pointless, that is what happens in gridlock in city centres. It is not helpful and actually rather maddening to have the car beep 20 times just because 20 people walk in front of the car. The lane warning went off multiple times incorrectly as single carriageways became two and then back again. Pointless, that is the way dual carriage ways are designed. I momentarily and with complete safety ventured over the central line on a lonely gentle bend in the countryside with not an approaching car to be seen in the other direction and again it angrily beeps at me. When I get out the car and close the door the car beeps at me and if I dare to walk away from it to fetch something it beeps again and locks the doors automatically so I find myself having to unlock the damn thing many times and each time it makes a loud beep. Goodness knows what the neighbours think.

Sounds like operator error and not a systems error.

Sorry to offend, just seems like you have a very old attitude to cars and technology, the fact remains is that even you 'bog standard' Kodiaq relies constantly on the sensors you seem to dispise.

One last heave. How can you be sorry and then immediately tell me I have an old attitude? I rather suspect the certificates hanging on my wall from two world famous technology giants thanking me and my colleagues for our contribution to some technology would put an end to this. My particular contribution was, you'll appreciate the irony, sensors. Please stop the lectures, I suspect I should be the one giving them. It is utterly pointless having proximity sensors beeping when the car is stationary. So no more. Stop it. Leave it alone. I have an opinion on sensor technology and perhaps technology in general that is different to yours. No need for insults. Calm debate is perfectly adequate.

I used to have a certificate on my wall, it was for 25m breaststroke, It was my 5th birthday. I never put my 50m breaststroke certificate on the wall as I had grown out of it by the time I was 5 and a bit but I do empathise with you as I do remember the pride of looking back at past success.

Hi Silverbear. Can you enlighten us on what Make/Model of car is annoying you so much? I want to know what to avoid buying as over sensitive sensors would drive me up the wall!

Hi all, Mine developed the same faults. Both reverse park assist & blind spot monitor become unavailable when shifted to reverse gear. Booked in with dealer on next Tuesday. I hope it's just software issue. I don't have a towbar fitted. Any info will be highly appreciated.
