If you have the 2.5T model, there is only one cat and it is after the turbo. The cat is directy welded to the downpipe so you'll need to get to a muffler shop to have the work done. An after market cat should be available for under a 100 for parts.

Hi Kacie. Pretty much the only thing to do is remove the harness you spliced into the incorrect harness and use crimp connectors (the GOOD ones, not those cheap plastic blue ones) to match wire-for-wire and restore the original circuitry. THEN have at the correct harness and reinstall the stereo wiring. It's a PITA all right, but it really is the best way to fix your problem. Sorry about the bad news... -Steve

Yes you can, but depending on the issue it's not always a good idea. The Check Engine Light (often called "CEL") means there's something wrong that affects emissions, so it can be something as simple as a gas cap that isn't tight enough, to O2 sensors going back or vacuum leaks in the intake. The BEST way is to find someone local or a dealer to use the VOlvo tool (VIDA software with the DiCE interface) to read out the actual codes the car is giving you. That will tell you what component has failed or needs work, and you can then start fixing. If the car runs fine and doesn't stumble or otherwise act up, check the gas cap and if that ends up being the issue, it usually takes five drive cycles (ignition on, start engine, drive somewhere and no error) for the light to go out. Otherwise you can disconnect the NEGATIVE battery cable - there's a process, but basically, make sure the car is OFF (key out of ignition) for AT LEAST 10 minutes before disconnecting the battery! Then let it sit 30 minutes and reconnect it and see if the light comes back next time you drive it. Good luck!

There is no room for error...... Zero clearance. If off one tooth it can and will bend valves. if you are one that just feels the need to get alittle dirty or just can't pay for the service, then get out your Haynes out and turn to .....Tune up, and look at replacing timming belt. Get a cam gear tool that locks them into place so as that they will not move when u have them lined up. make sure they are lined up with marks as said in book. then make sure crank as well as all marks are lined up acordingly. make sure belt marks are lined up with everything. i would reccomend using a volvo belt though cause it will have all the marks on it.However other company's make good quality belts also at a fraction of the price. So it is really up to you.
Good thing when doing timming belt is to also change out your timming belt tensioner. YES do this it will save you a engine in the long run. it is a moving part that will go bad, it will freeze up and snap timming belt. rip out teeth in thebelt and bend valves. So as a gen rule...When you change timming belt, Change belt tensioner at same time since you cant just change tensioner without changing or getting timming belt off. Remember to use your HAYNES. It is your friend and will save you money in the long run. Good luck... Hope this helps you.

immobilizer.. dealer needs to reprogram key. they charge a little over $100.

sounds like a bad relay

screw it back on

This sounds like the ever familiar ABS modulator failing. However, VADIS doesn't list a OEM code with P1633 (it goes from 1632 to 1635). The 16xx codes normally relate to CAN bus or an individual controller. All ABS warning lights go through the ABS module, which is why you are seeing all three of those lit up.

check if your car is fitted with ignition coil (s). If does the coils are the problem What about the ignition fuse if is blown.

sender unit most likely at fault

Could be your turbo vacuum intake is clogged check the filter and the intake.

If you are technically minded buy a bluetooth OBD2 plug and download Torque Pro Android app. This will allow you to reset the codes yourself and ensure there is a genuine fault and not an intermittent issue. Cost was around $30AUS.

On Youtube, search for "throttle cable replacement volvo". It might help.

Check idle air control valve.

this light comes on when you first start the car but it will go off when you reach a specified speed for your vehicle it is just a reminder
