Hi, yesterday morning I drove up to Stafford from Exmoor no issues whatsoever, however this morning driving back with my elderly mum on board we broke down at Bridgwater, as I was driving up the off slip the engine appeared to flutter slightly for a couple of seconds then all seemed fine, I assumed it was possibly the road surface, however got about 1 mile off the motorway and the EPC light came on and also the engine light and it was popping and spluttering so I rolled off the road and switched off, I thought it felt like the coil packs had failed, the roadside assistance arrived quickly ( green flag ) plugged in the car and he said it looks to be that 2 coil packs have failed, he unplugged the middle and right one as you stand in front of the car looking under the bonnet and it made no difference with the engine running but shaking badly but when he removed the 3rd one the engine stopped, I’ve got 3 brand new coil packs at home so he brought us home and I replaced all 3 but it’s made no difference whatsoever, I’m going to get 3 new plugs tomorrow, does anyone have any other ideas as to what could be the issue please, the car is a 2022 ( sept 1st ) 1.0tsi 95hp with 29000 miles on the clock and a full Skoda service history that we’ve owned since new. Cheers Paul

By 'the 3rd one' (when removing the suspect coil packs) do you mean cylinder 1? I.e. the cylinder at the timing belt end of the engine.

What were the DTCs recorded that the breakdown tech found?

Very possibly failed spark plug/s.

Hopefully replacing the plugs will fix it - check very carefully that none of the tips of the old plugs have detached and fallen inside the cylinder.

Hi Warrior193, apologies yes cylinder 1, the plugs all look intact, the plugs in cylinder 2 and 3 were wet, my neighbour is a mobile mechanic he is ordering the plugs first thing in the morning and he said he’ll plug it in when we get back from a family members funeral tomorrow afternoon, we’ve hired a car for the day tomorrow 🙄 cheers Paul

The recovery guy didn’t give me the DTC’s but he said there were a lot of things flagging up, just to say we have never had any engine issues whatsoever before, only the heater fan issue that I resolved earlier in the year cheers Paul

Maybe failing crank sensor. Seems odd that two/three plugs or coil packs have failed at same time although I have read that failing plugs can take out coil packs . If the gap is to large then the coil packs have to work harder and can burn out. Hopefully new plugs will cure it and once its plugged into diagnostic maybe clear any historical fault codes and then run engine and scan again.

Ok, so plugs and coil packs replaced and unfortunately no different, it’s running rough although not shaking now and smoking out of the exhaust and it cuts out after 10 seconds, I’ve done a short video but unfortunately I can’t upload it due to the size, my neighbour is going to plug it in to his snap on ipad and hopefully get to the bottom of it, in the meantime any other ideas would be gratefully received please. Cheers Paul

It could be a MAF,02 sensor or crank sensor or perhaps high pressure fuel pump etc. No real way of telling until it gets scanned for codes. Hope its a simple fix. What colour is the smoke from exhaust.

Ok so he’s plugged it in and it’s saying misfire on cylinder 2 & cylinder 3 also secondary battery is very low? I was unaware the car had 2 batteries or am I misreading that fault, also the fuel cut off has activated ?

I’ve also just remembered when the car stopped it did come up with something about stop start on the dash but because I was concentrating on getting off of the dual carriageway I’m unsure exactly what it said, I’m just wondering if there is a way to reset the fuel shut off valve? Maybe disconnect the battery ? any thoughts would be appreciated. Cheers Paul

Get the starter battery load tested - at simplest, measure the battery voltage at the terminals with a meter while engine is being cranked-over on the starter.

Did the vehicle suffer an impact around the time of the breakdown?

Could the SS message you saw have been something like SS not available?

Hi Warrior193, absolutely no impact, just rolled to a stop, yes I believe that’s what it said SS not available, I’ll get the battery tested when my neighbour comes around this afternoon, Thank you for your suggestions 👍, cheers Paul

This earlier forum discussion may relate...

Hi, I’ve got an update, I asked if he could do a compression test as I was panicking a bit, it’s been checked and all good, he’s also checked all of the fuses, 3 fault codes came up as shown below, he’s going to do some research tonight, however I did tell him I’m a member on here and said I would ask if anyone had any thoughts please, many thanks Paul
