parts common to rabbit jetta golf fox scirocco `77-92 daily driver section brains brains who s got the brains auto repairs then now like it or not your vws® are becoming more and more electronic devices the good news is it has allowed engineers to increase performance and efficiency at the same time this feat is accomplished at a time when government emission and safety regulations continue to challenge them the bad news is that the automotive service industry has not kept up with sophistication of the cars because of this many and i mean many mechanics mis-diagnose problems we don t necessarily mean the do-it-yourselfers but many of the nightmares we hear about involve the professionals so you ve got to have a basic understanding of how your car works to be able to evaluate your

you have diagnosed the failed component we can provide you with excellent recycled components off cars we have taken apart we can solve your problem for a fraction of dealer s prices on some items we may suggest new or even remanufactured components as availability dictates we will always save you money these control modules engine management and anti-lock brakes electronic transmissions onboard computers collect information and respond with output in a pre-programmed manner this pre-programming has given the engineers very precise control over vehicle systems changing this programming after-market performance chips has given the modern hot -rodder a unique way to improve the vehicle s performance but not necessarily its longevity the electronic control modules ecm or electronic control units ecu are the gathering point for electrical signals that come from a variety of on-board sensors these sensors detect everything engine rpm to temperature wheel speed throttle position to electrical load etc you get the idea electronic control module if a control module is malfunctioning it can be a serious problem we take the electronic components out of good-running vehicles and sell

coolant-temp sensor to tell the fuel-injection computer what temperature the engine is running at the sensor does this by sending the computer a resistance signal in ohms that changes with temperature the computer then adjusts the amount of fuel sent to the engine based on this signal the symptoms of a bad coolant temp sensor can be an engine that starts hard or misses when cold but runs fine when warm another symptom is an engine that loads up the spark plugs and runs rich for no apparent reason ignition good you can easily test these sensors with a simple ohm meter the resistance values ohms are in the a bosch b motorola cnew bosch bentley manual and a new coolant temp type type type the voltage regulator s duty is to make sure the sensor is relatively inexpensive you can current produced
