Have a 2005 Ztt 130 which I have owned for a year and a half. Its been a money pit from day one!.
Anyhow the last big expense was a full injector overhaul during which I had to pay someone else to get the last injector out, took 10 tonnes of pressure so I was never going to get that out by myself!. When I got it back into use after that I suspected exhaust fumes in the cabin, headaches after any journey more than a few miles etc. Before I got round to looking at it she let me down again with a fuel pump failure. At that point I parked it up and left it for a while. Now back on the road with most but not all of the many jobs it needed done, I had forgotten the exhaust issue, obviously now it is a problem again. So far have replaced pcv valve with BMW version with no filter, cleaned EGR (Exhaust Gas Recirculation Valve), cleaned inlet manifold, check exhaust flexy etc etc. Still got the problem. HELP!!
