Diesel Exhaust Fluid / Adblue / Start Counter

With the advent of tougher emissions standards, came the AdBlue DEF system on Mercedes diesels, and a whole new challenge to the owner has been added.

If you have a start counter or countdown on your Mercedes, we can help.

DEF is used along with Selective Catalytic Reaction SCR to lower emissions of Oxides of Nitrogen NOx.

The AdBlue system has a tank, pump, warmer, injection system and a NOx sensor. Everyone of those parts has been known to fail, and we not only know how to repair them, we know how to diagnose and test the system, as well as reset the countdown of starts left before you are locked out from driving your Mercedes.

Our factory Xentry diagnostic scan tool allows us to clear and reset the start countdown after repairs.

Never allow your DEF AdBlue system to run low for long as the pump and heater seem to fail when the fluid runs low. Stop by and see us or give us a call at 604-530-9394 with any concerns you may have.

We also offer Malone Tuning systems to eliminate failures, boost performance and improve reliability for off road use.

Check Engine Light

An ML or GL that has a “Check Engine Light” on or has gone into “Limp Mode” can be a very frustrating thing. The check engine light is illuminated any time the powertrain control module sees something out of its normal operating range.

Frequent causes of a check engine light in a Sprinter Van are glow plug problems, temperature sensors, turbo, EGR valves, boost hose, swirl valves or air charge cooler failures.

Having the right equipment to test the systems and pinpoint the cause of failure is vital, as the cost of replacing the wrong part on a Sprinter Van, can be substantial.

Precision Auto Service in Langley, is one of the only shop in the Fraser Valley to have the Mercedes factory diagnostic tools to accurately diagnose the Check Engine Light or limp mode concerns.

Resonator

Many Mercedes diesels suffer from blown intake and turbo air tubes and broken resonators. Typical symptoms of a blown tube or broken resonator are a loud hissing noise and lack of engine performance when accelerating, often accompanied by the orange check engine light on.

The V6 or OM642 engine has a problem prone design, and while no upgrades piece is commonly available, we do keep them in stock for fast turn around times.

Glow plug

A Glow Plug warning light illuminated on the dash of any diesel is quite common, although the repair requirements can be quite different.

The V6 diesel powered Mercedes ooccasionally have failed modules, but frequently are found to have the Glow Plug stuck, or broken off in the cylinder head.

We have the special tools to both diagnose and repair Sprinter Van glow plugs, but also to extract broken glow plugs from both engines.

EGR Valve

The EGR valve on the Mercedes Diesel OM642 is known to be problematic.

Many V6 models seem to experience failures at very low millage, but many of those problems have been addressed by a re-calibration of the engine computers operating software. Mercedes Benz Canada has also extended the EGR Valve warranty to 10 Years or 194,000 KM’s.

There are so many items that can turn your Check Engine Light on and many symptoms feel similar, give us a call to discuss your vans needs.

Regardless of what symptoms you have, Precision Auto can help you make the most of your engine with a few services to prevent premature EGR valve failure, give us a call at 604-530-9394 for more info.

Limp Mode

An engine that has gone into “Limp Mode” can be a very frustrating thing. The limp home mode is activated as a way of protecting the engine when the powertrain control module has determined there is a problem that may be damaging to the engine.

Frequent causes of limp mode in a diesel are EGR Valves, turbo, boost hose, swirl valve or air charge cooler failures.

Having the right equipment to test the systems and pinpoint the cause of failure is vital as the cost of replacing the wrong part on a Sprinter Van, can be substantial.

Turbo

A Mercedes Diesel that has a failing turbo charger and frequently goes into “Limp mode” can drive you crazy, one moment it is performing just fine and the next it has run out of power.

Having the right equipment to test the systems and pinpoint the cause of failure is vital as the cost of replacing the turbocharger on an engine, can be substantial.

Transmission

A failing transmission can be recognized a few ways, and sometimes it doesn’t require removing the transmission at all to repair your concern.
