Indeed! Yes that's the end of the trouble free miles, loss of power this afternoon on motorway while on boost. Everything all pointed to a loose or broken boost hose, or a vacuum issue maybe.
Came to a halt half on a live lane on the motorway, no hard shoulder in sight. Car starts, but dies almost immediately, using throttle makes it die sooner.
Thankfully I've now had the car recovered and it is back home with me and I will start trying to figure it out tomorrow with a clear head and not bloody freezing on a motorway.
So, at the side of the road, I spotted a vac line had popped off, from the rubber t-piece, opposite the blue/black valve, which heads to the fuel damper. Reconnected that and it made no difference. The hose from the brake booster to manifold looks all good, as does the one to the ICV, certainly the connection to the manifold anyway, couldn't see ICV end. The hard boost pipes look fine and connected at both ends. The j-boot looks secure onto the turbo, as do all the fittings around the MAF and airbox. Nothing obvious at all.
Now, as this happened under high boost, I am focusing on air pipes and hoses. Is there anything under the car you can't see from above, that could cause this? Pipes onto the wastegate? MBC lines looked fine up top, obviously haven't been underneath the car yet.
The elephant in the room is the wiring to the MAF and SciVision module. I've had issues with this before, and it is certainly reminiscent of a previous fault, so I will investigate this. It's just the fact it happened under high boost that immediately thoughts were on boost pipes/air leaks. I did have a wiggle of the wires on the MAF/SciVision at the side of the road, didn't change anything.
So I suppose I need to check that wiring. But also where else should I check for a boost related blow-off? Could the j-boot have split and cause this? Answers on a post card please?
I hate cars.
