Traded in my 2.2Dti SXi and picked up a 3.0 CDTi 55 plate. It had been sat around for 7-8 weeks so was a bit sluggish. Did Ikea and escaped on under £50 then for the drive home up the M1. Sat in the resticted 50mph zone with the power coming on and off and nice clouds of black smoke making other drivers drop back!. Nice little <spanner> pops up, so dive for the hard shoulder and ingition off, start up and <spanner> cleared. Happend 4 times. Got home some 60 miles later and 1 mile from home the <emmissions> light comes on....arrrggghhhhh. Got some Redex for the fuel, and Wynns "stop smoke" for the oil - nut no luck. Disconnected battery for 15 mnutes - still <emmmissions> light on. Breakdow said couldnt do anyhthing and it was the "lambada" ??? sensor (thought that was a dance!). Said disconnect it foer longer - so left it an hour and a half.Current status as of 10 minutes ago - still got my <emmissions> light up , wont go above 3500 revs,a nd dirves like 80BHP not 180BHP :-( any ideas???
