This is a widely reported issue across all VAG models using the 1.5TSI! I would have thought a Global company like VAG would value their Brand Reputation more and invest time and effort into a remedy for this issue which seems to affect some but not all users! Cynically for a company that spawned “Dieselgate” should we be surprised! Ford America famously ignored evidence their Pinto car could become a fireball if rear ended as their Accountants argued it would cost less in litigation for dead people than to reengineer the car! Idiots! This “fault” can be a minor irritant when you expect it but heaven forbid a new inexperienced or unwary driver has no power when entering a fast moving stream of traffic! The consequences could be catastrophic and even fatal! This is the sort of thing TV like “Watchdog” used to champion! Are VAG subject to Freedom of Information requests to extract numbers of cases! I expect many more users are suffering in silence realising it’s a waste of time bothering to pester dealer! This is not going away!!

Would you welcome a Co-Star?? 😂

I agree “staling” can be dismissed as a driver instigated error (like we all did as learners!) it’s more the engine petering out itself! This can only be due to lack of spark or petrol vapour mix in the right place at the right time! These are complex engines with sophisticated valve timings and you would expect the manufacturer to know how to properly diagnose! I also take the point that independent experts are often streets ahead in terms of practical experience and knowledge as well as the absolute commitment to actually do something! If everyone who had a problem went en masse to VAG dealer the inconvenience may prompt them ! However in practice more of an inconvenience to users! I’m curious the motoring press and media hasn’t picked this up! It took a TV play to rumble the Post Office who has taken the pxxxx for years!!

That’s interesting? Is the Karoq a 1.5TSI? Manual or DSG? Did it ever exhibit kangarooing pulling away or stalling R Junctions??

What does a dealer use to interface with OBD?? I thought those parameters would need to be changed by a dealer ! Not me as home DIYer????

BP Super Unleaded E5 is 97 ron min, and Shell V-Power 99 ron min. Thanks! That’s very enlightening! I think I was using the fuel quality parameters too loosely and the Skoda blurb in the tank flap just quotes E5 & E10 standards! I have learned now that not all E5 are created equal! And some Supermarkets offer more than the basic fuel! It’s very hard these days to get facts or truths in a world of Advertising, Ai and Internet influencers!! 😩

Forget to say in my ramblings I only used Premium Diesel in the RAV ! Zero problems with DPF/EGR that afflict most modern diesels in short cycle journeys! Similarly the Karoq drinks BP or Shell premium fuel for the reasons you say plus potentially staving off the carbon deposits on the inlet valves which afflicts all direct injection engines! Lastly coming from when “pinking” was prevalent using lower grade fuel I believe the 12.5:1 Compression Ratio warrants it! Somewhere in the Skoda blurb it says 98 is better but not mandatory! I ran my Company Mercs BMW Jags on cheapest fuel and whilst having no problems during lease the oil was blackened after a few days after a fresh service! It may be just a placebo but for the price of weekly coffee it’s my peace of mind!

It’s a shame isn’t it! We swapped this from a RAV4 which was utterly reliable and better built and engineered in every respect but was pushing 15 years old! It was fantastic for our hound as had very low load lip plus unique side hinged tailgate (to avoid trapping tails!) Would unhesitatingly hot a new one but the new one has larger engine normal tailgate and awful CVT gearbox! Don’t worry your choice says e-CVT but it does not have a troublesome rubber or metal drive belt but a proper epicyclic box with few moving parts! A Corolla Sportback was top of shortlist but quite rare and wife prefers SUV driving lookout! Toyota consistently more reliable and with greater longevity than VAG or other makes all day long!!

Add to this I doubt even “factory trained” technicians at the dealership fully understand the intricacies of hardware/software/electronics/petrol combustion etc from first principles! In fact I further believe that the number of boffins back in VAG would be less than a handful and hidden behind Marketing and PR folk whose job it is to preserve Brand reputation! I saw a documentary on Boeing Dreamliner albeit several degrees more complex than a road vehicle but the principles are the same! Boeing outsource the production to many disparate entities who have experts in their respective fields but no central agency to fully understand how they work together or more fundamentally when they don’t! What works fine in. Lab may be very different after 5 years life on the road in the real world!

Brilliant! That is what I would expect a dealer worth his salt to do!

Thanks! I understand that logic but I think it’s happened when I have coasted in neutral! This was a no no when I learnt in the ‘60’s! The mitigation could be so simple as changing the idle speed to say 850rpm! Probably impossible in practice as need to fiddle with ECU and possibly infringe emissions standard! Oh for a knurled screw on the carburettor cable throttle stop!

Thanks Guys! I have a basic OBD! A proper one can cost thousands! I doubt there will be any codes at all! It’s the way they are! I’m going to have a go at changing into first at slow junctions ! Impossibility at larger fast junctions though where you normally cost through if traffic is clear ie roundabouts!

Thanks for the responses! My conclusion is that the 1.5TSI which is fitted across all VAG brands and models is susceptible to stalling in certain situations and you have to learn to live with it! This is endemic to the design and manufacturing tolerances and no amount of software patches will eradicate! The Dealer will charge for diagnostics which won’t replicate the “fault” and elude that you are a “one-off”! (The Post Office & Post Masters defence) in fairness some owners have not experienced this issue! This is a minor irritation not affecting a critical mass of users to trigger a “class action” as is common in USA and Australia (to a degree) We all know about “dieselgate” but VAG have been served with other actions such as water pump (No not Watergate!!) and steering issues! Now in my twilight years I’m not about to go all Ralph Nader and lead the charge! It’s a pity that this niggling “fault” tarnishes what is basically a good and well engineered and built vehicle! Signed Angry of Tunbridge Wells! 😂

Hi Recently acquired a ‘23 model Karoq 1.5TSI Manual! I had read with some alarm that the earliest models could suffer stalling and worse, severe ‘kangarooing’ when taking off! I had presumed that this would have been long ago sorted for mine which is I believe EVO2 model! Pulling away and transitioning from first to second seems a delicate affair to go smoothly! The worst trait however is stalling when slowing or stopping at Junctions! This can range from minor irritation to major alarm depending on the proximity and speed of other traffic! I find myself having to adapt my driving style to compensate for the cars basic shortcomings! I find it astonishing that a Global Brand such as VAG can’t produce a car capable of ticking over in this day and age! Rant over! Has anyone ex of how to mitigate the stalling please??
