Hey Mercedes diesel owners!
If you're getting check engine lights or issues with your emissions system, the DEF injector might be the problem.

This is a brand new Diesel Emissions Fluid (DEF) injector module from MadHornets.

It fits a range of Mercedes-Benz models that use part number A1644900513.

The manufacturer part number is 0444021024, and it also crosses with A1644900513, 0-444-021-029, 164 490 05 13, and 0 444 021 029.
This is the part that sprays DEF into your exhaust to reduce emissions.

When they fail, you can get all sorts of warnings and even reduced power.
This is a direct replacement, brand new in its packaging.

So, if your Benz is giving you DEF system trouble, swapping out the injector module is a common fix.

Get this MadHornets part and get your emissions system back to working order.
Keep your Mercedes running clean and powerful.
No more warning lights, just smooth driving.
Order your DEF injector today and get back on the road with confidence.

It's the right part for the job.

Your Mercedes will thank you.
Drive on!
