vw beetle ASC light

A few weeks ago we had a VW beetle 1.6 petrol come into the workshop. It had a couple of issues, the engine management light was on and so was the traction control light but the ABS light was off.  After scanning with the FCAR F3W we ascertained the fault with the traction control was with the ,lateral acceleration sensor, and the engine fault was due to a secondary air system malfunction.

We quickly sorted the engine fault, it was just the vacuum pipe going to the valve on the manifold, a quick and easy fix. The traction fault was next,

we had looked at the live data from the sensor and decided the problem was either the unit itself or the wiring, the values were way off what they were supposed to be, according to Ross Tech the correct settings should be +- 1.5 ms , this one was reading +7.8

Now this is where things got strange, after removing the plug to the sensor (the acceleration sensor is easy enough to get to, it is mounted to the steering column, you need to remove the panel above the pedals to access the sensor) and checking and cleaning the wiring, once it was all assembled again once we switched on the ignition, the ABS was on with the stability light, we rescanned the module but now the module coding had disappeared!

Of course as we were not interested in coding or doing any other tests than reading the faults and viewing the live data, this was a bomb from out of the blue. We did not have the original soft coding and as this was a MK 20 system so there was no info to figure out what the coding was. After a lot of searching I finally found a site that had soft coding for the MK20 module. After entering 40168 to allow the login we then matched the ECU type and  information with the list below and we were able to successfully recode the module. Here is a list of the modules and their coding:
A very useful piece of information.

If you have a problem with your Fiat or Alfa Romeo car or Fiat Van, then you really should look at the Multiecuscan software for Windows. It is an affordable way for the home mechanic, small garage or even a large garage branching out into multi marque service and repair to access near dealer level coverage on Fiat and Alfa Romeo vehicles

Multiecuscan diagnostic software for Italian vehicles is also ideal for the  garages that specialise in servicing and repair of Fiat and Alfa Romeo vehicles

Using the free version of the software and a kkl cable with built in pin switching, you can access a lot more than basic reading and clearing engine faults. It works on older cars too  by using the 3 pin to 16 pin OBD2 adaptor, it can go back as far as the early nineties.

New era Fiat and Alfa Romeo

If you have or maintain the new Fiat or Alfa Romeo vehicles, then the registered kit is for you. With it you can read and clear codes, perform proxy alignments, reset service indicator lights, match injectors, in fact pretty much all the garage would be able to do without paying through the nose. Examples of the coverage include. Fiat 500 airbag reset, oil service light reset on all late model Fiat and Alfa Romeo vehicles including the Fiat commercials. Also as manufacturers are pooling their resources and using engines or whole vehicles rebadged ( the new Opel combo springs to mind) this kit will work equally as well on these rebadged Fiat vehicles

Scantool-Direct are an appointed distributor for the Multiecuscan software and have a full compliment of suitable tools to use with the software, from a basic kkl cable to the all in one multiplexed professional system, we can supply a kit that is suited to your needs whether it be home based occasional use or specialist professional use.
