Fairly straight forward as long as there not rusted in. On the octavia theres one allen key/torx screw(cant remember off hand) that holds them in place (make sure you clean it out so you get a good depth of grip) from memory you can just get to them behind splash guard. Soak them for a few days in penetrating oil and gently wiggle them while pulling upwards. Check condition of wiring etc before hand just in case its wiring/connector related. Alasdair

Hello everyone! I bought my first car a few months ago, and I have been loving it! The car starts and it doesn't beep at me and there isn't any systems I want to turn off every time I start the engine and the controls are all physical buttons and its a small car but it doesn't feel small when when inside. Originally I planned to keep the car in great condition and keep it for as long as possible, especially with the current trend of crossovers and SUVs meaning bigger and bigger cars are on the road and I'm not interested in in those massive ugly things. I could go on with how much i like this model of car, but I do have some minor issues with the car and I am not sure if they are worth fixing to keep this car on the road for a long time, or to leave it alone and save that money I would spend to repair it to buy a better condition car in a few years time? The issues I have with the car are as follows; Dent on the roof rail and on roof panel, quoted about £500-£600 to fix it Occasional interior rattle on the passenger side(left hand side), not yet found the cause of it Driver side electric window works, but the sync is lost every time I shut the car down, so i have to hold it down to open the window fully Clutch feels high compared to the car I learned to drive in (crossover Ford Puma) but it doesn't feel like its slipping Some tiny paint chips on the bonnet with sone rust on it Ive had the car checked by a VAG specialist garage to diagnose the vibrations (as there was some at about 70mph), and couldn't find anything wrong, they say the car is in good condition for its age but possible cause would be the "cheap tyres" having thin walls I put on it (I didn't think they were, but they are 195/55R15 85V LAUFENN S FIT EQ+ if anyone is more knowledgable about tyres) and to "just enjoy it" What are your opinions? Would you fix this car up to keep it for a long time like I originally wanted to? or would it just be a waste of money in the long run? Car also came with loads of paperwork with the service history, so much so I bought a ring binder to organise it all, I am the 3rd owner and its always passed MOT and has been serviced by garages Thanks for your time!

Thanks for the replies. Is replacing the sensors a garage job or is it straight forward?

indeed🙃

Check timing cover and also PCV. Cant think of anything else if the engine block has no signs of leaks. Have a look at the oil pressure switch in case its leaking and oil is traveling down wiring and missing engine block Alasdair

I'll have a look at my car this evening, to see if I can make some suggestions.

No i had an engine oil low light last week and I see engine oil dropping after falling up. Its totally dry on the gearbox side.

Plenty TDI,s (Millions) are on long Service / Variable / Flexible oil and filter changes and used with the annual mileage and usage to suit that and do not use excessive oil.

Could it actually be gearbox oil from the RH driveshaft seal?

Out of interest, how frequent has the oil been changed during the cars lifetime? The long life service plan with 30k kilometer oil change interval doesnt do any good for the piston oil rings in this engine. I would try a forte new generation motor flush with their instructions for an engine that hasnt been cleaned earlier: first drive the engine warm, then 2 bottles of forte motor flush in on the current oils in the engine and with a raised idle speed of 1500rpm, gear in neutral,STANDING STILL, dont move the car, let it idle for atleast 30 minutes, maybe even close to 1 hour. Then shut down the engine and change the oil, careful it will be hot, let it pour out all the way and then if you have any leftover,clean and suitable non used engine oil layin around, maybe pour few desilitres in and watch from the sump plug hole will it come out clean...just a little extra flush to get all the old oil out. Then new filter and good oil like Liqui Moly. Maybe even throw a bottle of Forte Advanced Diesel Fuel Conditioner in the fuel tank to clean the fuel system. This would be my first approach for the problem. If the piston oil rings are only gunked up due to bad maintenance they could possibly be cleaned with motor flush. They could also be seized or even broken so then the flush wouldnt help.

I agree could also be a build up of dirt/rust on sensor tip. Doubt its wiring as both seem to be giving trouble. I would change them. I used Febi ones on my octavia and they werent expensive. Had to change them due to replacing wheel bearigs and broke senors trying to remove them No problems so far. Think from memory they were around £12 each Alasdair

@Erewash100 Have you found the cause for these speed warnings?

New Dacia Spring, sister product of the new Renault Twingo etech, will go on sale in Spring 2027 reportedly. Same small 27 KWh LFP battery and therefore 150 summer range and 120ish winter range so very much inter town or county rather than cross country. Price should be sub £15k. Bigger than the 45,65, 100 old model Spring and 80 hp. Apparently the 100 hp, sub 1 tonne Spring was as expensive as a Gilf GTI to insure ! 12 seconds to 60 in the new Spring. Torque presumably lowish line the power. Weight now over 1.2T but it does look much more sturdy.

Has anyone managed to fit roof bars on a fabia estate without mounting points OR existing roof rails? Seems like best way is to rip the plastic gutter out, fit some old roof rails, then buy some roof racks to attach to the roof rails. I'd like to avoid that. Any ideas?

You have a dying ABS sensor at the back. Maybe two. Scanning with a decent tool will help identify which one.

Battery is new 2 year ago. Abs Intermittent o/s/r wheel speed sensor range/performance Intermittent n/s/r wheel speed sensor, magnetic field low. Intermittent EPB control unit wheel speed sensor implausible. Engine Sporadic database error value received.

I guess you meant 2% petrol?

yes, its roughly 2% diesel. AI agrees with you - harmless. The main worry is lubrication of the pump but at 2% not an issue. No or a beneficial effect on DPF - apparently.

Could be a voltage drop. Whats the condition of battery and also is alternator charging ok. On the other hand my octavia had random warning lights appear some bright and others dim. Cluster needed connector cleaned and reseated. Were there actual fault codes stored to match warnings? Alasdair

@MarioVrs What Superpro arms did you use? I've ordered and received some TRC1070s and now finding conflicting stories about whether they're right for the car or not. Do you still have them on?

Hmmmm - I found nothing definitive on it and thought these were fine. Have since seen your post but then Mario's seem to be fine... MarioVrs' post

Glad its superficial damage and alls well. You were lucky. Could have been a lot worse. Alasdair

Skoda parts list 3 interchangeable part numbers for the 5K0 part, with applications limited to Superb 2, Octavia 2 and Yeti. https://www.skoda-parts.com/spare-part/5k0907659-air-quality-sensor-european-union-38255.html Maybe just buy one of their non-genuine offering?

Having said all that I have 2 trouble codes for the 5F unit, dab antenna both open circuit. Apparently that failing can cause distortion on all audio sources. I have discinected the fakra connector to see if that resolves it bit srill the same, also possible break in door harness can also cause it, so hoping it's one of those that is causing it. Quick look and found a new one but for 75 quid for a tiny little box.

Compression test was good! 13bar in all 4 cylinders. Have put 4 new spark plugs on and just driven to the shops and back with no issues! So it looks like my bro was wrong and it doesn't need a new engine. Perhaps I was lucky and have got away with just a bit of surface damage. Cheers for the help
