Phaeton :: Brake Pulsing At High Speed Between 60 And 80 Mph
When I apply the brakes moderately at speeds between 60 mph and 80 mph, the brakes pulses and the car shakes. If I press harder, the intensity gets worse shortly and then disappears the harder I press. The front steering wheel does not shake so I believe it is the rear brake or wheels. This problem started after I changed the rear VW brakes rotors and rear VW pads and changed all four wheels with remanufactured VW Phaeton wheels. The issue must be with the wheels,brakes, or lug nuts. The tires have not been changed but they are fairly new from what I can tell. The front rotor and pads was changed by the prior owner and I've never had issue with them, they are fairly new and look to be OEM.
Prior to reinstalling the new wheels, I cleaned the rust off of the front rotor surface that makes contact with the wheel and applied high temperature paint. One of the wheels I had a run in the paint (and there is no way I can make the paint 100% the same thickness) so perhaps this has slightly misaligned the front wheels to the rotors.
When I did the brake job, I cleaned the driver side rear hub of surface rust prior to installation of the rotor. I did not clean the hub on the rear passenger side because the hub and wheel bearing was changed a few months prior. I did snap the plastic for the speed sensor for the abs on the rear passenger side. I epoxied the plastic back together and have no ABS errors when the car is scanned. Everything was torqued per VW recommendations. I also checked the calibers sliding mechanism (for left to right movement if rotor slightly warped or out of true) and they moved freely and was not locked up. The only part of the job that was not 100% by the book is I used a hand made tool to push the pistons in on the calipers so I could install the pads (I had to push and turn the piston roughly at the same time but was not 100% at the same time because the tool was hand made).
I've had the wheels professionally rebalanced balanced at a tire shop with a fairly modern balancing machine (digital computer flat screen readout). Originally the wheels was balanced with an older balancing machine and when they rebalanced it it was noted the wheels was way out of balance. I had a bad steering wheel shake and the car vibrated significantly prior to the new balance. The shaking improved greatly with the rebalancing but I could still feel a subdued shake in the seat of my pants (steering wheel shake is gone). Yesterday, I retorqued all of the lug nuts and found the driver side rear and passenger side front had one loose lug nut. Also it appeared that the lug nuts may have been installed with an impact driver and probably not torqued because some were very tight. I used a dial gauge to check both the rear tires and I have about 15-20 thousands of movement in each wheel when rocked side to side and top to bottom. Prior to tightening the lug nut on the driver rear, I had 100 thousands of side to side movement. Car now runs much smoother (maybe not as good with the original wheels and brakes but pretty good) after retorquing all the lug nuts, but the same 60-80 mph pulsing / shaking happens when apply the brakes at speed, perhaps even worse.
I've also checked the rear rotor and wheel runout with the dial gauge and I didn't have anything over 4 thousands on the rotor or wheel when rotated. My jig for the dial gauge was not the best since it was hand made and was attached to the ground instead of the car, so any dial gauge measurements could be off, but I would think they tolerances would be even better if I had a proper jig mounted to the car (not floor). The only thing that I haven't replaced is the lug nuts. Tightening them did seam to change the brake pulse behavior for the worse but did make the car run smoother. Could it be possible that the lug nuts are stretched and this is producing the behavior I'm seeing? I've head the ABS can cause a shake if the speed sensor is damaged.
Phaeton :: 2004 V8 AWD Pulsing Vibration On Highway Speed
Ever since the day I bought the car, it has had a highway speed pulsing vibration. This vibration manifests once you cross about 90kph, and pulses like a sine wave.
Think of it like this - OOOOOOooooooOOOOOOooooooOOOOOOooooooOOOOOO - where big O's are vibration and little o's are absence of vibration.
I have had the wheels and tires rebalanced several times on various machines over the years in attempts to rid myself of it. The original owner had theorized that the car was so heavy and had sat on its aftermarket rims in one spot for so long that the wheels had bent, which does not appear to be the case. The dealer has experienced the symptoms but cannot find a cause...though I fear they are less knowledgeable about the car than I am. I note that several people on the forum have had vibration issues due to drive shaft bushing failures...but in skimming the relevant threads, none of those people characterized it as a pulsation OR a constant issue that I saw.
I wouldn't say the pulsing was fast...think 4-5 seconds of vibration and then 4-5 seconds of peace.
Phaeton :: Pulsing Ticking Sound Coming From The Steering
Funny pulsing ticking sound on full lock. Only noticeable when parking etc. But once it's started making it, it stops when the lock is unwound... but does it again without lock when the car reverses.
There is no feeling through the wheel or through the chasis when going forward... but subjectively it can be felt when going backwards.
Been getting a little bit more prevalent over the last thousand miles. Driving normally, steering feels perfectly normal.
I've checked the power steering fluid. If anything the reservoir is over full.. so it's definitely not short of fluid. Should the fluid be checked from unscrewing the dipstick.. or with is jut dipped in and not screwed up? Either way it's still over the max line.
Phaeton :: Pulsing Occur On Power Steering When Maneuvering At Low Speed
Some of you might remember I've pondered here before about the strange pulsing that occurs on my steering (on the V10) when maneuvering at low speed. It's always done it. Well, for the 18 months and 15k miles I've had the car.
Nobody (including Phaeton technicians) who have heard it/felt it have had any useful advice or insight (save offering to take the engine out to check on various bits).
I had always assumed that it was something like the load when the car is being parked etc was sufficient such that some relief valve was lifting momentarily and repeatedly. However I've come to realize that it is not just the slow vehicle speed, but engine speed too. Of course, nearly all parking maneuvering is done at tick over. But if I raise the revs just a little, the phenomenon seems to go away. Not easy to isolate maneuvering speed from engine speed... which is why I'd not really noticed before.
Phaeton :: Headlamps Shutoff When Driving Under Bright Street Lights
I have a Canadian imported vehicle that had the Driving lights on all the time. I turned off the DRL with the VAG with no issues. The last few months tho, the daylight sensor (which I believe is at the base of the windshield) has been very sensitive to street lamps and turns my headlamps off briefly. I'm curious if I can VAG this out as well?
View 7 RepliesPrius (2010-12) :: Pulsing Vibration In The Front Of Cab When Driving
My car is approx two years old. I bought it in the beginning of 2010. I rotated my tires about 10,000 miles ago after not rotating them for over 20,000 miles. initially the dealer said it was cupping on the tires but I have driven them since for close to 10k miles.
The same issue persists. Whenever I drive the car and it gets to around 30-40 mph accelerating or coasting I hear a very audible noise that almost sounds like pulsating vibration in the front of the cab. I've brought it to two different dealerships and they have both said it is the tire needing rebalanced but I somehow doubt that is the case.

