Hi all
looking for some advice - I have read all of the threads on this I can find and cannot figure out the problem. I have also posted this on the TDIclub MK6 and MK5 forums.

I have a 2011 JSW and am getting P0087 error codes combined with the flashing glowplug symbol and then the check engine warning lamp and the car goes into limp home mode. They can come on every mile or nothing for 500 miles. In between resetting the codes the car runs perfectly until it starts setting codes again. This has been happening for the last 2500 miles. First thing I did was check for filings in the pump fuel metering valve but its totally clean.

I have read through all of the forum posts on similar problems but very few people post their final solutions. The only post that seems to have done so found that replacing the fuel metering valve on the pump worked for them. I have replaced the filter and checked the fuel lines are unkinked and free flowing. I have the ross tech cable and VCDS and my lift and aux pumps seem to be running at the right pressures so I replaced the fuel metering valve - no metal particles visible anywhere. The replacement has not helped so I need some outside help because I just hate throwing parts at a problem! I have messaged 2 micron about his technique for cleaning the fuel pressure regulator on the rail but I cant find any details to the technique. If anyone has had the same problem and solved it can you tell me what the solution is because i am banging my head against the wall on this one - I have also been through all of the posts on the MK 5 forum too and lots of people have posted the same - or similar - problems but no solutions seem to be posted - the threads just stop - any help greatly appreciated.

EOBD II Error Code: P0087

Fault Location:
Fuel Rail/System Pressure - Too Low/Implausible Signal

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Power Loss.

Fuel pressure too low.
Fuel supply pipe blockage.
Fuel pressure sensor harness open circuit or shorted.
Fuel pressure sensor harness electrical circuit poor connection.
Blocked fuel filter.
Visual Inspection of Hardware (Camshaft, Cam Follower, etc).
Mechanical Deficiency of Hardware (worn or missing parts) .

Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Check Measuring Value Blocks (MVB) for Fuel Pressure.
Fuel trim activity 0.90 - 1.15.
Output value rail pressure controller > 2 MPa.
Difference between target and actual pressure > -16.38 bar.

Check for bent/squeezed Fuel Lines.
Check Low Fuel Pressure System for Leaks.
Check Fuel Filter & Filter in Fuel Pump.
Check the Fuel Quantity supplied by the Fuel Pump (G6).
Visual Inspection of Hardware (Camshaft, Cam Follower, etc).

Special Notes:
When found in 2.0l TFSI:
Check Fuel Pressure.
Check Technical Service Bulletin (TSB) 2027458/01-11-19 (North American Region (NAR)), for an improved Fuel Pressure Sensor (G410).
Check Technical Service Bulletin (TSB) 2015153/15-11-03 (North American Region (NAR)), for a worn Intake Cam Shaft (superseded Technical Service Bulletin (TSB) 15-10-02, 15-11-01 and 15-11-02).
Check Technical Product Information (TPI) 2014143 (Rest of World (RoW)), for a worn Intake Camshaft.
Check Technical Product Information (TPI) 2014909 (Rest of World (RoW)), for a worn Intake Camshaft. This Technical Product Information (TPI) does NOT list in the Audi A6 (4F) BPJ Engine even though it is effected as well, so check for a worn Intake Camshaft of these too!
When found on 2009 Audi 3.2 FSI AVS Engines, if Diagnostic Trouble Code (DTC) 000022/P0016 is flagged, please see Technical Service Bulletin (TSB) 15-09-04.

When found on Audi Common Rail V6, V8 and V12 TDI engines, please see Technical Product Information (TPI) 2020693. After mechanical all repairs are made Fuel Pressure Regulator Valve (N276) may need to be adapted and the EDC may need to be flash updated on the Audi Dealer level.

Tech Notes:
There is a service bulletin for the following Volkswagen vehicles:
Volkswagen Eos 2006-2007.
Volkswagen GTI 2006-2007.
Volkswagen Jetta 2005-2007.

Volkswagen Passat Wagon 2006-2007.
Volkswagen Factory Service Bulletin OBDII Code P0087

When is the code detected?:
The Engine Control Module (ECM) has determined that the fuel rail pressure is too low for a specific engine RPM.
