Bosch make different specs of Lambda Oxygen sensors. I've heard of 4.2 and 4.9. They are wideband sensors, normally only about £100 each.

Don't know if 4.8 is another spec.

I also notice a Lambda "conversation" at 35 quid. That'll teach you not to talk to technicians when they're hard at work.

Perhaps the 4.8 reference means they are the same as fitted to the later Aero's with the BMW 4.8ltr ?
