Hi All,
For anyone thats interested I have replaced all the parts (2 Pressure Converters and 1 pressure motor and all vacuum hoses with 3mm silicone)... and STILL the lag remains and the turbo noise.
I tried the accelerator pedel reset trick (hold down for 30secs with iginition on, then turn off and then start engine) which also didn't help.
The car reports no errors at all (since I also relaced the faulty heater plug) and all vacuum hoses where tested and the vavles where tested and all moved freely with the exception of the middle vavle, this was a lot stiffer that the large top waste gate and the bottm small waste gate. It moved ok but not not freely and it was harder to move by hand.
The vacuum hose from the supply was tested and is providing vacuum to all the lines which feed the pressure converters.
Not sure what else it can be now apart from a failed small turbo, but would like if I could have this confirmed 100% perform commiting it to. The 530D was easy as I could remove the inlet pipe and test the impeller... and the computer showing no errors at all makes it even more annoying... no smoke to oil in any inlet or charge pipes.
Rev up to 2500rpm sluggish and can hear the turbo noise from inside the car, then over this I get boost and it drives fine.
Open to all and any suggestions...????
PS: Anywhere that provided the 3.5mm hose could not have it shipped to Ireland by Friday, I had ordered 3.5mm black silicone from a suppier in the UK on Tuesday, still hasn't arrived. Hence why I didn't wait as it would be another week for me as I am away working during the week.

My Ride: '06 530i M Sport N52
Hi,
I bought my car in Belfast and paid the VRT on Friday, so not sure how I stand with it, the dealer has no onsite mechanic but did offer to have someone check it for me.
But even if I get a refund I'm out the VRT, and the dealer won't want to take back a now soutern registered vehicle I'd say
It seemed fine to me but now I relalise it had the issue when I bought it, the power seemed fine as I was comparing it to my previous 530D but from reading the forum and a friend drove it who had a 2005 535D I realise it has the small turbo doing nothing, so I'm trying to rule out the quick and cheap solution of hoses and converters before accepting that the turbo might be faulty.
If it turns out to be a faulty turbo I am going to head back to the dealer and see what he can do for me, never should have rushed to pay the VRT :-(
So just need to be sure that 3mm silicone can be used inplace of 3.5mm rubber pipes?
Thanks,
Mark

Check the bottom of the intercooler hose going from and into the manifold if there is a split there it will cause a loss of power... replacing the small vacuum hoses with 3mm hoses should make no difference to performance..
Get it to a decent indi who can do a smoke test and see if you have any leaks..
