Clio GT 1.6
So I have a 1.6 GT Clio, the emissions light came on Monday so I went and had a diagnostic done which confirmed it needed a new Lambda Sensor. Apparently 6 sensors were tried, from 3 different stockists and none of them fitted the car. When the garage rang the 4th stockists they were apparently told that they're a hard piece of equipment to come across and that only way they could be ordered was through a Renault dealer. Has anyone else had this problem either with a GT or another specialised model, as I didn't have the bother with my bog standard Dynamique Clio. The car is in an arse with itself, runs like a r****d above 30k revs and its lost its bark 
Obviously I'm not best pleased as my quote of £70 has now shot up to £225
and I'm not experienced enough to try and do the work myself or to find someone else to do it
