Serving Clifton, Franklin, Hawthorne & Newton, NJ, plus Lodi opening soon
KRP Lodi is opening soon.
BMW's U.S. diesels, from the 335d and X5 xDrive35d to the 328d, 535d and X3 xDrive28d, pair big torque with excellent economy. KRP services them across our North Jersey shops.
We handle the full range of diesel work on BMWs: fuel filters and water separators, DEF and emissions systems, DPF and EGR service, injectors, turbochargers, glow plugs, cooling systems and the transmissions behind them. BMW sold diesels in the U.S. from 2009 to 2018, so every one is now out of its original warranty and into the years when independent service makes the most sense.
For the rest of the car, see our BMW page. Here are the diesel-specific issues we see most.
The six-cylinder 35d and 535d, and the four-cylinder 328d and 28d engines.
| What you notice | What it often points to | Where we start |
|---|---|---|
| DEF warning or an emissions fault message | DEF tank heater, pump or NOx sensor faults. | Exhaust system |
| Loss of power or limp mode | A blocked particulate filter, an EGR fault, a boost leak or a turbo actuator. | Diagnostics |
| A rattle from the back of a four-cylinder diesel | The four-cylinder's timing chain sits at the transmission end of the engine, and chain wear is a known issue. | Engine repair |
| Oil leaks | The oil filter housing gasket and valve cover gasket, as on most BMWs. | Engine repair |
| Coolant loss | The EGR cooler or plastic cooling parts. | Cooling system |
| Rough or delayed shifting | Fluid condition in the six- or eight-speed automatic. | Transmission service |
Yes. BMW diesels need an oil approved to BMW's diesel specification. We use the correct approved oil for your engine. See oil changes.
Many owners think so. The engines are strong, and with the emissions system and timing chain looked after, they cover high mileage.
DEF (AdBlue) is injected into the exhaust to reduce NOx emissions. The car warns you before it runs out and limits restarts if it does.
Most repairs at KRP Automotive are guaranteed for as long as you own your vehicle. If you pay for a repair at our shop, you shouldn’t have to pay for it again, that’s our promise at all four open New Jersey locations.
