Any more data yet Bjorn I have planed to do some tests on one of my daughters cars over christmas they both have vw with fsi engines I know the sensors and the regulator are easy to get to Going to restrict lp flow and monitor hp sensor just to see the affect this hp pump is different but id like to...

hi
Just a thought cant you do static timing using clock dial indicator and a graduated degree wheel on the crank

Thanks Andrew

Hi all think i agree with the toy bit a toy kite can show wind direction just as well as a wind sock but maybe not as much info on strength joking aside lets not ruin another interesting post worth looking at picos data logger acts like a graphing meter it will show a can signal if i remember rightl...

The only thing i would say is a bench scope or usb scope designed for electronics will work and for a few years i used one. I had various over the years stating with a tektronics that had plug in front ends depending on the work ie band width then moved on to dso but my hobby has always been electro...

Hi all

My quick down and dirty method is independent pressurised fuel supply (converted ac flush system which can deliver fuel from 20 psi to 100 psi if needed ) rules one out or in

So this is a zoom of the HP sensor


does not look very good compared to the diesels Ive looked at lately it looks like 1 of the pistons/diaphragms may be faulty

or I could be wrong as Im just musing

Hi Tronic

been following this thread and Ive got to say that's a very nice tool box especially the rigol scopes and is that a rigol signal generator as well very nice

Hi All I use one of these http://www.jyetech.com/Products/085/e085.php sine square triangle variable offset and voltage also supposed to be able to program custom wave forms such as possible crank sensor but not tried yet works well for things like lambda variable offset means you can sent the offse...

Thanks STC

Like the idea of using 2 pwm
have a diesel mondeo in on wednesday with a similar random intermittent fuel pressure problem think Ill order another pwm driver

Thanks andrew

Hi GDI Gas Direct Injection my suggestion to start would be a variable resister say 10K ohm connected instead of the pressure sensor set the resister so that you get a suitable fuel pressure on the scantool and see if you lose pressure if you still have the problem pressure sensor not likely at faul...
