Lambda Failures - Z4M

[ian in lancs]

I'm about to get my second lambda sensor. About 5000mls apart. I see from various threads lambda sensors on Z4M's are a bit of a problem. One owner on pistonheads has had 5! Anyone on here have any ideas as to what's causing them to fail

Guessing, maybe it's the heat that get them?

Worst part is that after they changed the lambda sensor, I got a rattle from the heat shielding that they never managed to fix completely . . .

Common on the S2000, had mine replaced when i had one.

Common issue with some TVRs I believe, might be more info on their forums.

Had the two sensors in front of the Cat replaced today. One was showing as 'sensor not connected' the previously replaced as 'open circuit'. Technician said they weren't seeing a run on them and mine weren't as contaminated as some he's seen. Shorts runs shouldn't contaminate them and they're heated too. Although a weekly m-way run would be a good thing to do anyway. He also said choice of fuel shouldn't matter either - SPUL would be better though. So no clues as to the problem / cause.
