1.9 PD BXE PASSAT 08 PLATE (165K)
Hi all,

Car is 1.9 PD TDI PASSAT, 08 PLATE, BXE with 167k miles. Recon engine with new clutch and dual-mass 50k miles ago, new recon turbo installed 5k miles ago from old owner.

air filter changed, MAF sensor cleaned, battery changed, camshaft position sensor changed and coolant sensor changed all by me recent.

The car is ok to drive but some things seem off:

1. Turbo doesn't kick in till 2K RPM. This seems really late.
2. I think the exhaust smells way too strong of diesel at idle.
3. Some white smoke on startup from cold. Not much
4. Economy seems poor, only via MFD, 25mpg around town. I know I should do a full tank to tank but I still think the MFD should be higher and my idle econ on VCD is 1l/h which I believe is too high.

I bought VCDS so can provide any figure your request to help me. Below is the following data I think is relevant, pulled whilst at 90c idle:

14:48:02 Group 001: Injection Quantity
819 /min Engine Speed (G28) Under the acceptable range of 860+?
9.3 mg/str Injection Quantity Over the acceptable level of 8?

14:48:02 Group 003: Exhaust Gas Recirculation (EGR)
819 /min Engine Speed (G28)
260.0 mg/str Exhaust Gas Recirculat. (spec.)
415.0 mg/str Exhaust Gas Recirculat. (actual) This is way over the acceptable?
95.5 % Exhaust Gas Recirc. This is way over?

819 /min Engine Speed (G28)
0.0 °BTDC Injection Start (specified)
8.7°KW Injection Duration (specified)
-2.9°KW Torsion Value Should be -0.5 to 0 I believe, worth adjusting?

14:49:59 Group 005: Start Conditions (last Engine Start)
819 /min Engine Speed (G28)
17.8 mg/str Start Injection Over the acceptable range but perhaps doesn't matter as it's on start?

-0.49 mg/str Injection Quantity Deviation Cyl. 2
-0.56 mg/str Injection Quantity Deviation Cyl. 3
1.65 mg/str Injection Quantity Deviation Cyl. 4 This is within the limits however I believe this injector is too high and the others are compensating?

14:53:12 Group 015: Fuel Consumption
819 /min Engine Speed (G28)
61.0 Nm Engine Torque This is way over the acceptable?
1.00 l/h Fuel Consumption This is way over the acceptable?

So it looks like I have an injector that needs fixing on cylinder 4? or perhaps the torsion value needs setting to zero which will sort this out? Or maybe the MAF sensor and exhaust gas recirculation valves are wrong and there are vacuum or boost issues? Any help would be great, I am willing to tackle these but need the forums experience to guide me. Please note the following error codes, they have been cleared and haven't returned yet:
