Whether you personal a Golf, Jetta, or GTI Mk4, it is getting previous! So more than doubtless you are driving around fumbling with the controls at night making an attempt to pick the right vent setting with no mild, or your bulb is slowly but certainly getting ready to die on you.
In order for you to find the damaged circuit or bad connection, you have to use the wiring diagram. Start at one finish of the circuit and look for voltage and ground. If it is not there, test the opposite finish of the circuit. If there’s ground and voltage, you could test the center of the circuit. If there isn’t any power or floor, then the problem is in the first half of the circuit. Hold dividing the circuit in half until you find the problem.
GinaB – I do not know if it’s common or not with the Toyota, but the problem might just be a foul connection with the wiring harness connecting the knock sensor. It might be worthwhile to attempt changing the wiring harness, which prices about $a hundred and sixty. Ask you mechanic about that. It’s labor intensive to interchange the sensor and may total $600.
Hey Okotoks, OK, first I would test to see if the wheels are tight, a 25 mph vibration is unusual. If the wheels are tight, you might have a bent rim, so examine your rims for giant dents on the within and outer bead. If that is OKAY, it is potential that you might have some corrosion or rust built up between the rims and hub/rotors, this is able to trigger an uneven torque on the wheels and a wobble within the wheels. If that appears okay, you have something bent in the suspension. Let me know what you discover, Okotoks, I’m very curious, thanks.
Have you learnt if the rotors had been changed or resurfaced? If not, it may be rust on the sting of the rotor inflicting the press noise. One other chance is the rotor backing plate can get bent during a brake job, if that’s the case, it is just a matter of bending it out of the way in which. Another risk is the anti rattle clips within the caliper could also be out of place or put in flawed, it could be hitting the rotor inflicting the press noise. I might bring it back to the shop and have them test their work.
