Timing belt kit CT1134K1/WP1/WP2 for Audi, Seat, Skoda and VW. Various 2.0 TDI Common Rail models, 1st generation

Problem

The supplied V56340 tensioning pulley differs visually from the pulley installed in the vehicle and seems as though it cannot be correctly tensioned.








Cause

In the original equipment, the pulley design as in Fig. 1 is installed. A slightly modified tensioning pulley is supplied for the aftermarket – see Fig. 2.










Solution


To set the tension correctly, the new design first has to be compressed as far as possible using the new nut on the stud bolt such that the “stirrup” fitted on the reverse of the baseplate can slide past the casting (maximum load stop): see Fig. 3.

Fault in the catalytic converter inlet sensor in the Suzuki Ignis II


On this occasion, we are going to repair a common fault that affects the Suzuki Ignis II 1.3 (M13A), manufactured from 2003.
SYMPTOMS

The symptoms shown in this incident are:

- Engine failure lamp (MIL) on

- On reading the fault codes in the engine control module (ECM) with the diagnostic tool, we see code P0420 is recorded (Catalyst system efficiency below threshold on bank 1).


CAUSE

The cause of this anomaly is due to a fault in the inlet sensor (sensor 1) of the catalytic converter.



REMEDY

The repair procedure for this fault is to measure the temperature with a thermometer at the inlet to the catalytic converter and to take another measurement at the outlet, and check that the inlet temperature is lower than the outlet temperature. If this is the case, directly replace the converter gas inlet sensor 1, because, as we say in this newsletter, it is a common fault and this solution is not always correct.

To assure yourself that the incident has been resolved, check that the exhaust gas system is operating correctly by means of a road test and the deletion of all the engine control module (ECM) fault codes.

Hybrid Technology in Honda Civic IMA


The Civic Integrated Motor Assist (IMA) Hybrid System is based on an electric motor mounted between the engine and the transmission. This motor assists with extra torque which considerably reduces the vehicle’s pollution levels.


The Civic Hybrid Technology recovers and transforms the energy that is lost during deceleration and braking. This technology stores the electric power in order to assist the engine when electric power is required.


It should be noted that the engine uses two ignition coils per cylinder, as well as the variable distribution system VTEC.

The electric motor works at 158V 3-phase AC, and it is used to start the engine and also as a generator that charges the battery. That is to say, the electric motor acts as a starter motor and an alternator.

The 158V battery is formed by 20 modules of 6 cells, each one connected in series. Each cells voltage is 1.32V.


In contrast to its competitor the Toyota Prius, the Honda Civic cannot launch from standstill using only the electric motor. The use of the engine is needed to launch the car.

For the Civic to drive on electric power alone,
the vehicle speed needs to be between 20 km/h and 50 km/h (12 mph and 31 mph). In this case the system will decide if it requires assistance from the engine in accordance with feedback from the accelerator pedal.

In contrast to the Toyota Prius, the petrol engine does not stop turning while the car is driving.

The system is additionally provided with a 12 volt battery which is recharged by a converter located next to the inverter. The converter-inverter assembly is cooled by an electric fan in order to avoid overheating problems. In some models there is an additional alternator to provide the charging for this battery in the case of a failure.


ELECTRIC MOTOR ASSISTANCE

During the startup, the engine is started by the electric motor. From then on, depending on the battery charge condition and the torque delivery need, this electric motor assists the engine to a greater or lesser extent.

It is under high load accelerations (e.g. in ascending slopes) when the electric motor delivers maximum assistance.
When driving at constant speed, the assistance level that the electric motor provides the engine depends on the battery charge condition.

When driving at high speed and with a low charged battery, the electric motor recharges the battery instead of assisting it.

During deceleration, the electric power is used to recharge the battery depending on its condition.

ATTENTION!

In case you have to carry out maintenance or repair work on the high-voltage circuit system, it is very important to turn the main battery switch on and place it to the “off” position. In this way, we disconnect the high voltage supply over the complete circuit.

 All safety precautions set out by the manufacturer should be referred to before conducting any repair work on this vehicle.

Engine malfunctioning without recording of fault codes

On this occasion, we are going to repair a fault that affects the BMW 3 series with M57 and M57N diesel engine.

SYMPTOMS



The engine malfunctions during different operating phases, for example, while accelerating, on starting the engine from cold and/or when travelling at a constant speed at low rpm.

