Good morning I went to a garage because they had a problem with a Panda 1100 mpi year 2002 still old model that every now and then it would turn off without warning and in any condition it passed through several garages and they replaced the engine control unit injectors group electric wiring harness starter panel with code control unit but after this the problem was not solved I remained in the garage all afternoon and in fact the car every now and then turned off and did not give an error code if you tried to restart it it would not know about it only if you unplugged the connector that goes to the control unit it would start so I had a control unit that was disturbed and this is the big one positioned on the front of the car. If you tried to restart the car it wouldn't start, only if you unplugged the connector that goes to the control unit it would start, so I had the control unit that was being disturbed, and this is the big one located on the mudguard I went to the shop and got 4 spark plugs and a set of cables I took the spark plugs apart and couldn't work out what brand they were. After this replacement the car has now been 7 months and the problem has not occurred.

Good Work
