Hi guys. I have a 53 plate 320d saloon. I have read through alot of post on here and other sites but unfortunately I'm still having issues
This is a long one but I figure I will get the best help if you guys have all the info so please bare with me
Basically my power output is all over the place. Sometimes it pulls well right through the rev range with no smoke
Other times the low end torque seems about right but as the revs build the power dies off and I get black smoke.
The third scenario is quite rarely I set off with good torque no midrange then a kick in the back at about 2700/3000rpm ish.
All the time I can hear the turbo spooling up, there are no random noises and it only really smokes when it loses the power.
I have done oil + filter (10-40w ll04), air filter, half decent clean of egr, inlet manifold, map and maf sensors. While I had the inlet off I had a good look round vacuum hoses, they seem ok, fabric torn in places but rubber seems good. Oh and read for codes with a cheep obd2 reader only one is for cold start injector short
I'm getting some caustic soda to soak the inlet this week and I will soak the egr in petrol at the same time for a thorough clean.
I'm going to clean and check condition of all the hoses from the airbox right through to the manifold. I will check for play in the turbo at the same time. Also on the list is fuel filters.
Just underneath the airbox is a servo motor of some kind that keeps clicking randomly from the moment I turn the ignition on right through till it's turned off. Any ideas on that?
Any thoughts pointers ideas are all appreciated.
I might even be open to a can of petrol and a match lol
Thanks in advance guys
