Evening everyone,

My 2.2 DTi keeps going into limp mode whilst driving (partial throttle but only when been stood idling) and puts the EML warning on the dash whilst stationary but idling (especially when facing uphill).

Reading quite a few threads today (I am no mechanic btw), it seems that whilst P1635 refers to glow plugs (all of them are working been tested at a garage with wire from battery to the glow plug tips), it is the P0400 code which is the main cause for concern.

I could clean the EGR and looking at the O seal but that seems to be a side issue but good practise anyway.

There was a thread about a VP44 (whatever that is) but it seems they very rarely fail.

What seems to be the issue is either air in the fuel system, leak bad pipes that aren't leaking back, sticky injectors on partial throttle or injectors seal knackered.

I use cheap supermarket diesel, so have bought some injector cleaner to see if that helps and as well as using the carb cleaner for the EGR valve, I have read that fitting a priming bulb on the 10mm pipework (before the filter ideally) would help as would a new diesel filter to check for water.

Am I in the right area chaps?

52 plate 2.2 DTi if that helps


Regards Neil
