Ck Engine/P380/Glow Plug Circuit

When I ohm'd the glow plugs as the forum suggested I had one glow plug that had a very high reading and needs to be replaced. How do I know if they are Bosch or Beru? Should I replace all 4?

If you actually found one flakey, then I would let the harness go for now and just replace the plugs...but often times it is the harness at fault.

Same problem with mine. One plug faulty. Replaced all 4 glow plugs. Did not replace the harness. Remove code from ECU and be happy. CEL has been off ever since.

If the car is more than a couple of years old or has more than perhaps 50,000 km on it, I would replace all of them if I were you.

Thanks, should I replace the glow plug wiring harness as well?
