Utter fanny
 

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.

Hi Dave,

Think you might have got a better response posting your query in the C30 section rather than the Events and Meetings thread.

Perhaps repost and fellow owners migh5 be able to assist

Cheers

Just unplug the Lambda sensor and see if it runs better!
It will obviously give a EML code and put the EML light on, but if you have a code reader this will usually delete the code and turn off the EML once you know if lambda is at fault.
