Hey guys,

Looking for some advice as I have been an utter fanny.

I changed my gearbox oil recently and I had a workshop manual for a Volvo C30 T5. I have a C30 D2. The manual suggested that to extract the gearbox oil you set up a tube and run the engine to let the gearbox push out the gearbox oil. I done this with my Mass Air Flow sensor disconnected and the engine ran rough a bit so I stopped the engine.

After swapping out the oil with a syringe I put it all back together. After the engine was running rough so I popped a OBD2 diag tool to see if any errors were throwing up. It initially came up with the mass air flow sensor error but it also comes up with a manifold error P0069 that won't clear.

I'm a bit stuck with what do to next because she was running perfectly before I under took the work. My friend suggests I may need to clean my lambda sensor but I know that's a tricky job so I thought I'd get someone else's input in case I just need a more sophisticated tool to clear an error or maybe have to recompress my engine.

All input would be greatly appreciated.

Thanks in advanced.

Fanny
