What ihappens if i Press the asr button on a 2001 beetle


ASR stands for "Anti-slip Regulator", which is the traction control on MkIV and MkV Jettas. It's a simple system that cuts torque to a wheel that is slipping, to give it a chance to stop turning and possibly get a better grip on the road surface. The ASR does not activate above speeds of 20 MPH, and therefore is really only intended to assist in highly slippery surfaces such as hydroplaning water (the height at which this affects the car is largely determined by the ability of your tire to guide the water underneath it through channels to get it out of the way) or snow. ASR doesn't help on ice -- nothing helps on ice except studded tires or chains.

ASR replaced the older ESP system, and is vastly inferior to the Haldex 4MOTION system found on limited VW models.

My 12v haldex snow plow pump it draws so much power it kills the truck it goes up very slow and labored it wont turn l or r it is wired correctly been on truck 3 years ,problem just started


Dear Lawnie,
If you have a plow, that tells me you live where it i cold.
If so, perhaps you have salt used on roads and highways.
That salt can damage your plow, as well as your vehicle.
I think you may have salt or rust damage that is slowing down your pump.
If not, I would suspect one or more of your joints is freezing up.
Unfortunately, I think your plow may not have nuts & bolts to take it all apart and check each and every joint.
Many parts are probably welded together.
See if you can isolate the "stiff" joint or the pump itself for replacement.
God bless your efforts.

How to reset maintanence light


You need an OBDII scanner that will find the code and the option to reset the code. If the code (meaning maintenance light) comes back on then you need to get it fixed. AWD cars/crossovers/etch. Have a TON of electronics and extra components like electronic locking differentials or mechanical (nickname is "diff" ) diffs
. On the Outback the system is on all the time, and it has a Haldex differential that sends more power to the wheels with grip. There are a ton of things that can go wrong with a complex system.... but the main cause is electronic in nature. Also, simple things like replacing 2 tires and having the other two nearly bald will cues the wheels to rotate at slightly different speeds. The system can't handle that friction and stress for long and you can blow the AWD system mechanically.. All tires must be replaced at the same time or very, very nearly the same time. Go to AutoZone and they will check that light for you for free, and may even reset it for free or nearly free low-bucks. Good Luck. The Outback is a great car and will last a long time if you take care of her! -Chris

01324 error message J492 4WD ECU or something ?? got problem with ESP lights on both dash & switch by gear stick, had code read as 01324 with error message J492 "4WD ECU" or something like...


Fault 01324 - Control Module for All Wheel Drive (J492)

Did you clear the codes? And if so does the same one (error communicating with haldex controller) keep coming back? Most likely that you need a new controller.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

When accelerating , reaches about 4000rpm the ESP light starts flashing


Here are a couple of resources that have dealt with similar problems as yours. I hope they help.

Audi Forum Solution 1

Audi Forum Solution 2 This one scroll down most of the page to see a simple diagnostic test you can do in a parking lot.
Audi Forum Solution 3 Maybe your best solution here.

There are some easy solutions but some that require replacement of parts. But you should feel confident on what parts need replacing after reading those three solutions. It sounds like your Haldex control unit is locking up when it shouldnt be. Appears to be a common problem.

Good Luck

The all wheel drive doesnt work only the front tires spin in the snow


The 08 Vues AWD system is very different than from previous models. The new Vues system is more like the technology on the Outlook. I' don't know detail on the hardware, but from a function standpoint there are two big differences:

1)The system is PREDICTIVE, not reactive. It does not wait for wheel-slip to make it engage. The system monitors throttle position, steering angle ect. and re-directs torque before wheel spin occurs.

2) The old system sent extra torque to the wheels that were slipping to boost traction. The new system sends power to the wheels that are gripping.

The result is a better, smoother system that will do a better job of keeping the Vue from getting stuck.

The old system was a single gerotor type AWD system. Essentially, a gerotor AWD system uses differences in rotating speed to spin a pump and apply pressure to clutchs. The single gerotor system used in the Vue essentially engaged and disengaged the rear axle when a differences in rotating speed occurred between the drive shaft and rear differential (indicating the front wheels were spinning faster the rears). From here on out, power goes into an open differential and was distributed accordingly (i.e. not very well).

GM also uses a twin gerotor system in the form of Versatrak. This operation in much the same manner, using a difference in rotating speed to spin up a pump and apply pressure to clutches, except the Versatrak system has a pump for each output axle. This allows the rear differential to act of each rear axle much in the way a limited slip differential does, better managing torque distribution.

The new system used in the Vue (as well as the Outlook, Acadia, and Enclave) is controlled by a microprocessor and operates by means of an electromagnetic clutch. It is very similar to the Haldex system marketed by Haldex Traction AB. The main difference being that Haldex still uses hydraulic pressure to apply the clutches, while the electromagnetic system used by GM (which I believe is developed by Borg Warner) uses electromagnetic force to apply the clutches. The operating principles are the same though. The new GM system is well integrated with stability control, traction control, and ABS. The system actively monitors vehicle dynamics and driver input to determine when to being engaging AWD before it is actually needed. With the ability to manipulate power delivery using AWD and stability control (by selectively applying brakes at each individual corner), the new Vue is very robust in terms of torque management. For all you folks in the snow belt, it should be dynamite in slippery conditions!

Hope this helps answer your question. Good luck and be safe on the snow.
