Hi everybody!

I had a strange thing with my late 2011 159 2.0jtdm 2.0 TI Alfa.
One morning I started the car and Average consumption jumped from 7.0L/100km to 10.1L!
And kept climbing like 0.1L in a minute.
But it seems that current consumption shows OK numbers, but still.

What may have caused it and do I need to worrie about something?

But should'nt it happen when engine is warm, not when cold and first start?

Are you sure it was on average consumption...not instant. If not then something is not quite with it...not sure what though. Probably your own fault for not using the far more sensible miles per gallon! Lol....or even km per litre!

the counter resets itself after certain time or number of km (I think its 100 hours or so)...
How many km (or miles) does it show?

The trip counter resets its self every now and then, when it does the current consumption reflects consumption as normal, but the average consumption fluctuates widely until a good few miles have passed to get a stable average reading.
