OM606 Glow Plugs Again??

[treetops]

Hey all,

So I replaced all 6 GPs on my E300 in March of last year and now my GP and CEL are lit up, so one or more is out. This does not sound or feel right to me.

Now, I have been using the car for work which is about 6-8 stop/starts, sometimes more, per day with the engine stopped for anywhere from 20 mins to 2 hours. My crude math calculates thats about 2200, or more, starts/glow cycles since 3/15 assuming the GPs cycle on hot starts as well.

I used Bosch DuraTerm GPs and according to thier tech sheet says overheating due to controller failure is the leading cause. Continual cycling, which given my use of the car maybe the case, is listed too. BTW, these GPs are designed for a 3 min after glow as well.

Im not sure if the OBD/CAN would throw a CEL for a controller failure but I am sure my driving use of the car is a factor here.

Any thoughts or do these GPs just die after a certain # of cycles. Not looking forward to doing this again.
