Good morning everyone I went to the workshop for a problem on this car :

opel astra j year 12/2009 kw 92 engine designation a17dtr

the glow plug light came on

replaced the old BERU glow plugs with new BERU glow plugs but the problem recurred

they replaced the glow plug control unit but nothing was solved

I replaced the glow plugs with NGK brand because such a problem had already happened to me

the car after one month works fine and the warning light has not come on anymore

Good work to all

Claudio
