A few weeks ago I threw a check engine light, and it gave these codes on my 2012 x351 5.0 s/c. At almost the same time, it became difficult to fill the fuel tank, kicking off the fuel dispenser nozzle unless trickling the fuel in. Looking around a bit, the codes signify a Evaporative Emission System Leak Detection Pump issue. Is it common for these to fail? Are there other issues that are consistent with this issue that I could check? I searched and found only one other post relating to this, and the owner said that replacement is a five hour job because the diff needs to be dropped? Has anyone else had any experience with this? I appreciate your feedback.

 

I have exactly the same errors in the same model. Were you able to fix the problem?

 

I had this last year,although I was able to get fuel in. It turned out to be the carbon canister and leak pump (they are one unit), was at fault. Jaguar issued a TSB that calls for replacement of the pump/canister and the filler tube, it appears that the system creates a vacuum that is strong enough to collapse the filler tube.

The bad news is that the whole rear sub-frame needs to be dropped out for access to the pump and tank. Mine cost just North of $2600 at the main dealer.

I can easily fill in fuel. Only the check engine is lit and there are errors as above. I read that it can only help save the outlet, which is at the filter number WTR500030. What do you think?

 

Cameo,

When I pulled the codes on my '12, I also thought it would be an easy fix...wrong!!! As soon as I said "P2402" to the service manager he replied "Carbon canister and pump, have to drop the back end, 5 hours plus parts. $2650. Here's the TSB".

Other than staring at the light, there is no way around this one.

Sorry again,

wombat

PS. There is a 1/1000 chance that cleaning the contacts to the pump might fix it, but I doubt it.
