Vauxhall Zafira 2.0 TDi 2003 - Fault code P0105, P1105 and black smoke #

Posted by Martin bebb on July 25, 2010, 10:35 pm

Year of Manufacture *: 2003
Engine Size and Code *: 2.0 tdi

I recentley gave my Vauxhall Zafira a full serice but it still bellows out black smoke. no power loss.

Also I'm getting the following fault codes. IAT Sensor voltage high. P0105 boost pressure not plausible with barometric pressure and also P1105 barometric pressure sensor not plausible with boost.

I think the course of the black smoke is fuel richness. If you are reading this do you agree. what do i check and what do I do.

As for the codes I've taken the car for a drive with my solus in graphing mode hopeing the codes came back so i could read the live data but it never happens when you want it to.

Any idea on the fault codes.

Hi Martin
I would check (blank)EGR valve & see if this improves smoke, Also check for air leaks might have a leak on intercooler

Check the MAP as well, they get blocked with soot.

I would go for new boost pressure valve.
