 How do you notice an EGR failure and do you now why it failed so early? | ||

Prior to that the chucka-chucka when you turn the engine off becomes lauder, or doesn't happen at all. In the end it will get stuck and then produce a fault code and check engine light illumination. Possibly a limp home mode on the engine. The problem is carbon/soot build up on the valve, the chucka-chucka is a cleaning cycle but it is insufficient. I will change mine soon and see if I can clean it and create my own part-swing system by always having a good one on the shelf. | ||

 So in my case I can see the valve failing. And of course eventually the engine light This is now the third Egr valve from new in 2015. Now just on 106000 odd miles. Car driven daily all that time with good distances etc I did look to try and rejuvenate and old one but I found they are not easy to clean and should really be fully dismantled. That involves cutting some welded joints. I didn’t bother in the end. But if you can clean and re-use I would be keen to see the process 👍 2015 90 XS Santorini Black | ||

| Johan_B Member Since: 20 Sep 2024 Location: Gothenburg Posts: 171      | Seems we have different valves between the 2.4 and 2.2. I haven't seen the component myself but seen reports on here that the 2.4 valve is serviceable. | ||

| Vitesse Member Since: 21 Mar 2014 Location: Sussex Posts: 409      | Yes the 2.4 egr valve is different.  I am unsure if it is more serviceable or not. 2015 90 XS Santorini Black | ||

| jbcollier Member Since: 29 Apr 2024 Location: Edmonton AB Posts: 286      | It is easy to take the 2.4 EGR valve to pieces.  Getting it out in the first place is of equal fun.
 I recommend removal and software delete as the EGR valve creates harmful deposits. | ||
