Your heater core is leaking. The smell and smoke is from the coolant evaporation.

SOURCE: volvo s70 radio code

You must take the car to a Volvo dealer so they can reference the code from the VIN number. If you call it in, they only assume you stole the radio. Sometimes you have to prove you own the car.

I have a 2000 Volvo S70 as well with the same code. Do you ever have trouble starting your car? I did and that's why I took it to the dealer. Appartently it's the code for the ignition immobilizer system in your car (part of the security system). Specifically, a part call the antenna ring. The antenna ring is the outer portion of your ignition switch on the steering column - the part that lights up and has the following printed on it: 0 - I - II - III. This part is actually a sensor that transmits the code stored in the microchip inside of your key. When this part goes bad it fails to transmit the correct key code to the computer, and cuts the fuel to the engine.

The dealer wanted to charge me $550 for a new antenna ring, two new keys, and software to program the car's computer with the new key codes. I purchased the antenna ring online for $50 and did it myself in 15 minutes - so easy. They claim that you can't replace the antenna ring without new software - lie! You only need the software if you are replacing the keys.

Car is running great.

What are the probable causes of DTCs P0014,P0300, and P1358?

Please refer to the links below for definitions and poss causes.

Random/Multiple Cylinder Misfire Detected


the engine may be harder to start the engine may stumble / stumble, and/or hesitate other symptoms may also be present


A code P0300 may mean that one or more of the following has happened: Faulty spark plugs or wires Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector(s) Burned exhaust valve Faulty catalytic converter(s) Stuck/blocked EGR valve /


If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Dependin


Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly. A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the .box1 { overflow: hidden; position: relative; border: 1px solid #CCC; border-radius: 8px; padding:10px; background-color: #efefef; color: 000; margin-top:10px; } P1358
Trouble Code:
P1358 - (Manufacturer Specific)
Ignition System or Engine Misfire

DTC Description: (Cylinder No.2) - ignition Circuit Open Circuit

Likely Cause:

Cylinder 2
Open Circuit


Site Instructions:

  1. Please note the list of automobile manufacturers at the left edge of the screen. The currently selected ODB code is for the Volvo family of autos. The codes for any particular vehicle make and model will be found under the manufacturer family, i.e. Dodge and Plymouth are part of the Chrysler family of cars and trucks.
  2. Also notice that just to the right of the manufacturer family list is a short group of OBD II codes. The highlighted Volvo OBDII code P1358 in this list is the currently selected code, and the information on this page pertains to fault code P1358. The other codes in the list above and below this code are OBD2 codes some of which may be related to the current trouble code and can be navigated to directly.
  3. Need to look up additional OBD II Trouble Codes, use the search box. Enter the 5 character fault codes in the search box and submit the search. You can repeat the search as many times as you need, one diagnostics code per search.
  4. Don't assume a particular OBD2 code means the same for other auto manufacturers as there are many manufacturer specific codes in use.
  5. If your fault codes are for a different auto family, select that vehicle series before searching for the diagnostics codes because not all OBD2 codes used by one manufacture are used by the other manufactures. The search only looks at OBD codes valid for the currently selected manufacturer family.
  6. If your automotive family is grayed out, the current OBD code, P1358, is not among those used by the current manufacturer. You can click un-gray at the bottom of the auto family list and then select the manufacturer for your vehicle before searching for your trouble codes.

I have a 98 Volvo S70. A dashboard light that looks like a square with a fan in it just came on. What does it mean ? I have no manual to look it up

This light is the check engine light, its a picture of an engine, this is to let you know that theres a problem with the performance of the engine, what happens is that the computer is always monitoring all sensors and components and when its sees something out of spec it turns on the eng light and stores a code. the code well tell what part of a system has failed, for example it may say po301 cyl # 1 misfire. this would mean that the computer has seen cylinder 1 misfring , then with some checking and testing the problem can be found why the cylinder was misfiring, the first step you would need to do is have the compuetr scanned to see what code or codes are stored. there are many autopart stores that will scan the computer for free and give you a print out, if you could get me the codes i would be able to help you further, good day.

Why do the check engine light stay on? volvo 2000 S70

Your engine's computer is seeing data from the engine that it considers out of the normal on your vehicle. Any automotive repair shop will be able to scan the computer for the trouble code for you. Autozone will scan the code for free, however, you will still need to bring the trouble code print-out to a well qualified technician to be able to tell you what the potential problem may be. These codes can indicate anything from a loose gas cap to random misfire in the engine.

does this model have an ETS on it? Electronic throttle system. I could need a new throttle body. Sometimes the software goes bad and it will give the symptoms you described.

check your wire harness on the top of the engine. Volvo must have bought harnesses from Mercedes. The insulation just cracks and disintegrates, then the wires short. Not good for an ignition system.Once they short It can fry the circuit for that cylinder in the computer. Does not set a code other than Misfire.
