Ive only had my octavia for about 6 weeks and in general been more than impressed with it. It's a 2001 TDI 110 ASV with 65K and full Skoda history. The problem is, this is the first one I have driven and if you have a window down or the sunroof open the turbo is very noticeable between 1000 and 2000RPM (sounds like a big turbo spooling up! ) then after 2000 you dont really hear it. The engine pulls very well accross all the revs and is stupidly economical but I just don't know if its suppose to sound like that or if its telling me the turbo is on it's way out. Anybody had this and can put my mind at rest or tell me Iam doomed!

I don't hear mine much, but mine has sticky vanes problem I used to hear mine with the window open when driving down a road with houses on both sides, but it was never massively loud.

I can hear it all the time between 1000 and 2000 with the window open, but nobody else who's been in the car had noticed till I pointed it out, but half think because it's new to me I am listing for problems but on other hand it does seem very noticeable to me. Doesn't effect it in anyway, but didn't want to ignore a problem developing if there's something I could do to save my turbo!

I'd certainly expect with the lowish mileage, one owner from new and full Skoda history it should be in tip top shape as the rest of the car is.

I test drove a 90bhp Octy estate TDI at a Skoda dealer in, erm,,,, 2007 and on the test drive the turbo had died.

It had covered 66k with fsh. They replaced the turbo before we bought it. So it wouldn't be unknown for a turbo to die at that age. Having said that, I now have the 130bhp PD engine, have had it since 48k, now on 102k and no turbo problems at all (touch wood!)

A friends of mine has got a 130 PD Passat and the turbo on that is a lot quiter but he thinks my engine is smoother and quiter in general than his!

I'll just have to see what happens with it, as there's no smoke and certainly runs spot on, was just hoping someone was going to say don't worry they all do that!

We're on our 2nd Bora 130 TDI Sport. & both have been quite noisy on spool up. I think it's normal.

The turbo only starts to work effectively above 2-2.5k revs, unless you also have the sticking vanes problems like mbames in which case it is working all the time - I know because I wondered why there was no turbo kick as it came in until I had the vanes cleaned mechanically on mine (same engine as yours and at 56k miles).

On a previous turbo diesel car (not VW group and mileage ~120k miles) I had a noise like a police siren as the revs increased. It became so bad eventually that bystanders started looking. However, the noise started initially only at low revs - gentle acceleration in second gear. Worth keeping an ear on the noise. If it gets worse or happens at higher revs then it is turbo bearings and a new turbo required.

Having said that, have you you checked for leaks in the system?

Mike

I haven't checked as such for leaks, but it doesn't sound like when a trubo hose is split, to me it just sounds like a big tubo spooling up. I assumed it didn't have a problem with sticking vanes as you can give it full throttle through every gear and it never brings em light on??? It may just all be me looking for problems but just sounds louder than any TD's(non skoda) Ive heard before.

I know its not related but twice now from cold when Ive started it, it starts first time then instantly cuts out but restarts straight away when you try, is there a common air leak can cause this???

Mike

it just sounds like a big tubo spooling up.

Mike

I have absolutely no discernible turbo noise on mine at any time from inside the car. Do others agree? (ASV engine on the Elegance model)

If you had sticky vanes, you would find the engine going into a reduced power "limp home mode" when giving it some welly above 3000rpm. The temporary fix is to stop, turn off the engine and restart.

With the windows up I definitely can't hear mine. Down and close to some buildings then up a narrow road I can.

Stop? nar, I just cycle the ignition and keep my forward motion, don't want to go wearing out the brake pads I really must sort out my turbo soon, it is really starting to annoy me.

some times i can hear my turbo from inside, just a quiet whistle whilst it spools, with the windows down i always hear it when accelerating hard! done 188,000 miles now, still pulling strong and will for a whilei hope (touch wood) i had a problem with sticky vanes a few times but that was solved with a few strongtanks of Red-Ex!

I've also got a 1.9 TDi Elegance on the ASV engine, from inside mine I can here a certain amount of turbo noise, sort of a breathy whistle as it spools up, but that's about it. I assume this was normal, my previous TDi cars have done it too.

Just a quick aside on the turbo, the other week I had to replace the aux tensioner, which requires the dismantling of....well the car would be easiest, but I managed to keep it down to everything on the left hand side of the engine bay!

One of the million items I had to take off was the top intercooler air pipe. I noticed that where the rubber pipe attaches to the metal at the back of the engine, there was quite a lot of oil residue inside. Is this normal/ok? The engine doesn't seem to be consuming oil and appears to do everything I would expect.

That is from the breather on the top of the engine, circulation the warm oily air back into the system, near the EGR assembly.

Have a search, it has been covered quite a bit. Some people (me included) have cleaned out our EGR assemblies because they get clagged up with oily air and exhaust rubbish and in some cases can cause the anti-shudder valve to remain jammed shut once the car has stopped for a short while (such as filling up with fuel after a long drive).

Dirty inside:

My pictures show a fairly clean one, some people have reported the internal dimensions to be a fraction of what they should be, thus meaning reduced airflow....

Thanks for that.

Don't think mines even as bad as the oen you show, was more wondering if it was a sign of problems. When it comes to cleaning, would it only be that assembly or do you need to go further?

Tom

You can just clean that assembly or you can do the manifold thing too (but you should ideally have a spare gasket to hand).

Thanks for all the replys I think I'll stick with me being over precautious and looking for problems. The only thing Ive really done so far is fit an EGR blanking plate as Ive done this on my previous cars and dont like the idea of EGR valves, when I fitted It I did have a quick look at the valve and didn't look to bad so not sure if it's been cleaned sometime in the past but I gave it a wipe out anyway.
