I have a very serious problem with my twingo gt (1.200cc turbo,2010), it drives me crazy…..I am thinking about selling it because I do not know what else I can do….(I don’t want to sell it because I love it , and I have make some changes and now I love it more )
The last year my cars fuel consumption is extraordinary ! I change oil every 2000Km because are black and smell gas!!
There is no Warning light comes up, and at Renault dealership they can find any problem.They told my that the Renault diagnostic says everything is ok…
I have change :
1st oxygen sensor new original (the first one before cat)
New spark plugs Original Renault –Ngk
New ignition Coil (original)
New Spark plug wires (original)
New water temperature sensor
New thermostat
New air temperature sensor
New Turbo
New Cat
I borrowed from a friend with the same car to test :
An ECU (used)
MAP sensor (used)
Fuel pump (used)
I have also do the big service and change timing belt and make sure that the timing is correct
I have also make a valve adjustment just in case.
I make a compression test and all cylinders have the same compression and Renault mechanic says that is perfect .
I have done injector flow test at Renault and repeat the test again at another garage , both said that injectors are fine.
I have no oil spot at water and no water spots at oil.
No smoke from exhaust at normal driving only when I hit the rev limiter……
Any Ideas? I do not know what to do…The only things I have not change is fuel injectors and throttle body but throttle ….Injectors have been tested twice , and throttle body through Renault Clip seems to work just fine.. Please help me I have freaked out.
