egr location

[daveg2014]

Hi all struggling to find an answer, is the egr on the front, its a 2005 seat altea 140 TDI

 

[Viking]

Number 6...

Cheers big help everything I had read was talking about at the rear and saying how tricky it was to change. Guess this job has now got a lot easier

 

[Viking]

Why are you changing the EGR?

 

[daveg2014]

Engine management light is on and diag says egr fault inserficient flow

 

[Viking]

What's the fault code please? Usually it's not an EGR fault as such, but the Inlet Manifold Flap sticking, or manifold blockage etc.

 

[daveg2014]

P0401 egr system insufficient flow

 

[Viking]

Well, I'd whip it off and have a look, make sure it's moving okay and not clogged up. As you need to remove the IMF as well to get to the EGR valve I'd also have a close inspection at that first and make sure the flap in that is moving and not sticking open.

The IMF is directly below the EGR, and part of its function is to close completely when turning the car off to stall the engine. The other part of its function is to part close when EGR is needed to slow down the inlet air flow. This causes a vacuum in the EGR system and draws the exhaust gas into the inlet.

Ok I will buy the the part either way and fit it if needed. I'm pretty handy on petrol engines but egr's turbos etc are meaningless to me. The car does seem to run well and return a decent mpg although its a new car to me so not the best person to judge.

 

[daveg2014]

Also IMF?

 

[Viking]

Inlet Manifold Flap, more commonly (and perhaps incorrectly) referred to as throttle valve, number 8 in the pic.

 

[daveg2014]

OK thank you, really appreciate your help

Another vote for checking the IMF, as well as what Viking referred to it some also call it the ASV (Anti Shudder Valve).
I replaced mine on my old PD as it was stuck open (as mentioned, a juddery shutdown is a sign). It can play havoc with errors, unfortunately they are not cheap. I got a Pierburg one from ECP for about £130 at the time which was cheap.

 

[daveg2014]

I have seen people mention that the asv IMF or what ever name you fancy can cause the engine to run for a moment after you turn that car off but I've not had that

 

[skard]

Mine didn't overrun, just felt like it was stalling when I killed the engine.

You can manually check the flap operation by temporarily undoing the inlet hose and have a mate operating the ignition, it should close then open.

I will clean egr valve on my own. I have two parts, magnetic and mehanic. I also have leaking oil from front hole. And this will help me.
