2003 astra 2.0dti no power no turbo - Andrew Moorey (Tune-Up)

Have come across probs with blocked cats. Check first that there is good vacuum at the Turbo wastegate operating bellows. No end of problems in this area with split pipes and failed vac motors bleeding off the vac. Vac control solenoids have been known to fail but I have never had to change one. If you suspect blocked cat loosen off the downpipe flange and give it a try.
