Believe its the 98 and up turbo where one has to move the air cleaner box. On my 96 turbo I didn't have to disconnet the air box. Took about 15-20 minutes to get the thing out. By the way Victor was great to work with. Its been three months since I had the work done and haven't had any problems.

I can't add much to what's been said except more encouragement. Victor repaired the unit from my 96 850 Turbo last year. Just be patient with the bolts - they are underneath the unit and so you have to do it by feel, not by sight. I consider myself a novice mechanic, so if I can do it, you can do it.

Also, you can drive the car fine but the odometer will not work while the unit is out, so just be aware that any mileage you put on will not be recorded.

Petitcheval, you have almost already answered your own question. Click back on Victor's link and when it comes up, click on 850 and 70 Series Removal Instructions.
Once there, click on Turbo Model and it will take you to an excellent set of pictures and instructions showing you where things are and a step by step removal. You can click on each individual picture and make it larger and print same so you have something meaningfull to reference when you are working in the engine compartment.
A word or caution, the job is not too bad if you take your time and make certain that you fit the E5 socket snugly on each bolt head (there are four).
It is easy to round the head of these soft bolts and then you will be looking at trying to remove the head with a dremel tool and almost guaranteed damage to the abs control unit case.
Please let me know if I can help further. Good Luck, Fred.

It helps to have small hands/arms.

TIP: Place a rag under the area of the ABS module, you don't want to loose the bolts or E5 tool under there. I dropped the tool under there, still can't find it. Also, after you get the unit back use a plastic tie to secure the connector to the ABS module. There is a TBS from volvo on how to secure that connector which tends to become loose from years of vibration.

I wrote about the TBS and I even posted a picture with the plastic tie around the module in volvospeed.com. You can do a search to read about it.

Bonjour littlehorse,
The unit is just under the power brake cylinder. Look under the hood, just over where the driver's feet would be for the ABS unit and controller you need to remove. You may want to consider getting an assistant with a little more experience in under hood wrenching before you attack this however.
Look again at Vic's instructions. The turbo/non-turbo and 850/V70 ate not that different They should give you the reference you need to locate the area you'll be working in.
Bon chance, Larry