After carrying out a diagnostic reading, no fault code can be seen recorded relating to the engine problems.

One of the causes of this anomaly is that there is a deterioration in the fuel rail sensor connector or in the sensor wiring.


CHECKS

To carry out a repair, check to see if a fault code has been recorded with a diagnostic tool. Then carry out an injector correction reading to verify that one of the injectors has an incorrect value and rule out possible problems. At this point, check that on moving the pressure sensor connector by hand, the engine provides an easily perceptible positive response.

After the above results, the connection problem is shown to be in the fuel rail pressure sensor. To resolve this incident, the fuel rail pressure sensor wiring should be removed and replaced with a specific kit from the manufacturer.

Park assist

Park assist systems are designed to help the driver during parking manoeuvres. The most used systems are those with ultrasonic parking sensors or a rear camera.


Camera rear view






Ultrasonic parking system

This is based on the use of sensors installed in the bumpers distributed strategically to cover a wide area. These sensors are mounted on the rear bumper and optionally on the front and are controlled by a control unit. 

The system is activated automatically on engaging reverse gear, the sensors are activated and emit an ultrasonic pulse that travels through the air. If there is an obstacle, the ultrasonic pulse will rebound from it and return to the sensor which will detect the pulse and inform the control unit. The control unit makes the calculation of the distance to the obstacle based on the time elapsed between the emission and the reception of the pulse. The maximum detection distance is approximately 0.8 to 1 metre.


The control unit emits an acoustic warning so that the driver knows the distance of the obstacle. These warnings are transmitted through independent loudspeakers or through the vehicle's audio system. As the vehicle nears an obstacle, the repeat rate of the audible warning increases. When the object is less than 30 centimetres from the centre of the vehicle’s bumper, the acoustic warning will sound continuously. 

If the driver does not wish to use park assist, there is a switch for enabling or disabling the ultrasonic parking system. This is located in the cabin, generally in the centre of the dashboard or in the central console.


Rear camera system
This system uses a small video camera and a screen for displaying the images. 






The rear camera is located at the rear of the vehicle and strategically focused to assist parking. In the same way as the ultrasonic parking system, it is activated automatically on engaging reverse gear. 
This system uses a control unit which manages the system, which, if the vehicle also has the ultrasonic parking system installed, one unit may be used for both systems. 

The transmitted images are displayed on the video screen. This screen may be independent or may be shared with other systems, such as the navigation system. Lines are shown in the screen that determine fixed distances for assisting the driver when parking. The lines are green, yellow and red. The red line measures the distance between the rear bumper and 30 cm behind it, and the yellow line measures between 30 cm and 60 cm behind the bumper.

Parking space

measurement systems


This system measures the size of a parking space in comparison with the length of the vehicle. This system uses ultrasonic parking sensors that are located on the sides of the vehicle.

The measuring of an available space is activated when the system is selected with the switch, the speed of the vehicle is less than 20 km/h and the direction indicator of the measuring side is activated.


The screen will show different images depending on whether the space is ample for parking the vehicle, is just sufficient or is too small. 
The available parking space measurement system is deactivated in the following cases: 
• When the ignition is turned off. 
• When the reverse gear is engaged. 
• When the speed of the vehicle exceeds 70 km/h for more than one minute.
• 10 seconds after turning off the direction indicator. 
• When the electrical connection for the tow hitch is connected.
• On pressing the available space measurement switch for deactivating the system.

Automatic parking systems 

This assist system is an active function that aids the execution of the manoeuvres when reverse parking. The automatic parking system is capable of automatically steering the vehicle for parking. The only thing that the driver has to do in this case is operate the accelerator, clutch and brake pedals. Furthermore, the driver can retake control of the steering at any time he or she wishes to do so and cancel the automatic parking manoeuvre.

This system accurately measures, with the help of side ultrasonic sensors, the parking spaces and then carries out the manoeuvres to park the car in the space, without the driver having to use the steering wheel.


Ford is currently developing a fully assisted automatic parking system. This new system controls the steering, gear selection and forward and reverse movements for parking. Therefore, the driver can be inside or outside the vehicle during the parking manoeuvre.



This system requires a vehicle to have an automatic gearbox, using a gearbox called Powershift, which is capable of electronically controlling the forward and reverse gear changes without the physical intervention of the driver.
