Hi all, newbe here so apologies if this has been asked before.

Im going to replace my DPF pressure sensor on my 2011 Astra J 2.0cdti A20DTH engine.
Does the new sensor need to be learned in by the car or is it a straight swap?
Whats the best sensor to get, ie Bosch? or genuine GM etc. Anyone got link they can reply with?

P.S Is AutoVaux recommended for parts?

Cheers guys

Yes the new sensor needs to learned.

As for parts I would advise genuine. Yes Autovaux is recommend for parts but always check with your local dealer as sometimes they do come in cheaper.
