Used Vauxhall Mokka Glow Plugs

Glow plugs are only found on diesel-engined Mokkas — they are a diesel-specific component used to pre-heat the combustion chamber for cold starts. Petrol versions of the Mokka never had glow plugs, so if you own a petrol Mokka you will not need them. If you have a diesel Mokka, the correct glow plugs are determined by the engine code on your V5, so make sure you have that to hand when requesting quotes from a breaker.

The engine code matters above everything else when sourcing glow plugs — the same plug will not necessarily suit every Mokka diesel. The Mokka A (2012–2016) used 1.6 CDTi and 1.7 CDTi diesel engines with different engine codes, and the Mokka X (facelift, 2016–2019) carried revised versions of these units, each potentially specifying a different plug type or thread specification. Always cross-reference the engine code from your V5 or a VIN check with the breaker rather than relying on year or badge alone.

The Mokka received a significant facelift in 2016, becoming the Mokka X, and engine changes accompanied that update, so you cannot assume glow plugs from a pre-facelift 2014 car will cross over to a 2017 Mokka X. The safest approach is to compare engine codes directly — if both cars share the same engine code the plugs are far more likely to be compatible, but you should still confirm this with the breaker against your registration before buying.

Trim level makes no difference to glow plug fitment — whether your Mokka is in S, SE, Active, Design, Tech Line, or Elite specification, the glow plugs are determined entirely by the engine code, not the badge on the tailgate. You may find cosmetic differences between cars from different trim levels, but the drivetrain components are unaffected by trim. Focus on the engine code from your V5 and let the breaker match from there.

A diesel Mokka typically has one glow plug per cylinder — so a four-cylinder diesel engine will have four glow plugs in total. It is generally recommended to replace the full set at the same time, as plugs age at a similar rate and a used set from a breaker should ideally all come from the same donor vehicle and engine to ensure consistency. Confirm the full set and engine code with your breaker when requesting a quote.

If a donor vehicle from a different Vauxhall model shares the exact same engine code as your Mokka, the glow plugs themselves are very likely to be the same part, since glow plugs follow the engine rather than the body they are fitted to. However, there can be ancillary differences in how components are routed or fitted in a different engine bay, so it is worth confirming compatibility with the breaker against your specific registration before purchasing.
