Once that happens, he stops, leaves the car in the park, turns it off and restarts it, and he’s fine until he starts up again in about two weeks.
We took it to a qualified VW dealer, who couldn’t find any error codes and spent time trying to recreate the condition without success. This is a security issue and we appreciate any recommendations you have.
A: This model, like many Volkswagens, uses a key lock and an electronic guide wheel locking module. I suspect the locking module has an intermittent failure that causes the engine to start but does not allow the guide to unlock.
There doesn’t seem to be an undeniable approach to diagnosing this, whether it’s a module or a wiring defect.
I would go back to the Volkswagen dealership and ask them for the module. Also report the challenge to nhtsa. passv/report-a-safety-challenge.
Q: I just bought a Saturn Outlook 2008. The dealers said I would not sort the battery and tried two alternators and batteries. So, the idea is a simple solution of a fuse or a defective mass. That was a month ago.
I learned that the charging formula is controlled through the computer. I checked the masses and replaced the fuses, as well as the existing battery sensor and tensioner belt. Still, the alternator does not charge.
Is it a faulty computer or is there something else?I ordered a GM Tech II research tool, which may be just for me.
A: It turns out that you have done most of the work with strength and grounding, such as making sure the alternator is grounded. The load signal is sent to the ECM (engine module) and BCM (body module) and, depending on the signal, it will find out how the alternator is charged. Like maximum ECM devices, it uses a 5-volt reference signal.
While it may be a faulty computer, most clutter is due to broken or corroded wires. Having a GM research tool compromised (even one like TECH II) would be helpful in checking the charging formula and battery codes.
Q: I have a 2007 Buick Lacrosse. At every oil change, I decide to use artificial oil. Is it necessary? Or can I switch to normal oil without problems?
A: As long as you use Dexos through General Motors, you’ll be fine. On the other hand, artificial oil is better than regular oil, reduces wear and tear and allows for a less difficult start in bloodless weather.
Q: I only have snow tires on the front of my front-wheel drive Toyota Corolla SE. Snow tires are expensive, so I’m looking to make do with snow alone in front. I was told I have 4 snow tires.
If I drive too fast in corners, I have a tendency to fish in the snow. Is there anything I can do?
A: It is preferable to have 4 matching tires.
Putting snow/winter tires in front of a front-wheel drive car can cause it to travel through snow, but braking will suffer. My suggestion is to get two extra snow tires and an extra set of wheels. The passage of winter tires will be more economical. In addition, through its winter tires, it will extend the life of its summer tires.
