The Dizzy for a GU code motor when fitted to a Syncro can be either from Bosch, Ducellier or Valeo as they appear to have fitted whichever they had in their hand at the time!
More confusingly VW use the same part nr (026 905 205AC) for all 3 of the dizzys from the different manufacturers even though the dizzy caps & rotor arms are different!
Here are the three manufacturers codes for their dizzys and the correct VW part nr for the Dizzy cap & rotor arm.
Dizzy 1) —- Bosch
Dizzy 1A) — Ducellier —- 026 905 206AC — 026 905 207A —- 026 905 225K
Dizzy 1AB) – Bosch
Dizzy 1AC) – Valeo
As well as the above differences the Dizzys also have different vacuum advance units, hall sender units, impulse rotors & internal dust covers.
