Got the 'Lambda Sond ' warning lamp on for the first time ever. Pulled code 241 which is "EGR - low flow through system". I posted this last week and everyone suggested pulling the valve out and cleaning it. However today after talking to both the dealership and my independent Volvo tech they had different opinions. First the parts guy at the dealership said he has never sold an EGR valve or valve gaskets and throttle body gaskets as required by Bay 13 instructions. My Volvo tech says he has never had to replace an EGR valve on a 850 and that it isn't the EGR valve but the pipe from the intake manifold that gets fouled up not allowing the valve to work (makes sense). They are quoting me two hours labor only (no parts) to take apart and clean. What pipe exactly is he talking about and where is it located? TIA
