Skoda Octavia1.9 TDI turbo boost problem

[Transporter]

id be looking at other reasons why boost is 'cutting out'. wastegate getting stuck open, solenoid not working etc

to me it seems like something that could be fairly simple.

Yes, that's what I think as well. I will see the car in next week or two and we will keep you posted.

Also there is a little known fault in some of the tdi wiring looms which can give false pressure readings, thus thinking the car is overboosting and cutting it out.
Dealers had no idea with my vrs when it was doing it, i have to trawl the net and tech bulletins to find it.
Loom was only about 65 bucks but the labour was 3 hours. I bought the part and told them if it didnt fix it i would pay.
it did

such a simple fix. i bet this one is as simple too. good luck transporter!

Apples and oranges I know but my wife's (expletive deleted) Yaris is same age and mileage as the Skoda, has never, ever cost more than $350 for servicing <snip> Skoda never less than $350 and usually much, much more...

Yaris service schedule 6 months 10,00km vs Skoda 15,000km 12 months? Apples and Oranges indeed.

KM wise we do about the same, and yes in theory the Yaris is twice as often but in reality it ends up being about 2/3 the time. Also, minor dealer servicing is well under $300, only the more major to date have been over. If we'd bought it a year or so later it would have come with $130 fixed price servicing too. I can promise you the cost of ownership of the Yaris is way lower regardless of service intervals, got the bills to prove it. And the ease of servicing is incomparable.

Do I want a Toyota? No. Do I want a better service deal from Skoda? Hell yeah.

Have just been told skoda will extend good will past warranty and supply new turbo Still have to pay labour but will certainly save me lots of expense. Talked to dealer about it possibly being solenoid or some other simple problem but they are saying it's definitely turbo. Will have to wait and see. Hopefully new turbo will solve the problem and get me back on the road.

Great outcome, hope all goes well for you

the vacuum actuator diaphragm is probably cactus and most of the time cannot be bought seperately which means whole turbo has to be replaced

What a joke though....

Turbochargers are so darned reliable, good quality OEM ones dont just go bang (and if they do they usually fill the intake with bits of alloy). So your right of course - this is probably stuck vanes or a bad diaphragm.... but just seems so silly to me that they dont sell the actuator separately through the dealer parts network.

You can certainly get them aftermarket, its just a matter of getting the right mechanic to find it and do the work for you (more trouble than its workth for most people i suppose). I would hazard a guess, though, that the process of replacing and then adjusting the correct preload on the actuator is "too hard" for the modern dealership, and hence the replacement of the whole unit (where the preload is adjusted by the factory - hence the dealer can't screw it up (no offense buzuki!)).

Ahh well.

No its not to hard for us. There is other turbo actuators we replace seperately. And we have to set them up. Some are probably full replacement due to the rods acutally being very difficult to get to adjust.
