VW Tech Tip: No Start/No Crank On Jetta’s Keyless Start System
The customer may state that the engine cranks intermittently or will not crank. This condition may be more evident when the engine is hot. This may be caused internally when the steering column electronic systems control module – J527- fails, causing Terminal 50 to not energize high, which results in a no-crank condition. Models affected: 2005-’07 Jetta (A5) and 2006-’07 Rabbit and GTI (A5).
Bosch Introduces New Start-Stop System With Coasting Mode
With its new start-stop coasting function, Bosch enables drivers of vehicles with combustion engines to travel in zero-emission, noise-free and low-resistance mode over large parts of their journey. This new technology stops the engine when the vehicle is in motion, so that it does not consume any fuel. Whenever the vehicle can maintain its speed simply by rolling – for instance on a gentle incline – the engine is stopped. As soon as the driver touches the gas or brake pedal, the engine starts up again.

Winter Starting And Charging System Maintenance
In addition to checking the strength of the antifreeze, a cold-weather starting inspection should also include testing and visually inspecting the battery and cables, starter, alternator and changing to the auto manufacturer’s recommended engine oil. Because cold weather slows down the chemical reaction between its electrolyte and its battery plates, the average battery can lose more than 50% of its cranking amperage at 0 degree F. For that reason, cold-weather starting quickly separates OE-specification from non-OE-specification batteries.

Diagnostic Dilemmas: Solving Late-Model Charging System Dilemmas
This month’s Diagnostic Dilemma involves a pristine 1995 Buick Park Avenue with a customer complaint of dimming instrument cluster lights, a flickering voltmeter needle, a driveability bucking complaint and a dead battery. The alternator had been replaced due to an indication of excessive AC ripple on the shop’s hand-held battery and charging system tester. A P1630 trouble code was present, indicating a high/low condition with battery voltage.
