| U0401-68 and U0416-68 goes away if suspension is higher |
|
Strange problem. My D4 (2.7, MY 2009) keeps getting communication errors and the engine power is limited.
IID reports:
U0401-68 (A8) Invalid Data received from engine control module/powertrain control module - Algorithm based failure
U0416-68 (26) Invalid data received from dynamics control module - Alogrithm based failure.
First idea: bad battery - replaced (new Exide AGM), but the error remains.
Then I changed the height of the suspension with the IID and raised it by about 2cm at the front and about 3cm at the rear because I had to pull a tandem trailer. What!? The errors don't come back when the chassis is higher. How can that be? The height sensors on the left and right at the rear were replaced last year.
I'm a bit confused here.
