Hello!
I tried to search in the forums for a thread but could not find any relevant for my issue
I also have a couple of questions regarding my troubleshooting

According to RossTech Wiki P0087 there are several solutions for this faultcode.
The HPFP was replaced last month, and the fuelfilter was replaced yesterday.
The old HPFP pump was inspected for metal shavings, nothing to be found.
I can read from the rosstech wiki that
"When found in Audi Common Rail V6, V8 and V12 TDI engines, please see TPI 2020693 for Contaminated fuel found in fuel system concerns. After mechanical all repairs are made N276 may need to be adapted and the EDC may need to be flash updated on the Audi Dealer level. When a dealer level update applies SVM code 01A036 is used."
Im not sure if the new pump was adapted, nor am I sure if this needs to be done.
I have tried to log IDE00188 -- Fuel high pressure; actual value and IDE00201 -- High fuel pressure; specified value, but as you can see in the faultcode in the full scan, the actual value differences aprox 200bar from the specified value at the time it throws the fault code.

Is there any way I can use this method belowto check for pressure leak in the fuel system, or is this for gasoline cars only? I tried to follow those steps but the actual fuel pressure value is not moving when the engine is off (and ignition on)
Is there also any way to log or test the lift pump inside the dieseltank?

Last question is regarding the VC scope, im not so familiar with that.
Why wont the green line scale like the red one? I notice that it says "100" top left corner, but I cant change that. I have also tried to type in dozens of different values in the "vertical scale min/max" bottom right corner, but its only the red line that changes. What am I doing wrong?

Thanks! Now I got it right.
But now a new problem accured;
Everytime it exceeds a certain value the graph goes to zero in the graph window.
Why? is it because the values recieves a letter (e+) when exceeding 1000bar?
Its impossible to log the acceleration when it suddently drops to the floor during thepull

That is a distinct possibility. It would not be completely shocked if VC-Scope did not handle a dynamic data format change gracefully.

In that case, the most expedient solution might be to log the data and graph it in Excel.

"When found in Audi Common Rail V6, V8 and V12 TDI engines, please see TPI 2020693 for Contaminated fuel found in fuel system concerns. After mechanical all repairs are made N276 may need to be adapted and the EDC may need to be flash updated on the Audi Dealer level. When a dealer level update applies SVM code 01A036 is used."

Im not sure if the new pump was adapted, nor am I sure if this needs to be done.

I don't believe that TPI applies. No doubt, there appear to have been 2 flash updates over the years for that 4L2 910 401 B EDC and SVM code 01A183 would likely bump it from SWL 0001 to 0004 ... but the 2042993 TPI I located was glow plug specific. I don't think getting a dealer level flash is going to help in this case.


Is there any way I can use this method belowto check for pressure leak in the fuel system, or is this for gasoline cars only? I tried to follow those steps but the actual fuel pressure value is not moving when the engine is off (and ignition on)

Is there also any way to log or test the lift pump inside the dieseltank?

The procedure in the video is gasoline specific but you can verify that injectors (or high side components) aren't stuck wide open by shutting it off and making sure the fuel pressure doesn't drop off immediately.

You can run this procedure:

http://wiki.ross-tech.com/wiki/index.php/Fuel_Pump_Basic_Settings_for_PD,_PPD,_and_CR_TDI_Engines

Although it is intended for fuel filter replacement rather than pump testing that will operate the in-tank (and any in-line) pumps.

Thanks for the reply. As mentioned the actual fuel pressure value is not moving when the engine is off and ignition on, its standing on defualt 2500hpa.
I did some test runs last night, and the ecu is asking for 2000bar but it only measures 1800 on actual pressure.
The car was previously tuned (chip tune) but later overwritten to stock, but Im starting to think that there is a problem with that chiptuning.
I have read somewhere that the 204hp V6 HPFH delivers 2000bar and the 245 V6 HPFP delivers 1800 bar, so there might be something worth checking out

Newest flash update (0004) did not help, and that kills my theori about a bad chip file.
Next up is to find out if the pressure regulator valve is somehow leaking or is faulty.
Pressure valve was changed 2 years ago

Have you measured actual fuel PSI/Volume?

Mechanical issues must be qualified with actual test equipment to qualify block data as reported or basic isolated tests.

Have you tried an isolation plug at each injector path on rail & to see if rail PSI is achieved during cranking in blocks or mechanical gauge?


Did you know a fuel rail injection isolation cap can be made with an old line from junk yard cheap or purchased from any quality injection rebuild outfit for Bosch?


This should be in any serious EU diesel shop tool box!
