Had the Inlet manifold off my dads Porsche cayenne ( basically toaureg ) 4.5 v8 twin turbo.
Now when on idle in park or neutral it's hunts between 1-1.2k ,
But soon as you put it in gear it will idle at 800-900 as normal . Have checked with brake cleaner for leaks but can't find any leaks.
Just weird how it only happens on n or p .
Anyone know any info ? No fault codes yet but not been down the road ....
