So any help would be nice because i dont know where to look so help me please.Any help would be nice. ..

 

please help me

 

Yesterday I was reading your post. I gone to work and I came back. When I was parking the car, the lamda light came on. I searched, and I found that removing the negative cable from battery for 2-3 minutes, willmake disappearthat light. I did it and it worked. Now I will see if it will appear again. Then it means that I have a problem. Have you tried this one?

In the VADIS version that I have I did not find anything regarding cleaning. Here is the exploded image from VADIS

and here a link explaining the solenoids and some tips for cleaning.

Look on the side of the Air box near the engine. There is a valve with 3 hoses going to it.
That is the waste gate control soleniod. Pay close attention to hose location before removing the hoses. You can try to clean it out and see if it helps.
I have a feeling you will need to replace it.

 

ok thank you both very much, i will check on this when i get home from holidays, thats what i thought i had to do was replace the valve,and this clears up what valve im looking at. so thank you very much. Hans_gregor would you let me know if your light comes back on, when i disconect my battery for a few mins the light goes out and then if i let the car idle for a few mins the light comes back on, this is why i had the car scanned and the tech told me that the solenoid was sticking, so i'll check it. but my lamda light doesn't come on untill i let the car idle.

 

Today, after a bumb in the road, the light came on!!! LOL I cleaned that solenoid but the light is still there . It's strange. Beacause first time, the light came on after I put the some gas. I drive a few miles and I had a message that the tank door is open. I stopped to verify. The tank door was closed. I opened and closed, just in case. Got back in the car and the message dissapeard. After that, I went home and the light came on while parking the car. STRANGE CAR!

 

yeah very strange, i cleaned the solenoid and the car is still acting funny. when you first start out the turbo's seem to act funny, like the boost is over boosting and the car wants to take off on its own, in first gear the car will lurch and then lean itself off even when you dont throttle it like you want to take off it just goes. im confused. my lamda light is still out though.

-- tech, do you have any answers for the erratic boost issues that im having?? thanx.

 

Oh and one more thing, if anyone has had this wastegate solenoid changed, i woudl like to know the volvo part # for it. so that if my erratic boost problem is the solenoid i can order one, cause i am a long way from a volvo dealer. thanx

thank you, i will call the dealer tomorrow, i hope that tech has a chance to let me know if he has an answer for my erratic boost or if i just happen to have a bad solenoid. thanx

 

LOL. Today I went to a friend. When I arrivedthe light was on.I lethim to drive it a little bit. When he started the light was off.!!!! I will keep an eye on this!!![sm=jawdrop.gif]

 

stupid light, i think mine comes on if i drive the car harder, i still have a feeling that the solenoid is sticking, just because the turbo still boosts funny. i dont know. still havent called the dealer for a price on the part.

 

Do you mean that your light was not on all the time?

 

wll i mean after o reset the light by dissconnecting the battery, the light comes on after i let the car idle and it comes on sooner if i drive the car harder, i think. i dont know, still havent called the dealer.
