Okey, I have maybe been able to get to actually a thing that could make sense; where the error might point to. I got this on channel 13 (and some others, for rear right, front left, front right). If I google for 65535 error, I come to things like this: http://wiki.ross-tech.com/wiki/index.php/65535. Now, i'm not sure if that actually is correct or that it says something completely different. Would this make any sense, and if so, how to resolve it?

Can try to do that this. Ive already got the sensor changed recently (and master & slave cylinder), but will do the test tomorrow! Any other sensors to monitor that we can think of?

oh its a modern one with TPS! Found out the hard way not so long ago :), great usefull system, that u dont know you need until u need it 😂. So yes, it has the tire pressure monitoring. I went to drive with OBD11 plugged in, live data on the weel sensors (in straight line, safe etc etc). They all give the same speed reading, no irregularities there. Definitely was a good idea tho - as it somewhat makes sense. Especially with 5ath and 6th gear not being so super different (I almost dont get that there is a 5th). in the 5th it sometimes flickers between thinking its in 5th or 6th untill it goes doesnt show any. Maybe it might be with engine speed sensor, similar idea that higher speed, the margins are smaller?

I think that was still me haha :), just didn't get it resolved yet sadly. I think as well that the cruise control is just a 'symptom' of a different system not working / communicating correctly. What is even more weird is that that its mainly in 5th and 6th gear only. If it's somewhere with pedals, I would assume it happens with all gears. A transmission speed or vehicle speed -maybe. But I've tried to put the car on the same speed in 4th gear (instead of 5th), and all works fine. So I'm guessing wheel sensors are fine then. I've had it checked by Skoda, independent shops, but none really could figure it out (and gave up pretty quick as well). No error codes or none. A sensor or loose wire still makes sense, if it's related to 5th / 6th gear. Or a loose'ish bracket or something that makes it thinks it goes into the neutral sensor? Diagnosing hasn't given any other solutions. Is there a way to approach it to find the solution? Do like a full electrical test or whatever?

Hmm but with vehicle speed sensor it doesnt make sense its only 5th and 6th gear. In 4th and lower it all recognizes it correct.

Hmm got master cylinder & clutch sensors replaced. It also only occurs in 5th and 6th gear. Is there a sensor only for 5th and 6th gear?

I've identified something new with it; related to not recognizing the 5th/6th gear properly. Which is the following: -> When the car recognizes gear, and I release the throttle (gas pedal), the car smoothly reduces speed/gas -> When the car doesnt recognize the gear, it bonks /shakes a bit when I release the throttle. This happens simultaniously when the car doesn't recognize the gear; for example, in 6th, same speed; and I release throttle while the car recognizes the gear, it goes smooth. When it doesn't, it bonks/jerks a bit when I release the gas. This makes me think it might be something in the gearbox; like the synchronizers or linkage. What do you guys think? Any idea on what that can be? Or is it just the computer responding 'weird' as it doesn't know which gear it is in. Thanks,

Guess what, i'm still here! Got the master and slave clutch cylinders and the sensors all replaced. Didn't solve it sadly. So still the same issue exist, and I have no clue how to go further with it now. My shop also has no clue, as there are no error codes or nothing in the logs indicating that anything is failing. Any suggestions on parts that I can change next to see if it works? Or how to problem solve it?

Thanks J.R., I'll be going back with the garage with this info :). For reference I think this is the topic you were talking about:

Okey I'm back again! I've gotten the sensors replaced (clutch & brake sensor). Sadly - that doesn't appear to be the solution. So back to the thinking board. The symptons: - 6th gear, constant speed, after 1-2 minutes, the gear indicator stops 'working' (doesn't indicate a gear anymore) - 5th gear, doesn't recognize it's in 5th gear properly, stops showing any indication of which gear it's in - 4th gear, it works pretty long, but after some time, it sometimes drops the inidication as well. The moment the gear indicator drops, and I'm on cruise control, the cruise control stops working as well. I then also can't turn it on. There are no errors or codes in the logs. It's been thoroughly checked by Skoda and independent garages, as well as my self. The issues were before doing the following work on it, but after this, are still there. Changed: - Full timing chain kit (not linked to it, and the issues were before changing), waterpump, etc. - New Clutch and brake sensor - New tires (old & new - no difference) Any ideas? I'd love to get it working again. I think the dropping of the cruise control is more a result of the issue (the issue being not recognizing which gear it's in).

Newest update: Issue is still there. Headquarters advised to replace the Clutch sensor & the brake sensor. Another thought; would it make sense to reset the ECU? It seems like the ECU doesn't understand which gear it's in, so maybe a reset might help with that - relearning the new values? Will have to postpone the diagnosing and everything for about two weeks, lot's of traveling upcoming. So then I'll probably try to get the sensors replaced and reset the ECU.

After noticing quite some wind noise when driving with the roof open, I found out my Yeti has a wind deflector on it. However, it seems to not be fully working - as it doesn't open or stay up after opening the sunroof. I guess some spring is not loaded, broken or missing. Does someone know how this is supposed to work, and which part I'm missing (or can add to it to make it work)? By hand I can open it, but then it also doesn't stay open - there is no pressure to really bring it up. Thanks!

A failing sensor still would make sense. Maybe the transmission speed sensor, or the neutral sensor. But it doesn't give any engine codes or faults to the ECU weirdly.

Hmm interesting. Did it also do it like in 6th? As it is first recognizing it, it just stops after some time to recognize it.

Okey - clear with the ECU. Makes sense yes. The sensors where the first thing I thought of as well. It has been checked (by reading the computer), and they don't give any faults. And a weird thing for me is that it only happens in 5th & 6th. I would expect a failing sensor to do it in any gear - not only higher gears. My clutch has not been changed as far as I know. I'm a second owner so can't say with 100% certainty, but I think it's not been done. Cutting the master cylinder apart sounds pretty intense to do haha. Regarding the clutch pedal actuation - yes, thats perfect. No sticking down, returns completely by itself to the top position. There only is a little 'click' sound if I press the pedal all the way down, and release it. It sounds more like a little plastic part hitting somehwere. Regardless of pushing it deep or not, the gear indicator behaves the same. No, also with calm driving. That sounds like a complicated system - but no it happens with it at any speed, with normal driving. How I replicate the issue on my test-drives after the garage: Test 1: -> Drive 60km/h, constant - in 4th, then shift to 5th gear. Result: -> Gear indicator (on the screen), flickers between 5th and 6th gear, not being sure which one it's in. And then stops indicating the gear. Test 2: -> Go to the highway. Drive 120km/h, constant in 6th gear. -> Put it in cruise control -> Screen will still show it's in 6th gear -> After some time (changes on how long it takes, sometimes quick, sometimes it stays good for a minute or 2), the cruise control will drop & the screen stops indicating the gear. This happens at the same time. The few things that make it a weird issue for me to really think towards sensors; - 5th gear is regardless of speed where this happens. Also at 120km/h to 5th gear, it still flickers between 5th and 6th to then show nothing - 6th gear works for a while, but then stops as well - 1 till 4th gear are perfectly fine.
