I am a former professional auto mechanic (Porsche and numerous foreign marques). I am currently a semi-retired computer programmer. My hobbies include motorcycles both riding and wrenching. Home automation. I like to pay it forward to the gear-head community what little I know. Having said that... I will not respond to rhetorical questions or blatant attempts to troll against my contributions. I periodically write articles on a blog about my projects. You may find those here: Timbocephus

"Why does my engine not turn over?"に関する回答Not sure what was replaced? Could you try to make that clearer? Did the starter itself get replaced?

"inserting audio jack phone switched off, mic and speakers not work"に関する回答Sounds like you fried the audio components of your phone. You might be able to get it to work with bluetooth if you dig around in the android settings long enough to figure out why that BT mic won’t work. Note the BT mic may be a victim of the overload you did trying to run the computer speakers not sure though. I have an x4 and the hands free BT works fine in my car infotainment system.
"printer doesn't turn on, red light is visible on left when opening pri"に関する回答Try providing pictures of your red light. Also tell us model of printer in question.
"New hard drive needing setup but has Ubuntu login?"に関する回答Have you tried using any bootable USB or SD cards to see if they will work as is? If you can get those to work there is nothing stopping you from doing a fresh install if you don’t care about the contents that are on it.
"No lint coming out on lint screen. What do I need to do?"に関する回答Check for blockage in the dryer vent to outdoors would be my first guess. Please discontinue using until you get that looked at. blocked vents are a leading cause for dryer induced home fires. You could turn it on to a cool setting and go out to the vent if you know where it goes and make sure air is coming out at a normal unrestricted rate.
"Plasma cutting depth and thickness"に関する回答I have heard of some older safes containing materials that you don’t want to mess with if you are a novice. I would consult with my local locksmith who I know to be an expert on older safes. Can’t answer your questions regarding plasma cutting equipment however. Movies tend to make stuff look much easier than it in fact is.
"Ignition key was stolen on 1996 vw golf"に関する回答You could but changing ignition lock cylinders is pretty difficult and will no doubt cost more than getting a dealer to provide you with the key codes. Once you have the key codes you can get a locksmith to cut you a new key pretty cheaply. I recently bought a high mileage toyota tacoma and had to have new keys made in order to get the door lock cylinders to work properly again. The only key I got with the vehicle was worn so badly that it no longer worked the door locks without a major struggle. I did have to provide the dealer with proof of ownership before they would release the codes to me. I had two keys made at local locksmith shop for less than $20 try getting a replacement ignition set for that price! Also if you go your suggested route you will still not be able to operate the door locks!
