The first winter, when braking hard, it still turned on from time to time (after restarting the engine, it went through a checking procedure). But, it eventually stopped working.  <\/p>\n\n<!--more-->\n\n<p>The solution came with the purchase of a VAG USB OBD1 Interface (about $130) and plugging into the bus computer. All the systems in it are just this ABS, nothing else seems to be able to be checked.  <\/p>\n\n<p>The indicated problem is a right wheel sensor error. Without this de facto diagnosis, it could take longer to find the cause. For example, a problem with the ABS control panel itself, a problem with the ABS lace, etc.  <\/p>\n\n<figure class=\"wp-block-image size-large has-lightbox\"><img decoding=\"async\" width=\"1160\" height=\"818\" src=\"http:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1160x818.png\" alt=\"\" class=\"wp-image-2492\" title=\"\" srcset=\"https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1160x818.png 1160w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-800x564.png 800w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-120x85.png 120w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-90x63.png 90w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-320x226.png 320w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-560x395.png 560w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image.png 1407w\" sizes=\"(max-width: 1160px) 100vw, 1160px\" \/><\/figure>\n\n<h2 class=\"wp-block-heading\">Repair<\/h2>\n\n<p>The repair is simple, but relatively time-consuming. At least for me it was, but I remind you that I have no experience in mechanics.  <\/p>\n\n<p>The old sensor, due to the fact that it was baked (apparently an affliction of the VAG group of this period and in this topic) immediately treated, was to be thrown away.  <\/p>\n\n<p>Useful tools were:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>screwdriver<\/li>\n\n\n\n<li>chisel, tamp<\/li>\n\n\n\n<li>hammer<\/li>\n\n\n\n<li>Pliers  <\/li>\n\n\n\n<li>round file<\/li>\n\n\n\n<li>sandpaper<\/li>\n\n\n\n<li>sensor (part number 701927807A)<\/li>\n\n\n\n<li>screwdriver, torx wrench<\/li>\n<\/ul>\n\n<p>The repair is to lift the car, and remove the wheel. Then disconnect the sensor wires and try to remove it. Here, of course, it failed, and after several attempts, the sensor wire broke off from its attachment.  <\/p>\n\n<p>Then I tried to ream the sensor itself (from a small drill bit upwards), and after a while (not short at all) to get to the plastic sleeve that encased the sensor, after removing it already went a little more smoothly.  <\/p>\n\n<figure class=\"wp-block-image size-large has-lightbox\"><img decoding=\"async\" width=\"1160\" height=\"874\" src=\"http:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-1160x874.png\" alt=\"PLASTIC ABS SENSOR SLEEVE VW T4\" class=\"wp-image-2493\" title=\"\" srcset=\"https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-1160x874.png 1160w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-320x240.png 320w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-800x602.png 800w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-1536x1157.png 1536w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-300x225.png 300w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-120x90.png 120w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-90x68.png 90w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1-560x422.png 560w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-1.png 1717w\" sizes=\"(max-width: 1160px) 100vw, 1160px\" \/><\/figure>\n\n<p>After removing the bushing, this was not the end of the work, it was still necessary to fight with the elements of the coil that remained in the hole.  <\/p>\n\n<figure class=\"wp-block-image size-large has-lightbox\"><img decoding=\"async\" width=\"1160\" height=\"874\" src=\"http:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-1160x874.png\" alt=\"\" class=\"wp-image-2494\" title=\"\" srcset=\"https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-1160x874.png 1160w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-320x240.png 320w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-800x602.png 800w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-1536x1157.png 1536w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-300x225.png 300w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-120x90.png 120w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-90x68.png 90w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2-560x422.png 560w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-2.png 1717w\" sizes=\"(max-width: 1160px) 100vw, 1160px\" \/><\/figure>\n\n<p>Until I managed to clean the whole thing, so that the ABS system crown was visible.<\/p>\n\n<figure class=\"wp-block-image size-large has-lightbox\"><img decoding=\"async\" width=\"1160\" height=\"874\" src=\"http:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-1160x874.png\" alt=\"\" class=\"wp-image-2495\" title=\"\" srcset=\"https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-1160x874.png 1160w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-320x240.png 320w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-800x602.png 800w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-1536x1157.png 1536w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-300x225.png 300w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-120x90.png 120w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-90x68.png 90w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3-560x422.png 560w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-3.png 1717w\" sizes=\"(max-width: 1160px) 100vw, 1160px\" \/><\/figure>\n\n<p>The next step was to thoroughly clean the hole with a round file until the new ABS sensor entered it without resistance. Here, too, it took a while, but thinking how much time I spent on removal, I preferred to do it thoroughly.  <\/p>\n\n<p>Before inserting the sensor, I additionally greased the hole with copper paste so that the component could be replaced more easily in the future. It seems that if it doesn't help, it certainly won't hurt.  <\/p>\n\n<figure class=\"wp-block-image size-full has-lightbox\"><img decoding=\"async\" width=\"974\" height=\"1293\" src=\"http:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-4.png\" alt=\"\" class=\"wp-image-2496\" title=\"\" srcset=\"https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-4.png 974w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-4-800x1062.png 800w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-4-120x160.png 120w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-4-90x120.png 90w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-4-320x425.png 320w, https:\/\/tuitam.pl\/wp-content\/uploads\/2023\/01\/image-4-560x743.png 560w\" sizes=\"(max-width: 974px) 100vw, 974px\" \/><\/figure>\n\n<p>The end result, the ABS sensor works, the light does not illuminate, the brakes do not lock.
