2 weeks ago my 2005 B5 Passat wagon went into limpmode. P0299. Very little power, terrible acceleration. Turns out there was a cut line beneath the air intake. Pictured below.
I repaired this by cutting the vinyl line clean (losing about 1.5" of line), removing the remainder from the insulated portion, and inserting the newly cut end into the insulated portion. That worked great. Limp mode gone and it ran like a charm.
Until yesterday.
Now it won't even start. Battery is great, so I looked in there and found this just past the air intake.
This is the end of that line.
I'm still learning all this diesel stuff so bear with me... but am I correct in thinking this is a vacuum line that goes to the Turbo, and the N75 Valve? If so, and it's severed, could the leak decrease compression enough to prevent it from starting?
What's the best option to repair this?
Thanks!
Side notes:
Yesterday was our first morning below freezing.
I don't know if this vehicle ever had the glow plug recall done on it.
Recently replaced: Fuel filter (w/ diesel purge), oil (Liqui Moly), air filter, cabin filter & I've been using Diesel Kleen additive about every other fillup.
