BMW Diagnostics - A better way to Find Manifold Leaks

If you have misfires when you start your engine in cold weather - the cause is usually vacuum leaks around the inlet manifold. This could be the manifold gaskets, missing blanking plugs, a torn PCV valve or a damaged inlet tract.
Finding vacuum leaks is usually confirmed by squirting brake cleaner/propane/anything to hand at the engine and this method is difficult to perform without losing your eyebrows. Alternatively a smoke machine can be used but this is often beyond the capabilities of the average DIY'er. I show how these can be found on a BMW M62 engine using very cheap BMW Diagnostics that can be bought from many places for just a few quid.
OBDII to 19-pin adaptor: amzn.to/33CFRWN
INPA: amzn.to/33D2NoT
This routine using INPA diagnostics shows you how to find them using the adaptation values. We also explain how the ECU tries to compensate for these laks - and when it fails why it stores the 'adaptations at limits' error code.

Although this routine is shown on the BMW M62 V8 engine, the method is just as useful on all BMW engines in conjunction with INPA diagnostics
