This is my second Octavia with the 7 speed dq200 box (now covered 70k), I've had no issues with either, both always been silky smooth. Personally I just use in in normal driving mode, tried eco, don't like it, neither did I save fuel. As the above poster has mentioned, I always place mine into neutral, too, if my start & stop is off & I've stopped at a lights. I always have whether I've owned an auto or a manual transmission. The dsg is the smoothest duel clutch transmission I've used, worst the infamous Ford power shift slush box. I've also previously owned a few torque convertors, too.

This engine seems to eat plugs, I had two sets fitted on my previous 68 plate 1.5tsi act engine. First set started to fail under 10k, codes were random misfires and single cylinder misfires. My engine started to randomly run rough on tickover and then gradually became worse from a cold start over time, until eventually the engine ran on 3 cylinders from a cold start. Once the plugs were changed again the engine was back to A1 again. My current 19 plate 1.5tsi (different car now), had its plugs changed 10 months ago, up to now I've experienced no engine issues whist running or during tick over, its now covered 70k. Always ran smoothly within any conditions.

From what I've read it's for cars aged 3 to 6, up to 100k on the clock. One minor & one major service inc plugs if you have a petrol car.

Yes I'd pay monthly, too, interest free. I was just pointing it out that it was £200 cheaper at the moment. I'll probably take up their offer. As my years Skoda extended warranty runs out in Jan, my car is 6 next year. I took this out on my previous Octavia, cancelled it half way through to buy my current estate. I wasn't charged an excessive amount either for breaking my contract, just paid for what I'd already used.

Just for info, the "all in", warranty & servicing package is now available until the 02/12/24 with £200 off. So it's now at £695 for two years.

As previously stated, take your battery for a free load test at a trusted garage. I personally have never owned a car yet (owned many), that the s/s system has worked 100% of the time. This is my second Octavia with the same engine as yours, mine doesn't work 100% of the time either, when it does it's not always 100% reliable either, I'm certainly not concerned about it though, my battery is good. My car always idles consistently, slighter higher for a few seconds after a cold start then drops back to normal. No increases at junctions or lights when stopped. This engine can be marginally jerky to use when very cold, although within the bounds of acceptability within my experience. If you are not sure about it's previous service history, I'd also be tempted to change the spark plugs. As mine started breaking down x3 of the 4 within two years after being changed within my last octavia, my current one had them changed a year ago.

Doesn't sound right to me, I have the dq200 7 speed dsg box, second Octavia I've owned with this transmission, always had 100% smooth gear changes in all gears, no matter what speed I'm at. If you are wanting to keep it, may be best to have an independent gearbox specialist for them to take a look & give you their opinion.

I've had plenty of issues with my last 2018 and current 2019 1.5tsi act Octavia dsg. I think I jumped ship a bit late on the vag reliability front. None of them have been major issues, just software/hardware glitches, false alarm activations, rear hatch lock failure, rear wiper motor failure, spark plug failures under 2 years old, ongoing rear hatch water ingress issue with my previous octavia hatch. I've only owned Skodas for 2.5 years so far, so within my opinion very average on the reliability front. My current Octavia has 68k on the clock, fsh. Previous under 50k when I'd sold it, again fsh. They''re great for space, both dsg dq200 transmissions have been excellent, zero issues, 1.5tsi act engines also very economical with enough power for me. I'd expect some issues with a car 10 years plus old though with nearly 100k on the clock, Although I've previously owned low mileage cars (none vag), had issues with them, too.

Fantastic news. always best to have it load tested, even if you'd previously tested it with a multi meter.

Possibly the plugs, was with mine, but without an in-depth diagnostics, hard to tell. Last place I'd ever want to take my car out of warranty would be a skoda dealer. Just out of interest, does yours use any oil? Mine is on 68k now, useless around 1/4 of a litre of oil every 3 months or 2k covered. My last one didn't use, any.

