Ok, new to TDIcliub and love the info.
Recently purchased (June 2012), 1999 Jetta TDI Mk3 GLX (1998.10 Mfg)[312,000 km] and have replaced the Oil/Filter with 5w40 [Edit mistype 10w40] Castrol Syn, and Spin-On Oil Filter.
Intermittently get 3 symptoms and possible two problems.
P0506 (ROM checksum Error), and
P1550 (wastegate /pressure differential)
-and-
Intermittent will loose power, then blink CEL , but recover.
Recently, drained fuel/water filter/separator, and all kinds of black carbon deposits came out, threw out deposits, checked for water in fuel. Tighten everything back up, re-prime filter buy running on idel for 3-4 minutes.
Take road trip for test run, 1/2 hour drive , Highway country road driving (80 Km/h). get P1550 error again.
Notice frayed vacuum hose that leads to Air Intake cover (Air FILTER) to left of MAP(??) sensor on air intake after filter.
Replacement hose on order, but was unsure at what would cause the sudden loss of power for 1/2 second while under load, or accellerating with A/C on.
Usually Occurs around 1600 RPM, but not always.
any pointer(s) will be appreciated
