It’s has been over a year since we have introduced the Non – Contacting ETM upgrade. The purpose of this post is to make all of you Do It Yourselfers aware of the potential issues and problems that others like you have come across during their own ETM installation. We hope you find this information helpful.
Replacing your ETM? Some Tips from an ETM Manufacturer
1. ETM Installed backwards – Yes, it is possible to install the unit with a label facing the engine.
Symptoms: Rough idle, engine will not rev up past 2500 RPM.
Corrective action: ETM must be installed with the label facing the radiator.
2. The old ETM gasket not removed and left stuck to the intake manifold.
Symptoms: Irregular idle, misfire on acceleration. Possible MAF and ETM related DTC stored.
Corrective action: Our units are shipped with a new gasket; ensure that the old gasket is removed.
3. Disturbance to the Turbo Pressure Sensor (One of the two or three sensors located on the intake pipe).

I did this today on my 2000 S70. If you are a somewhat inexperienced mechanic as I am, expect this to be difficult. Compared to the other work I’ve done, bleeding brakes, changing spark plugs, It was quite a bit harder. It’s not hard to understand, just hard to do 
Watch the video and then expect these things to be a bit harder than they look…
1. Pushing the intake hose back to let the fan in and out is much harder than it looks in the video.
2. Using a ratchet and wrenches is much harder than using the very cool pneumatic tool.
3. Putting the first bolt in while installing the new ETM is pretty hard.
4. Getting the intake hose back on the throttle is hard.
5. The video doesn’t show loosening the starter bracket to free the trapped electrical connector. You have to remove the single bolt facing you, but you only loosen the two nuts on the side of the bracket so that it moves enough to get the wire out from under it. If you are lucky you might not need to do this but I did.
6. If you have longer arms (I’m 6’2″ with proportional arms) you will likely find it hard to reach into the bay and under the manifold and then operate tools while holding parts.
Now the good…
The new XeMODeX is great. Previously I experienced weird surging/hesitation whenever I drove the car particularly when cruising at 40-50 mph. After test driving a few miles I found all that is completely gone. Throttle is smooth and controlled at all speeds under all conditions. This car is steadily becoming fun to drive.
XeMODeX has eliminated one more thing you “must” see a dealer for, programming the ETM. Now if only they could find a way to eliminate the dealers’ lock on the key/remote market (there’s a bad pun in there somewhere) I would officially declare them gods of the Volvo home mechanics.

ÙProblem with electronic throttle module.
I check my number and it is 8844435—65CFM9 . Where can I find one, because I check on net and did not find, they only have the 8844347 and I was wondering if it would replace the defective one
Xemodex never sent my ETM out on time, they forgot about it for THREE MONTHS!! They tried blaming it on UPS but there dates never matched up so I knew they were lying, I got my refund and choose to not argue with such unprofessional people.
I’ve read several recommended install instructions, and unfortunately followed the one that says to take out the fan and leave in the intake manifold. In this method one must become a blind contortionist and have the patience of Job. Yesterday I took the ETM out (scrapping car due to transmission failure and horrible engine rebuild by Craigslist idiot). Taking the intake manifold off was FAR easier method. Period. The fuel rail comes off in less than a minute and with u-joint swivel socket, all bolts for intake were out in less than 5 minutes. I strongly suggest making detailed drawing of vacuum lines. I’ve told myself, “Oh I will remember where this goes…” a few times but a couple hours later…”Doh!”
