But would the egr valve cause my no communication with any code reader. Also why the pedal test won't work

No noise mate at all. Do you think egr valve could be the problem

Doing my head in mate. Been told today that it could be a ecu fault regarding unable to use diagnostic readers and pedal test.

The van is smoking under acceration and loss of power.

Hi guys new to the group. I have a mk4 astravan 1.7cdti 53 plate. Both the spanner light and engine management lights are both on all the time. The pedal test does not work and I've had 3 different diagnostic readers plugged in. All 3 readers say unable to cumunicate make sure ignition is on. Which it is. I've checked all fuses and there ok. I've got power to the obd port aswell plz help as I don't know where to turn now. Thanks guys any advice most appreciated
