Difference between High pressure and low pressure Turbo

Post by charlyW » Wed Apr 14, 2010 11:01 am

Today took my car to the local Volvo specialist who told me that my car may not be a 225bhp T-5 as it's not boosting as it should, I've been saying that for a while, it was mentioned there were several versions of the T-5 variant one with high pressure rest with low pressure they suggested I contact my Volvo agent for them to check via my vin code

Can anyone tell me how my Vin code decodes HPT or LPT ?

No my complete Vin is

YV1LW5706V2339341

I think the confusion has been resolved from the official either US or UK Service manual parts, see added PDF, 57 is the UK 2.3 Turbo engine 55 would be a 2.5 Turbo
