Hello everyone in the forum, after now one year without quirks the fault devil hit again. At times the ABS and TC lamps go on, the speedometer falls off and it no longer works ABS. Sometimes (but really only sometimes..) the steering also does not have the full servo support. My appointment at the FOH was then also not very pleasant. Tech2 could not reach the ABS control unit????!!!!!!! So you wanted to change the control unit directly… approx. 1200,-€. And now to my question e. Who knows the problem and is an exchange really necessary??? Would be really grateful for every tip that it could be… Oh yes. Something else about my treasure… it is a 98 year of construction and equipped with an ABS 5.3… Greeting to all…
