Fairly compitent DIYer. Lots of experience working on cars from the 60s and items on the new cars that range from entry-level to intermediate complexity. Can probably do more but usually don't have the necessary diagnostic equipment or specialised tools required.

Question Answered: 

You can get used CCMs for $50-$200 on eBay and at various junk yards. Do you have the wherewithal to change it yourself? You will have to get someone who can download software to adapt the new/different CCM but that isn't as big an issue as it would be if it was one of the many parts that require software and the engine won't run until it has been adapted/downloaded.

234 is an over-boost event. It could be the TCV - they do weaken and/or fail but that usually results in under boost. It sounds like you might very well just have a clogged fuel filter. It happens with cars this old and simply throwing cleaner in the fuel tank can actually make the problem worse by freeing up other contaminants that get caught in an already clogged filter. Also make sure that your air intake is nice and clean and no vacuum hoses are off or leaking. These things are easy to check and inexpensive to change at your local oil & lube place or by a DIYer. That's a pretty simple and inexpensive way to start. If that doesn't fix the problem then you probably need someone who has the instruments to test the various turbo and fuel delivery components.

Question Answered: 

The ETM recall was associated with a different throttle body than the Bosch that is on your car. The only 2002 V70s that had the problematic type of TB were the carbureted models, not your Turbo. The problem could still be ETM but not near as likely as in the prior years with the different part. It could also be the Mass Air Flow (MAF) sensor which is pretty accessible and easy to clean -- assuming it isn't already beyond that and needs replacing. The other thing that can cause a fuel error and even put you into “Limp Home” mode is a clogged fuel filter. You won’t fix that by dumping cleaner into the tank either – you’ll need to get it replaced. Of course the real answer is not to just guess but to get the actual Volvo codes. You can probably pay a shop to pull them for you and you’ll also get all of the other codes your car is throwing off and might need fixing as well. The location of the TB can be found here: http://www.volvopartswebstore.com/showAssembly.aspx?ukey_product=1140810&ukey_assembly=242255&ukey_make=865&ukey_model=12012&ukey_driveline=0&ukey_trimlevel=0&modelYear=2002 Good luck.

Question Asked: 

I can set the clock though it isn't always easy to do. Sometimes it does what it is supposed to when I turn the "stick" and other times it just takes off running forward at full speed no matter which direction I'm turning the control. When I do get it set it may only stay set for a couple of hours, sometimes longer, before it takes off and advances to another setting.