I have recently noticed a noise... to describe it would be difficult, but I'll give it a shot. There is a pulsing sound, maybe coming from my front left wheel area? It happens when I turn left driving, even on the smallest curve. From what I can tell, the pulsing sound does NOT change speed when I speed up or slow down. My initial thoughts were a bad wheel bearing, but I'm not so sure. Could it be power steering?
My Kia does have 130000 miles on it, and I just purchased it used a year ago, so I'm not exactly sure what maintenance or repair has been done on it.

Montana :: Bosch 125 Amp Alternator - Lights Dim At Idle But Brighten On Acceleration
I just installed a new Bosch 125 Amp alternator about a week ago.
Puts out 13.9 to 14.0 at the battery with everything running at idle. When you rev the engine the head lights brighten for a moment then settle down to what might be considered normal. Battery holds at 12.6 volts over night and cranks no problem.
Only reason I replaced the alternator is because it is original and has traveled 280,000 kms already. Bearings were getting a little rough, although it seemed to be charging almost the same as the new one. (13.6 versus 14.0 for the new one).
Battery is 8 years old and has a 108 month 'life' to it, so should be replaced before winter sets in.
Could there be a problem with that screw on the back of the alternator referenced in a few posts, or is it possible that the battery is trying to say, 'I'm getting tired!'
Camry :: Clicking Noise At Alternator, Warning Lights On, Car Won't Start
Have a 2011 Camry base 6 spd manual. Came out from work and won't start. Electrical cutting on and off. Turn key and only only light comes on with clicking. Get a jump and it starts but all electrical comes on and off for five minutes until engine dies. Now won't start with jump and just makes clicking noise at alternator with lots of lights on and off on the dash. Seems like a major short somewhere.
New battery seems a waste at 2 years old and probably not the problem.
Ford F-150 - 1997-2003 :: 1999 - Random Misfire While Driving On The Bad Alternator
I have a 99 F150 4x4 with 5.4 Triton, 99xxx miles. I was towing my boat when the regulator in my alternator went bad. I drove the truck with the voltage being sporadic for about 10 miles until I could get to a parts store. While driving on the bad alternator, I started noticing a misfire. I replaced the alternator, battery and DPFE. I still have the misfire....but here is the kicker. The misfire only happens when the truck reaches operating temperature. Which, in my limited knowledge, eliminates a fouled plug, COP, bad injector and a vacuum leak. I've got no check engine light so I can't pull a code. The only thing I can think of is to clean the EGR?

