Stalls after 45 minutes of starting

Volkswagen Beetle 2000  210000 miles
I own a Beetle 2.0 year 2000 and it stalls after around 45 minutes of starting it. I have already changed its coil, camshaft and crankshaft sensor, fuel pump, relay 409 and throttle body but it keeps turning off suddenly. I've been trying to find a solution for a month and a half but without positive results. Does anyone know something about it?

I had the same problem with a Beetle 99 and it was solved when a piece, which I don't know the technical word, that is in charge of controlling the air flow to the engine, was replaced. It is an electronic gadget and in my case it was burnt.

The name you are searching for must be the MAF sensor.

Turns over but won't start

Volkswagen Beetle 2004 Convertible 04 beetle. 1.8 turbo 75000 miles
My car stalled in the middle of the road, tried charging it and nothing so I replaced the battery and it still won't start. It tries but just doesn't catch. It made a weird noise like it was grinding I know if it was the alternator it should still start (I think anyways). My dad said possibly timing belt or some sensor. Please help me figure it out if anybody knows about this

My 2001 beetle did the same thing. Turned out was timing belt. If you have an interference engine it's a 50-50 chance valves got damaged. I lucked out since my husband is a mechanic knew right away. The more you try to start it the greater the chances of damaging the valves

Random misfire on random cylinder.

Volkswagen Beetle 2000  190898 miles
2 L inline 4 2000 year. No fuel pressure unless you block the fuel return line. And a random misfire on at first piston 4 now on piston 1? the coil pack was replaced with new, new sparkplug wires, new temperature sensor, replaced the fuel pressure regulator. Problem persists... low to no power on acceleration can move car when rpms are slowly raized but only up to 3000 rpm. If you block the fuel return line can accelerate but the fuel pressure will remain at 80 psi, standing fuel pressure is at 38 psi; when vaccuum line to fuel pressure regulator removed the standing pressure goes to 48 psi.
No hair left on head because of scratching...

The ignition cylinder won't turn engine over to start or to turn engine off.

Died while driving won’t start

Volkswagen Beetle 2001  140000 miles
Just died won’t start. Replaced fuel pump still won’t start... obd2 code P0135 which I had before died. (Comes on and off).

Will a code show up for “crankshaft center sensor” or “camshaft sensor” on my code reader while just cranking engine over? How about bad computer?
I’m a backyard broken mechanic. Thanks

Intermittent black smoke

Volkswagen Beetle 2007 Convertible 2.5  100000 miles
Was leaving to the store, got 1/2 mile down the road when I see a huge cloud of black smoke coming out my exhaust...car started to act like it was going to stall but didnt... I pulled over until the smoke cloud cleared and proceeded to drive back home and it was fine. This keeps happening every 5 miles or so... No warning lights came on on the dash so it's not throwing any codes... I changed the air filter, cleaned the MAS sensor ( i think thats what its called) and went and bought a Dorman PCV valve replacement kit and had that installed...Now today it's more of a white/ gray colored smoke out the exhaust. Had it tested for a cracked head gasket and that was negative...HELP!
