Power issues

Paul Coddington said:

Hi A bit of an update on this post. I've changed the turbo, the replacement one was very noisy when it was revved past tickover, so I'm going to put the old one back on, I've given it a check over and it passes all the checks I've read about. So we'll see.
I've done a live data test with my launch device, I'm aware that they don't read the P38 as reliably as the nanocom but it is showing an EGR valve fault. I cleared it but it reappeared after a running the engine again. Anyone successfully tested the EGR valve insitu?? There's some carbon and gunk on the stem. But I'm going to put a vacuum on the unit tomorrow and see what happens unless anyone says otherwise.

I was unaware that the P38 EDC could report an EGR valve fault as there is no feedback to show if it operates. The fault, if there is one, can only be the solenoid that operates the EGR valve using vacuum. As brianp38dse said, pull the rubber pipe from the valve and block it with an M5 screw.

For the egr valve pull the vacuum hose off and plug the pipe with a bolt and you will not have any more problems with it as it will not work anymore and clog the engine with junk

There was no fault displayed on the dashboard. It appeared on the launch diagnostics after running the engine.

That's all disconnected and plugged. I applied a degree of vacuum to the end of the pipe, by way of investigating. The valve hardly moved probably about 2 or 3 millimetres. despite cleaning the thing. Does anyone know what degree of movement there should be? Also are the alternatives to the egr valve a decent idea, or a waste of time?

Why are you worried about the degree of movement of the EGR valve? It's better to block the vacuum pipe so the EGR never opens and thus saves all the exhaust crap from being ingested by the engine. I run both mine like that.
Just make sure that the valve is fully closed.

Pure curiosity, I was wondering if the thing was working.

Providing the egr valve and pipe work are there or appear to be and the engine is working ok it should pass, the operation of the valve is not checked, mine was never fitted with one and passes, its only to help when the engine is cold.
