Ignition system Issue - the bigger picture

Hi I posted this on jeep forum as the discussion on this issue is getting bigger by the day. Looks like many of us are running into this issue now:

I have error code P0673 - Plug 3. I also have the camshaft position sensor code P0340 and HAD P0335 Crank Shaft Position sensor - but it seems to be gone.

I am at 96000km on my 2008 so my bumper to bumper is gone.

I know the glow plugs are maintenance but but was stunned that the dealer wants $417 for the camshaft sensor! The Crankshaft Sensor is $75.

The real reason I brought it in is because there is what I can only describe as a ticking sound coming from the passenger side of the engine near the back of the engine. It is there cold or hot and increases frequency with motor speed. The technician says they can hear it but have no clue what it is.

The service advisor told me to replace the glow plug of course. He also said to replace the crankshaft sensor because it sounds like it is coming from that area... but according to diagrams on other forums the Crankshaft sensor is on the bellhousing on the drivers side of the motor

Ok for CRD owners in S-Ontario here are some facts and numbers i have discovered.

1. Glow Plugs used to be 80+ dollars, they have switched to a new stock and are now $50. But good luck finding them from the dealer, there are 4000 on back order.
2. Good News - Mercedes dealers have them for $41 - some have them in stock, others are special order - 4-6hrs to get them.
3. Bosch plugs are $23 - good luck finding them
4. Beru $31 - some are around - 7 and I got dibs on 6.
5. The camshaft position sensor is $417 from Chrysler, $261 from Mercedes, $175 from parts stores, $32 + shipping online...!!!!
6. I ordered the camshaft position sensor from Family Auto Parts $63 - 3-7 business days delivery...hopefully its the right one.
7. The least expensive crankshaft sensor.... from the dealer $75! (cheaper online but not with shipping.)

8. Does anyone know how to move the wiring harness that blocks access to Glow Plug bank 6 (drivers side firewall) without a. breaking off or b. breaking it off!

9. I have a diagram from the dealer for the cylinders - not sure if it is legal for me to post it?

10. Why is my entire ignition system failing at 96000km!!!!! Honestly love this truck, but already getting the sinking feeling there are alot of 'I dunnos' coming from the dealers and they are going to get to the bottom of this by way of my wallet.

Jeep dealers know almost noting about CRD. Mercedes sprinter dealer is a better choice since sprinter use very same engine

Actually nothing. No hard start (so far) just the annoying noise and a check engine light that wont stay off.

I agree. Called 3 Mercedes dealers in the area - they wont touch it. Found the biggest Dodge Sprinter dealership and they are happy to take a look at it - but of course another 130 diagnostic charge is needed. I am OK with paying that, but not if they find something obvious, its not a warranty item, and that the first dealership didn't find and should have found in the first place.

We will see

Re: Ignition system Issue - the bigger picture

I'm at 114000kms and have not had any of these issues. Wait sorry I lied. I had the ticking sound as well, but it went away. I know what you mean when it comes to the dealership not having a clue. The local one I deal with in Barrie has no damn clue when it comes to issues with my jeep. And another form I'm on that has a lot of merc techs on it tell me to go to certain dealers to get work done, if it's big issues that need to get fixed. If you pm me I will tell you the other forms name and you can post it there, and since it's a local forum for us Ontario guys it works great and the guys can get you pointed in the right direction.
