Hi everyone.
I'm new to the Vag community.
First poster on here.
Bit of a long post bit here we go.
I'm an avid Jap Fan.
Only ever had Japanese cars.
Last week I decided I needed a sensible economical car, got on the local news website. Found an "s-reg" 1999 Audi A4 1.9 tdi for a few quid under a grand.
Rung up, and 2 hours later I was happily driving home in my new sensible motor. She was lovely. Drove well, no issues or knocks, 130k miles on it. 2 owner car, chap had it for 9 years and serviced well and regularly. He just got a brand new a4 so didn't need this one.
My fuel gauge was on quarter of a tank and the display showing 185 miles to go till I needed fuel. 10 miles later the car came to a stop. I pulled over and when I turned the key off and on again to see what was going on the gauge wasn't moving, the display saying 0miles...
I rang the missus and after 10 minutes of laughing at me she brought me a can of diesel. I smelled it before putting it in, it was diesel. I put it in, got the missus turning it over, while I loosened injectors and bled them.
She fired straight up but a very harsh diesel knock associated with it.
Very loud, almost like there was no oil in it, turned it off straight away, checked oil, looked underneath no leaks, all looked fine.
So I fired it up, and drove off. I was a mile from home, the car had no power.
1st, 2nd and 3rd gear is the best I could do, no power in 4th and 5th...
It's almost like the turbo didn't come on at all.
So after endless google searches I had no idea what was going on.
My brother told me to try turning the key to off and on again while driving it. I tried it and whooooo, she came alive, boosted all the way to 3k rpm and died again. So repeat the process, and after 3 days of doing it I came to the conclusion it randomly loses power, sometimes I've got power for 2 sec. sometimes she pulls like a train all the way home, 15 miles....
The harsh knock is still there wether it's got power or not.
I took it to 5garages and a mobile mechanic who is an Audi Specialist came out to see it.
They plugged their computers in it, and all had the same Code.
"---00550 - Start of Injection Regulation
00550 - Start of Injection Regulation: Control Difference
Possible Symptoms
Malfunction Indicator Light (MIL) ON
Loss of Power
Starting Problems
Transmission in Emergency Mode
Possible Causes
Fuel Tank incorrectly filled with Petrol or Biodiesel
Air/Water in Fuel System
Injection Timing incorrect
Electrical Fuel Pump faulty
Possible Solutions
Check Fuel Tank for Petrol and Biodiesel
Drain Tank and Fuel System
Check Fuel System for Air/Water
Check Fuel Supply and Return Lines for Blockage and Leaks
Check Electrical Fuel Pump
Check/Correct Injection Timing
Perform Basic Setting / Use TDI-Graph---"
The mechanics tried everything in the solutions list.
Everyone looked at it puzzled, timings been checked, they bled the injectors time and time and time again.
Got a brand new 3rd injector fitted ( the one with the sensor ).
New diesel filter.
Fuel system blown out and cleaned.
Fuel in it checked ( been filled up with esso diesel )
Someone please help me figure this out.
I ran out of ideas, mechanics hate me.
Please
I just wanted a sensible car.
