    I have a 1997 S70 2.5 20v. The lamda sensor warning light has come on three
    times over the last 12 months and been reset by volvo twice. Volvo say
    there is no fault but charge me £22 to reset it each time. I have noticed
    that each time the warning light comes on the road has been wet but other
    than that I can find nothing wrong with the wiring etc. (the Volvo dealer
    tells me that it is the rear lamda sensor which is throwing up the fault).

    Any ideas?

  2. Nope.

    A tip i got for removing the warning lamp. I get the warning too,but for a
    different reason.

    reset light by:-
    open bonnet
    open fuse/relay box by airfilter
    remove rear 2 fuses (one is yellow,one is red)-control ecu and fuel ecu,
    just the back 2!
    refit fuses after 3minutes
    refit lid of fuse/relay box
    shut bonnet
    start engine-no lights!!!!

  3. The lambda warning light on my '98 V40 began to come on intermittently ...
    checked with dealer who said the sensor was probably at fault but to watch
    for change in pattern of behaviour.
    Sure enough it came on never to go off just before a long trip. On return
    the dealer wrote off the sensor and fitted a replacement at a cost of in
    excess of 280 gbp - fortunately the car was still under warranty.

    Hi andy,

    I have the same problem too with my V70 T5.
    First they resetted it for me, but after a while, about 4 weeks the problem
    appeared again. after they replaced a new lambda sonde I thought that the
    problem was solved....but NO....

    I got to go 4 times back to the garage to fix the same problem.
    The last time they found that a small play between the engine and the
    exaust branch pipe.They finally fixed the
    sealing and said the problem was over.

    But I drove the car for about 3 weeks then the lamp light up again. then I
    went back to VOLVO again. and this time they replace a new sensor for me
    until now... 4 weeks later the lamp has not lightened yet. But I'm not sure
    whether the problem really has solved. I'll keep you informed abou this
    o.k.???
