Did this video help you?

Antti Suvanto: No offence, but it´s a big piece of junk made by Magneti Marelli, italy!:D Thanks, great video, now my ride idles smooth!

Viaamtrak: I am getting the "Reduced engine performance" light on the dash of my XC90 T-5 2004 2.5. It drops down to about 10mph, then goes away in about ten minutes or so. Any ideas? Where do I plug in the OBD2?

andyb brown: Thanks, is it possible to reuse the gasket?

Lefteris Mouratidis: sooner or later you WILL need to replace the ETM if its the ETM from magneti marelli. Cleaning will only work for you to a certain point.

Shane Glidewell: Super thankful that folks like you take the time to do a how-to like this. Epic job. 

Christopher Watson: Hello~ Im using my sons site but have used your informative tutorial to clean emt 2x in the past..but im trying to replace due to ongoing surging and insight of recall that unfortunetly doesn't include me. I have throttle housing out as I learned from you in the past, but the electrical wire is leaving me confused and extremely frustrated as I really don't want to incur the expense of having the dealership to replace...do you have any helpful informative assistance that you might share??? Please single mother of three boys trying to save money and learn how to fix and repair on my own :)

Jorge duarte: Hey Chris have you had the pvc replacement done in your s80 if by chance you have, did you take it to a dealer or did it yourself? If you took it to dealer what was the cost? 

Elizabeth Koppes: I had a Low engine pressure warning the other day I brought XC70 -04 to garage they say to replace the trottle body part $ 650! Should I just clean it or is my garage trying to clean me out!

lcg5000: This was very helpful. I appreciate you making a video on this. Sometimes it's really hard to find info on this volvo. Love the car but sometimes electronics just over complicate things and make parts and labor ridiculously expensive

Steve Berg: took my 04 Volvo in today. They recommended $1050 replacement. I sent this link with instructions to clean. My cross country only has 92k. Thanks! 

JOHN CHANDA: THANKS KRIS

andyb brown: I have a V70 and I trace the wire from the TB to the connector which is wound behind starter bracket, so an additional 30cm of wire, but can then remove the whole TB module from vehicle without removing the item you mention at 3:13 

john adams: Thank you for the video. Just finished cleaning the ETM. I just wish you included the rigid hose removal not the easiest item to remove. Done on a 1999 S80 Volvo.

Rob Jenk: Nice vid... Thanks

Steven Fillmore: this is when ford owned VOLVO. I have a 960, swedish build only minor age issues lol

Ebraheem Tatour: VOLVO S80 ETM

Lynn Waters: I realize this video is a couple years old, but can I do this same process to my 2006 XC90?

Michael Collins: I have a 2001 Volvo s-40, 1.9 turbo. My vehicle was experiencing surges ,rough idle. I took it to the dealership and had the coils replaced (ignition colis). The dealership said I needed to replace the IAC hose ,.what that and where is it located?also needs a rest valve, tstat. how do I replace the IACX hose and the reset valve?

Lydia Rodriguez: any idea on how to change the starter in a 2001 volvo s80

pelletiertimothy: This was a breeze to do on my 99 V70. Thanks!

El Salvador: thanks !

Lindstrom18: very helpfull

guitartricky: Thanks man! I did replace the crank position senor but what bracket are you referring to?

1959D356: While your at replacing the throttle body, don't forget to replace the transmission and ABS control unit also.

rudyba: Thank you very much. I have a 2001 V70 and non turbo and have the problem thay was some times very difiult to start. I called my mechanic and he conected the scanner witch red the failure at the ETM. The mechanic told me that it had to be changed for a new one and I red about warranties for Volvo for 200k Milles or 10 years. I live in Guatemala and Volvo in Guatemala does not cover that Warranty. By doing this it started inmidiatly many times without problem, I hope it satys like this. Thank's..

David Redmon: Xemodex..actually rebuilds the one you own so no reprogramming needed

guitartricky: Thanks! The Vai guitar was kinda of an immature purchase when I was younger and going through my "Vai" phase.;) At least back then they were half the price they are now!

Kris Kasprzak: The car is a 2.9, no the turbo version.

mysqueeker: and its so typical. it just shows how wasteful our society is. volvo recommends replacement when all it needs is just a simple cleaning.

Kris Kasprzak: @TybaltC yep you may be right, but I hate my volvo dealership. My old ETM was recalled, but Volvo in their infinite wisdom, basically replaced it with the same crappy failure prone unit.

prelude1983: Hey Kris. I have a problem with my 06 Volvo C70 t5. In the winter it`s very hard to start it. Maybe on the second or third attempt it will go. And when it first start a message willl pop up in the display "motoreffect reduced". This message will stand there for about 5 minutes. Can it be a ETM issue you think? Or maybe the air mass metter or landasonde?

