Video tutorial

In this video we see a Panda with a LPG system in which the engine light only comes on when running on LPG, while it immediately goes off when running on petrol. The diagnosis is done through the EOBD port and the error code P1172 is read, indicating a problem with the air/fuel mixture being too rich.

The causes can be various: faulty or dirty injectors; too high fuel pressure; faulty fuel regulator; dirty or clogged air filter; faulty MAF sensor; leaks in the intake or exhaust system. Since it is a vehicle with dual fuel system, the main problem could be the LPG injectors, and indeed after replacing them the problem is solved.
