As Wammers says.
Diagnostics just forces the gauges to read either empty, 1/4 full, 1/2 full, 3/4 full and full in order to check accuracy.
In the case of the temp. gauge, it forces it to read Cold, Normal and Hot positions.
It does not calibrate the gauges nor senders..
Yes you do.As per the title really. Changed fuel pump and put over 30Lts of diesel in. Gauge showed only 1/8th of a tank where it should be around a third of a tank.
This is true how are you John?
Hi Tony....Things all over the place mate.
PM "Gemsdad" for details.
All the best.
