I had every thing checked 600Km before this occurred. MAF cleaned as well.
MAF cleaned every 5000Km.

It could be a simple case of having the boost accidentally set a over 15psi on the last check.
It had been OK for the last year, and has not occurred again, so just seems an odd thing.
I have red lined before and nothing has happened, no power loss.

So if the systems hits limp mode, which lights are supposed to come on?
I didn’t notice anything in this case.

Anyway back to workshop tomorrow for a recheck and test.

Need them to check a bit of oil on the intercooler intake pipe and some oil marks at the back under the intercooler. Some may be old stains before I dumped the Nissan intercooler.
