The best part of owning a high-end luxury vehicle like an Audi is that you’ll get noticed. Your status in society will be elevated to such a point that people in your neighborhood will respect and admire you. But, there is a catch… as with any other vehicle, your Audi is susceptible to different problems- the most notable being the flashing of the check engine light.

So, what can prompt your Audi’s check engine light to start flashing and what could you do to diagnose the issue before it turns into an expensive repair??? Let’s discuss…

Common Reasons Your Check Engine Light May Be On

Being a part of your Audi’s onboard diagnostic system, the check engine light essentially comes on when a glitch is detected by the onboard computer in one of the crucial parts of the powertrain system or in the emissions control system. What kind of glitch, you asked? Well, let’s find out…

#1- Oxygen sensor failure

Mounted on the exhaust pipe, the oxygen sensor measures the concentration of oxygen gas in the exhaust emission. This real-time measurement of oxygen concentration, in turn, helps the engine control unit or ECU in keeping the air-to-fuel ratio inside the cylinder balanced. Should a sensor of such significance fail, the engine will perform poorly. This can lead to the illumination of check engine light.

#2- Catalytic converter issue

The catalytic converter is entrusted with a very simple task- which is to treat the exhaust emission before releasing it to the environment. This after-treatment device is the reason why your Audi meet emission regulations. If it fails, you will have to deal with all sorts of drivability issues. And, yes… you may even end up with a flashing check engine light.

#3- Defective MAF sensor

Just like there are sensors in place to monitor exhaust emissions, there is a set up to track and regulate air flow into the engine. Placed between the throttle body and air filter, the Mass Air Flow sensor is an important part of that arrangement. The data provided by this sensor helps the ECU in keeping the air-to-fuel proportion inside the combustion chamber close to ideal. A glitch in a sensor of such significance may set off your Audi’s check engine light.

#4- Loose gas cap

Another notable explanation as to why your Audi’s check engine light may start flashing is a loose gas cap. For those who don’t know, the gas cap is an important part of a vehicle’s evaporative emissions control system. And, the onboard diagnostic system of your Audi is programmed to warn you by setting off the check engine light- should something unusual happen to the gas cap.

Illuminated Check Engine Light: Resetting Tips

You may end up with expensive repairs if you decide to ignore such a warning indicator. So, you better try to figure out what went wrong with your Audi that set off the check engine light and have it fixed ASAP. Listed below are a few steps that you can follow to reset your Audi’s check engine light.

#1- Retrieve trouble codes

Use an OBD-II scanner to retrieve the trouble code stored in the fault memory of your Audi. The code will reveal a lot about the nature of the issue you are dealing with and may even help you reset the light. In addition to the use of OBD-II scanner, there are many different methods that you can make use of to reset the light.

#2- Contact a professional

If you are not handy with tools, you should take your Audi to a reliable service center in your locality to get the issue diagnosed. Professionals working in the service center are well equipped to deal with such issues. After thorough inspection, they will able to tell you the exact reason that prompted the onboard diagnostic system to activate the check engine light.

Hellertown’s Go-To Shop For Fixing BMW High Pressure Fuel Pump Failure

by Chris Limantour | Mar 2, 2024 | BMW Repair

Of late, have you been battling a stalling issue when driving your BMW??? From a carbon fouled spark plug to a clogged fuel injector; there are all sorts of reasons why your engine may behave this way. High pressure fuel pump (HPFP) failure is one possibility. Yup, you read that right… a glitch in your BMW’s HPFP may contribute to repeated stalling. Some of the other common complications that you might have to deal with if your vehicle’s HPFP gives up have been discussed below.

BMW High Pressure Fuel Pump Malfunction: Discussing Complications

Being a key component of your BMW’s fuel system, HPFP is entrusted with a very simple task… which is to deliver pressurized fuel (2,200 to 3,000 PSI) to the injectors. It is because of this part that your BMW engine operates with such a high efficiency. Should this device give up, you will encounter all sorts of drivability problems.

#1- No-start issue

Reviving your BMW engine won’t be an easy task if there is something off with its HPFP. Fuel, air, and electric sparks: these are three ingredients that an internal combustion engine need to start the combustion process so that mechanical torque can be produced. If the HPFP is defective, the engine won’t get enough fuel to initiate the ignition process.

#2- Engine misfire

This is yet another major issue that you might have to deal with because of a defective HPFP. Engine misfire can be defined as a condition when one of the cylinders doesn’t fire the way it is supposed to. Some of the hurdles that may contribute to engine misfire in a BMW include a worn spark plug, a damaged fuel injector, a malfunction in the air-intake system, and yes… a defective HPFP.

#3- Sudden power loss while driving

Off late, has your BMW been struggling to run at a steady speed??? If so, there is a good chance that its HPFP has given up. HPFP is the reason why your car engine gets all the fuel it need to provide you with the requisite torque. If the engine doesn’t receive the necessary amount of fuel because of a defective HPFP or any other reason, your BMW will have a hard time operating at a steady speed.

#4- Increased fuel consumption

Are you getting poor gas mileage? As strange as it may seem, a defective HPFP may prompt your BMW to burn fuel at an alarming rate. The issue will only get worse over time. So, if you don’t want this unexpected drop in your BMW’s gas mileage, ensure the upkeep of its fuel pump.

Leading Causes Of High Pressure Fuel Pump Failure In BMW Cars

#1- Mechanical damage

The HPFP your BMW comes fitted with is a very complicated device made up of many different parts including a pressure spring, pressure control valve, coil body, oil seal, mounting flange, roller tappet, etc… If for some reason the pressure control valve acts up or the pressure spring gets damaged, the HPFP’s ability to provide pressurized fuel to the injectors will drastically reduce.

#2- Contaminants

This is yet another leading reason behind HPFP failure in BMW cars. Being a mechanical device made of numerous metallic parts of different shapes and sizes, HPFP can malfunction if gets exposed to contaminants. Fortunately, there are many different things that you can do to safeguard your vehicle’s HPFP against foreign elements.

#3- Lack of lubrication

Not using the right type of lubricant, as recommended by the manufacturer, can also result in premature HPFP failure in a BMW car. It is therefore important that you check on your vehicle’s lubricants from time to time and make sure that the engine and other important parts of your BMW never run low on lubricant.
