Another code, this time P010D-00 (AF) Mass or volume air flow B - circuit high. Was happily driving along when I got the reduced engine performance message, and the RRS went totally gutless.

Any idea's if it could be a quick fix, or is it a dealer job (for warranty)? 13MY Range Rover Sport Autobiography SDV6 - mine

A new OEM MAF is around £90. Fairly common issue

Let the warranty pick it up

Thanks folks

While the lack of power is obvious, I'm heading away to work for a few weeks on Tuesday and my wife normally gives the RRS it's exercise once a week to keep the brake discs clean etc. so it this something that could cause more issue's if it's driven? Is it best to not drive it until I get back and arrange to have it repaired? 13MY Range Rover Sport Autobiography SDV6 - mine

I'm not sure if it will cause any further issue but me personally I would not drive it until it's sorted. RRS HSE with a few extras & a

I drove mine last year for about a week whilst waiting for the mobile mechanic. Only noticeable difference was the fuel consumption! It drank about 2 weeks worth of fuel. No harm to the engine, and all fixed under warranty

The last 2 years I had more problems with my RRS then the 40 years I own a classic Alfa(!) not to mention my Mustang Shelby.
British cars always had a name for braking down on the road, but as long you had a toolbox with you and 2 hands, problems could be solved.
With the nowadays cars it is a different story unfortunatly. They prove to be as unreliable as ever, but you are not longer able to fix it on the roadside. where is this going. For me it is like society: stupidity is growing and there is no end to it. RRS 3.0 SDV6 HSE Lux
