Can any one help .please.
i own a renault laguna 2.2 dci on a 52 plate had an intermitent problem over the last few month
the yellow light looks like a
or heater lightcome on under hard excelaration
but graduly got worse some days wouldnt even start then i heard a noise under the back seat (groaning)
fuel pump at last i thought i knew the problem
so of to my local renault dealer and the yorkshire war cry began (how much) so off we went to the local breakers yard no 2.2 dci in stock but he did have a 1.9
so i took that and the manual ball pump all fitted and all good works a dream .
now i have found out it wasnt the pump it was the fuel shut off valve in the high pressure pump .but i also have a red engine warning light saying stop flashing .i have pluged in an obd 2 and the system is saying "heated oxygen sensor high" i know it aint got a lambda sensor fitted thats 2005 onwards help please b4 i go broke
