Thank you for your detailed reply.
I see where you are coming from with the 'worried part' I am also worried now. I am now in negotiation with the rebuilders for an extended warranty on this engine as I only do about 2000 miles a year if that.
I will certainly do the ALDA adjustment as per your instructions, or more precisely: have it done by a trusted mechanic.
Would you recommend having the overboost protection fitted and if so where could I cource one from. The turbo has been rebuilt as well to be on the safe side
as has the gearbox/radiator/oilcooler/starter/alternator............
The rebuild shop is picking the G up tomorrow as I flatly refused to drive it to them with a leaking injector. To say I have lost confidence in them would be putting it mildly and these guys are the TOP Mercedes rebuilders in the UK.
I suppose what I am really looking for is more low down torque which is usefull offroad.
Thanks again
G.
