Hi!
I have 97 Audi a4 1.9tdi 110 afn engine which doesn't behave ))
The ecu keeps putting engine in limp mode with "intake manifold pressure indifference". I replaced vacuum lines and checked vacuum valves - no luck.
Recently I did boost leak test. Set my tool to 30 psi. The pressure drops to ~5psi. However if I block egr, the dial shows ~14psi.
My question, is egr should be air tight or air leak into exhaust manifold is ok?
Thanks for any ideas!
