2.2L Diesel, the one with the 2 stage turbo from 2007 in the UK. Done 145k miles. Remapped at some point in its life. Camper conversion.
So it has been working fine, I am driving round Europe and have 2 error codes. P1955 which is a glow plug issue. Not really a problem right now as the weather is fine and the engine starts almost instantly anyway.
The other error code is P0299 which is turbo underboost. Every so often, the engine goes into limp mode and I get a CEL but it doesn't affect anything else. I just flick the key off and on and bump the engine and its fine again. This only happens if I sit for a while with a really low throttle position. If I drive normally/aggressively, I have no problems.
Anyway, the other day, as we set off in the morning, a really strong hydrogen sulphide (rotten egg smell) appeared. It lasted maybe 30 minutes and then went away. I was driving 3-4 hours a day. Next day same thing. Next day, no smell at all. Next day the smell was back, really strong. Finally today, no egg smell but then after driving for 2+ hours, we got a small whiff of egg for 30 minutes or so. Not as strong as normal though.
I can't really think what this could be. The batteries are not being overcharged, checked voltages of both the engine battery and the 2 deep cycle batteries on board. No boiling or anything. Either way, the smell is way to strong to be from the batteries.
It isn't anything to do with our waste water tanks, checked everything. The smell is so strong, it just isn't possible to be anything other than engine / fuel related.
If it was weird/cheap diesel from Eastern Europe where I am now, surely the smell would stay or would the exhaust heating up stop the smell?
Are there any checks I can do to narrow this down?

or £75 from home. So it's on its way from the UK.
