Hello and first of all pardon me for my possibly bad English; since im from Finland.
So, to the issue:
Background:
-320cdi
-2001 facelift
-297000km driven
-crank- and camshaft position sensors replaced
-maf recently by old owner
-turbo and cylinder head due to egr fail -> all changed and egr disabled via ecu and mechanical plug
- motor flush + oils and filter
- transmission oils
- less than a year old battery is (stress) tested -> all good
So the actual problem is that the engine cranks bad when its warm. Now that they changed cps/cam pos. sens. it cranks little bit more frisky, but when warm; problem is still there. Should i change the start motor next? Battery voltage is ~8 when cranking and 13 when driving.
The garage fixed some fuel leak next to rail pipe/or something like that and one Fuel gasket are to be replaced next week.
Second problem is that the automatic gearbox goes into limp mode*/ it changes bigger gear fast and kickdown isnt working. When i stop and restart, problem goes away for awhile until randomly it comes back.*
*Soo i recall its not actual limb mode, with only 3000rpm and 2nd gear only. When problem ia there, all gears are used and if i manually select for example 3rd, it goes to redline and there is plenty of power.
(Im wondering if the gearbox itself is failing or some sensor limits the power output)
[When the transmission works fine, all power is there and car runs normally.]
Sucks to have ~200hp diesel when all the Japanese rice-cups overtakes all the time*[https://mbworld]
Last thought: is it just me or is there a big turbo lag on such big (3.2l) engine? I feel like its only 2700-3000rpm when it pulls hard and the best pull is over 3500rpm.
Compairing to wife's 2.2dci laguna which pulls waaaay friskier and from like 2100rpm. Merc has more power at higher rpm tho.
Thanks for your time
