All good thanks mate, still lerk around from time to time. Sadly me beemer doesn't amuse me much lol
Lee peeps often make a mistake in finding a boost leak, fixing it and assume all is done in that regard, so do another test.
Also if you have fitted aftermarket side mounts and fitted the original ducts on as well at the front, it has been known when screwing in the fixings to tighten too much and it puntures the alloy enough to cause a leak.
Some don't fit the ducts at all and with some SMIC wonder why they have a boost leak, it's cos in some cases the duct fixing point needs plugging.
Other than that, in the same area, when new hose joiners have been fitted on new SMIC, a leak can occur.
Let us know how you get on,
