An Ounce Of Prevention – Antifreeze and Coolant Service

The Importance Of Antifreeze/Coolant Service Take a look at these photos, notice the brown areas of clogging and material at the bottom of the radiator? Nowhere is this more frequent than on engines using an aluminum cylinder head, and cast iron block…like most modern cars. And we also find this clogging not just in radiators, but also in heater cores. A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core. Fins attached to the core tubes serve to increase surface for heat transfer [...]

Car Batteries – Facts About Lead Acid Or AGM Types

Why AGM Batteries? Absorbent Glass Mat batteries (AGM) have been a market favorite for the past decade for reasons of capacity and durability. These batteries are becoming much more common in European and imported autos like Audi, BMW, Mercedes, Mini Cooper, Volvo. How They Work In principle, the AGM batteries work like any other lead battery. However, the AGM batteries, compared to flooded batteries, have several significant improvements that make them more efficient.

Land Rover Evoque – Engine Problem With Timing Chain Sprocket

The Problem This Land Rover client presented us with a 2015 Evoque with a Check Engine Light (CEL) on, and noise from the engine. On inspection, our Land Rover technician verified that the CEL on, and carried out a visual assessment. Then using the diagnostic computer we checked and scanned for codes. We found the following fault codes, P052A - Cold start camshaft timing over advanced bank 1, P0011 - Intake camshaft position timing over advanced bank 1, P0341 - Camshaft position sensor A circuit/range performance bank 1. Fault codes are only a starting point, we never use them for component [...]

BMW and Mercedes Benz – Ceramic and Aluminum Fuse Problems – How and Why

About The Problem One of the more common electrical issues we see with the vintage Mercedes vehicles are problems related to the fuses and fuse box. Like many of the older European models, these cars were designed and engineered with identical or similar parts, in this case, the ceramic and aluminum exposed fuses. At the time, this was an excellent solution, but now, some 20 years later, we frequently see a series of pattern failures on vintage Mercedes, and almost always the same issue over time: fuse failure. While the ceramic and aluminum fuse failure is particular to older European vehicles; however, it’s a simple problem to fix in [...]

Mercedes Benz Intake Manifold Problem Explained, And How To Correct It

Many owners of late-model Mercedes-Benz cars equipped with 3.0 and 3.5l V6 engines (M272 or M273), as well as some of the later V8s, have or will likely soon experience a near-universal Mercedes Benz intake manifold problem.  Generally, we find problems in performance, which include poor idle, loss of power, and a Check Engine Light. The Mercedes Benz intake manifold problem is caused by one of the inlet manifold tuning flaps breaking, causing unexpected and deficient performance depending on the orientation of the flap that has broken.  To review the system, let's describe what the Mercedes intake system is doing and why variable-intake-runner intake manifolds are becoming such [...]

Evaporative Emission (EVAP) Faults – Check Engine Leaks

Evap System The evolution of evaporative emissions systems has been driven by changes in emissions standards. While some vehicle manufacturers have introduced very different designs along the way, most use primarily used a vacuum-based design as a foundation. The exceptions are its hybrid electric vehicles, which use an evaporative leak check monitor (ELCM) similar to the Toyota key-off vacuum pump system, and 2011-03 Ford Fiestas, which use a natural vacuum leak detection (NVLD) system similar to the one used by Kia and BMW. What is It The oil and fuel in your vehicle give off vapors that are very [...]

Tire Pressure Warning Light (TPMS) Light Coming On in Cold Weather? Here’s Why

TPMS Light On TPMS Light Coming On in Cold Weather? Here’s Why! If your TPMS (tire pressure monitoring system) warning light goes on during a cold snap, it may not mean your tire has a leak. Fun Fact Tire pressure can decrease about 1 PSI (pound per square inch) for every 10 degrees the temperature drops. It's not that more air is escaping your tires, but rather the air inside the tire condenses, taking up less space when it's cold. It's similar to how a cake, just out of the oven, flattens out a bit as it cools. [...]

Tire Wear – Tire Cupping, Causes and Correction

What Does Cupping Look Like? Tire cupping is an uneven wear pattern, which occurs due to irregular up-and-down motions of a wheel (bouncing). It interferes with the proper contact of the tire with the road, scooping rubber in spots. When it comes to your tires, cupping is a bad sign and typically means you have other problems with your car that are affecting your tires. The term “tire cupping” is unfamiliar to many drivers, but it’s a problem that happens more frequently than you’d think. Cupping, also known as tire scalloping, refers to when a car or truck’s tire tread [...]
