After reading about the fact that they deteriorate over time, I fitted a new one today. It's a 2000 car and I think the TCV is the original. What a difference! Like a different car. Definitely worth doing. Volvo V70 T5

Really? Please elaborate mate :) I clean mine and test it but the idea of spending that much on one puts me off a new one lol.

I fitted mine some two months ago and people think i`m nuts at spending out for one. I think owners forget just because there isn`t rust on our cars that they are really old motors Even Volvo parts wear out.

How much do you pay for a new one for an 850? I fitted a spare one i had kicking about today and noticed an improvement but probably should get a new one. I see some people use mbc's with remap's, is this safe? I don't know if i'd trust myself not to keep the boost low untill after 3k.

[QUOTE=Saaamon;542968] I see some people use mbc's with remap's, is this safe?[/QUOTE] Not adviseable as fitting a MBC will alter what the remap has been set up for. IMH, either fit an MBC and a boost guage or install a remap but don't do both. You cannot design a remap that caters for an MBC due to the fact that the MBC is manually adjustable and the boost parameters can be to far + or - what the remap is setup for.
