E46 02 sensor, car malfunctioning.

[matthias73]

e46 330i pre-facelift. Kept cutting out on motorway speeds whilst on holiday. Took it to garage. The following came up:



This was 4.30 on a Saturday and they were closing. Unplugged the MAF thinking it would override all 02 sensors and in theory make the car run.

That worked, holiday and relationship saved.

However I now need to sort this out properly. Anyone tell me what this sensor looks like and if it's something I can do at home?

(I do routine servicing myself and have access to a servicing bay and qualified mechanics at work, although they are rather busy)

If that's the cause of your fault it's not hard to change. Put "lambda sensor socket" into Google, check what size you need, think it may be 22mm.
