'99 Tdi 110 - Req. Boost Values

[alan_131]

Hi All. I've a late '99 TDI Ghia which is sick in several ways. I've tried the 2000-4000 test and I'm getting REQ. Boost values under 2000mB across the range. I think the 110 spec shows boost about 2200mB at max power. My actuals are typically 200mB below req.

Getting to the point - can anybody tell me please if the ECU should be asking for 2200mB+ somewhere during the test or is this lower value normal under some circumstances - eg protecting engine for other reasons. No fault codes at the moment.

 

The car's been tinkered with by somebody who was not neccessarily too concerned about detail in the past(eg fuel lines not clipped in properly, odd bolts missing, MAF working but mismatched connector) so could be a number of other things happening at once.

 

Any suggestions gratefully received...
