Hi today while driving and running on the low side the obd says reserved tank, is there really a reserved tank in the vehicle? Mines a 2004 clk. If so what mileage can I achieve on the reserved tank.
Its your last bit of fuel, on reserve ive done 40 miles on it before in my CLK 240...wouldnt recommend it as at the bottom of your petrol tank there may be 'dirty' bits
In the old days there actually was a separate small tank. My Dad's 1960 VW Beetle required a lever to be moved to open this tank...and then the car would go again!
My CLK has on one occasion got down to 0 miles left. It had 140 remaining when I left home to go and do a 2 hour job that took 8 hours and was well past midnight and no garages near to me.
When I eventually pulled into one it took 68L (in a 65L tank) and where it always starts first crank, this time it took 3 or 4 goes to pressurise the system.
I actually pulled off the carriageway and drove through town as I figured it would be easier getting a taxi home from a street than a carriageway.
I'll not be doing that again.
