Hi I wonder if anyone can help pleas.
I have a 2007 Passat 2.0 TDI BKP.
The car itself is ace and drives fantastic but just recently it has started to flash (engine fault garage) on the dash and then the glow plug light flashes, if you stop and turn the engine off and on it then drives fine. This happens when you put you foot down and never happens in to when doodling about.
I scanned it with VCDS an it came up with the fault 000564 - Boost Pressure Regulation/P0234 - 006 - limit exceeded (overboots condition) - Intermittent - MIL on
I took it out today to gather some data on actual boost and specified boost an interestingly enough when driving around town it stays more or less steady, however when you put your foot down the actual boost is somewhat higher, when the fault appears there is an almost vertical line on the graph of the specified boost and then both the specified and the actual boost then drop to the bottom of the graph and then you have limited power as expected as I'm presuming that the ECU has gone into limp home mode.
Has anyone experienced this before?
I would be very grateful for any assistance.
