Before I start I'm new to this volvo forum, a second generation volvo person with 20 years of ownership.

I've recently bought this car, it clearly had a new front lambda sensor fitted which I did notice before I bought it, the sensor being a Denso DOX-1419

The CEL lights on startup regularly and the local specialist has advised that the rear lambda sensor is tripping the CEL and I need a new cat at £940-00

I am concerned that simply changing the cat is not going to resolve the issue and another new cat will be required very shortly, because we haven't fixed the issue.

Whilst driving the car I notice a very strong petrol odor when the car is warming up or used with high revs particularly when the petrol tank is over half full.

So is the Denso DOX-1419 correct or should I have a new volvo lambda at a whopping £300

Is there anything else I should be looking for other than another car which is what the local volvo specialist is suggesting if I'm reading between the lines correctly!

Many thanks
Carl
