why does my engine keep changing to something else even after I correct it ?
My engine is 2. but keeps changing to a 1,5 diesel

The 1982 Volkswagen Vanagon was a rear-wheel-drive vehicle that could carry seven to nine passengers. It was powered by a 67-horsepower, 2.0-liter, air-cooled four-cylinder engine with fuel injection. A four-speed manual transmission was standard, while a three-speed automatic transmission was available as an option.
The Vanagon was also available with an efficient 2.0-liter, water-cooled diesel engine that generated 48 horsepower. The diesel Vanagon is distinguished by its dual front grilles.
The Vanagon was fairly well equipped with rack and pinion steering, power-assisted brakes, and front and rear independent suspension. Standard features also included front bucket seats, a rear window defogger, two-speed windshield wipers, vinyl upholstery, and a folding rear bench seat that provided additional cargo space. Air conditioning and a rear window wiper were among the options.
In addition to the standard model, a Vanagon Camper version was available. It came with a pop top, a rear seat that folded out into a bed, a refrigerator, a stove, a sink and a pantry.
Drivers noted that while the Vanagon handled well, it was underpowered and would not win any races. One benefit of that low power was good gas mileage, according to a number of drivers, who also appreciated the Vanagon for its versatility and comfort.
