Used Mercedes-Benz 190E Glow Plugs

No – the 190E is a petrol-engined car; the 'E' in the W201 range stands for Einspritzung (fuel injection), and petrol engines use spark plugs, not glow plugs. Glow plugs are a diesel-only component used to pre-heat the combustion chamber, and no variant of the 190E was ever sold with a diesel engine. If you need ignition parts for your 190E, you are almost certainly looking for spark plugs instead. Search for spark plugs matched to your engine code (for example M102 or M103) for the correct fitment.

Yes, almost certainly – the Mercedes-Benz 190E (W201, produced 1982–1993) was exclusively petrol-powered, so glow plugs simply were not fitted to any version of this car. A breaker quoting glow plugs for a 190E has likely misread the request or confused it with a diesel model such as the 190D, which does use glow plugs. Double-check you have the right part name and, if you need pre-heating components, clarify whether your vehicle is actually a 190D rather than a 190E.

The 190D (also W201 bodyshell, sold alongside the 190E) used diesel engines and is fitted with glow plugs; the 190E used petrol engines and has spark plugs instead. The two cars share the same W201 platform and body, so they can look identical from the outside, which is a common source of confusion when ordering ignition-related parts. If you are unsure which variant you have, check your V5C logbook or run a VIN check – the fuel type and engine code will confirm it immediately.

No – every trim and performance variant of the 190E, including the high-performance 2.3-16 and 2.5-16 Cosworth models, used high-revving petrol engines and therefore spark plugs, not glow plugs. Trim level makes no difference here because the absence of glow plugs is determined entirely by fuel type, and all 190E variants were petrol. If you own one of these sporting variants and need ignition components, search for spark plugs specific to the M102 Evolution or M104-based engine code shown on your V5C.

Year makes no difference in this case because glow plugs were never fitted to any year of the 190E across the entire W201 production run from 1982 to 1993, including both pre-facelift and post-facelift (1988 onwards) cars. The part you need will depend on your engine code – for spark plugs on a petrol 190E, that code (found on your V5C or a VIN check) is the most important detail to supply to a breaker. If you genuinely believe your car has a diesel engine, verify the fuel type on your V5C before placing any parts request.