I put a re manufactured alternator in my 2000 f150 with the 5.4 liter. Now all the lights flicker, go dim and then come back on bright again. I noticed when the lights dim, the heater fan speed also drops. The light flickering is constant and bad enough, that I can notice it in daylight also with the headlights on. It is really noticeable at night with the truck in drive (or any gear for that matter) sitting at a stop sign or sitting still in my driveway. I changed out the old alternator because it was making a loud chattering noise. I didn't have any trouble with the lights or fan with the old alternator. Why doesn't the battery volt gauge in my instrument cluster fluctuate all the time while it is doing this? It reads in the normal range all the time and doesn't move. The flickering lights are also noticeable at highway speeds, its just not as bad.

Driving home my radio quit working. I looked at the gauges and they all dropped to the left. The it looked like my lights quit working and then the truck just quit. All of this happened within 5 miles and 10 minutes. I jumped it and quit before I could even get going, it did start momentarily. Could not even get the gear shift into neutral; had to jump it to get that to happen.

Electrical-wiring - Acura - Rl - Gauges - Starters :: 1997, Battery And Brake Lights Came On After Alternator Replaced
I got my Alternator replaced last week. Last night, I hit a very small bump, not even large enough to really cause me to slow down, and as soon as I did, my battery and brake lights came on. My RPM gauge also jumped around and eventually went to 0 until I stopped and put the car in park. (The bump might just be a coincidence who knows). So after all this happened, I turned off my car, tried to restart and got nothing. Sometimes I get a click, sometimes 2 clicks up to 4-6 consecutive clicks. Every few times I won't even get a click, just a slight attempt to start, then the car dies, then 2 seconds later all my lights and radio etc. come back on. My problem here is a few things:
1. I've been told it could be the starter. If it's the start, those dashboard lights shouldn't have came on right? just the STARTING portion of the car.
2. I've been told it could be the battery.
Well If i got my alternator tested and Advance said it was working, Why would my battery be dead? And if it WAS dead, wouldn't my lights have went dim or something else happen to the car?
Ford F-150 (2004-2008) :: New Battery And Alternator / Passenger Airbag And Warning Lights On - Gauges Erratic?
The battery light came on in my '04 F150 a couple of days ago. Terminals were in need of cleaning, so I took care of that. The next day after driving 50 miles to and from work, the battery light came on again, along with the ABS & Brake light started flashing. After shutting the truck off, it would not start.
Three days later, I have now installed a brand new alternator and battery, only to have the same symptoms pop up about one minute after start up. The warning lights are now accompanied by the passenger airbag light and all engine instruments needle sweep back and forth. Dash lights go dim and bright intermittently as RPM varies.
Do I need old fault codes cleared or is this a PCM issue?
Ford F-150 - 1997-2003 :: Instrument Cluster Gauge Lights Not Showing And Alternator Is Not Consistently Charging
I have a 1997 Ford Expedition, 5.4. My research indicates that fuses 2. 19. 29 are associated with the instrument cluster (IC), could you identify their specific function in relation to the IC? My IC gauge lights are not showing and my alternator is not consistently charging. The blinkers, battery, oil, brake, and ABS indicator lights are showing in start. Regarding the alternator, my research indicates that a failing alt light on the IC may cause the no charging condition? As a note, I have a brand new battery, brand new alternator, brand new 3 pin wiring harness. Also, when the alternator is not charging and I connect the a jumper from the exciter wire directly to the pos battery terminal, the charging starts.
View 9 RepliesFord 7.3L Power Stroke (1999-2003) :: Dashboard Warning Light For Alternator / Battery Occasionally Light Up While Driving
The past few weeks the dashboard warning light for my alternator/battery will occasionally light up while driving down the road. Whenever it does, my plug in voltage meter shows a healthy 14.x reading. It usually goes out after a few seconds, but will stay lit up for as much as thirty seconds. So other than voltage being too high or too low, what else will cause the dash trouble light to illuminate?
