Boost Pressure Sensor - How To??

Hi,

New here, read through the FAQ's but nothing dedicated to this one! Car is Alfa Romeo JTD GT 55 reg

I've had a diagnostic done, it's the Boost Pressure Sensor causing my overfuelling, low boost, heavy smell of fumes. I've bought the correct Bosch replacement part (thought would just buy new rather than clean up etc) but I don't know where to head and change this.

Is there a DIY guide for this about? If not, could anyone kindly explain? It looks a simple plug and play type piece of kit but I've only just moved to Alfa from BMW...

Many Thanks

Nope different thing but thanks anyway

Incase anybody needs to replace this (fault comes up on Diagnostics) then this picture may be useful that I found on the alfa workshop site

Number 9. I switched it over to the new one and it's hugely noticeable. Turbo picks up well, car doesn't wreak of fumes from the overfueling and generally a nicer drive. Well worth the £40 diag + £40 for the part!

Turns out it's described under both names. If anyone else needs to buy one: 0281002437 Bosch number

The original one looked clean as a whistle (cars only got 30k miles on it), so uncertain whether cleaning up would have done the trick.. Anyhow, all sorted so happy bunny again
