two Q's for one: Damp rear seats on 306 XSi, also replacing lambda sensor

Hi all
my aging '95 306 XSi is getting damp under the rear seats ... if
you flip up the seats the padding underneath is damp to sodden. Having
a brief scout around this area doesn't reveal anywhere obvious that
the water could be coming in from ... any thoughts?

And whilst I'm here ... can anyone tell me where the lambda sensor is
positioned on this model? How much of a pig would it be to replace?

Thanks a lot

the leak could be coming in from the door seal or from under the car,
best way to find out is run a hose pipe under the car.trying not to get
wet,and your find the lamda sensor on the down pipe of the exhaust ,its
got wires coming from it and it is some time a sod to do.good luck.

You haven't got this fuel problem that is affecting TESCO petrol in Kent and
Essex

Hi Michael

Actually, I may have ... I'm based in Brighton and noticed my engine
was jerking quite a lot recently ... I also topped up at a Tescos in
Lewes a little time before (not sure of dates).

So it was with great interest that I read of these stories. To be fair
though, I have thought my sensor was up for renewal before this ... it
doesn't help that I half-filled the tank with diesel a year or so
ago ;-/. I can hardly blame Tescos for that, but after the grief the
poor thing may have suffered recently I was wondering about fitting a
new one regardless.

[FWIW I also occasionally get the 'engine dies at a junction' problem,
which others have suggested might be due to lambda problems. I've had
the idler stepper changed with little effect]

Cheers
Jon
