Technical characteristics
The mechanism of blocking of differential
If the previous model Audi 80 has been still supplied by mechanical blocking of a back axis in А4 blocking is carried out by system EDS. Its advantage consists that blocking operates also on forward wheels, but there is a lack which consists that the effect of blocking is reached only at the expense of braking of a turned wheel that under certain conditions operation is less effective, than at mechanical blocking.
System EDS is closely connected with antiblocking system, therefore the technical information about EDS read in section ABS and EDS.