Kris Kasprzak: I don't think the tach jumping before starting is related to the ETM--mine never did as you describe.

jerry pineda: Hi timetotravel, I got 99' S80 that i believe has the same problem like this. I called a dealership here in Vancouver and told me that its out of warranty already. The ETM software update has been done in 2006. Now im pretty much on my own. ( i bought it in 2010 BTW). Are the 4 nuts and bolts underneath hard to take out. Im sorry for my question but i really appreciate if you will break it down step by step. Thanks

TybaltC: My mechanic had me replace my gas pedal which did nothing to fix this issue. I told him about cleaning the ETM and he did. After about five minutes of driving, the car looses acceleration on the road, does not go above 1,800 RPM's or 5 MPH. Anyone know what else it could be?

jprice3331: Yeah thats what i thought. It was a bit harder to do than on the 2.9 but this video does apply to the 2.8 t6. thanks for the guide.This did fix all idle problems i was having.

Mike Gambino: I hope this works on my S70... Lets give it a whirl!!! Got to get that 'gook' off .. (hahah)

TBguitar: I did just as you said, and will test the results later *** 2001/S60

gonzalogagliardi: what about a v70

Deadgurl212: I have a Volvo v70 and it does the same thing nonstop. Also the power stearing jerks around alot when steep on or off the gas what could cause that ?

Kris Kasprzak: @zaidusa With the key in the igntion, hold down the trip reset button. While holding the button down, turn the key to position 1 for 2 sec and the to position 2 untill the service light flashes 3 times. It's tricky and I always have to do this a few times to get it reset.

Kris Kasprzak: de nada!

Aarontown: Wanted to just say thank you. I took out my ETM today and cleaned the holy hell out of it. It was about 100x worse than in this video. I was looking all over for a fix for my idling/surging issues -- luckily stumbled across this video. My Volvo is at 155k miles, and this has never been cleaned. After I reassembled it I drove it around for awhile and it ran like a champ. I thought I would have to take it to the dealership but once I saw this video I knew i had to try it. Thank you so much!

Jason B: Ahhh hmmm "some people" just have to do the "hard way".... In my 2001 Volvo S80 I just took the top half the of the intake manifold and got easy access to the throttle plate. I cleaned it with a wire brush and "throttle body" cleaner and also cleaned out the oily and dirty intake manifold too. I did mine about a year ago still runs great with 132000 miles on it!

Kris Kasprzak: Fine question. In another reply the person didn't replace the gasket and indicated that car ran bad. I don't know if these can be easily bought. I' personally would make one before i used silicone. Just be carefull and take your time--best avoid the issue in general :)

Kris Kasprzak: The 4 bolts are not nearly as hard to get to as it looks. Once you remove the air intake tube they are easy to get to--just follow the video. Note this cleaning is only a temp fix, the real issue is bad electronics in the unit. I'll not replace mine since a replacement unit is worth more than the car.

AlertDuck: Thank you for the video - did this on my 2002 S60 2.0T last weekend and the car now runs like an absolute dream. Such an easy fix been replacing MAF vacume hoses etc for the last year or so with no sucess. It was full of crud and sticky stuff all gone now and works lovely.

guitartricky: Thanks Kris! That helps me narrow it down. Upon more research it seems the tach jump could be due to a failing crank position sensor.

MrTruls75: @timetotravel hello and thanks for this one... my car have been doing this for four weeks now.was going to buy a new one,but here in norway this cost 2000 $,,then i found this video today, tryed it,and now the car runs 100% :-) so again..Thanks.

Rebel: Jees I feel like an idiot. I had this issue for a year, going from mechanic to mechanic. Two days ago I got to dealership to clean ETM and this morning my car got a heart attack. Engine light is flashing, car shakes valiantly, smell of burning. Had I googled it earlier I would have probably save myself $1500. Moral, make sure to check out forums before going to the shop. peace.

AubraneeMusic: Update: my car has been in the shop for a month. The mechanic checked everything including the maf sensor and accelerator pedal sensor but the car still did the same thing. So it had to be the throttle body. Ordered a replacement one from Xemodex on 1/28 got here 1/29 and picked my car up from the shop same day they put it on. Xemodex is such a lifesaver! I was car sick without my baby and this is the first problem I ever had with my car. I love my s80 and thanks Xemodex!
