Volkswagen Tech Tip: DTC P0401, Followed By P2463, Due To High Soot Loads Before Regeneration Cycle
The car owner may complain that the MIL light is on. When the codes are scanned, code P0401 Exhaust Gas Recirculation Flow Insufficient and P2463 DPF Soot Accumulation will be stored in the ECM.
VANOS BMW: Variable Valve Timing Diagnostics
Diagnosing a VANOS system does not require that you speak German. What it does demand, however, is knowledge of how the actuator adjusts the camshaft, how the solenoid controls the actuator and when the engine control module changes camshaft timing. As for tools, you will need the appropriate tool set to lock the crank and camshaft. You will also need a scan tool and a scope to observe the crankshaft and camshaft signals to accomplish more advanced diagnostics.
Alternator Testing Diagnostics Are Getting More Complicated
One test is not enough if you are diagnosing a charging system problem. All too often, if only battery voltage is present with the engine running the alternator is condemned as the source of the problem. If this is the case, it means that the alternator is not charging, but does not reveal why.
Getting The Big Squeeze: How Mazda’s New Spark-Controlled Compression Ignition Engine Runs Long On Fuel, Short On Emissions
Until Mazda recently introduced its new Spark-Controlled Compression Ignition (SpCCI) gasoline engine, internal combustion engines (ICEs) were classified as either spark or compression ignition. The historical differences between the two were obvious: spark-ignition engines were quiet and smooth and compression-ignition engines were not.

Pinpointing Oil Consumption Issues: Now You See It, Now You Don’t
Oil consumption has become an issue because oil change intervals now extend to 10,000 or more miles and because modern engines consume so little oil that many vehicle owners forget to regularly check their engine’s oil level. Worse still, many owners will often run their engines out of oil because they don’t know how to check the oil level. For that reason, oil level warning systems are becoming standard equipment for many vehicles.
Head Gasket FAQs
Replacing a head gasket is a significant investment for the customer. It also represents significant risk for a shop if the replacement gasket fails. To do the job right, you have to ask why the gasket failed in the first place and what it will take to prevent it from happening again.
Variable Valve Timing Diagnostics: 2009 Murano Case Study
It was a scenario to which we can all relate. A long-time customer passed away and his vehicle was being gifted to his granddaughter. The 2009 Murano was dropped off by the grandmother, who asked us to give the car a really good look over since she didn’t want the granddaughter to have any problems or expenses with the gift.
