Thanks for the replies! Sorry it took a while to update. Fortunately I did get a second opinion and what do you know? No carbon buildup, just the transducer was faulty - so that part needed to be replaced. WAY less than that old $500-something quote I had, ridiculous. That price included an oil change and inspection but still - HECK no. Now the check engine light is back off, all is well, the old subie still keeps going and going and going and going ... Hope other people with the same issue are getting their problems solved! (Of course, now I have to deal with my battery being 100 years old [not really, but...you get the idea] and the fact that it will probably die soon - that and the car occasionally overheats in very hot weather going uphill... but I don't have to deal with that just yet.)

Hello everyone, I'm yet another person with an EGR/p0400 engine issue that I'm trying to find out more about.. disclaimer: I am not a car expert, so bear with me here. Essentially, after well over 200,000 miles, things are getting pretty clogged up. Check engine light recently came on in my 96, 2.2L Legacy wagon. Fortunately, no noticeable driveability problems, pinging or other issues, likely due to the cold. My mileage seems to be slightly worse, but that might be the cold as well..but I do think this is related. I was told the car will pretty much drive fine, FOR NOW, while it's still cold, but that I would see problems as soon as it starts to warm up outside. I was told over time my engine had "carboned up" and that the EGR back transducer (spelling??) is the cause. I would evidently need the back pressure filter and some gaskets replaced as well. This is going to run me nearly $600 (which does include an oil change, but still, YIKES). I'm going to get a second opinion, but has anyone else had a similar issue and had to replace the back transducer? Any thoughts on this? (I apologize if there are several repeats on this topic - I know there are several threads about EGR and P0400 issues, but I have questions about cost of repair that might be slightly different, so I'm posting. If this is repeated too often feel free to delete and I apologize!)