When I had the EFB battery replaced my previous Octavia, the garage coded it in with cloned software, think I paid £150 all in with a 2 year guarantee. I've not as yet coded a Skoda battery in myself, so can't advise you on then, as I'm fairly new to vag. Hopefully the new battery may sort out your running issues, once you've coded it in.

With gdi engines the inlet valves are not washed with petrol, prior to combustion, hence carbon build up. Some gdi engines engines seem more susceptible to this than others. I know with the older mini, pug, bmw gdi engines those inlet valves were cleaned with a walnut shell blasting machine. I'd have thought if they were heavily carboned up it may of effected the performance of the engine, too. Although I'm no expert. Those 1.5tsi engines do seem to eat plugs, though. My last 1.5tsi ACT had two sets within two years. Stating the obvious have you had your battery load tested?

I had a similar issue with my previous Octavia 1.5tsi, initially it was mainly at start up, gradually became worse over time, the AA did a code reader on it when it threw up an ecu light (the engine then sounded like a bag of hammers), random cylinder misfires. I had an extended warranty at the time with Skoda, so I then took it in for a diagnostic, they confirmed 3 of the 4 plugs were breaking down, even though they'd supposedly changed them less than two years ago, they replaced 3 under warranty & I paid for the fourth myself, as they were to tight to replace it under warranty. Anyway it solved the issue. Once the engine had warmed up & the AA breakdown fella had arrived the engine was running sweet again, but fortunately there was some historic codes stored.

Or no not another turn off during every ignition cycle job, even worse if you have to turn it off through the screen, at least with the s/s, there's a button. I didn't actually consider that, I'll check mine tomorrow. At least I haven't got lane assist to contend with.

I'm fairly new to Vag/Skoda, only owned 2, 1.5tsi's & the 1.0tsi in the scala. The 1.5tsi doesn't seem a bad engine within my experience, very economical as it shuts off 2 cylinders around 30% of the time. I've noticed no increased economy between e5 or e10 or any performance difference. Not that I bought my Octavia estate for performance. I've mainly owned vauxhalls from the the 80's onwards, but they've took a nose dive of recent, especially since Stellantis has took them over. I've avoided any wet belt engines up to now.

Have you tried un-ticking the interior monitoring function off within your settings menu? Seemed to work for when a had a couple of random alarm activations for no apparent reason. Mine hasn't gone off again since I did this.

I mainly use E10, I have noticed no difference with e5 on performance or economy, only the fact e5 costs more at the pump. Although I'm not a sporty orientated driver, either. I always drive within "normal", driving mode, too, not eco. S/S usually turned off, I have around 32psi within all 4 tyres, too (205 55 16's). looking back, I don't think the slow breakdown of my plugs had initially effected my mpg too badly, but once they'd thrown an ECU light my car was running like a bag of hammers. I'm also running with 0w 20 oil, as recommended by VW/Skoda for my engine. Earlier on within it's life Skoda had used their 5w 30 oil within it, may make a marginal difference on fuel economy. Thinner oil, marginally less friction.

I've owned a couple of these engines now with dsg transmissions, my current Octavia has covered 68k on a 19 plate (1.5tsi act). It's smooth generally at all speeds or when hot or cold. It makes no difference whether I used e5 or e10 fuel. I had a similar issue to you with my last 1.5tsi, started at around 24k, no ecu light initially, the symptoms gradually became worse, when the ecu light did appear, I had a diagnostic done at Skoda, they diagnosed failing plugs, even though they'd changed them less than two years ago. So I had them replaced under their extended warranty again, although they'd only cover the cost of 3, I paid for the fourth plug to be replaced, as Skoda were too tight to replace the full set, as only 3 had failed. After that the car was A1. Coil pack could also cause similar issues, too. Although I'd say there can be a very slight jerkiness to this engine at times, only minor though. Within tolerances I'd say though, mine would occur say when taking my foot off the accelerator whilst slowing down when turning right on a round about, but I have to feel for it. Nothing compared to when my car was really kangerooing. I've averaged 48mpg long term from my current Octavia, that's a mix of b roads, town and A road use. Even around town I'm getting high 30's, without hitting very heavy traffic. I've never owned a car yet with s/s that's worked 100% of the time with any manufacturer. I generally turn mine off, anyway. I'm presuming you have a Skoda extended warranty like myself, if so you could book it in for a diagnostic, but as you have no ecu light, they may not find anything & may possibly charge you £135 for the pleasure or whatever Skoda charge these days. I just couldn't believe they wouldn't change 4 of my plugs for what the extra plug would have cost them. At least they covered my diagnostic cost.

