Hi guys this is my first post. Just picked up my 98 w202 c180 that had the above fault. Really enjoyed the drive home I'd just love to sort the issue. I've been reading on many forums about brake light switch etc. I held my foot on brake while starting but light was constant. Owner said mechanic scanned and said abs module fault. My plan is to clean and check wheel sensors, have a look at the brake switch, try the reset trick and check fuses etc. If I have to change the module and pump as they suggested is there a way to prove its the culprit? BTW drives fine. Cruise control works perfectly and brake lights with as expected with no limp mode or performance issues. If someone has links to threads that are relevant or just some tricks to try I'd appreciate it
