Hi folks

The car i am going to talk about is my daughters and i do not no exactly what happened but here goes the car is 53 reg 1.9 Octavia diesel 96000 miles110 DT redi

She tells me they were driving along and she heard hissing noise when is under load very little power I was not able to check car myself so sent her to my local Skoda garage who informed my turbo hose had blown off causing engine run in low power mode.That sounded reasonable so they said it needed a new pipe as it had gone slightly soft so they put a hose on tried it still no power so they said turbo is faulty so they removed it and found the boost valve stuck in the boost position. I am a diesel fitter by trade and most of my time has been with truck engines So i have no experience with VW engines

How ever i have been and inspected the turbo and it looks to be in very good condition not passing oil or excessive play in rotter shaft ,the only fault i could see is that the boost valve will not return from the boost position correctly I am wondering if the boost valve caused the hose to blow of or could there be another reason ,I have heard people talking about breather hoses causing this problem As far as the turbo is concerned it is an insurance claim with the RAC scheme and they want the turbo to be sent to turbotechnics for there report on the the turbo before they will pay out £1000 fitted

As you see i am not convinced a new or rebuilt turbo is not the whole story experience tells me there is more to to it yet

I am sorry that i have had to bore you with along essay but thats the only way i feel anyone can have fair chance to help me

So any information from any body who has had similar problems and how they solved it would be very useful and I would be extremely great full

Thanks Skodaman61

Sounds to me like a classic case of a sticky vanes in the turbo. If the turbo is off the car, and you feel willing, take it apart and clean in the vanes.... have a search on here it has been covered a lot. Searching for VVT (V V T, not WT!) and that should guide you in the right direction.

I have Y plate 110TDi (same as you daughters) and mine suffers similar issues with sticking vanes.

Generally Skoda say the fault is unfixable, and suggest a new turbo, although several people on here have had good results with cleaning it up.

It's highly likely that the variable nozzle has seized up, this is what is controlled by the actuator and is housed in the exhaust manifold. When supplied by Skoda a replacement turbo will come attached to the manifold. Despite the turbo itself being OK, a dealer will only replace it with the manifold as that is how the replacement parts are listed. The turbos are usually exchange units, so they can only have it if they pay the surcharge.

Hi folks

I would like to thank all who are helping me to solve the above problem thanks from skodaman61

Has any one had dealings with insurance companies as regards above problem i spoke to turbo tech about my turbo fault they say it is probably caused by the car doing short hops like the school run etc and the engine is not warming up enough to burn the sticky waste away witch is what some of the members are saying and i have to say i probably think along those lines myself

So i feel this could be a turbo design fault when Vw Skoda in my case as when they sell cars they do not say do not by our diesel range if you are only going to do a lot of small hops because we would expect the turbo vanes to clog up.

In fact just the opposite they are advertised as family and thats what many families have to do

So i feel i should have a good claim against the RAC

Does any one agree with me or have very different views i would be very interested to here what other members have to say on the matter.

Thanks Skodaman61

If the turbo is covered under your policy, you shouldn't have too much trouble claiming for it. If it's not listed as something they cover, my guess is that you may have a little bit of a fight on your hands.

Suffering a few turbo issues at the moment, so I have a lot of sympathy for you :p

Best of luck with getting it sorted, and like I said, if it's covered in the policy then they don't have much choice but to pay out...
