my first cry for help

j hitchcock · 24th February 2022, 14:32

hello, i've just bought a mk 2 saloon diesel thats done 70,000mls.
It,st got many faults that I,m working on.
The strangest one is a howling noise when I,m stationery and revving
the engine between idle and 1500-2000 revs.
I,ve checked turbo hoses and air filter box ( there was damage to the box
where it seals, and i,ve corrected this ??? ) any ideas

One of the more knowledgeable folk will be along soon, but I would have a look at the exhaust? Could be you can hear the turbo spooling up via a split in the flexi??

j hitchcock · 24th February 2022, 15:07

Is the flexi the one right by the turbo, thanks

Could it be the fuel line resonance?

Is the air con on? If so switch it off (econ Button) and see if the noise disappears.

As suggested earlier, could well be the exhaust flexi.
