I have an XF (2016) with about 100k on the clock - since October the engine management light has been on (solid amber) and it has covered about 3,500 miles since then (bad idea I know, but the dealer who sold it to me several months prior was not playing ball and I had no alternative vehicle). A Land Rover garage took a look and advised

"We looked at your car for a possible EGR valve issue. It had a fault code P04913 was logged which indicated a problem with flow through the EGR system. When the exhaust was checked we found large quantities of soot deposits on the tail pipes. In our experience this indicates that the diesel particulate filter has broken up inside and is not operating correctly, by allowing gasses to escape past it and sending them back into the EGR system and blocking the filter. In order to resolve the issue we will need to replace the DPF and clean the EGR filter for you."

Before I drop £2.5k going down this route, can I please ask whether this sounds right to members of this group, and whether anyone has had similar difficulties. Thanks!

 

It does have a ring of truth to it. A few years ago when I had a petrol XJ6 (X350 model) the Jaguar specialist showed me an EGR valve off an XF. It was all clogged up. I asked if cleaning was an option and they told me it was possible but they always put a new EGR valve because if the labour to clean it meant it was cheaper for the customer to have a new and warranted EGR valve. DPFs can clog up if the car use pattern is lots of short journeys with no opportunity for the regen programme to start, or if started, to finish. However, although they replaced EGR valves regularly, they never mentioned the DPF.
What engine ? (obviously a diesel).

 

Just end that nonsense. That nightmare can end really quick with a few pounds. Just hack it to bypass all that adblue bul**it.

Done. No more problems.
