Help, loss of power

[mighty t]

Can anyone help please.
on way back home this morning 200 mile drive. Everything running well stopped for coffee 40 mins. Drove off onto 303 let all warm up again, went to overtake in 5th about 70mph & realised had no real surge of power & boost not going above 0 bar, could only hear slight whoosh/hiss from near side filter. Filters are bulk head mounted. Engine is running as normal but seems like rear turbo not working.
Any help much appreciated.

Cheers tux.
Recently fitted new inter cooler but checked all hoses when noticed power loss all was fine.

Actuator arms still on the spigots?

Not exactly sure what I'm looking for, can you explain in laymen terms.

Ok checked actuator, arm is still connected & sprung shut however arm seems quite loose in actuator like it's not connected properly. If I start engine & rev should arm move because it's not. I can't quite get to or see the other one to compare.

Thanks
Done more checks all pipes are sound & secure, actuator pipe is connected & even if I rev hard the actuator pipe doesn't move, the gauge doesn't move either. Taken out for short drive & gauge still not going above 0 bar.
Is this indicating faulty actuator or could it be turbo.
Thanks.

Finally got round to having a proper look over the car earlier this evening at a friends workshop with his help,
First off checked all the hoses all secure & no splits.
Disconnected vacuum hose from tee piece feeding rear actuator & pumped small amount of air into it, enough for the actuator rod to move. Damn was hoping that was the culprit not too expensive to replace.
Then did same test on front one just to be sure, that too was ok.

Ok now thinking have buggered turbo.

Disconnected air intake hose to turbo compressor & fired it up, could see turbo veins spinning & wind down freely, all veins looked fine.

So turbos working, actuators working but have big loss of boost & can't hear noises from drivers side bulkhead filter.

Now thinking exhaust turbo blocked somehow, maybe catalyst broken down & restricting exhaust flow. Could this be the cause, the exhaust is standard on a 03.

So decided to call it a night & have a think over a pint.

I drive the car out of the workshop down the road sensibly but still can't hear any hissing & whooshing & I normally can even at low revs.
I Pull out onto a clear main road & press the loud pedal all the way, about 4500 rpm the rear turbo decides to play ball & catapults us like I've not been before. Holy s..t wasn't expecting that.

So my turbo is now working, did loads of variables & it's running as it should. I'm none the wiser as to why it packed up really but I'm just glad it's working ready for a good weekend of blatting.

Happy MT
