[tim@Oz]

HI

My problem is that the transmission thumps.......the error messages are

[Car: 118i, E87, 02/2005. Australia (RHD)]

1.Selector Position Switch Fault
2. EGS Communication Fault
3. Transmission DATA Connector leaking
4. ECCentric Shaft Fault


Is there a relationship between ECCentric shaft and Transmission(Auto).

What needs to be done to fix this transmission issue.....or

Do I need to fix the VANOS which may be causing the trans problem....is there a relationship between this.

Would be heaps useful to know this and resolve at a resonable cost....

What comes first

Suggestions any ideas on cost of repairs from your experience.
