V70 mk1 non turbo lambda sensor brands choice

[Barnoluk]

Hi all,

Need some experience from folk that have lived this. Lambda sensor needs replacing.

Volvo have one for £250
Can get an ngk for £120 ish
Scandal for £100 odd
Bunch of other brands like hella and meat and doria

I’ve read endless posts that it must be a Volvo part or face carnage, I’m good with this. If I must order from Volvo I will.

Are there any other credible known options from among the above or wider? Even if it is getting the same part quicker or cheaper?

I just want to do this job right and once but Volvo is also a 5 week wait.

Thanks for listening!

I've replaced a few lambda sensors over the years, the one that gave me trouble was when I went cheap and bought a 'universal' type from ebay, lasted about a month and went wrong again. As I recall last time I changed one I took the old one out and found it had the Bosch logo and part number on it so I got another Bosch one from the local parts shop, if you're not using the car it might be worth a look.

Cheers David, I agree totally. The issue I have is that I can’t find a Bosch part anywhere!

Not sure if the V70 has Bosch as original fitment. I have replaced original sensors on V40 by removing the old one and reading the part number and buying a direct replacement. NTK were the original fitment. No issues at all.

Hi Barnoluk

What year is your non turbo V70?

Do you have the old sensor off?

What is the Volvo part number that you are looking for?

Hi Steve, no I don’t have it off yet. It is 9207999. I have just noticed that the hose between air box and throttle body is split to hell, I wonder if that might trigger the lambda light?

I bought an obd reader but can’t talk to the car to check codes. Frustrating

[Barnoluk]

It’s also a 1998

OK, when I saw your first post I was very tempted to ask why are you changing the Lambda sensor, now I'm definitely questioning this. I doubt if the hose you mention would massively affect the mixture, as this is before the MAF sensor, but if all you're doing is trying to address the engine management light, then changing the Lambda sensor is just guessing - it could be caused by a hundred other things, and Lambda sensors on these don't tend to fail particularly often.

If that hose is shredded, then others may be too, including vacuum lines - statistically speaking this is far more likely to be causing your problem IMHO, so well worth a thorough check of all hoses and vacuum lines and replace where appropriate.

However, my advice (and many others on here) would be to solve why you can't read the codes from the ECU - you really need to know what code it has thrown, so you have a fighting chance of addressing the right area - guessing is time-consuming and expensive. Lots of advice on here on how to read codes, and what scanners etc. to use. Yours should be OBDII compliant, unless it's a 10V engine (I think?), in which case others on here will tell you how to read the codes.

By the way, in spite of the symbol on the dash, it's not a "Lambda Light" as such, it's an engine management fault light, when the engine is running it will light whenever the ECU detects a problem in any part of the engine management system, of which the Lambda sensor is only a small part.

Thanks for the message, it is a 10v and the reader I bought was useless.

I have a 10v 850, which I think has the same engine management system as yours, and managed to fit a Bosch lambda sensor from an 850 T5... You have to file a bit of plastic off the plug to get it to fit as the connector is subtly different, but otherwise it seems to work fine.

Part number is 0 258 005 097, seem to be widely available online for £60-£80.

Agree with Luxobarge though, you need to read codes and find out what the issue is first...
