.Thank you quick reply that supports what I think myself as owner of cars 65 years.
I was hoping that as an expert in the modern computer aided car age and Mercedes, that you could happen tell me if the fault I discribe was common to that car,and the common repair that was done.
The US forums tend to suggest it could be, has there is a hint of a US recall.
Also as the car, starts, ticks over &. runs.prefectly having done only 31000 miles fully seviced should I concern myself that doing nothing is going to lead to breakdown.
Can I summerise your advice to " take it to a dealer diagnostic check" as that the only sure way with this type of fault?
Do you know of any independent national car servicing that do diagnostic checks?
with a v6 are the two fault codes p0015 and p0025 indecating from two sensors one on each side or could that double fault come from a single sensor?
The case of two sensors having identical faults is unlikely and just a sensor change unlikly to cure the fault.
I bought the car from an independant 18 month ago. The EML came on twice in the first two month and the dealer said it was due to cheap petrol use.I tried the better petrol and it seemed a littlle better while . I was then adviced to do an oil change and make sure that the best recomended oil and filters were used . That again seemed to be a benefit while. The car was seviced & MOT as perfect but this annoying fault came back a week latter
I do little milage and the time between the EML showing is weeks so time goes on.
It seems my first Mercedes after 20 odd trouble free years running Hondas is not a good move or mabe just bad luck with this one.
Out of interest how do the sensors work are they just as the old distributer weights and advance the ignition or do the act on oil pressure and alter the actual valve lifting? If its the latter my engine could have a fault with that item that could prove expensive to repair?
May be that was why someone sold it with when it had only done 25000 mies.
The dealer checked call back thanks
I suppose your answer athough dissapoiting is the only answer to modern car engines. The computer has taken over from experience.
