Frequently Asked Questions
Do VADEN parts fit the OPTARE SOLO?
Yes — VADEN manufactures aftermarket parts compatible with the OM904 engine code used across the OPTARE SOLO family; each of the 30+ references in the catalogue is listed with the OEM numbers it fits.
I only have an OEM number — is that enough?
It is. Entering the OEM number into the product search directly lists the matching VADEN reference — this is the most reliable way to select the right part.
Which SOLO engines and generations does VADEN's OM904 range cover?
VADEN's OM904 fitment applies to the original Solo's (1998-2012) standard OM904LA engine and to the Solo SR's Euro V/EEV period (roughly 2008-2014); Euro VI diesel SRs from 2014 onward use a different engine family (OM93x), and battery-electric EV versions have no diesel engine at all.
What VADEN part groups are available for the OPTARE SOLO?
Two main groups: Air Brake Compressors and Engine. Both cover products compatible with the OM904 engine code.
Will a part bought for one generation fit another?
Not always — engine families and sub-components can change between generations, especially across the Euro VI transition. Cross-generation fitment should always be verified by the OEM number.
