Mercedes Sprinter Glow Plug & Relay Kit – NCV3 2.1L OM651 | 2013–2018

Extended cranking in cold weather, white smoke on cold starts, rough idle until warm, and glow plug fault codes on an OM651 Sprinter signal that the glow plug system needs attention — and the OM651 uses a 4-plug layout with a different relay than the OM642, making engine-specific kit selection essential. This is the complete glow plug and relay kit for NCV3 Sprinters equipped with the 2.1L OM651 4-cylinder diesel engine from 2013–2018, covering all four plugs and the OM651-specific relay.

What's Included

Four Genuine Mercedes-Benz glow plugs (0011598001OE) — one per cylinder — replace the full OM651 4-cylinder glow plug set simultaneously. The OM651 uses four glow plugs, not six, and the plug specification differs from the OM642. The glow plug relay (6519007903 / GSE180) is the Genuine Mercedes-Benz relay for the OM651 system — the "651" prefix confirms it is OM651-specific and not compatible with OM642 relay modules. When the relay fails, it may fail to energize all four plugs simultaneously, causing cold start symptoms that persist even after plug replacement.

Critical: Verify Engine Code Before Ordering

This kit is for the 2.1L OM651 4-cylinder engine only. It is not compatible with OM642 V6 engines, which use 6 plugs and different relay modules. Always verify your engine code (651 on the engine block or via XENTRY) before ordering.
