That's not true Happy. The M54 is a silky smooth engine. But getting it there... well yeah, you hit the headliners. DISA, MAF, vac lines (and gaskets, intake, boots, VC, etc), o2 sensors, VANOS, coils and plugs. I haven't seen many fueling issues with the m54 so I skip injectors and FPR unless something indicates an issue there.

I don't mess around with the above. When I buy an M54 with > 120,000 miles all of those things get done. Only way to own a smooth M54 at the age they are currently. I just did the same with our N52... people have the same complaints about those engines.

Sometimes you just have to bite the bullet.

EDIT: BTW, I am excluding yours as it is a special case scenario, not many like your M54 running around out there. You might have to live with a slightly less than smooth M54. But it makes up for it with smiles and power I'm sure.

With the manual, there is a dead spot from a dead stop even with every repair mentioned. It’s less pronounced when everything is running 100%. The supercharger kind of had an affect on it, but only slightly. It’s definitely not as noticeable though when the M54 has had a total refresh. I can use the clutch to completely avoid it. But, as well I can hit that dead spot like clockwork if I want.

Never had dead spot on either of our M54. I have one on N55 for the first minute on a cold start.

I wonder if the E53 has a clutch delay valve like the E39 manuals did?

Yep, E53 does come with CDV. It was terrible when mine was due for maintenance. Cam, knock, MAF, DISA, coils, vacuum leaks, etc. combined with the CDV was a pretty lack luster experience, especially with only 230 hp. When looking at the live data while operating, nothing shows when the hesitation or dead spot as I like to call it takes place.

The fashion in which my E53 sits currently, the dead spot is nonexistent. I’d have to go hunting for it to find it. It requires letting the clutch out at maybe those most 1100 rpm, having drop down to say 950 rpm, and then once the clutch grabs fully, lay into the pedal a bit, and usually it will hiccup. LoL..

Before the massive tune up though, it would hiccup letting the clutch go at 1300-1500 rpm. I had to learn how to get into the throttle in a manner that wouldn’t cause the hesitation.

Word of advice to at least M54 owners, stay on the maintenance, and the hesitation should cease.

There is a lifespan, but it can be pretty long. My 2001 3.0i at 203k miles is still on its original Bremi coils, with no problems there. I'm not planning to replace pre-emptively, but will not be surprised if they start to fail any time now.

My M54 with the AT is really smooth running and especially when starting out from a stop.

Wow your Bremi’s held up for the long run! Mine were toast. I definitely had the defective part #’s. Plus when tested, failed the threshold.

No need to replace if there are no misfires.

One thing I forgot to ask the OP. At what rpm is the hesitation happening?

about 30 miles driven, coils appear to be the issue. took all apart and cleaned with electrical contact cleaner. No more issues and running smoother. Probably a good idea to clean all coils every 100k miles before replacing.
