Vehicle
Holden Cruize, 2009, F18D Engine
Symptom:
The vehicle shows a check engine light on the dash board, the fault code is p2096 the description is post catalyst fuel trim system low limit.
the driving technique to make the symptom reoccur is warm up the vehicle so both o2 sensors front and rear are ready to send signal back to PCM, drive for 5 mins and drive to 80 kmh and back off the accelerator this will see that the o2 sensor both reach 0.00v when the vehicle is stopped and back to idle the front o2 sensor will start to cycle again, the rear o2 sensor will be at 0.12v – 0.18v and steady generally the voltage will take a while to rise, back to normal of 0.76v which is in the normal range of operation.
after this the check engine light will not come on the dash board but the fault code p2096 will be set in the PCM, during the test drive if you clear and carry out the same road test it will also be set again as the issue is still the same. this method of testing was the only way I could reproduce the fault time and time again.
Vehicle
Holden Cruize, 2009, F18D Engine
Symptom:
The vehicle did not start since towed in, we had a look at the fault codes and identified the fault as a body control Module (BCM) fault
Vehicle
Volkswagon Golf 1KZ 2008, TSI BLG engine
Symptom:
Engine light on, and vehicle responsiveness a little slow
The Vehicle had been bought to the workshop to find out why the engine light is coming on, a quick scan revealed a 08213 error also known as p2105 fault intake manifold flap position sensor fault improbable.
Vehicle
Holden Astra, AH, 1.8l Z18XER
Symptom:
Engine light on, and stalling sometimes when stopping at traffic lights
The Vehicle had been bought to the workshop to find out why the engine light is coming on, a quick scan revealed a p2120 error.
After trawling the internet for hours looking for a specification of oil for Volkswagen DSG gearboxs, instead i found Mercedes benz oil chart, which shows all the specifications Mercedes recommend for what particular frame chassis. having owning an S -class Mercedes it poked my interest to see if was using the minimum or maximum specification that we currently use in the workshop today, i did find that even in a slightly older vehicle with our Sydney climate i could use a slightly heavier oil viscosity, having using at least a 229.3 spec oil, i still wasn’t happy with amount of zero weight oils such as 0w-40 in my opinion this is far to thin for Sydney’s climate hence we have been suing 5w40’s and 10w40’s mostly.
So just to be sure next time you need to find the oil specifications for any lubricant, such as engine oil, auto oil or coolant, be sure to open up the pdf and check what specifications you must use as a minimum, check the viscosity chart for temperature of your climate and also remember that an engine that has done 20,000 kms is totally different to and engine that has done 200,000 kms. Apart from all the above information the only other thing as a repairer we can tell you is to listen with your ears and notice what sounds the engine makes this will help in giving you the best outcome.

Vehicle
Holden Commodore VE SS V8, Series 1
Symptom:
The alternator light comes on on dash board that warns you that the alternator is not charging, The late model vehicles have ECU controlled, charging circuits and no longer just use the battery for sensing, the alternators are pulse width controlled by the ECU for charge rates from the alternator. When the alternator lights comes on you now have to ask your self is the battery not being charged due to a faulty alternator or is the Engine ECU not sending a signal, or worse both,

We started to test spark coming out from the igntion coil at the distributor and no spark, we tested the coil had power and that the efi relay and fuse was ok, then it became a matter of using a scope to test that the crank sensors in the distributors where working, we scoped and found that all was good and that engine ecu located behind the glove box was receiving the signals, we then found that the ignitor next to the coil controls spark to the coil and the injector power, so we checked that there was power to the injectors was was present we then used a wiring diagram to pin point output the ignitor grin the ignition coil, the reading where not a normal output that you would expect so of course we blamed the engine computer for being silly and not doing what we wanted off course just blaming a part will get you into trouble if you don’t first test all the power and ground circuits to the engine ecu, so we did that and still nothing , we replaced the engine computer and still the same thing, by this stage I was shaking my head thinking I have really missed somthing, so it was back to scoping all the componentry again to check that I hadn’t missed something buy mistake
Have you ever done the job on the car and realised where do i find the information to do the simple reset for a light?
How the TBELT light works
