It is highly probable that the reason your car was reluctant to start was that the time you were running diagnostics had sapped some of the charge from the battery. The battery on the car will not charge unless the engine is running. It is unlikely that this device would harm your vehicle but it is theoretically (and practically) possible to do temporary ...

To my knowledge there is no way a scanner can cause issues with your computer electronics. This device is a read only device. It doesn't change anything in your computer. It does, however, communicate with the computer. Through this communication it can give the computer commands, such as to clear the codes. This doesn't write anything to the computer, but ...

No. The tool in and of itself cannot do any "harm" to the vehicle. If you were testing apps with the engine off, it is quite possible that the battery may have drained to the extent that it gave some hiccups while starting. Low fuel level may also be to blame here. However, If the vehicle has error codes present which are cleared with the tool, the ...

One of my tires will need replacing soon as well as it is almost at the legal limit. I have a good amount of tread left on my front two tires. I am going to replace all four tires as soon as the worst one is due for a replacement. I want to clarify that you should never replace only one tire on an axle, you must always replace them in pairs at least ...

Regular service and fixing what's broken will keep just about any car running for a long time. The main difference with driving shot distances, is that your engine spends more time at less than optimal temperature. This is not as big a deal with modern fuel injection engines, but parts may still wear out faster than vehicles with mostly 'highway miles.' ...

Putting your best tires up front is the exact opposite of what every tire shop I've ever been to in the US will do. You should not put your best tires in the front unless you never drive in adverse conditions like rain or snow. This popular mechanics article sums it up pretty well: The truth: Rear tires provide stability, and without stability, ...

The S80 from this period had a high failure rate of ABS modules. Your symptoms seem to match this problem. A failing ABS module will show brake errors and corrupt instrument panel data (lights, speed, temperature). What would help if you read the fault codes before disconnecting the battery, as doing so clears them before you can take a look.

My suggestion would be to chase the wiring directly rather than trying to identify all the parts of a system your mechanic did not even identify for you. If possible, find an electrical diagram for the car online. A Google search for 2001 volvo v70 wiring diagram turned up many images of wiring diagrams that should be very helpful. To trace this back, ...

You can find the parts list for Volvo online here. The link of interest will be Home> Volvo> V70> 2001> Electrical system> Switches, turn indicators, main and dipped beams, WIPER/WASHER And it looks like the smallest part they sell is the entire turn signal switch. It looks like they run between $67 and $148.. Hmm.. not cheap. The price depends on the ...

Almost certainly a poor connection within the bulb holder. You might be able to clean up the connections within the holder with a fine bit of sandpaper or "wet and dry", then adjust them with a tiny screwdriver to improve the contact, but it's probably easier to get a new unit...

In my personal experience, having used cheap tires myself once, I'd say don't put them on the rear. If you use them on the front, the car won't have as much breaking power and might tend to under steer. Both of these things can be compensated with a more defensive driving style. If the car starts to under steer you'll feel it and slow down. If your rear ...

Just grabbing the first 2002 Volvo Replacement Headlamp I could find the headlamps run at 12V/65W, meaning it would draw 5.4A of current. If you hooked up a 1k resistor and ran it straight to ground while the lightbulb was on, that resistor would pull 12mA of current, adding an additional 0.2% load to the battery. From the car's perspective, you'll be fine....

The part image in the link shows three wires: green, white and black. Combining the image with this blogpost, which explains how to hardwire the 240 taillights, the green/blue is a signal wire for the turn indicator, black is ground. White is purportedly not used: Options at your disposal Source the connector pair and solder/crimp them in place ...

If you are looking for a method by which you can diagnose the problem to confirm your suspicions that one of your keys has failed I can suggest the following. In close proximity to the ignition barrel, literally around the outer radius, is an RFID reader. When you place the key in the ignition, this energies and attempts to rear the transponder code from ...

There isn't a mechanical relay it's all controlled by the Guard Lock and Alarm module. Gain access to the module and test for power on pins A26 (green/red) B1 (red) and B8 (white). Test for ground on pin A1 (black) If you don't have power on those pins check fuses 7 & 8 in the under dash fuse box. And fuse 9 in the engine compartment fuse box. If you ...

