Hi, I ordered one from Beru itself, the GSE114. The one I had installed was Mercedes, 642 900 58 01.
Both only give 1.6 Volt to all plugs.
When I keep on preheating for about 10 seconds (while light is already out) it starts perfectly normal!
Temperature is about 12°C in the morning.
My problem is on a W211 320cdi V6 (2008) for which I don't find a solution in the existing treats.
In the morning, the car will not start immediately, but when you preheat 3 or 4 times before starting, it starts without any problem.
Because the glow plug controller is a common...
