I recently bought a VW Caddy bakkie that has a Jetta 3 engine and Golf 1 gearbox. It is fitted with a Go-Tech Fuel Management System. The bakkie performed well for about 50 km, and then started jerking aggressively at low speeds, but above 100 km/h it jerks only occasionally.
I really did not want the modifications, but just liked the bakkie as it is perfectly restored. Should I remove the Go-Tech and replace with it with a standard fuel management system? Failing that, how can I resolve the problem without spending unnecessary money, i.e. without having it tuned again?

The Go-Tech unit is an engine control processor that enables a mechanic to change the mixture and ignition settings by using a laptop plugged into the system while the car is running on a chassis dynamometer. This method of tuning relies heavily on the knowledge and experience of the mechanic, so it’s very likely that he has made a mess of the settings. The least expensive way to sort out the jerking is to get a Go-Tech agent to have another go at setting it up.
In the long run, and for the sake of engine and drivetrain durability, it is advisable to revert to the standard system. A Go-Tech agent should be able to disconnect the system.