Sounds like he bought a new battery to try to fix the issue but it did not. There may be other causes (like fuses, wiring, a non-genuine immobilizer) but the next logical assumption is that the starter and/or starter solenoid have failed.

Depends on what you would like to do with it. If you just want to clear some generic codes and the check engine light, then most generic OBD2 cables should work with appropriate software. If you want to do more advanced things, like reading Volvo specific codes or changing available parameters then what you need is VIDA + DiCE. It's a Volvo diagnostics tool ...

From what I can tell, the 05 uses CAN protocal, not OBD2, and then there are some issues with using a generic tool, and most accepted, if not only official method, is to use a volvo-specific (proprietary) scan tool to read the codes. Look over the link below and it appears that there has been some headway made in adapting a 'generic' scan tool to work, but ...

It depends whether you like understeering or oversteering. I think understeering is more preferable over the other due to thing needs to be done to gain the steering control is simpler; slow down. Correcting/recovering the oversteer with over 1000 degree turn steering wheels nearly impossible. You need to be quick as a snake :) to introduce correcting ...

On a FWD car always have the best tyres on the front. The tyres on the front are going to do all the steering, handle all the acceleration forces and 80% of the braking. I would definitely want my best tyres for that. Any worries about bad tyres on the back causing over-steer are unfounded unless they are in terrible condition and you drive like a lunatic. ...

You can use the trunk. The reason they say not to use it is for your safety so you don't shock yourself. If you're capable of hooking up jumper cables and have decent access to the battery it's perfectly acceptable. Many Mazdas, Chryslers, BMW, and Mercedes all say to use the engine bay because the batteries are under the seats or in the trunk; It's just so ...

It has to get HOT. As you seem to know and elude to by asking if sitting and idling at a higher RPM could resolve the issue. If the car is fit can you just drive it in a lower gear at a higher RPM? Not savagly high like a teenager but reasonably high. If you would be in 5th on the freeway can you drive it in 4th? Some DPF's can get seriously clogged up ...

Does the air blow cold? When refrigerant gets low air blows hot. You can always buy a can of refrigerant with the installation nozzle, check the pressure and if low fill or if not return for refund. This should help you start to diagnose your problem and check possibilities off the list. From my experience the heater/ AC controller can go bad, swapping ...

I don't think a battery with a higher CCA is going to help, but a new battery in and of itself might help. I'd have it tested and see if it's voltage is where it needs to be. If the battery is worn out, you might be seeing the issues you are having. Putting a higher CCA battery will not do anything to improve your situation, unless the one which is in it is ...

Ultimately, traded it in for a 2012 Chrysler Town & Country Touring L. I had three estimates on the work, and the cost-benefit analysis demonstrated keeping the Volvo wasn't "worth" it. Considering the negative equity incurred by repairs, and that the car didn't meet my needs even with positive equity, it really was just time to let it go.

Almost always the problem with the FOB is that the conductive carbon coating on the keypad wears out. If you replaced the battery and it still doesn't work, try this. Take the fob apart, and you'll see a circuit board under the rubber key pad. The circuit board has a mesh under the rubber contact for unlock, start, etc. Take a screw, or a rolled up section ...

If indeed it checks out and you need to replace the camshaft oil seals, check the PCV system too. If it gets clogged and stops functioning, excessive crank case pressure can squeeze out camshaft and crank seals which will make for recurring and potentially catastrophic failure. Which engine does your XC90 have? I use my S60R 5cyl as reference.

My S60R had the same problem on the driver side window. Hold the button fully in order to close the window, but hold it when it gets to the top for 10 seconds. You will hear the window "nudge" from inside the door. Then immediately release and fully press the button again. It should now go up and stay up when using the auto function of the switch. It seems ...

Agree with @mac & @ChrisMcKeown ... one of your sensors is telling your computer one of your wheels has stopped spinning and therefor is activating the traction control. Figuring out which wheel sensor is bad will be tough to figure out. If you don't have the right diagnostic equipment available to you, it will require a trip to the mechanic to get it ...

Omg..a friend thought my car not starting sounded like a security issue with my key fob and recommended that I google my problem. I have a 2006 Volvo S40 and I found others had this same exact problem. I gave the screwdriver method a try and it worked! Crazy but so glad I found this exchange, thank you!
