The RPM thing or the problem I'm describing with my Octavia??

So it went back to the guys who did the ECU software updates Fri - and rechecked the spark plugs and timing belt (from them being done by the first mechanic). Today's verdict is that the cam shaft has been slightly damaged when doing the belt....the opposite end to where the belt goes ...as it's only slight damage that is why it's running and not showing any major fault codes. And why the tool fits in where it should at the other end. So apparently you can't get just the rod bit for my car and I'd need a full unit at £1500 plus 5 hours labour. Though he was saying when questioned that He also couldn't make any guarantees and if it doesn't fix it I still have to pay. So I'm just gonna drive it and turn the radio up 🤷

Yeah it doesn't. I use it everyday...I do 8 miles each way to work minimum. I know it needs a good run every now and then. I tend to drive lower gear high revs too....

Yes re the rpm. Well maybe that was a separate issue and he fixed that's with the ECU update?

Not sure....I saw the machine he showed me and it said 1000. I'm taking it back in shortly so they can check any misfires on the machine since they reset it on Friday..... My friends dad says he can try squeeze it in to do a compression test but I'll let the original guys I've paid re check it first while they not charging me.....

Thanks for that. Yes I thought after taking it out yesterday that it happened after it got warm on those two occasions, so I think he's made it better but not fully cured it. I'll see what they are suggesting tomorrow about going forward and costings..or I could wait for the tuning guy to be free. My main concern for getting it was checked was to make sure it wasn't the timing. They've stripped it down and said it's perfect so why it started now I have no idea. We just use this car for holidays with it being an estate and I'm anxious about breaking down if it's anything major. I suppose they can recheck the misfiring numbers as he reset them Friday. And I do have breakdown cover. I was seriously thinking about trading it in yesterday but I dont see why I should after 27000 miles! Plus it then becomes someone else's issue. It hasn't shown any fault codes to date .... There were some background menus that they showed me which showed misfiring and moisture on the cat if that's what you mean....I will get them to recheck the misfires this week. Thanks for your advice.....they gonna hate me tomorrow when I reel off all this stuff!

Thanks ....I don't know what they are but I'll tell them next week!

Hello, I have an update on the misfire for the car & wondered if you guys had heard of such a thing. I got back off holiday & the car was getting noisier. I messaged the tuning guy who said he couldn't fit me in for at least 2weeks. As I was getting concerned it was something to do with the timing &possibly causing damage to the car I went back to the previous garage, who hadn't found any issues on the diagnostics machine.They are a large local firm and are dealer level but I don't want to name them on here. they looked at it yesterday & put it back on the diagnostics machine and found the information the tuning guy had pointed out about the moisture in the cat & all three cylinders misfiring, there was a discussion & they suggested it could possibly just be the spark plugs (as they were changed at the same time as the timing belt). After they checked the spark plugs, even though they are not Skoda ones they confirmed that bosch ones have been used & that they were fully compatible& should cause no issues. They then stripped the car down & said that the timing was perfect and that the previous mechanic had done this correctly. They then started investigating other aspects. They phoned me a couple of hours later & told me that they thought they had fixed it & that it was my software that was really out of date in the ECU (this was really out of date because the car is a 2020 model & i have never heard such a thing as updating it) it's been for regular services I've had no information from Skoda that this is anything that I should ever do?? The garage updated all of the software and apparently messed with other certain settings and was happy that the issue was fixed, They took it for a test drive hooked up to the machine and it has stopped misfiring, therefore he is reset all that information. I picked the car up at a cost of £480, purely for five hours labour. Drove it home & tbh all the way home it didn't do the poppin sound at all so I was really confident that they had actually fixed it and it was something as silly as the ecu which was stopping the car from performing correctly (& coincidentally happening at same time as the belt change) however I stopped to pick up my dog from the dog walker & when I got back in the car it did it again. so I've come home & haven't been out in it since. I need to spend some time over the weekend just seeing whether it is fixed or not. My issue is it's not fixed & i a really don't know what to do from here. it had been in for a service it had an MOT & I did the timing belt (with it being five years old) spark plugs were changed. because of the noise starting, the first mechanic decided it could be a coil pack, so did coil pack 2 and another set of plugs. The noise was right from the beginning from getting it back after the MOT etc. second garage who was my friends dad who didn't have the time to carry out any work but he took one look and said it was the timing. The third garage (which was the dealer level garage) put it on the machine and as it gave no fault codes said was nothing wrong. The tuning guy in fairness to him started at the beginning asking me about my fuel I put in the shell v power & the cleaning products but it got nosier.

Thanks.....I think if it doesn't resolve shortly I'll take it back to the engine tuning guy with those suggestions. Thanka again!

Yeah mine says both E5 and E10.....i got the manual out last week and says at least 95 Ron but pref 98.....

Thanks for all that. The belt was changed as I thought it had to be a certain intervals and my last car was 5 years. Anyway another mechanic said it didn't need to be that frequently anymore, but what's done is done...I won't need to do it again as I'm getting a new one in 4 years. I'll carry on with the V power and take it from there!

I know that now ...but first mechanic didn't say anything when I booked it in...I've always had it drummed in to do at 5 year's....infact it used to be 3. But bit late now as it's done, and not sure that is the cause of the current issue.

Thanks so much for your reply. All my friends are adamant it's must be something to do with the timing but the mechanics are saying not and it's more coincidental. It hasn't been stood and unused but admittedly it only does 8 miles each way to work and back. I'm going on holiday tomorrow but when I get back I will do a few junctions up the motorway....and carry on with the V power for a bit before heading back to the tuning guy. It's had a service every year but I don't know what filters they replace. Again, I know the plugs were done with the coil pack but I didn't see what they were. Allegedly he did them at the service at same time as the cam belt etc but then had to do them again with the coil pack. I'll get the tuning guy to check them when and if I take it back. But I appreciate your advice that it will need a few tank fulls, as I suppose that was what I was asking, before deciding to take it back. My sister is going to have use of it while I'm away so it won't be stood

Se drive 115 tsi

It's fine 27000 miles
