ANSWER : Hi there. Thanks for writing in, but unfortunately, we only offer mechanical repair and service tips on cars, small trucks and SUV’s sold in the United States. As much as we’d like to assist you trace this service light problem for your Pete, we’re probably not the best source of information in this case. There are several Peterbuilt online forums online where you can consult with certified big truck diesel technicians to receive help for this issue. Best of luck to you.

ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : The infamous "loose gas cap code" is P0442. P0434 is an issue with a heated catalytic converter not coming up to temperature quickly enough. It can be caused by the fuel injection being too rich. If you starter is not turning your engine over, the issue could be a dead battery.

If you can get it jumped off, most auto parts stores will check the battery for free. They will also, time permitting, check your engine codes for free. This will help guide diagnosis for whatever else is still wrong with your vehicle.

If you need assistance with the repairs from here, I would recommend having your Check Engine Light inspected by a certified technician, like one from YourMechanic, to diagnose the problem, get an accurate assessment of damage and cost estimate for repairs. YourMechanic can dispatch a mobile, professional mechanic to your location for this repair.

ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

ANSWER : It is possible that your vehicle’s PCM has failed. This is somewhat of a common problem amongst many GM vehicles. If the computer has failed, this could be one of the reasons that no trouble codes are appearing and the fact that the problem is intermittent. It is possible that the computer is somehow getting overheated and by stopping the vehicle for a short period of time, the PCM cools down allowing the vehicle to run again. I would recommend having your PCM tested for proper function by a certified technician with experience in computer diagnostics.

ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.