Yes this was my previous Octavia, resolved eventually by a new set of plugs. By the time a code was thrown up via an diagnostic, it was running very rough.

I'd probably go for anything mid range, summer tyres, unless you live far up north. I've found kumhos to be very decent for the money & longevity, as like myself you seem not to be a sportier driver these days😅I'd stick with the load rating from factory on all 4 tyres, if you are fitting 4, avoid fitting XL tyres if not required. I try to fit 4 at a time, if possible or at least 2 across the same axle.

I also suffered from this exact noise with my previous mk3 Octavia 1.5t ACT DSG, at 1800rpm, only. Put up with it for 18 months until I sold my car to buy my current 1.5tsi estate without this annoying noise. I couldn't find where it was coming from, sounded like it was coming from behind the dash area. I tested the fuel pipes, moving them whilst someone revved my car, made no difference.

Good point about an earthing possible fault. I bought my car from a skoda dealer 6 months ago, at that point software updates were up to date. The battery seems to be charging and holding its charge OK. Hopefully some codes would have been logged due to the intermittent alarm activations, also possible that the head unit screen was a separate issue. I had no issues with the alarm, locks or screen until around a month ago. It's also very intermittent. Screen has been OK now for over 2 weeks. I'll live with it until it annoys me enough to book it in for an diagnostic. Thanks for the info.

Thanks for the info. I've just had my battery load tested and it's good. I also have the skoda extended warranty, software updates are not covered, probably amongst other stuff. At the moment it seems as though the car is suffering from random tech glitches or has done so for around the last month. I'll see how it goes, if I keep having issues with it I might take it into skoda or else where for a diagnostic, as I'd have thought there would be some fault codes stored with the the alarm randomly sounding or possibly a good auto electrician. The head unit has been A1 over the last two weeks, prior to that I had around two weeks of it randomly turinging off and then back on whilst I was driving without me touching it. This is my second mk3 Octavia, both have gave me reliability issues during the short time I've owned them. I wont be buying a mk4 for certain, especially with their well known info screen software glitches. My Octavia estate is a very practical car, but plagued with electrical gremlins. If I ever find out what has caused the glitches ill post why.

I've had a few random alarm activations with my 19 plate Octavia over the last couple of weeks. The first time it went off, I walked away from my car, locked it, as you do, 2 mins later I unlocked it then sat in the drivers seat, closed my door, sat for around 1 mins, then put my key into the ignition barrel, whilst I turned it, the alarm went off for a couple of seconds along with the hazard lights, then then car started & all OK again. A week later, I parked my car up with the two front windows open. Got out of my car with my ignition key, walked around my car, got back in it again, shut my door, alarm went off again, used my fob to press the unlock button, alarm still was going off. I then put my keys within the ignition & turned it & the alarm then went off. So I decided to play around a bit more with my alarm. After turning my ignition off, I opened the drivers side door & shut it again whilst sat in the car. 10 seconds later the car locked it's self without me touching the key fob. This is a few weeks after my head unit was randomly turning it's self off & on, so no idea if it's just coincidence or not. I then decided to check my car battery prior to starting my car, just in case my battery was low, it read 12.49v, after being stood overnight, so that looked OK. Although I've not had it load tested as yet.

There's a place in Norton I've used before, you'd have to ring them first (The Cobblers of Norton).
