Re: Low Compression bent rod? WPS

Well it seems we may still get an answer on this as I have been asked to continue to try and find the cause first so I am gonna get it running again and warm it up which will give me the chance to give it a thorough wash and hopefully see if anything leaks under pressure when its hot and then I will...

Re: Low Compression bent rod? WPS

Hi Steve, thanks for taking the time to put that together, I did try a similar thing last night but with nowhere near the detail of yours and they were both the same colour which didn't help but I guess that comes with practice. I got the chance to question the driver myself today and it turns out o...

Re: Low Compression bent rod? WPS

I decided at this point I needed to access and remove injector 6 and upon removing the rocker cover a visual inspection of the cam/valve gear revealed nothing and there was still no signs of oil contamination. After confirming the compression was low with a manual gauge I done an in cylinder with th...

Re: Low Compression bent rod? WPS

Due to the even pulses in the fuel rail pressure I was happy enough the injectors weren't the cause of the hydro-lock added to it being the rear most cylinder and with the engine angled slightly backwards points me to something entering via the intake. Normally I would suspect the Egr cooler dumping...

Re: Low Compression bent rod? WPS

The next step was to run the engine to show the Cam signal against an injector current to ID the offending cylinder, I used cylinder 2 as it was the easiest to get an amp clamp round at the ecu because the injectors are fitted under the rocker cover which is a mission to get off due to the air clean...

Low Compression bent rod? WPS

Having recently purchased a WPS500 I like to use it where possible even when I have a fair idea whats wrong to aid learning whats good and bad for when I have no idea. So I thought I'd share what I'd taken in case it may help others and also if I may be missing something which is highly likely being...

Re: 4425 Advanced on its way (hopefully)

Well a bit of an update, after nearly 6 months of having the Pico I wonder how I ever managed without it, it generally gets used most days and I have learned a lot, the support from Pico has been fantastic and far exceeds any I have had from suppliers of any other diagnostic equipment I own. I have ...

Re: Mercedes B class AMG line diesel auto

I know for sure on much bigger mercs the additional batteries are for a RPS redundant power supply which is a back up for the electric power steering in case the main power supply goes down whilst driving.

Re: New PicoScope Automotive Software 6.13.17.4271

I must say the initial freezing issues seem to have passed so likely due to the laptop I was using although there does seem to be a delay with the play and stop capture so its easy to lose the capture as I have done a few times. It would be nice to know if anyone else has the same issue or if that's...

Re: Hello!

Hi Carl Welcome to Pico, I am also a HGV mechanic and have only had the Pico for a few months but I wouldn't be without it now, its worth remembering that people may have the waveforms you need saved on the computer but not yet uploaded them so its worth posting if there is something specific you ar...
