I don't know when this was issued, but I sent my car in on Saturday to have this done:


Turns out there was also a safety recall outstanding on my car:

Recall notice, Oil Pressure Switch

Constant quality controls revealed that on your Astra with Z16XEP engine the upper oil pressure switch might release engine oil onto the heat protection shield of the exhaust manifold, and in the worst case the oil might self ignite. In the interests if vehicle safety we have decided to recall a certain number of Astras to have both oil pressure switches replaced.

I sent an email to vauxhall.customerassistance@gm.com with my reg number and they were able to tell me about recalls that are outstanding on my car. All work was under Warranty, shame there is no recall for the clutch judder
