My genuine MAF has been in 2 years no problems, the genuine plugs almost a year, I can see the sense in buying Volvo parts.....you save in the long run.

What are the other dials you have ?? I know the boost in the middle, butwhat are the left and right ones??

[960kg]

gsf £130

i went to my local volvo stealers.... only £238 + Vat :/

They are not stealers!........i support them whatever because if you don`t use then they won`t be there for you or the prices will be so terrible you would have to part with your motor!

Already my local Volvo Dealers are selling other marques to break even so by not using them the situation gets worse....also so does the car as they don`t work as well either....so it is eventually up to the individual what he wants!

Ok, if one wants to own a mongrel of a car, bits from here bits from there but i prefer to have my Volvo the reliable motor it was from the factory, if one starts to fit aftermarket parts for the engine only then you won`t know when to stop spending if it doesn`t run correctly!

£238 for a MAF doing at least how many thousand of miles is a steal ,on your part.

i know what your saying..... but its the exact same bosch unit from GSF but half the price, and volvo were saying Wednesday

just had another ££££ drive to the next town, got blown off by an old fiesta

cheaper than £130?

[Brett855tdi]

the one on the left is a wideband afr air/fuel ratio
the right is a dual stage boost controller (which the led numbers are useless, hence keeping the boost gauge)
and it lights my face up like an avatar at night... needs a solution maybe tinting it

yes mate

[Brett855tdi]

fitted new bosch maf and running ok
still idling at 1150

still got po171

i have my ebc between the tcv and wastegate

fully turned up im getting 0.8 bar that fades off to 0.6

i have a 1.2 bar actuator.... do i need to plumb the tcv out but leave it plugged in?

or is it the po171 code doing this?

[stribo]

If you've got an EBC then the TCV can be taken out of the line, and just left plugged in.

[Brett855tdi]

still cant shift the po171 code

bypassed tcv ... got upto 0.9 bar, still fades down by 0.2

the car doesn't seem as quick as before

makes for a depressing drive doesnt it... i think it must be the code giving me the problem... its as if its in a closed loop for the timing

i get enough boost and the afrs nice and rich... but lucky for 200hp i recon
can feel its completely holding back, now started running a bit lean on idle at start up.... but thats the first time at idle since the po171 lean code pfffft

mine idles fine drives smooth and lovely just nothing when you put your foot down

yeah mine was like that with the cheap maf and broken maf, would run lean so easy then cut out.

[Dangerous Dave]

Have you tried putting things back to standard? (apart from removing the turbo)

Just use the TCV.

Also unplug the ecu ovenight to reset it. See what happens.

I cant see using something other than a fully adjusted ebc giving more boost.

and i clear the codes... they only come back as soon as i start driving ... ive reset it 3 times overnight now... theres a problem

ive had 2 mafs on it now lol, (none new though)

[stribo]

I can't remember if you've had new lambdas or not Brett, if AFRs are O.K., then it could be one of them.

[Brett855tdi]

Well the second ones missing but it not bothered it for over a year
I will have a look at the first
