Egr - P0405

[zadam123]

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.

SWEET! Dub art!!!!

My advice: if you can afford it, buy a new one. I tried cleaning mine (7 years old) a couple nights ago for like the 5th time and it is now beyond cleaning. And it has the most god forsaken sulfurous smell to it. That doesn't reassure me at all.

My poor VX is gonna be sitting on the side lines for a while. I have had to throw so much money around lately, no thanks to things in my home all dropping dead one after another, that I am low on the purse. With the economy spook, I need to keep every penny available for any other emergencies in case they arise (and they always do with my luck). Complete new heating and A/C furnaces should NEVER cost $8k.... that is all I have to say about that.

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.
