Flushing of direct injection injectors without removing TFSI Audi A6 C7 with LAVR ML101 flushing
The purpose of cleaning the injectors is just for prevention.
Car #Audi A6 C7 engine 2.0 TFSI GEN2 CDNB 180L.s.
According to the results after washing:
fuel consumption has decreased slightly, I think within the margin of error
fuel correction improved, was +5-6%, after cleaning +2-4%
the average injection time has practically not changed, at idle about 0.4 ms
the coking effect on the pistons is not noticeable
============================
Timecodes:
0:00 Start
0:19 Fuel pump fuse
1:31 Connection of the nozzle flushing station
4:28 Engine running on nozzle cleaning fluid
8:17 Condition of spark plugs after flushing
8:34 Checking pistons with an endoscope
9:50 Results after flushing the injectors
11:49 Fuel correction before and after flushing
============================
Procedure of action:
warm up the engine to operating temperature
pull out fuse No. 2 at 25A (when the engine is stopped)
start the engine to generate fuel in the main line
connect the flushing station to the injection pump fitting
pump the pump /compressor to a pressure of 3-3.5 bar, make sure there are no leaks
start the engine and let it idle for about 15 minutes, watch the pressure drop, sometimes pump up
stop the engine and wait 15 minutes
start the engine again and increase the rpm to 1500-2500
after the entire liter of cleaner is used up, insert the fuse of the fuel pump and start the engine on gasoline, let it work for 15 minutes, but better even more, erase the errors
after leaving, not to gain much momentum, I had a detonation at speeds above 2000, after 10 km everything returned to normal
====================================
Recommendations:
it is better to take a better fuel filter. During the 3 bar pressure supply, the filter "inflates", does not inspire confidence
thread on the 1/4 fitting, you can buy it for a hose or for a quick-release connection, if there is a compressor. I bought an 8mm hose
additionally buy a fuel hose and several 10-12mm clamps
