Thanks. I didn't think of real time values! Will any cheapo Bluetooth OBD reader read that, or is there a specific one ?

This video found on youtube shows exactly what I get on my car if I open the fuel cap with the engine running. Same tapping noise, and smoke (or is that vapour?) Funny enough I've never done that to another car but I did when viewing this one, but it's quiet when capped so I assumed it was alright. This clicking noise comes when I switch the thing off. Always 4 double clicks, and 1 faster double click. What is that noise? And this "whining" noise (around 10 seconds into the video) , quite audible to me, and which I haven't heard in any other car I've tried, comes on seconds after starting the engine, and stays steady even during driving, until I switch off. There are no codes from the OBDII. 1. If there is anything I should look out for or test to troubleshoot my turbo, or my "underboost?" situation, please let me know and I'll take a video. 2. The only other problem I've noticed in the car is the blower fan only works on 4 so probably needs a new fan resistor. 3. And the battery light on the dashbord is always on but very faint, like it's not really on but I can see it. 4. Start-Stop is always "not possible", but I did some reading and people are saying the battery can pull this system off for about 3 years then a new battery is due. Again, a newbie here to both Fabia and the Start Stop. 5. Last problem I just remembered: a bit of a squeak from rear wheels I can hear at creeping speeds, without applying brakes. A binding caliper, or is there energy-harvesting technology on the wheels that could do that? Please help me find any trouble in the car. I need diagnosis tips Ready. Set. Go.

Dear all, Good to see you again. I'm coming from a 2009-2010 Octavia II 1.6 TDI Greenline, turbocharged, which I've had for 4 years. Just got my 2nd car: a 2011 Fabia II Greenline 1.2 TDI. When I tested this car upon purchase, I didn't know much about it, like I didn't know it has stop-start, and I didn't know it had 3 cylinders, and I wasn't sure it was turbocharged. But it drove and I was in urgent need and I've been looking for a car for 10 weeks so I ended up buying it and who knows, I may have overpaid. The point now is. I'm test running the car and there is one thing I noticed which I didn't like (besides the noise of course, damn that engine is noisy). Sometimes when I get near a stop, like at a traffic light queue, or when I'm emerging out of a junction, the engine seems to refuse to pull for a short period. I might even end up stranded in the middle of a lane until it pulls through, and that is mostly in low gears due to the situation in which I noticed this. It's been bugging me all day, but it kind of dawned on me tonight. Could my Turbo be shot? I confimed via google that the car is indeed turbocharged. I don't hear the turbo sound that the Octavia makes but they are two different cars after all. How do I confirm if my turbo is working? And if it's not that, can you think of anything else that does it? Does your car do what mine does? And finally, there are a few clicks and whirrs I want to ask about. If I upload videos to YouTUbe, can you help me recognise what they are?

A little update. My neighbour, who's driven Audis for as long as I've known him, has had a chance to use my car for a couple days. I asked him if he feels it's underpowered or heavy, and he said it feels fine. I suppose the culprit in this story may have been a low tyre pressure, as I found one tyre losing pressure after a while. Thank you so much for all the useful information, may this thread be informative to others for years to come.

New filters every service. New ones have been installed last MOT, about 9-10 months ago. Nothing in the weather this year have clogged anything. I can check but 100% sure the air filter will not be a source of any issues here.

So in short, getting the fix done by them is not recommended. I'm sorry I cannot go through any reading material at the minute, can you give me a summary for information? I'm not aware of any updates after the time they sent me that letter a couple years ago. It does say optional on my letter. I see what you mean now. I may give it a test. I've now tested the above suggestion for brake caliper binding, and there seems to be non. I could make the car move on a flat surface while in neutral by turning the rear wheel with one hand. Pushing that wheels, the car keeps moving for a bout 50cm. Coasting the car at walking pace also yields no sense of braking, neither at the front nor rear. The one thing on my radar now is the EGR delete (with EGR simulator). I'd attempt that on this car for for £30 if I can find a kid cheap second hand, but not for £100 as it's not a priorty. The car is nearing 200K and I want to minimise risks of failure.

Thanks for the replies all! I didn't see my email so didn't realise there were replies. This is a very good suggestion. I'll try that out. Which remidns me, last MOT the mechanic did mention something about one caliper probably binding or something, he pry-barred it or something (I didn't hear or see well) and since then I got some slight squeaks every now and then. Now I don't drive that car anymore so can no longer tell, but this is definitely worth looking into as a potential culprit. I do take the car out on a motorway every now and then. Like I said, 4 hours on a motorway not too long ago, and over 40 minutes of gear-4-driving (2-3k rpm) on a motorway. I'm pretty sure the DPF is clear. The EGR less so. I've been considering using one or two of those EGR cleaner spray cans that go into the intake while the car is running. Worth a shot, or... see comment at the end? Don't you mean they are similar to the Vs and different from the Citroen? My previous Citroen was light as air (not in a pleasing way) my current Merc A180 is light as water (in a pleasing way) - I haven't driven V's, but just test driven a 2013 passat recently and it may not have been far off the Octavia. Still think the Octavia is heavy-steered to an unpleasant degree. What would that help? No I haven't. I don't know which engine code I have yet. Haven't looked. This is a complete blanking that tricks the system into thinking the EGR is still present and is funcitoning happily, correct? I'm not sure I want to do that to my car even though I understand the benefits. I have kind of just kept it as stock as possible all this time. Not even taken it to do the emissions test. Follow comment below. I haven't done the emissions fix, why would I? How would I know they wouldn't install some other bug or claim my car needs something it doesn't. No I don't trust dealerships with anything. But this is very interesting, you are saying that if I get he fix done and get EGR problems as a result within 2 years, they would replace the EGR for me? That sounds like a free EGR replacement opportunity.

Hi all. I did a quick search but this is general so keywords won't help. I'll try explaining and giving any history and hope for some informed insights. I have an Octavia II 2009-2010 Greenline 1.6 TDI, 5 speed manual gear box. Got +190k miles. Practically one owner before me who used it on motorway. Everything about this car is perfect. I've had it for 4 years with no big issues. Changed a bulb or two, and a tailgate strut. Don't think I did anything else other than regular servicing. Car has been serviced regularly all its life. One thing I noticed when I bought it was that the steering wheel felt a bit heavy (moving from a Citroen C3, I assume this is just car-to-car difference), so moving on. The one thing it does is if you move in slow traffic, or keep engine revs fixed at a low gear, say for a minute, it says engine faults, and you get a glow plug light on the dashboard. Which clears when you turn the car off and back on. An OBD scan at the mechanic says it's the EGR flow is insufficient. My mechanic adviced that the job is not economically worth doing, and that I could leave it as it is for a while - do it if I really have to. I've now done a rescan and got the same result. No new codes or faults coming up. Now, both myself and my wife feel the same thing: it feels like the steering is a tiny bit heavier, and that the car overall feels a bit heavier. Still works and no codes reported on OBD, no visible issues, but just car feels like it needs more effort to move, for maintaining speed going uphill, moving from a standstill, or taking junctions. Tyres are the right pressure, before you ask. Our normal in-town driving, we never reach 3k rpm or over-rev. Mostly 1.5-2k rpm. Consider which engine we have. Can I have your insight on this? Is it just us or are these supposed to have firm/hard/heavy steering? And what would you think if the car starts to feel like it needs a bit more effort to roll, but no faults come up.
