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.

Overheating and fans failure

Volkswagen Beetle 2000  200000 miles
Hi everyone, I have a Beetle 2.0 and its engine overheats. Apparently, water is not flowing properly, so it seems to be a failure in the water pump. When starting the engine, the ducts from the radiator's entrance are fulled with pure vapor and the hose that leads to the water deposit is not blocked, but still water does not leave when accelerating. The fans do not start working either when the car overheats. The fuel pump has already been replaced but without positive results. Might it be that the new pump is damaged as well? How can I make sure it is not the head gasket that is failing? How can I notice whether the pump is working properly? Thanks.

You should check that hose you are talking about, the one that leads to the water deposit. It usually happens that it blocks on the engine head's side.

First, leave the engine warm up a bit, pick up the hose from the inferior and superior radiator and, if only one of them is hot, it might be that the radiator is damaged or dirty. If not, if your fans are not working, check the engine temperature switch, disconnect it and, using a wire, link the two connector terminals. If they start working, replace that switch.

If it has a cheap water pump fitted Iv seen the plastic wheel on them break up or break off but not cause any leak. I’d check a few things with this issue remove the thermostat place it in a kettle and boil it see if it opens or simply replace for about £8 flush the radiator to check for blockages. Test the fan actually works get a power probe put positive to the fan it should spin. If it doesn’t replace the fan if it does check fuses and relays. Check heater matrix pipes on back of the engine could have previously had loads of k seal placed in it and it’s all blocked up you can flush it with a hose to test. Get a decent mechanic or buy a decent leakdown tester twin gauge from eBay £40 requires use of a compressor. Place engine to top dead centre make sure all valves are closed. Remove spark plug or glow plug and insert gauge. Pressurise the head. Check for bubbling in the coolant check for compressed air leaving via the exhaust. This will determine the condition of not only your engine but the head and inlet and exhaust valve. Great bit of kit. If your local to york I’ll hapily perform that test for you. Regards Andy.

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
