BMW E39 ABS Wheel Speed Sensor BA71020, 1050mm Cable

For E39 5 Series (1997-2004) - including Touring - when the ABS light flickers, traction control cuts in for no reason, or fault codes like 5E20 / 5E21 appear: this is the sensor you need.

• Exact fit for all E39 chassis - saloon, Touring, M5 - regardless of engine (M52, M54, M62)
• 1050mm cable length matches OEM routing; no shortening, no adapters, no guesswork
• BA71020 part number confirmed - not a generic 'E39-compatible' rebox
• Covers searches for: E39 ABS sensor, BMW 5 Series wheel speed sensor, ABS pulse sensor E39, anti-lock brake sensor 520i/525i/528i/530i/M5, E39 estate ABS sensor
• Not a 'stage 1' or 'track day' part - it’s a precise functional replacement. Because race car doesn’t mean ignoring the basics.
