Glow plug replacement for your Sprinter clears hard cold starts, rough idle, and a glow plug warning light that can sideline a Riverside delivery van. We test each plug and its control module with Xentry, then replace the failed OM642 or OM651 units, working seized plugs loose carefully so the cylinder head threads stay intact. Most vans leave starting cleanly the same day.


## What this includes
- Xentry test of each glow plug and the glow control module
- Resistance and current readings to pinpoint the failed plugs
- Careful removal of seized plugs to protect the cylinder head threads
- Genuine glow plugs torqued to Mercedes spec
- Glow control module replacement when the module is the fault
- Cold-start check and fault memory clear
- Report on any plug that broke, with thread repair if needed

## Who it is for
- Your Sprinter cranks longer than usual on cool Riverside mornings
- A glow plug or check-engine light is on
- The engine idles rough and smokes at start-up
- One or more cylinders misfire until the engine warms

## Pricing
Mechanical labor runs $260 per hour; seized plugs and a faulty glow module push the range higher, all set in writing after inspection.

## FAQ
### How do I know a glow plug has failed?
Typical signs are hard cold starts, white smoke at start-up, rough idle until warm, and a glow plug or check-engine light. We confirm with a Xentry resistance and current test on each plug.

### Do all the glow plugs need replacing at once?
Not always, but on a high-mileage fleet van we often suggest a full set, since the remaining plugs are usually close behind and a single visit saves paying the shared labor twice.

### What if a glow plug breaks during removal?
Broken plugs happen on carboned diesels. We use the proper extraction tools and thread repair when needed, and we tell you before any added work changes the cost.

### Will this fix my rough cold idle?
If failed plugs are the cause, yes. We verify with Xentry first so you are not paying for plugs when the real fault sits elsewhere.
