toledo tdi jumpy kangeroo

[nathal]

my 02 tdi 110, is a bit jumpy.

When driving, i can hear a hiss, and car jumps, its as if it losing pressure
any ides

 

[nathal]

it seems to be that, sometimes when i let my foot of accelerator, i get a hiss, (pressure is released) other times, it doesnt release or releases to early, would this be my diverter valve

Do you mean that as your driving along you loose power and hear a hiss?

 

[nathal]

yes, lets it out is small hisses and lose power, but not limp mode

 

[sssstew]

sounds like a boost leak somewhere then, check all your hoses. Obviously not enough to trigger limp yet.

opened bonnet and switched off car, the n75 valve continues making a low noise, so changed over egr valve with n75. the n75 in new position still makes noise when engine turned off. would this be the n75 knackered

i never heard mine making any noise, so certainly worth replacing. But back to the main topic, now youve swapped it does it kangaroo anymore?

now that i have swopped them, it does kangeroo any more.
