Does anyone know why my car did this?

Prior to this happening I was in second gear and everything was normal.

This happened twice in a 8 month period.

Each time i turned off the car and turned it back on and everything goes back to normal.

Car details

Skoda Karoq

1.5 TSI

2018

Best get it plugged in and read to see if any fault codes logged. Misfired maybe. EPC light on. Have the spark plugs been replaced yet?

That reads like it's going into limp mode. Get the fault codes read.

I got it plugged into a reader and it isn't showing anything wrong.

Spark plugs are 4 years old and am going to get them changed in a few months time when it goes for it's next service.

That would suggest that the reader you are using is not completely compatible with your vehicle.

The EPC light is on and something is apparently triggering the engine into limp mode, there will definitely be a DTC logged on the ECU.

+1 for this.

If you're in limp mode, or have been, there will definitely be at least one DTC logged. Some codes go away by themselves (e.g. alarm activation stage 1), but codes logged into the ECU shouldn't, until cleared. I read misfire codes on my previous car from six years before I bought it.

BTW, if you clear a DTC without rectifying a fault, this can sometimes cause a problem to 'go away'. The car will see the problem reading as the new baseline, meaning everything is fine in its world. Unlikely in this case, but just be careful clearing things if your reader doesn't have a history feature (like OBD11, etc).

EPC light can come on with misfires and it is not unknown not enough in a cycle to log a fault code. At the very least get out the plugs and inspect. If out as well to replace.

Surely though, if the misfire was mild enough to not log a fault code, it would be just the EPC light and not limp mode? EPC doesn't always equal limp home (although it does most of the time).

Surely / Shirley it should. But surely what has gone before may have happened. Or I would not have mentioned it. If only everything in life was as reliable as a Golf. They could go into limp mode , misfire with a sooted plug and no fault code logged. PS. Most of the time or all the time? Tell that to thief that had 1.4 TSI Twinchargers. They liked Cylinder Deactivation even before VW introduced the concept..

If only everything in life was as reliable as a Volkswagen! At least, that’s the one where she doesn’t drop the keys down the drain

@Ootohere ah, but when they went into ACT mode, the twincharged engines made sure to log plenty of codes! Although that said, if it was a pre-2012 then you didn't necessarily need to read the codes - the pistons falling to pieces usually gave an audible notification - and it wasn't just Revo that noticed 😂

I have had 6 of them, bought as rejected cars returned to Skoda or accident damaged. Repaired and sold. I ran one on the road and had one for the 1/4 mile sprints and hill climbs. I still have a rolling shell but sold the tuned engine and DSG. Car will be rebuilt to be a sleeper sometime. PS. Remaps were fine. Not the REVO map though. I ran stage 2 and 230 bhp. Blueprinted. Built by a great engine builder in Dundee that was a Hillman Imp race driver. He knew how to do potential crap engines to not eat them selves. Hiperflo 250 102 Ron petrol. Road car standard engine, stage 1 and running on Tesco momentum. DSG with clutches from Australia and software. Denso plugs. Put the original engine in it to sell. It was 1 of the first 50 into UK 2010. Still on the road someplace. A few of the early demonstrators were owned by members here. They were not allowed sh!,te.

From what I understand, tuning the engines wasn't the issue - it just put more strain on sometimes flawed components that were already weak.

HIPERFLO is some serious stuff, proper race juice.

Inlet manifold, one fouling / oiling plug and carbon build up and the tip burning off, crap mapping from VW, rubbish OEM plug choice which they changed, to still crap. dodgy components with the CAVE, not that better with the CTHE. OIl Spray Jets / Squirters, there were 2 breather pipe mods tried.

Then Long life oil and only 3.6 liters when 3.9 was really the minimum needed, and 5w 40 FS not 5w 30 FS III.

Bore wash. Enough detergent in the oil and then in the Super Unleaded, and they really needed and still do 97 or better 99 ron minimum. And engine to temp and booted and no gumming up rings.

VOLVO sorted out Twin Chargers. But then Stefan Jacoby. The CEO of VW USA who was a VW Family insider that huffed off to Volvo / Geeely when he was not made the boss knew where the faults were.

After all he introduced the Green TDI,s to the US and must of known about the defeat devices IF it was him that was the whistle blower. Brought VW from 1st place to 2nd behind Toyota.

Then he left Volvo (sicj leave...) for GM Global. All that time and even when he was with Mitsubishi he was a VW Man born and breed. Cuckoo in the nest.

Independent now. Selectively deaf dumb and blind. Knows nothing and everything.
