Fault Code P0299 Turbo Underboost

Post by raid33 » Wed May 13, 2020 4:47 pm

As the title says really! I've had a fault of P0299 come back on my Astra and was wondering if anyone on here has had a similar issue?

Can anyone advise of any things that I could check for before I throw in the towel and chuck it at a garage? (when they open again) Like replacing hoses or anything like that?

It refers to leakage. Pipes or clamps or intercooler...
It needs further ivestigation under bonnet.
