Hi everyone, 

 

I made a post a while back about egr valve issues with my car. It appeared the problem was a seized egr cooler flap, I freed it up and hoped the problem would not re occur but it has. Does anyone know a way to stop this happening or is the only proper fix new egr valve unit?

 

The vcds readout seems to show a discrepancy between vacuum solenoid activation and actual value which also makes me think that is the issue. Other than this there is no other recurring codes.

One final thing to note is that when I apply the accelerator, very occasionally there is a hesition for about a second then the car accelerates normally. Could that be symptom of the valve itself (not just the flap in the cooler) sticking too?

 

 

By the way my car has the 2.0 tdi cffb engine and is a with 95k miles.

 

 

 

I tried all sorts but ended up biting the bullet and replaced the egr valve/unit.

mine had done about the same milage, I took mine apart afterwards for a look and it was nowhere near as bad as I seen some on YouTube.

It fixed the fault so something must have been wrong.

The effort to take it off, there was no way I was chancing cleaning it and putting it back on to try

This was my thought too, if the egr valve is coming off its getting replaced. It's just I want to be pretty sure first that it's actually the egr and not something else like a leaking vacuum line as it's a lot of time, effort and a fair bit of money to replace.

If you follow the vacuum line from the egr valve it comes to a small solenoid in the engine compartment.

I changed that but didn’t make any difference.

Mine used to fault and go in limp mode with coil light flashing, then be ok for ages.

It then got more and more regular and started putting the engine management light on.
