Hello, new here. Lots of info, great site. Recently aquired a 99.5 jetta TDI wih 390k on it. Experiencing a few issues that i could use some ideas on. First of all, crank time is a little long, cold and hot - 5-6seconds. Haven't looked into this too much yet. More importantly, driveability has an issue. Low RPM idle-2400, is OK and pulls pretty well. Above 2500rpm or so, the engine just does not want to rev. Also makes vibration/noise when pushed to 3500rpm or more and really struggles to increase RPM. MAF value maxes out around 790 (a little low for WOT?), turbo boost matches spec within 100mbar, pump timing is within spec - advanced and around 80-90, intake is not clogged, no snow screen, new air filter, new fuel filter, fresh fuel. Recent repairs include turbo actuator, n75 valve (swapped EGR valve), air and fuel filters, timing belt. Im thinking of checking the in tank pickup for clogging next. Any other ideas? Ive never seen a plugged cat on a tdi, but on a gas car would result in similar issues. Thanks.
