Poor Economy!

Here you can talk about the joy owning a Volvo 480 brings. Non-technical discussions take place here, like what is the difference between an ES and a S version.

1. The very top bar of the fuel gauge (digital one) is always missing even it is fully tanked up..Is it normal? Or does my fuel gauge just missing out that green bar by faulty sensor / IC electrics...etc?

by the way mine is a 94 ES with a 60L tank, I presume...

Many thanks! (as you can tell, I'm very new..glad to have joined the club though, please bear my ignorance! :)
I had this problem with mine. The fuel gauge was just badly calibrated, but it's easilly rectified.

Next time you fill up, make sure you top it up all the way with every last drop you can. Then before starting the engine, take out the info centre control switch. If you are carful, you can take it apart (may not be necissary, but only way I could find to do it), you should see an extra blue knob in the middle. Hold down the reset key and turn the electrics on (no need to start car) and it should go into a sort of setup mode. Select the range option, and then move the blue knob until 60l is displayed on the screen. Put everything back together and restart the car, and hopefully it will work.

I also found because I was filling up earlier than required (although not with as much fuel) it seemed like I was getting about 50 miles less to a tank. I average 400 to a tank on it now, or upto 500 with good driving, although it's a 2.0 and I don't drive much over 70mph often, that said I do use the torque on offer quite a bit, so I'm really quite suprised with the fuel consumption. Also I only ever use Optimax fuel, it does (IMHO) make a difference.

So to recap, if my fuel consumption is getting close to twice what it should be according to the specs posted on the homepage (as they are :( ), I should try:

- cleaning the fuel injectors (with RedX or whatever the name is?)
- check tyre pressure
- or have it retuned + gas treatement (wasda? ie. could you explain what you mean with gas treatment please?)

how did you clean the injectors? Just chucking in a can of injector cleaner doesn't do all that much or nothing at all

When I had my 480 tuned the guy doing it used injector cleaner and gas treatment, it made the world of difference, see here http://volvo480.northernscum.org.uk/for ... t=top+form

ok then,

i have:

serviced it (plugs, leads oil & filter)
have just replaced lambda sensor and air filter
have swapped the boost ecu
have swapped the fuel ecu
have swapped the maf

not made sod all difference i am still struggling to get over 20mpg!!!!!!

ARGGGGGHHHHHHHH!!!!!!!!!!!!!!!

:badmood:

Any ideas?

Adjust the MAF? how would i go about this?

can't think of anything else.

Car run/drives good no flat spots/odd noises etc. no power loss.
1 thing i do no is re-circ valve is fluttering (broken diaphram or something?) but surely this wouldnt have that greater effect?

:badmood: & :dunno: !!
