well seeing as i've paid £16 i would like an answer !!!!
SD56 PXF ...No warning lights come on when the problem happens .have discovered if i turn the engine off and back on again the problem stops ...bit dodgy when driving at speed tho ...i have had the car four years and it has 48.000 on the clock ...i have done less than 17000 in the four years i've had it ..had it serviced twice since i bought it . I changed the spark plugs today but the old ones i took out were clean with no residue at all .
