fortune82 Posted October 14, 2010 Report Share Posted October 14, 2010 One for the mechanics I think Basically I bought an 06 reg Octavia 2.0 TDI 6 months ago. The car goes like **** off a shovel and gets 55 odd mpg, cant complain. Every couple of days the car does a "judder" when at idle in neutral. It came with a Skoda used approved warranty for 1 year so I returned the car this week to see what was wrong. My mate who is a mechanic said it would prob be a faulty injector or the wiring loom in the head causing a misfire. When I picked the car up after it had been in they said they were none the wiser about the judder but that my turbo was on its way out. They said they know this because of the noise it is making! It makes a bit of a whine at low revs but has done since I bought it. Guess What...the turbo might not be covered under the warranty as it is "wear and tear"! Basically am I being fleeced? can you really tell if a turbo is going by the noise it makes? The car has done 53000 miles by the way. If I was to say dont replace the turbo and it went at a later stage would it cause a big problem ie additional damage? Thanks Quote Link to comment Share on other sites More sharing options...
silpig5 Posted October 14, 2010 Report Share Posted October 14, 2010 what sort of dealer did you buy it from main dealer ? what sort of warrenty? all turbos whine btw . from what i recall of our warrenties , turbo failure is covered as it is NOT a wear n tear item .

4eyes Posted October 14, 2010 Report Share Posted October 14, 2010 Skoda main dealer. They mentioned something about carbon on the vanes? Warranty is Skoda used approved Personaly I would not worry until it does goes. As said, all turbos whine. When it goes you will know by the big ploom of smoke to get from the exhaust. The vanes they mentioned are the ones that control the geometry of the turbo inake to make it spool up faster at lower revs. A good Italian tune is required every now and again. A good blast on a quiet road to clear it's throat usualy does the trick As for the judder it could be any number of things. If the injectors have been checked then have a look at the egr valve. I can't remember if their vacume or electronic on the vag engine but if their vacume check the hoses. A bad vacume on the egr can cause that kind of judder.

Tam Posted October 14, 2010 Report Share Posted October 14, 2010 Get it checked NOW I just blew a Turbo on a 2.0 TDi Audi 2005 with 50K lucky it never took the rest of the engine with it Quote Link to comment Share on other sites More sharing options...
unclemicky Posted October 14, 2010 Report Share Posted October 14, 2010 Had a Luguna 1.9 TDI , what a pile of rubbish , the turbo started to whistle an then bang , there are Laguna's an Scenics up and down the country with blown engines , what happens is that the seals go and the turbo sucks the engine oil and uses it for fuel the only way to stop the engine seizing is to put i in 5th or 6th , hard on the brakes and let the clutch out , Quote Link to comment Share on other sites More sharing options...
shaun4860 Posted October 14, 2010 Report Share Posted October 14, 2010 (edited) Its the same as vw's/seat's.... does it just do it on idle? Try the diesel particulate filter when the carbon builds up.. the engine tries to burn it off, it feels like a rough tickover.....(there is a technical term for this) try taking it for a run around 60mph for 20 minutes and see if its any better..... shaun Edited October 15, 2010 by shaun4860 Quote Link to comment Share on other sites More sharing options...
Dave-G Posted October 15, 2010 Report Share Posted October 15, 2010 (edited) If there is a problem with the turbo variable vane actuation it will show as a limp mode (cut back in power) after continous good - but not thrashing acceleration from 30 mph in 3rd gear for 7 seconds, preferably uphill. If the amount of boosted air pressure delivered is not within a tolerance of what has been demanded the ECU detects overboost (dtc code 17965) or underboost (dtc code 17964) and reduces the fuel amount if either error is evident to protect the turbo and engine. Do you hear a small "pop" under the car about a second after you switch the engine off? It sounds rather like the "pop" you probably learnt to do pulling a finger through your lips as a kid. If you hear that pop the turbo actuator is working - and it's a good idea to listen out for it every time you stop the engine and excercise it occasionally by stopping and restarting the engine when hot a few times. The PD engine indeed has a known issue with the electric wiring loom to the fuel injectors in the rocker cover - I'd be trusting your mechanic more that the dealer on this. First thing to do is find someone with Vagcom software to scan it for fault codes. Here's a result from a Google of "wiring loom PD" http://www.ukpassats.co.uk/phpbb/viewtopic...05&p=208843 A quick Google of "17965" will find reams of information for the turbo - which does not compare with your description of the issue. I'd suggest you get a pot of tea set aside. Edited October 15, 2010 by Dave-G Quote Link to comment Share on other sites More sharing options...
wyatt Posted October 15, 2010 Report Share Posted October 15, 2010 Get yourself on here: http://briskoda.net/ Loads of good information. Although I can't find the details of the warranty online, I'd very much doubt that the turbo would be excluded under wear and tear. Check the paperwork that came with the car! If you can get it in writing that the turbo needs replacing then they'll have to do it now they've found it. Quote Link to comment Share on other sites More sharing options...
steyrman Posted October 15, 2010 Report Share Posted October 15, 2010 BMW 320d turbos are no different its a common fault mine gave no warning just loads of smoke- new turbo and exhaust no more BMW for me Quote Link to comment Share on other sites More sharing options...
4eyes Posted October 15, 2010 Report Share Posted October 15, 2010 BMW 320d turbos are no different its a common fault mine gave no warning just loads of smoke- new turbo and exhaust no more BMW for me Youll always get a bit of carbon build up in the turbo. Its only when this gets too much that the car will drop in to limp mode. A good clean will sort it, but beware - the stealers will try telling you that you need a new turbo instead of cleaning it. Its just easier for them. Thats why a good thrash every now and again is good for them to shift all the c**p out. They may just be saying its starting to build up a bit, so without looking its hard to say. when the car uses the oil for fuel, the oil thats got past the bearings, then yes your right - you have to stall it to save the engine. But leading up to this you should notice your car starting touse more and more oil. That and blue smoke on start-up, so you do get a bit of warning. as for the BMW's; the old vacume controlled turbos were rubbish, they failed all the time. The newer electronicaly controlled ones installed from 06/03 were better. The only thing that let them down was the crank case breather. BMW updated the breather to a vortex one later in 06 I think. That helped prolong the turbo by not blocking so easily. Thing is, even though they charge £300+ for an inspection they NEVER change the crank case breather. You have to ask for this and pay more for it. You should get it changed every 40k on all cars really. Quote Link to comment Share on other sites More sharing options...
decoying mad Posted October 15, 2010 Report Share Posted October 15, 2010 we have all skodas in our buissness mate and turbos do go.dealer price is £1000 plus a local vw specialist charges us £600 with a years warranty just hope it doesnt disintegrate and take the intercooler with it ps we have at least 5 with noisy turbos and there is nothing wrong with them at all. and by noisy i mean it sounds like you have a police siren behind you all the time 1 more point turbos are not classed as wear and tear :unsure: :o Quote Link to comment Share on other sites More sharing options...

