Egr - P0405

[crager34]

I had some work done about a year ago and asked the mechanic to go ahead and clean the EGR valve. Not actually sure if he did it, cause the code cam back today. So, when I can I will do the work myself. Also, Autozone said they have the valve for $150, so I may just replace the thing.

With the engine cold, start the car and check for exhause leaks under the valve. you can hear them, or feel it with your fingers before the valve gets too hot.

It may be just the EGR gasket, or the 22mm nut loose under the EGR mounting block.

i had the same code and thought it was the egr also so i cleaned it out and reset the check enging light, but after 300 miles of driving it came back on. Now here is a question after another 1000 miles of driving it went back off. if it is a egr problem would the check engine light go off and on and off again?

Did it go off then came back on? CEL codes clear themselves (after 25 starts, if memory serves).

I get the same code about every other month. (low flow EGR Valve)
Yes, it does reset itself.
I usually help it along by driving a day with the tranny in "drive 2" to let the RPM's get higher.
Someday I'll get around to cleaning it.

On a recent road trip, I had both the engine light and the tranny light come on at the same time, with the tranny light blinking!!! Hard to ignor.
Scared the crap out of me, I couldn't find anything wrong. No funny noises, nothing under the hood.
Turned out, I just needed to top off the tranny oil.

Well guys my toy's engine light is on,i don't for sure what it is,but according to the check engine diagnostic perfomed at autozone the source of the issue is located at somewhere on the emision system or simply the gas cap that deffinetly needs to being replaced,the diesel knocking noise could be probally the EGR valve or worst the lifters according to my mech.
Thankfully i bought the mounster with two years warranty so my guess they'll take care of it

I'll have the code posted tomorrow so you guys might have the answer.

P1402 came up as EGR valve too.
I was going to take mine off, install a new gasket
and see if that fixes it.
BTW, where is the EGR valve on our Vxs ?

also, autozone quote me $119 for one just today
for a new one with a 2 yr warranty.

For the blinking trans light;I got your very same problem. How I fixed? Check the connection or the coolant sensor itself. Really, not a joke. That was my problem, it even get the idle speed very high. This car has so many co-related sensors that you never know which one its the faulty one. As you know almost four sensors controls the TOD; TPS, ABS,etc. Even the odometer is electrical.

you did knock on wood after you said that or in my case my head

Mine came on once going up a trail to go shooting with Bart. I pulled it off and cleaned some carbon buildup off with a piece of wire and made sure the valve moved freely. No problems ever again.

Hi guys, if there any instructions posted to get this EGR valve and the base cleaned? Thanks for any tip.
