Pretty well known issue already, but as of yesterday, VWoA has finally released their own T.B. about this. Basically says exactly what the Audi one said.
Technical Product Literature Transaction No.: 2015153/1
MIL ON, DTC P0087, P1093 or P2293 Stored in ECM Fault Memory Release date: Jun 29, 2007
Condition
15 07 04 June 29, 2007 2015153
MIL ON, DTC P0087, P1093 or P2293 Stored in ECM Fault Memory
MIL ON with the following DTCs may be stored in ECM fault memory:
DTC Description
P0087 Fuel Rail / System Pressure - Too Low
P1093 Fuel Trim 2, Bank 1 Malfunction
P2293 Fuel Pressure Regulator 2 Performance
Technical Background
Excessive wear of intake camshaft lobe that drives the high pressure fuel pump. The wear limits maximum pump piston lift, causing fuel rail pressure fluctuations.
The wear on the camshaft lobe can also lead to wear on the base of the high pressure fuel pump cam follower.
Production Solution
Increase surface hardening of camshaft lobe for the high pressure fuel pump
Improved intake camshafts have Part No. 06F109101B.
Service
• Remove the high pressure fuel pump and visually inspect:
1. Base surface of the cam follower -6- in contact with the camshaft lobe.
2. Tip of the high pressure fuel pump plunger.
3. High pressure fuel pump camshaft lobe.
If the base of the cam shaft follower looks like -C- or -D-, no excessive wear is present.
Cam follower and camshaft should not be replaced.
If the cam follower base surface is excessively worn so that its surface is concave -B- or missing -A-, inspect the intake cam shaft lobe for wear.
![Image]()
If the high pressure fuel pump camshaft lobe shows excessive wear, replace the intake camshaft with Part No. 06F109101B and the cam follower with Part No. 06D109309C, see Group 15 Engine - Cylinder head, Valvetrain in ElsaWeb.
Inspect the tip of the high pressure fuel pump plunger for excessive wear.
If excessive wear is found the high pressure pump must also be replaced, see Group 20 Fuel supply in ElsaWeb.
Tip:
High pressure fuel pump plunger damage is only possible if the cam follower base has a hole in it and the plunger tip has come in direct contact with the camshaft lobe.
If no excessive wear can be found in the high pressure fuel pump cam follower or intake camshaft lobe, or if the damage is found in camshafts with part number 06F 109 101 B, create a Technical Assistance Contact Ticket under the Concern Type Engine and Engine Electronics in ElsaWeb.
Attach the complete diagnostic log to the contact, and call the VW Technical Assistance Center for further assistance.
