Coastal driving is hard on a modern diesel in a way most owners don't expect. Short hops between Leucadia and the freeway rarely get the exhaust hot enough for the particulate filter to clean itself, so soot builds up, the computer asks for a regeneration it can't finish, and the truck drops into reduced power. Injectors, glow plugs, and DEF add more to watch.

- The computer is protecting the engine, usually over an emissions, boost, or sensor fault.
- Slow to fire on a cold morning
- Glow plugs, the glow plug relay or module, or weak batteries.
- Smoke you didn't see before
- Black points to fueling or boost, white to unburned fuel or coolant, blue to oil.
- DEF warning or countdown
- A heater, pump, sensor, or fluid quality problem in the DEF system.
- Fuel mileage falling off
- Injector wear, a dragging regeneration cycle, or a restricted air or fuel filter.

You approve

Frequently asked questions
Why does my diesel keep asking for a regeneration?
Usually because it isn't driven long enough at highway speed for the particulate filter to burn off soot. A sensor or EGR fault can also cause it. We check which before recommending anything.
Is limp mode safe to drive in?
It's meant to get you somewhere slowly. Drive gently to the shop if it feels safe; if not, call us and we'll arrange the nearest tow truck. Towing is billed by the tow company.
Do you work on diesel cars as well as trucks?
Yes. Pickups, vans, SUVs, and diesel cars such as Volkswagen TDI and Mercedes-Benz BlueTEC models. Call with your year, make, and engine.
Does my diesel need a smog check?
It depends on the vehicle. See our STAR smog check page or call us, and we'll tell you whether we can test it here.
What if I bring my own injectors or parts?
We can install parts you supply. Customer-supplied parts carry no warranty, parts or labor. We normally install our own high-quality parts.
How can I pay?
Cash, major credit and debit cards, Apple Pay and Google Pay are all welcome here. Ask about current coupons.
