Cheap Mercedes-Benz GLE EGR Valve

Yes, but only on diesel variants — the GLE's petrol engines do not use EGR valves, so if you have a petrol GLE (for example a 350e hybrid or a 400/450 petrol), this part does not apply to your vehicle. Diesel GLE models, including those with the OM642 and OM654 engine families, do carry an EGR valve as part of their emissions control system. When searching, make sure you know whether your GLE is diesel before proceeding.

These are two distinct generations — the W166 ran from 2015 to 2019, and the W167 replaced it from 2019 onwards — and they use different diesel engine families, with the W167 moving to the newer OM654 four-cylinder unit as standard alongside the OM656 six-cylinder, whereas the W166 commonly used the older OM642 V6. Because the engines differ between generations, the EGR valves are not the same part and will not interchange. Always confirm the engine code with the breaker alongside your registration to make sure you're quoted the correct unit.

Yes, this is an important boundary — Euro 5 and Euro 6 diesels operate under different emissions calibrations and the EGR systems are designed accordingly, so a valve from the wrong emissions era may not function correctly or could cause issues at MOT. On the GLE, the shift to Euro 6 broadly coincided with the introduction of the W166 generation from 2015, though exact engine and emissions variants changed across the production run. Give the breaker your full registration so they can verify the correct Euro standard and engine code before supplying a part.

No — trim level has no bearing on EGR valve fitment on the GLE; AMG Line, Sport, and any other trim designation are cosmetic and equipment packages that do not change the engine or emissions hardware. What matters is your engine code, fuel type, and emissions standard, all of which are tied to the engine rather than the trim. A breaker will use your registration to confirm the engine details rather than the trim name.

The W166 GLE was closely related to the W166 ML's successor and shares engine families with other Mercedes SUVs of the same era, so there is potential overlap, but you should not assume interchange without checking. Engine codes such as the OM642 were used across multiple Mercedes models, which can work in your favour when sourcing used parts, but small differences in fittings or software calibration can exist. Confirm with the breaker that the donor vehicle's engine code and emissions specification match yours before agreeing to buy.

Before sourcing a used EGR valve, note your exact engine code (found on your V5C or inside the engine bay), the Euro emissions standard of your vehicle, and whether your GLE has the older OM642 V6 or the newer OM654 four-cylinder, as these use entirely different valves. It is also worth having the fault diagnosed properly first, since EGR faults can sometimes stem from a blocked cooler or sensor rather than the valve itself. Give the breaker your registration and engine code directly so they can match the part accurately from their stock.
