  1. Still have it. I had 3 injectors from an AJM bora engine I rebuilt. The fourth one got obliterated when a valve dropped and made a mess. Still had the bits from the old engine and came in handy. Struggling to find a yellow indicator grill at the moment. May have to buy new and paint after.
  2. All good now guys. Swapped injector 2 and 3 and proved fault with injector 3. Replaced and now working sweet. Next on list big clean and front brakes to do. Thanks guys
  3. Same code and misfire. Injection quantity deviation no different when I started. #2 and # 3 way out. Harness new and injector 3 swapped with a known good one. And yes I'm having fun.
  4. Ok guys . All back together. Turned the engine over before starting and cylinder 3 now at 475-500 psi other 2 around the same figures. Cleared all fault codes and started engine. Misfire on #3 still evident. May try the original injector in that position or swap them around any other suggestions?
  5. Well spotted Loop!! Lands look ok . I have replaced the injector with a known good one. Have ordered all the bits I need I can think of. Loads of stripping down and cleaning today. Will let you know my progress.
  6. Got the head off . Valves look ok . Both piston rings broken. Luckily no damage evident around cylinder. Got a big list of bits to get. Any ideas where the best place is to get seals and gaskets?
  7. Spot on Sausage with your recommendation. Cylinder 3 down on compression. 1 and 2 on 500 psi 3 on 100 psi. Head coming off next.
  8. Only have a petrol car tester. Need to borrow one or buy one. Cam lobes look very good with no wear. Alignment of injectors within 0.8mm as per spec. Anyone local with a diesel compression tester? In the meantime I could check the ecu connections and wiring resistance.
  9. Ok guys some progress. Replaced MAF sensor cleared message and no re-occurrence I replaced all the injector seals and still the same misfire with loads of smoke. Replaced number 3 injector with a known good one from an AJM engine I had with the same part number. Still misfires but no smoke!! Need to do a compression test next . messages at the moment 16687 cylinder 3 misfire detected and 17674 pd unit injector implausible signal intermittent. Am I still having an electrical issue here too? Any Help appreciated
  10. After clearing the codes only the cylinder 3 misfire occasionally returns . I take it the readings from the VCDS are what the ECU commands. Also the readings for switch time deviation are (CYL 1 -1) ( CYL 2 -12) ( CYL 3 1) Does this show possibly a fault on #2 ? Will do a compression check to eliminate any mechanical issues Thanks for the replies
  11. Hi guys . I,m new to club lupo as I have just purchased a 2001 TDI (AMF) I bought the car as a project and was aware that the car was misfiring and smoking and showing the following faults: 16485 - Mass Air Flow Sensor (G70) Implausible signal 18072 - control circuit for pd injectors - electrical malfunction - intermittent 16887 - cylinder 3 - misfire detected-intermittent 17964- charge pressure control - intermittent. I have since changed the injector loom with a new vag item, replaced the fuel filter . checked the resistance of the injectors and can confirm oil level is at normal level . The car still smokes ( Diesel smell) but does improve when warm but still misfires intermittently. While running I have taken the following readings : Injection quantity deviation CYL 1 -0.40 mg/str CYL 2 -2.71 mg/str CYL 3 2.99 mg/str Also while the engine warms up Cyl 3 reading fluctuates down to 1.4 mg/str and then back to 2.99 mg/str. I was considering replacing the injector seals and carrying a diesel purge as my next step. Any Ideas would be helpful? Pete
