Which new O2 sensor for s70r?

[Kingsford G]

As above.Been searching and found a Denso and NTK for a reasonable price.Has anyone had any experience?Also which is the more important one or do I replace both?

[siamblue]

I thought the sensors were Bosch variants.

[Al115]

They are, I think.

I used http://www.lambdasensor.com a few years ago and was impressed with the service and price.

It`s entirely up to you what you fit, but fit ONCE as it will get expensive if the ones you thought were ok turn out to give error codes or whatever.

You can get cheaper than Volvo`s own but are they good enough?

The front one is the most important for general running of the engine but although the rear one is mainly to check that the cat. is ok it does send signals to the front one and they do work in conjunction with one another thus sending the correct signals back to the ECU for fuel mix ect. which ultimately is performance whether get up and go or mpg.

They can last from 60 to 100,000 but after that although you may not get a light up they are past there best. They wear at the same rate.

When i have my T4 i replaced both at 112000 just for maintenance and there was a heck of a difference and was money well spent.

I always buy Volvo with anything to do with the engine......as in another thread the chap fitted Bosch plugs and he still had a misfire but then fitted the Volvo, Bosch made plug to volvo spec. and misfire solved!!

So at the end of the day over to you.

Volvo lambda sensors are Bosch ones, IIRC?

It's a Bosch one on my S70R.

I replaced it with a genuine Bosch part from an ebay seller. Can't remember the price now (£60/£70ish?), but it was cheaper than genuine and still genuine if you see what I mean...

The original one I removed had exactly the same Bosch part number.

I'm sure there is a Bosch website somewhere that you can look up the correct part.

Exactly same car as yrs mate even wheel colour lol.Did u notice the dif?

[Yosser]

I had to replace it when I changed the downpipe, so I don't know if the difference was the downpipe or the sensor...

It can't hurt, apparently they do wear out over time. 31mpg at 70 isn't that bad tbh, best I've seen is probably 33, worst 7

[Quicksilver]

Maybe I should change mine, I've never seen 30 in the five years I've had mine!!!
Is there one or two on an R?

If it's a real R then there's only one

well i just got a quote from Volvo for the front lambda, hope your sat down £219.50+vat, my local bosch dealer can get exactly the same part for £85 all in.

Go for bosch oe.I`m sure a genuine one is made by bosch anyway

[Quicksilver]

Yes she's all R!!! Makes a change to have less than a normal T5!!

Unfortunately, if yours is an auto (as per your sig) then it will have 2 - only the manual versions have just the front sensor.

Sorry for the dig about 'real' R's, couldn't resist

i will see what bosch want too do its all part of a claim against them from a faulty MAF they sold me and the damage cuased by it. Im pretty sure they will provide all the parts required.
