I thought i would start a new thread to see if anyone has cured this problem with the ABS reluctance rings. My 7g gearbox was serviced and software updated a few weeks ago so its not that. When driving around town, if i take my foot off to coast and slow down, i get a light braking effect when it down-shifts at 30mph then 20mph then 10mph, the lower the gear the more obvious it is. I took it to G-services in Coventry today, he is the indy who did my gearbox service. He connected the diagnostics and he found no errors on the gearbox. He checked another control module and said there was dodgy reading from the rear wheel sensors, he said the abs rings need replaced and he thinks that is what is causing my problem. So has anyone else had this problem and found the ABS rings were to blame, i know MB want to sell you a full drive shaft but aftermarket ABS rings can be fitted. I was quoted £220 for both sides. I have also read on other posts, people getting the gearbox software reset and software updates and it did not cure the problem. Is this the answer?
