Just take it to a Vauxhall main dealer.

If the only issue was a blown turbo, then a new turbo and cleanup of associated pipes and coolers should have fixed it.. unless the guy doing the work was a moron.

Plenty of them around doing turbo replacements.

Problem is...a lot of those morons reside on main dealers ! Perhaps more so than elsewhere. Although he may get lucky...probably cant be any worse than whoever he's been using so far.

We went through everything only two things that i can think of right now is that the turbo i got was faulty or the ecu got a problem. As sometimes the car has boost and sometimes it aint got no power i can i can hear the turbo spinning as soon as i start up the car the turbo makes some weird whining noise.

No...you really have not went through everything....because if you did the cause of any problems would be quite obvious.

And when people make claims of a faulty ecu, for no reason whatsoever...it's usually because they're also clueless about the mechanicals...so the easy thing to to is blame the ecu...sure may as well throw more money after bad replacing st that doesnt need replaced because the mechanic is clueless....

Recall what I said right at the very start of this saga ? It's all coming true.

Just find a mechanic with a brain.

Were the oil feed pipes to the new turbo cleaned or replaced ?

If not and they were clogged with solid oil deposits ,it's probably ruined your new turbo.

A new turbo should not whine.

Generic OBD tools can often give wrong codes or misleading codes.

But yes it is possible there is overboost...and underboost and many other things.

Hence why it would only take a competent person a few short minutes drive logging with VauxCom or similar to get a full picture of what is going on prior and when such a fault occurs.

It is a little louder than would be liked, but largely irrelevant at the minute.

Do some proper bloody testing or go to somewhere that will instead of all this nonsense sitting revving it in the driveway. That certainly wont fix anything.

What he ^^^said .

I think the forum cannot fix this.

And the correct answer is find a competent mechanic .

Or is "the mechanic" the OP ?.....scratchchin

save/record the datalog of engine parameters whilst driving.

Hopefully whoever as paid the money for Vauxcom, knows how to use it and interpret the live data.

Possible...and would only take one of these dumbass "mechanics" 5 minutes to check/replace and filters are cheap anyway.

Although given the work already carried out I dont think it will be. The problem is more likely to have been caused by one of the incompetent fools working at the car already than just a random problem.

But if they had carried out any of the tests I'd already said...it would be easy to know what is going on, but clearly they have not.

And feck knows what state the cat is in after one of those morons destroyed that expensive part without the owners permission by punching a hole through it. I wonder did they ever compensate you for that damage ?

Blocked filter gave very similar symptoms on my Kia diesel. Black smoke, high fuel consumption, turbo generally wouldn't kick in and often the engine would cut out at 3,000 rpm. Kept going into limp mode, then clearing up, then coming back again. Stumped me for a bit because it's my first diesel and I'm more used to petrol engines but our friendly MOT guy guessed filter when it filled his MOT bay with black smoke and failed on emissions. He plugged in his code reader and confirmed a fuel pressure issue. Filter was an arse to do because you have to remove loads of stuff to get the filter housing out and then it transpired the filter I'd been sent wouldn't fit into it. Correct fuel pipe thread but about 3mm too big on diameter so we had to slice open the sheet steel filter housing with an angle grinder and spread it open a bit. Old filter was chock full of black crap when I gave it a shake and car ran perfectly as soon as the new one was in.

Blocked filters can cause a huge range of issues on modern diesels. Also just because the turbo had to be changed doesn't mean that any other problems must be something to do with that. Correlation does not equal causation.
