Lambda Sensor defective

Anyone had the same issue?

Dealer wants £2,850 as its apparently an engine out job.
Appears to be incredibly expensive.

By the book the front lambdas are an engine out job, sensor is a mere 150 pounds or so.

Talk to Grizz/Unit 20 for example he has said several times they can swap lambdas without removing the engine, should save plenty of money that way.
