Got to agree with this my indi said he has changed so many 2.0D engines that he can change them in under 2 hours now.

You only need to go back one page to find the answer! In a word, yes.

A lot of the follower failures seem to happen not long after an inspection 2 from what I have read, does anybody know what's the causes the the follower to wear away ,poor hardening, incorrect adjustment, lack of inspection to see how badly they are worn before shimming. There must be a maximum shim that can be fitted shortly before failure. Why only a couple seem to wear badly. If it was a bad batch of material then surely all of them would wear out equally. Thoughts?

Maybe because the follower deteriorates so quickly once the case hardening has gone, that you’d need all follower coatings to fail at *exactly* the same time to see equal wear.
But you do hear of only one follower failing sometimes. I don’t know whether this means that just one follower started tapping or only the coating on one follower failed (or both). That would be inconsistent with bad batches, assuming that engines are fitted with followers with contiguous production dates.

Generally bearings on a rotating shaft, or wear points like followers all wear at different rates due to oil flow, temperature and loads due to the shaft 'flexing' at high rotation speeds. I also think you are spot-on with the point about accelerated wear once the hardened surface is breached, once a wear point develops it will always catch. My guess is that as with crank bearings the same followers probably wear first on average engines.

As above. The case hardening on the followers is very thin, once it’s gone, the follower fairly quickly trashes the cam lobe with which it’s paired.
Schrick sell coated OEM followers that should lessen the wear rate.

In other news, she's going back this weekend for some exhaust heat shield welding action, wheel refurbs and dyno run.
In totally unrelated news, our long serving E92 330i is being replaced by a 440i on Thursday. 158k and a decade later she's being replaced.
I will shed a tear.

The new bearings are supposed to have a run-in period of 1k miles or so - not sure I'd want to be putting it on a dyno that soon

My cat heat shield rattles like a pig. I had it welded a few years ago but grounding on an aggressive change in camber at a drive entrance put pay to that. The good news is that welding it cures the problem, the bad news is you’ll dislodge it again at some point!

According to BMW's workshop manual that's not true (and also what I've been told by my shop), no run in period is required for these on replacement. I think most just take it relatively easy for a few hundred miles to be on the safe side, 1k is unnecessary.

By BMW's workshop manual you're referring to TIS/ISTA? I couldn't find any reference to it and unless it specifically says that a run-in period isn't required I wouldn't take it to mean that it isn't.
I know the arguments which say that the break-in is unnecessary, but it is recommended by BMW: under SIB 11 04 04 (rod bearing updates for early E46 M3s) it specifically states that a 1200 mile break-in period is required following the correction work. I have two friends who are experienced BMW techs, both E46 M3 owners and they agree that a break-in should be performed.
That said, I do agree that 1200 miles of break-in is certainly overkill but dyno runs are not a casual engine operation so I definitely wouldn't be doing one too soon after the bearing change!

Definitely run these parts in for a period, its will hurt nothing to do so and give you piece of mind.

^^As above ^^ if it was my car I wouldn’t let it go near a Dyno at this early stage.
I certainly wouldn’t want to be changing the bearing shells twice
