Re: Vauxhall Corsa 1.4 2010

Well done curing this one. At least you can put it down to experience and you have had time to practice with the scope. It sounds like you need to do yourself a favour though and find yourself a workplace where your tenacity and passion for learning are rewarded and encouraged, not hampered. Find th...

Persistance mode in PS7 Automotive

Good afternoon everyone, I hope you've had a great weekend. I have just finished watching the video from the last newsletter where Steve demonstrates CAN decoding on the Ford Focus with cracked solder joints on the instrument cluster. When he carried out the 60 Ohm resistor test with the resistance ...

Re: What else could it be?

Well done Steve, what a great post. It proves persistence pays off! I have seen poor quality fuel cause similar damage to injector nozzles before on 4 cylinder diesels but never on the V6's. When I have seen such damage on the past it has exhibited different symptoms to this too, namely a soft misfi...

Re: Graphing Serial data

Hi Steve and team, That is a very interesting guide and it seems it is the only way that you can corrolate signals from encoded sensors such as SENT against traditional analogue and PWM signals to make sense of a cars behaviour. I can see how much work you have put into making this possible using th...

Re: 2016 Audi A6 P0087

Hi Mike, unfortunately it is pretty much always the case that these low pressure issues are caused by mechanical damage on the pump sending swarf into other components (normally caused by a historic mis-fuel or years of poor quality fuel), usually starting with the pressure regulating valve on the e...

Re: Making a return

Hi Steve, yes I’ve seen the VAS NVH kit but unfortunately we do not have one, one of our other branches has one we can borrow though, I might borrow it sometime to experiment with! I am currently running Pico6 in one PC and 7 on another to see the different layouts and make a gradual transition. I w...

Making a return

Hi everyone, I have been part of this forum before but haven't been on for a couple of years. I have finally had the means to purchase a 4425a after making do with our manufacturer supplied scopes for years. I also have a 2000 lab scope which is great but I've been limited by the bandwidth and volta...

Re: Transporter 2.0TDI CR Outs Temp sensitive

Hi, just a thought, but have you checked the cylinder compressions and cylinder leakage? The injector quantity compensation looks a bit off for a new set of injectors (you did code the new injectors to the ECU didn't you?). A mechanical (compression) issue would also make sense regarding the air mas...
