LAMBORGHINI GALLARDO AND MURCIELAGO ERROR CODES

For those fortunate enough to own a Lamborghini Gallardo or Murcielago, we'll include a list of ODBII generated fault codes to help with diagnosing your vehicle yourself. If you are unsure of how to obtain the ODBII codes, please comment below and we'll look at making a short Youtube video or blog post to provide some guidance.

VW - AUDI INFOTAINMENT SYSTEMS VULNERABLE

Vulnerabilities have been successfully discovered by Computest in a 2015 Volkswagen Golf GTE and a 2015 Audi A3 Sportback e-tron. Both cars are manufactured by Volkswagen Audi Group (VAG).

An insecure software process exposed by the Wi-Fi interface used by the cars Harman In-Vehicle Infotainment (IVI) system allows unauthenticated access. Some further digging revealed that it was also possible to access the IVI’s Control Area Network (CAN) bus.

This meant that:

"Under certain conditions attackers could listen in to conversations the driver is conducting via a car kit, turn the microphone on and off, as well as gaining access to the complete address book and the conversation history."

And:

"There is the possibility of discovering through the navigation system precisely where the driver has been, and to follow the car live wherever it is at any given time."

The car uses a different, high-speed CAN bus for vehicle-critical communication such as steering, door unlocking, park assist, and – yes – braking.

That high-speed CAN bus is precisely one component away from the compromised IVI CAN bus: the two are separated by a CAN bus gateway that acts as a firewall between the two.

It’s here that the researchers stopped in order to avoid breaking the law. The researchers reported their findings to VAG, which seems to have taken the issue seriously enough to invite them to come to its HQ in Germany to explain them.

The company later said it had patched the flaws that allowed access, although of course that would only fix new cars made from the point that firmware image became available.

HOW TO DIAGNOSE BAD IGNITION COIL

There are a couple of ways to check whether or not your car is misfiring (it may sound like it's running on less cylinders or very rough, a tractor or generally a noticable loss in power). While the ignition coil may not be the cause of the problem, it's definitely worth checking as it's fairly straightforward. The first method is simply using a ODB scan tool such as Carly or ODBII and read for fault codes related to misfiring/spark/ignition issues in a specific cylinder. A more traditional approach is to unplug the ignition coil while the car is running, if the car runs the same with the ignition coil unplugged then you know that there may be an issue with that cylinder and you can proceed to check the spark plug, ignition coil and wiring. If unplugging the first ignition coil and the behaviour of the car is worse then plug it back in and move to the next cylinder until you find the coil that is the culprit which means no changes after unplugging. As a test, you could use the ignition coil from a known good cylinder and replace the one in the bad cylinder to see if you can replicate the behaviour (the scan tool may also show the bad cylinder follows the coil). If this is possible then it is highly likely that the ignition coil is bad and requires replacement.

FACTORY COILOVER ADJUSTMENT FERRARI 360 - 430

The Ferrari 360/430 platforms came standard from factory with coilover suspension which allows for ride height adjustment in true racing fashion! Those who opt to lower their car (most enthusiasts seem to for better looks and lower center of gravity) can do so with a bit of know how and also the right tools. Note that you will most likely need to take the car to a workshop to have a professional alignment done once lowered. We provide a rough guide below on how to adjust the factory coilover for those who like a bit of DIY.

For a standard 360 the height is 125.2mm at the front and 146.8mm at the rear.

Front: Ahead of the front wheel there is a rubber drain tube. Measurement is just behind that tube on the aluminum frame. 

Rear: Below the curve of the lower air scoop.


Ferrari also suggests doing the measurements and alignment with a 70kg load in both the driver and passenger seat/footwell area to replicate the weight of an average person. 

In order to adjust the height, you will need to loosen the perches using a C-Spanner (can be purchased here) holding the spring in place, these are highlighted in red below. The upper perch is 90mm and the lower perch is 70mm - purchase the according tools on the website. 


Calculating vehicle drop is based upon the number of downward turns of the spring perch. Total body drop is affected by the Motion Ratio which is the ratio of shock travel versus wheel travel. It is equal to the Shock Travel (in inches) per 1 inch of Wheel Travel. Motion Ratio is used to account for the different suspension geometries and the resultant mechanical leverage on the spring. In almost all cases, the Motion Ratio is less than 1.

One can generally calculate the Motion Ratio by simply dividing the shock travel by the wheel travel. Example if the shock travels 0.5 inches and the wheel travels 1 inches then the motion ratio would be 0.5/1 = 0.5.

To achieve a 1" drop, we can base the calculations on the MR value as 0.70, 12 turns will drop your vehicle 1" (25.45 mm/cm/1.5mm = 16.97 turns X 0.70 = 11.88 turns/cm).

The threads on the Ferrari shock body are pitched at approximately 1.5 mm which means that every turn of the ring should equate to a drop of 1.5 mm. This means that for every downward turn of the top spring perch nut with a motion ratio of 0.70, you would get about .084” of downward travel of the body.

Once you have completed lowering the car, tighten back up the spring perches and head on over to your alignment workshop which we mentioned earlier. 

Ferrari 360 Alignment Settings

Height (CS Spec)
110mm front
130mm rear

Castor 
6.3 degrees (fixed)

Toe
1.25mm front toe-in
1.5mm rear toe-in

Camber (CS Spec)
-1.28 degrees front 
-2.00 degrees rear

Camber is adjusted by inserting or removing shims between the bottom wishbone mountings and the chassis. Increasing the width of the shim pushes the lower wishbone outwards and thus the top of the wheel leans into the car more = more camber. Adjustment requires removal of the wheel, undoing the wishbone, inserting or removing shims, refit wishbone and wheel then lower the car and re-measure the camber.

FREE INTAKE MODIFICATION - GOLF MK7 / R / AUDI A3 / S3

We've noticed that the standard air intake for the Volkswagen MK7/R Golf and Audi A3/S3 models appear to come with some restrictions. While the manufacturer may have a legitimate reason to ensure these restrictions are in place (emissions, reliability) or otherwise, they are definitely robbing from the performance and induction noise. We'll explain below briefly how to remove these restrictions in an Audi A3/S3, however, this will also work across the turbo charged Volkswagen MK7 range.

1) Remove the screws holding on the front air induction box and intake

2) Use a hole saw + drill or dremel to cut out the plastic section blocking off airflow to the airbox

3) Remove the airbox cover, air filter and then finally the plastic grate sitting below the airbox, this will come out with a tug

4) Remove the grill trim sitting at the top of the Audi grill

5) Reassemble all parts and optionally replace panel filter with a high flow item from BMC/K&N. 

That's it, a few simple items to be removed in order to increase airflow to the air box. Combined with a high flow panel filter, we suspect that performance results will be similar to that of expensive 'cold air intake' systems on the market.
