I recently posted about a problem i have noticed since getting a magnex fitted. I think the mechanic who fitted the exhaust damaged the Lamda sensor. My local specilalist garage do not have the correct pod to hook my car up to, to run a diagnostic check. They only have the equipment to test clios up to 1998. Mine is a 2000 clio 172. He has said they could hook the car up but it may not pick up the problem. Do i spend the money and let them look at it or do i take it to Renault who i want to avoid like the plague, as my local renault is quite far away and they are useless...What do you guys think ????
