Those are the results I’d expect. I can’t think of a mechanism where the wastegate would affect the MAF readings.
I thought it was a high MAF reading not a low one?
Good you found the culprit.
Sorry for you, it's going to be a costly repair.
Btw: is this something all of us can expect when we arrive at that milage?
The cat was rattling in the casing wasn’t it, so that definitely needed changing before it disintegrated.
Just imagine what is mere mortals that would have had to pay if we just booked it into a main dealer.According to Jason (who put me in the right direction) it's not uncommon, and it's nearly always bank 1. Go figure...
There's about £50 of o-rings and seals (as well as obviously the manifold gasket), although mostly they are just o-rings and bits so probably utterly un-needed. According to my book, it's 6 hours of labour, but that includes removing the front transmission shaft, which clearly, we don't have.
So for second hand / refurb it's the thick end of £1500 if you want to swap the oil and the coolant at the same time.
*Assuming* this solves it, I'll do a quick cost run down of the entire process, and what money was 'wasted'
I got some new tools, which I won't regard as a waste. Some turbo hoses and clips, likewise.
Much of the parts I can claw back. The DV was way cheaper than ebay, so that can go on there. Similar the cat, which I'm pretty sure is OK, I can probably get my money back on. The turbo can be re-furbished. Either I'll sell it as is, or get a kit and fix it up. Will offset a chunk of that as well.
Obviously the labour to replace the cat is sunk, and I can't do much about the labour to swap out the turbo itself, however, given that I've not had a car break down for 10 years, I'm OK with this sort of cost level.

I have total respect for those of you that have the skills and tenacity to work through these things yourselves![]()
To be clear, I am not having a pop at the cost of professionals, more that they would need to be paid for all the investigation and “trial and error”.To be fair I bet there's people on here earning £1200 a day or being charged out at that fee in consultancy rolls.
Unfortunately there's no quick and easy diagnosis Sam even if you've encountered the same problem before.To be clear, I am not having a pop at the cost of professionals, more that they would need to be paid for all the investigation and “trial and error”.
It was unlikely that they would ag e gone for a “first time” diagnosis and fix,

Electronic diagnosis computers can lead you up the wrong avenue.
In the past we would use a length of heater hose a long screw driver and our ears.
Yay!!
Is there enough length in the loom to change the maf plugs so bank 1 is now plugged into bank 2?
Nice to see the fault Chris.Well I'm not doing anything in this weather, but picked up the old turbo. While I'm *cautious* to say 'Fixed' it sat on the ramps at F1 for 30 minutes idling super smooth while they sorted the tracking. Not a blip, hesitation or anything. Pulls like mad. Even being 'cautious' I nearly ran out of road...
And the wastegate bushing is totally gone
