If you read this thread carefully you will note the issue reported is with the EVO2 engine in manual, it is an issue across the VW range. Neither of the cars you have had had a manual EVO2 engine. You don’t have a clue what you are talking about.

Issue with the EVO2 engine and the manual gearbox, easy way to tell it comes without an engine cover. Introduced maybe late 2022, also reports on other VAG car forums, ie T Roc etc with same EVO2 engine in manual.

Understood, I’ve been doing similar. Mainly popping it into neutral before the revs drop too low in a higher gear on the approach to a junction or roundabout and then select the gear I need from neutral, shouldn’t need to be driving like this though! If you find yourself on an empty piece of road, iI’d be interested to know the outcome if you slow down in higher gear and shift down to 1st or 2nd, ie if it still stalls when the revs drop as you press the clutch to shift down.

Well done if you have cracked it, I assume you have tried slowing down as if approaching a junction or roundabout in 3rd or 4th gear, dipped the clutch to change down with no engine cutting out.

interesting! I’m assuming you have or are going to try to replicate the behaviour that would have caused the car to cut out previously, would be great if it cures it. I’ll wait for the full results of your testing before I get too excited though, fingers crossed though!

Straight kick in under the centre of the rear bumper then step backwards away from the car. You need to step backwards otherwise it doesn’t function, presumably for safety reasons.

Almost all of us reporting this problem seem to have a mid to late 2023 or 2024 1.5TSI manual Karoq, so this will be the evo2 engine, ie new version without the engine cover. So I think Bigjohn may be on to something linking the issue to the evo2 engine.

yep, I think you are spot on. A bit like Ken2 I have tried to adjust my driving to move down through the gears anf keep the revs up. But slipped a couple of times today, slowing down in 4th I think at a roundabout, dipped the clutch to change to 2nd, cut out and had to pop into neutral and press button to restart. I don’t think so much it is the slowing down in a high gear that causes it to cut out, but when you dip the clutch to change gear in those circumstances. If you have a look at the rev counter when you dip the clutch it drops significantly. Ie. Slowing down in 4th, revs down below 1000RPM, dip the clutch to change into 1st or 2nd, revs drop below 800 and it cuts out. In terms of demonstrating the issue to the dealers though it is just a shame it only does this intermittently. Ie today after it cut out I tried to replicate the same manoeuvre and gearing but didn’t get the same outcome (didn’t cut out).

https://www.trocforums.co.uk/threads/engine-cutting-out-at-junctions.3524/ interesting reading, and also the thread I posted on P1

I am sorry to say but unless I can replicate the issue then I think my chances of success at the dealers are very low. If I have some time on my hands I might spend some time experimenting like the person did on the TROC forum I quoted on the first page. For now I have been making a conscious effort to change my driving and keep the revs up by changing down on the approach to hazards. Interested to hear how you get on later this month, I hope I am wrong and they take it seriously. I suspect it must be a software issue, ideally you want to be able to take a member of staff from the garage out with you, and be able to replicate the issue to them. Ie, certain gear, slow down on approach to hazard and get it to cut out on demand whilst the car is slowing but still moving. If I could do that I would be booking it in like a flash!

Likewise, Jan 24 delivered new from factory

sounds like a good outcome, hopefully they gave you a good price for yours and a decent discount on the new DSG one so you are not too much out of pocket, regardless, as you say though safety comes first!

Being in too high a gear on the approach to a hazard, be it a junction or roundabout is actually the opposite of engine braking, slowing down by using the gears would be engine braking. That said rather like Ken2 I am going to make a conscious effort to keep the revs higher and will report back in due course.

I am fairly certain it is related to this, issue occurs for me when slowing down to a near stop from a relatively high gear, ie in 4th or 5th and slowing down for a roundabout or lights. Revs are obviously low in 4th or 5th when slowing down to 10mph, when I dip the clutch to select 1st or 2nd revs drop below 800 and engine cuts out. Annoying thing is it doesn’t happen every time and is hard to replicate.

I wouldn’t worry too much about those three things myself, however, alloy wheel locking nut- make sure that is there and for peace of mind I’d check it’s the right one.
