Faulty NOx sensor

[adflyer07]

'04 1.6 FSI Golf MkV - earlier this week the yellow "engine" warning light came on whilst on the motorway. After a "1 hour diagnostic exploration" (£85+vat) the dealer told me it needed a new NOx sensor (£256+vat) + fitting (1¼Hrs@£85ph+vat) grand total £525.

The car has only done 24,500 miles, should it need a new one of these after this time? Is there a "fit for purpose" disagreement brewing here?

On idle, the exhaust sounds a bit rattly - could it just be a faulty /perforated exhaust rather than a faulty NOx sensor?

Aside: can any back-street garage maintain cars such as this these days or does it need tech gear that only the VW dealers have?

Cheers, Alan.

isn't your car still in warranty? yes rip off prices i agree! i would be asking for some sort of goodwill from vw!! 1.6 mark5 FSI do sound a bit raspy though. good luck