It feels like it is only running on three cylinders. If I raise the revs slightly (100rpm) it smooths it out and it only ever does it at tickover. The car has never shown any hesitation accelerating or maintaining a steady speed. Quote Link to comment Share on other sites More sharing options...

As far as I was concerned it was a characteristic of the engine? The car uses no oil at all and there is only smoke when you floor the accelerator, nice black stuff!

shaun4860 Posted October 15, 2010 Report Share Posted October 15, 2010 (edited) mine doesnt..... 06, 2.0 turbo diesel seat, so similar to yours....55k on the clock. if i have chugged around for a long time then boot it, i get a little bit of grey smoke for a couple of seconds.....looks like old cobwebs..lol after that its clear as a bell.... im suprised yours doesnt have a DPF seeing as they are the same engines......mines the 170BHP flavour mind, if mine starts to "fill up" it sits and vibrates on tickover.....touch the throttle and it goes away, sounds so similar to yours, but as i said, after a run above 50MPH for 20 mins or so it clears itself. shaun Edited October 15, 2010 by shaun4860 Quote Link to comment Share on other sites More sharing options...

jacksdad Posted October 15, 2010 Report Share Posted October 15, 2010 Has it been serviced at a reputable place since new? Carbon fouling on such a low mileage engine is unusual to say the least, but could be caused by using cheap non-synthetic oil, which would indeed clog the vanes on this type of turbo: its vital that the oil is changed as recommended, and with the correct grade! Some of these motors run on just 4 litres, so it soon 'wears out'. Just think, a turbo spins at around 200,000 rpm, and can get red hot, its also vital to let the motor idle for a good 30 seconds before switching off, to allow the turbo to slow down whilst the engine is still pumping oil. If the car has been run at high engine speed then turned off right away, the turbo will be shot, and is usually not covered by warranty for this very reason. I've worked in the motor trade for over 30 years and just about every turbo problem I've seen was caused by neglect Quote Link to comment Share on other sites More sharing options...

It is definitely a good idea to idle for a tad before shutting down if you have just blasted up a hill or something. My Galaxy (VAG PD engine) smokes big time if I floor it in a race off the lights for example. Edited October 16, 2010 by Dave-G Quote Link to comment Share on other sites More sharing options...

I actually know the guy who owned it before me by chance and he certainly doesnt thrash around. My daily drive is 54 miles on fast A roads about 55 - 60 mph. The last 5 miles are about 30 mph so this should allow the turbo to cool. Quote Link to comment Share on other sites More sharing options...
Dave-G Posted October 16, 2010 Report Share Posted October 16, 2010 Sounds like your mechanic is on the ball mate. I'd be getting him to have a fiddle with the injector loom as a fisrt point of call as by your description there is nothing wrong with the turbo - and the dealer stands to cop for a good few quid claiming a turbo was replaced rather than the loom.

I'd be getting him to have a fiddle with the injector loom as a fisrt point of call as by your description there is nothing wrong with the turbo - and the dealer stands to cop for a good few quid claiming a turbo was replaced rather than the loom. My take on the situation is that the turbo is fine. Main dealers are after all fitters rather than mechanics. I reckon they will try and do a new turbo under warranty which will make the dealership a few £££ then try something else if that dont work etc etc. As my mate has said if they will do it under warranty let them! Then take it back when it is still juddering! From all I have read on various other forums and a drive round with my mate in the car there is nothing to suggest the turbo is on its way out Quote Link to comment Share on other sites More sharing options...
