Pictures of EGR valve after 33,500 miles

I had the emission recall performed today on our 2010 X5 diesel. I asked the technician to take a few pictures of the EGR valve as I've been reading about the soot build-up in the old style valve and was interested to see how much was in mine after 33,500 mostly highway miles. I thought you might be interested as well so here are the pictures:

That doesn't look so bad, Finn...you should have seen my TDI's EGR valve before I cleaned it...

Thanks for posting those pics.

Big benefit of ULSD

Dna Diesel, does the EGR valve need to be cleaned on a regular basis?

Not now, finnbmw. ULSD has significantly reduced soot and I have also adjusted my TDI's EGR duty cycle, particularly since I travel a lot on highway, and NOx production is greatly reduced at moderate-speed part throttle travel. The picture on the right was at about 100,000km when I cleaned the valve and the intake -- VWs (ALH code TDIs 99.5-2003) were well known for gunked up EGR valves). I have about 220,000km on the Jetta and the EGR and intake are almost as clean now as when I cleaned them back at 100,000.

I haven't heard much of E90 D's getting too dirty...the E70s (X5) have a different EGR set-up that I hear has had issues in the past.

what a pain in the a$$ the EGR systems can be..i have no experience with car egr's but i disabled them in my Volvo semi truck and what a beautiful difference it makes! i am thinking about getting a diesel powered vehicle and one of the first things i will do to it disable the EGR! We are not gona talk about the legality here ))..

Anyone borescope their intake to visually check the carbon buildup?

Amigos this what I wrote in the other forum:

Amigos I can attest to this supposedly carbon build up this last saturday as I was going to the 1/2 mile race I had the ENGINE light come up and man i almost SHEIT on myself. I called my mechanic as he was going to race my car for me since I have a broken hand. He told that that occurs also with the JBD on some of his clients. and informed me not to worry I stopped turn car off and back on and it was GONE!! OK I deided later to press on it and GUESS WHAT? Not only the ENGINE light come but also the damn ESE light F'me now Im pissed and scared. I stopped and turned off and back on AGAIN! and the engine light gone but not the SES.

The car was running quite VAGUELY but I realized the the day before I had put on 3 ounces of Amsoil DIESEL injector cleaner and 3ounces of AMSOIL CETANE Booster, I guess all the SOOT was coming off since it had been a month since I had stopped using DIESEL Injector Cleaner. Anyway, my friend drove the 1/2 mile race and he told he clocked 150 mph at the end of the track but forgot to clock at the 1/2 marker(he did it twice) he was VERY IMpressed with the DIESEL, he had had many gassers during his youth and was ALL smiles with the DIESEL. My car clocked the first time 120 mph which I found very disturbing since I had a better program come to find out the systme was not calibrated weel and many competirors were complaining.

Anyway, once I took the car and drove to my uncles house I noticed the car was eager and loose, i looked at my girlfriend and told her "Hey something is wrong with the car, she REPLIED by saying The car is responding better!!" I drove the car to the 1/2 mile race went to my uncles ate and got drunk partied at nite, next day drove to the other extreme of the island and went to see my friends game and drank and ate an came home and looked at the tnak and guess what? 1/2 tank on 243 miles, PRICELES!!!! Now my girlfriend wants a DIESEL!!!

P.S. The SES light went off the next day at my uncles.__________________
