===1987–2009: Acrimony, CD reissues, Dinger's death===
Dinger and Rother did not work together during the 1990s. Indeed, there was some degree of bitterness existed between them, not least because Dinger had released a couple of old substandard Neu! recordings on the Japanese [[Captain Trip Records|Captain Trip]] label without Rother's knowledge or consent.  In late 1995, this label released the previously mentioned ''Neu! 4'' recordings from the 1985–1986 sessions.  It also released ''[[Neu! '72 Live in Düsseldorf]]'' (recorded on 6 May 1972), which comprised poorly recorded rehearsals for some abortive live shows, but notable for the inclusion of Eberhard Kranemann, who had briefly been in Kraftwerk with Dinger.

A 1999 tribute album, entitled ''A Homage to Neu!'' ([[Cleopatra Records]]), features covers from artists including the [[Legendary Pink Dots]], [[Download (band)|Download]], [[Autechre]], [[Dead Voices on Air]], [[Khan (band)|Khan]], [[System 7 (Band)|System 7]], and [[James Plotkin]], as well as an original track from Rother entitled "Neutronics 98 (A Tribute to Conny Plank)". Plank had died in 1987.

For many years the acrimony and legal wrangling between Rother and Dinger prevented their reaching agreement over licensing arrangements to make Neu!'s music available on CD. In the ensuing vacuum, illegal and inferior-quality bootleg CDs ([[Audio mastering|mastered]] from old vinyl records) were distributed by an outfit called Germanofon.

This situation was finally resolved in 2001, when Rother and Dinger put aside their differences and entered a studio to transfer the three Neu! albums to CD, from the original master tapes (reportedly mastering each album three times). These were produced and released by [[Grönland Records]] (licensed to the [[Astralwerks]] label in the United States), packaged with stickers featuring rave reviews by notable artists, including Thom Yorke. Following the release of the first three albums, Dinger and Rother tried but failed to agree on a legal release of ''Neu! 4''. Rother called the failure of those negotiations "unfortunate".

Rother has said that he and Dinger had been considering recording a fifth Neu! album, but the idea was aborted after personal disagreements resurfaced between them. Dinger died of heart failure on 21 March 2008. Rother said that he was unaware of Dinger's illness until just before he died.<ref>{{cite web| url = http://www.thequietus.com/2008/05/listening-in-michael-rother-of-harmonia-neu-and-kraftwerk-podcast/| title = Michael Rother podcast interview from the Quietus, conducted at All Tomorrow's Parties, May 2008| access-date = 2008-05-15| url-status = dead| archive-url = https://web.archive.org/web/20080614060913/http://www.thequietus.com/2008/05/listening-in-michael-rother-of-harmonia-neu-and-kraftwerk-podcast/| archive-date = 14 June 2008| df = dmy-all}}</ref>

Rother writes and produces solo albums. Before his death, Dinger was a member of the band [[La! Neu?]] (whose name also irritated Rother), as well as collaborating with Miki Yui and band sub-tle. in a project that is unreleased to this date.<ref>Website of Dinger's last project, Japandorf: www.japandorf.com</ref>
