I have a mercedes sprinter 315 07 year 2148cc. I need to cut the co2 (adjust) so I get more miles per gallon heavy on fuel. 2) the brake pad light stays on after the pads were change. 3) The spanner flashes up when starting. The vehicle has had a full service. Can the miles spanner be adjusted with out going to mercedes.Thank you for any help.

car is 24mpg, city.
so 15.6 MPG sucks it does. but is possible if you let my 15yo kid drive car, it is easy, to do, fast right and heavy foot, for sure.

is that averaging 3 tanks, as that prevents ISLAND pump shut off
issues. (varies)
did you check miles with GPS, to see if your speedo/odommeter is a bit nuts?

here are the basics, i can list 100 things, but here are a few.

1. measured wrong. not 3 times avg. (use same gas station and pump) use GPS for true miles. (then switch stations and repeat)
2. bad driving, (teenager? in house?)
3. stolen fuel?
4. brakes dragging.?
5. running 15psi in tires,? (oh'bummer said it ,!)
6. engine running bad, driving with the CEL lamp glowing? DTCs stored, scan the PCM> look see.? fix.
7. never ever tuned it UP, this decade?
8. Pulling a heavy load.?
9. measured only on the up hill run in the rocky mountains, (i just did that)
10. transmissions slips or TCC lockup failing. (scan the PCM)
11. not coasting down hills( cuts fuel 100%) see #2
12. old fuel?
13. ill stop.

thats about 50 km per galon sound about right i have a 1994 mercedes c180 and that does 32 miles to the gallon 300 cc not a lot difference so sould be doing around 35 to 38 mpg depending on how heavy footed he is

Hi, My thoughts exactly ( fuel leak). Is this a deisel or gas engine?
In both cases be very careful with lights or cigarettes.
You can smell it when you get out of car in a garage or stall.
Good luck.

Hi, this really depends on its service history.

The following are the recommended service intervals on the Merc S500:

Note: operate A/C at least once per week, to maintain lubrication.

Underhood & Undervehicle

Every 3,000 miles - Replace engine oil & oil filter. Clean battery terminals. Adjust drive belt. Check power steering fluid. Check steering & CV BOOTS for wear and replace if necessary. Lubricate front end suspension.

Every 6,000 miles - Check transmission fluid condition and level. Check brake pads and caliper components - replace if necessary. Lubricate driveshaft U-joints. Rotate tires. Lubricate wiper arm linkage and pivots.

Every 12,000 miles - Adjust engine valve clearance. Replace distributor cap & rotor. Drain and replace engine Coolant. Replace Air Filter element. Replace Fuel Filter. Replace wiper blades.

Every 24,000 miles - Replace Drive Belt. Replace A/C Compressor Drive Belt. ** Change auto transmission fluid & trans filter (this is critical and must be adhered to) - preferrably do a trans flush at same time. Replace drive AXLE fluid.

Every 36,000 miles - Replace HT leads.

Every 2 years - Replace brake fluid (also clutch fluid if applicable). Replace power steering fluid.


** If you intend to keep this vehicle long term, then consider changing the trans fluid & filter every 20,000 miles. This is the secret to automatic transmission longevity.

You can do all of this yourself if you buy the programmer at autozone...oreilly's etc. Instructions come with it. Expect to pay a gefty price but it will pay for itself in the long run. You can also register at autozone.com for free and register your car and get free access to any online repair manual. You can reset the brakes with the same device.

No such schedule.
spark plug every 30,000 miles
fuel filter/filter element every 60,000 or 4 years
brake fluid every 2 years
cooland every 3 years
oil changes between 14000 or more the FSS indicator on the dash will tell when need to be change

This warnign light means BRAKE WEAR (visit workshop)
Cause:
(Warning) The brake pads / lining have reached their wear limit.

Possible Solution:
Have the brake pasd - linings replaced as soon as possible at an autorized Sprinter Dealer.

I hope helped with this. Good luck.

First things I would look at is,did they put 10w30 oil in and not 5w20 or 0w20,it makes a difference in mileage (if they run out of the correct viscosity oil they WILL put in what they have).
Did the service include a spark plug change?Is the spark plug gap correct?
Did they do a brake service?Is a brake dragging,a little to tight?Did they clean the throttle body?Maybe the engine was running a little lean before and now is at the proper fuel mixture,with less MPGs but running clean at the exhaust.
Weather conditions?Head winds and colder temps reduce MPG.

hey
at the begging u should clarify how many gallon u used.
112 miles at 28 miles per gallon --> 4 gallons burned (112/28)
So that means we leaked 11 - 4 = 7 gallons

Now figure out how long the car was driving.
112 miles at 64 miles per hour --> 1.75 hours

So, leak was at a rate of 7 gallons in 1.75 hours
7/1.75 = 4 gallons per hour leaked.
