W220 Front ABS Sensor for Mercedes-Benz – Ref 2205400117 / 2205400217

This W220 front ABS sensor is a front wheel speed sensor for the Mercedes-Benz W220 and W215 chassis, which the supplier lists under the reference numbers 2205400117 and 2205400217 and describes as suitable for the left or the right side. It is sold as a single sensor. Easy Life Markets offers it to owners of these big Mercedes saloons and coupes who are chasing an ABS, ESP or BAS warning that a scan tool has pinned on a front wheel.

On a car like this, the wheel speed signal is used by far more than the anti-lock brakes. Stability control, traction control and brake assist all read the same four sensors, which is why one failed unit can light several warnings at once and make the car feel as if something serious has gone wrong. Usually it has not. A wheel speed sensor is a small part, and replacing it is a routine repair once you know which corner has failed.

What You Receive

1 x front ABS wheel speed sensor

The supplier describes the contents as "as like the picture" with one item in the pack. No mounting bolt or clip is listed, so keep the original hardware from your car.

Listed Vehicles

The listing title names the Mercedes-Benz W220 and W215 with the S430 and S500. The supplier's attribute list adds these entries:

Mercedes-Benz S500, 1998–2005
Mercedes-Benz CL500, 1998–2005
Mercedes-Benz CL600, 1998–1999 and 2001–2005

Treat those year ranges with some caution. They are the supplier's, they start earlier than these two chassis were sold in some markets, and the supplier states openly that its compatibility list may not be fully accurate. The chassis code and the part number are the reliable guides here.

Left and Right: Read This First

The supplier gives two Mercedes numbers, 2205400117 and 2205400217, and says the one sensor it sells suits either front wheel. On the original parts, two numbers normally mean a separate left and right item, which can differ in lead routing. So before you order, look at the number on the sensor you are replacing, and compare the lead and plug on your car with the photos on this page. If you would like us to check, contact us with your VIN and tell us which side has failed.

Checking Fitment Step by Step

Read the fault memory to find out which wheel is reported.
Take off that wheel and find the number on the old sensor or its lead.
Compare it with 2205400117 and 2205400217.
If the number is worn away, use your VIN in a Mercedes parts catalogue.
Owners of right-hand-drive cars should double-check, as the supplier advises extra care for those versions.

What a Failing Sensor Looks Like From the Driver's Seat

ABS, ESP and BAS messages or lights appearing together
Warnings that show up after a few metres of driving and clear after a restart, then return
Traction control cutting in on a dry, straight road
ABS working at walking pace as you roll to a stop
A stored code for the front left or front right speed signal

The same warnings can come from a weak battery, a faulty brake light switch or a damaged reluctor ring. A proper code read is worth the few minutes it takes.

Installation Notes

Lift the front of the car and support it securely. If your car has air suspension, follow the service manual's jacking procedure.
Remove the wheel and locate the sensor in the steering knuckle.
Unplug the lead and release it from its clips, noting the routing.
Remove the retaining bolt and draw the sensor out. Corroded sensors can be stubborn, so use penetrating oil and patience.
Clean the bore, fit the new sensor and tighten the bolt to the specified torque.
Reconnect the lead, refit the wheel and clear the stored codes.

Use eye protection and gloves. ABS is a safety system, and on a car with air suspension in particular we suggest leaving the job to a qualified mechanic if you are not used to working on it.

A Few Things That Shorten Sensor Life

Heat from hard-worked brakes, road salt and age all attack the sensor and its lead. Wheel bearing work is another common cause: a sensor that is not removed before the hub is pressed apart is easily crushed. When you fit the new one, make sure the lead is clipped in every holder and cannot touch the brake disc or the tyre at full lock. A lead that rubs through will set the same fault again.

Who This Sensor Is For

It is for owners and independent specialists looking after a W220 or W215, and for anyone who has confirmed the Mercedes number on the old part and wants a like-numbered aftermarket replacement.

Common Questions

Is this a genuine Mercedes-Benz part? No. It is an unbranded aftermarket sensor sold under the Mercedes reference numbers 2205400117 and 2205400217.

Do I get two sensors? No. The pack contains one. Order two if you are doing both front wheels.

Can I use it on the rear axle? No. The supplier lists it for the front only.
