I've only to pay for the one I've fitted, thankfully, as I work in the trade so got it through my work, no labour costs either. Would've been a nightmare otherwise.

Yeah going to go once the lockdowns ended and I can travel across the country. I had it mapped before changing the turbo so worried something will now be off, but only travelling through town these days anyway. Cheers.

Just to end this. Put new is20 turbo on, with genuine actuator on it, and actuator worked constantly and nobody could code it in. Fit brand new is38 turbo on with genuine actuator on it, and it's working perfectly. I removed an is20 from the car. Can't explain what happened, or why it's now fixed, but there we go. Presumably car just wants more power so forced me to fit a bigger turbo.

Got an auto electrician out, and he can't find a problem with it at all, but it still fails adaptions. He's now sayings its a problem with my ECU and I'll need to go to Skoda garage to sort it. Madness. Car is costing me a fortune at this stage.

Voltage comes up at 3.802v when idling, which I'm told is within parameters and should allow it to adapt. It just refuses to do so, and comes up saying the wastegate is stuck. Can move the wastegate free with my hand. Trying a brand new battery in the morning, if not I'll just have to spend money on an Auto Electrician to source the problem for me.

Any idea how I can check this? Came from a turbo company in Glasgow I've used regularly through the years without issues. They've sent me two turbos and both do the exact same. Switch ignition on, and actuator starts working back and forwards a small bit. Reading 65% roughly. Its now stopping after a while and I'm getting a fault code saying its stuck. Can move it fully either way with my hand. Got VCDS and it doesn't allow me to do a basic setting for the actuator.

Having a nightmare. Fit a new aftermarket turbo, the actuator is constantly running trying to move and reads as stuck at 65%. Won't adapt. Can move it free with your hand. Get a genuine turbo, plug it in, and it does the exact same. Alternator has now randomly stopped working aswell. New batter fitted. Same issues with both. Only fault code is to tell me the actuator is stuck at 65%, on two brand new turbos. Zero idea where I go from here.

For anyone interested, my wastegate was apparently completely shot and on the verge of disintegrating. Just getting a new turbo.

If anyone has any other suggestions, thinks the turbo fin looks fine, then ill be delighted 😂 Siren noise only appears when starting to boost.

First topic I could fine, but add me to the small list of Mk3 Octavia owners needing a turbo replacement. 63 VRS petrol with 80k miles, started howling like a siren one day. Huge play in the shaft and i think it looks like a damaged fin from the photo I got. Almost £1000 for a new turbo from a place in Glasgow, but they don't keep them in stock, so going to send mines away and hope it can be sorted.

Through my work we've had 4, maybe 5, blocked heater matrixes due to the silicone bag exploding. You have to replace the matrix, header tank, and flush the whole system multiple times to resolve it. Never come across a rusty matrix caused by not having the silicone bag, and honestly I'd be using a header tank without it if I bought a car with one. Thats a really small sample size I've got though.

Why is an independent more like to do it wrong than a dealer?

Just beware that the early mk3 VRS' are lower spec. I've one of the first batch, while a customer at my work has one 2 years younger, and despite both being VRS' his has far more I presume came as standard.

And "well north of 300bhp" in a FWD car is a bit pointless.

Cheers. I'll try and get in touch with the mapper every day from now until Monday, I'm just wanting to confirm with him it's the map causing the issue as he should really know exactly where to look for the issue, and then make plans to go to Skoda to see if they can revert it back. Using my wife's car just to prevent any potential damage so can wait until I can get in touch with him if needs be.
