I need some assistance with a problem I am having with my Audi
A4 2.0TDI B7 2008 BLB
Bought cash 2nd Hand 2018 - WeBuyCars Midstream - AS IS - R65000.00
Full Service record - Rustenberg
No warranty
NO ASSISTANCE from Audi even with the car full service history
Drove this car like 8 months without any problem.
Long Story short, Jerking when accelerating.
When Hot the car is jerking when accelerating
Now it's after starting the car, Cold or Hot jerking when accelerating
If driving more than 10km it's a nightmare
4 months ago it started, filled the car with diesel, and the next morning it was jerking when driving around town, now I was told it
is dirty injectors, so I went with New Diesel filter, so I also bought injector cleaner.
What I did.
Diesel Filter with T piece / R400
Wynns Injector & Turbo Cleaner / Full Tank / R90 + Diesel
Wynns Dry Fuel / Full Tank Again / R90 + Diesel
Injector Purge / R800 later
The same did not solve anything.
After I had the car at 3 Mechanics and Audi in Welkom they all said it's injectors. R13000 each Goldwagen Prices !
Diagnosed the car with code reader, and there was a open circuit on injector bank 1 / R2800 to repair quote
Open circuit was the wire connector that was lose / Costed me R1200 at garage from friend
Injectors Tested, Injectors were 100% fine on test but I Re-conned them by Diesel Bosch Welkom R3200 each R12800.00
Problem still the same
Now Mechanics at Audi Welkom said it's either one of these
Went with Goldwagen Price
Fuel Lift Pump - Replaced R9000 Audi / R1200 Goldwagen
Fuel / Vaccuum Pump - Replaced / R25000 Audi / R4500 Goldwagen
EGR Valve Tested and Cleaned / Replaced with EGR Delete Kit / R500 job
Removed Cats / Then Strait Piped it / R1500 Best Drive Welkom
O2 Sensor replaced now it's replaced with a dummy for the check engine light R200 Best Drive Welkom
Problem is still there
Cam Sensor / Speed Control Censor Replaced / R650 Goldwagen did it myself as Audi wants to book in car, and R5500 later
Problem still there
MAF Sensor replaced R800
Turbo Censor replaced R450
Boost Pipes checked for leakes or cracks R0.00
Turbo Cleaned and turbo actuator replaced R750
Took off the manifold and cleaned it, also replaced all manifold caskets R200 for caskets
Also I now did a full service with new Diesel filter, fuel pipes, cleaned the tank, Glow plugs, lift pump fuse, main fuse, all car fuses, and fuel pipes changed / R3500 job
Checked the ECU for Water damage and tested ECU at Audi / R1200 to test it neh
No fault codes appear and no engine lights come on at all and still nothing / R450 for diagnostics done
ECU Reprogrammed with Stage 1 Soft Mod from Revo, remap I think they call it that, R3500
Went back to Diesel Bosch Welkom, they did test again, nothing wrong. R250 each to test
------------------
Spend around R30k on repairs and getting no were.
Every person that tries to help me is saying it's the injectors
I am left with 2x options now
Top gasket (No burning oil, and no boiling water or using water, temps is normal even if driving out of town 200km trips) R5000 - R7000
Turbo (Spins freely, and no play, No smoke) R9500 Turbo and if I import it R6000, then to fit R2000 ?
Turbo is a GT1749v also a GTA1749 will work
Clutch is not slipping, but can it be clutch causing all this nonsense R6000 - R8000
No engine or gearbox mountings broken
No leaks like oil, or main gear seal leak
No Vacuum leaks
No smoke when driving
No misfire on idle
Still drives, jerks on low rpm and there seems to be boost and now and then low boost, but it's there, high rpm it's fine, but then it's driving it like you stole it.
Not sure what the actual fuck is it with this car. Anyone maybe know what it can be, or know a place or someone that can fix it.
