BMW, Mini Cooper “Lifetime Fluid”
There is a trend with many manufacturers to use so called “Lifetime” transmission fluids in their new cars. Audi, BMW and Mercedes have been doing this for years.
Tech Tip – Registering New Battery on BMW and Mini Cooper
Did you know that the BMW engine computer, known as a DME (Digital Motor Electronics) must be programed to know a new battery has been installed?
Our Senior Service Technician Nick explains why. We’re obviously playing up the humor here, but the topic isn’t a joke, it’s a real issue.
Otherwise the battery can under or overcharge, and cause premature battery failure. Older batteries become sulfated with time and require a higher charging rate. So unless the DME is notified a new […]
AMC Tech Tip – Low Tire Pressure Warning Lights In Cold Weather
As winter approaches, many motorists will experience a low-pressure warning light on the dash or simply observe that the tires look a bit less full than they should. The main reason for this is the dropping temperatures, which cause the air to become denser and consequently lower the tire pressure. Of course, tires naturally lose pressure over time, or there can be a puncture.
Tire pressure monitoring systems (TPMS) are a real boon to safety and convenience, and they have been required […]
Just had a customer contact me this morning about the purchase of a used BMW from a private seller. The price sounded too good to be true…until I heard the rest of the story. Seems it needs a “few things” – “It idles up-and-down and will even stall. It could be a mass airflow sensor, oxygen sensor, or something similar.”
Yikes, right? Might be a bargain, or might be real headache, but you don’t know until you have the car looked at professionally. As our Service Manager Rick likes to say “The […]
The electrical system in late-model Minis and BMWs is quite sophisticated, in that it tailors charging as closely as possible to both the type and age of the battery. The Engine Management computer also controls the alternator output. When replacing a battery, this computer needs to be informed if you’ve replaced the battery or updated the vehicle from a conventional Lead Acid battery to an Absorbent Glass Mat (AGM) type; it charges the AGM differently than a traditional battery.
How It’s Done
This process of updating the alternator-control computer is called Battery Registration. Ignoring […]
A common yet avoidable problem we see with BMW and Mini Coopers is turbocharger failure. Turbocharger failures can be catastrophic, so they are important to address at the first sign of a problem. As its name implies, a turbocharger is a device increases the power output of an engine.
In our workshop, we see a number of turbocharger or “turbo” issues, on a number of different cars. Almost always on vehicles not serviced by us, but rather referred to workshop by the dealer, or another repair facility. Over the years we’ve compiled a very effective set of diagnostic principles to make the determination of […]
If you own a 2007-2010 Mini Cooper S over 30,000 miles on the odometer, you’ve likely paid to have the timing chain system, or perhaps even the engine, repaired or replaced.
* Important – We literally receive hundreds of phone calls per year on this issue. Please note that unless you are a service customer of AMC, or live in the state of Maine, or are willing to transport your Mini Cooper here for service, we can not answer questions about out of state vehicles, and would refer you to the the local Mini Cooper dealer in your state for assistance. If you are a current customer […]
– Mini Cooper Timing Chain Service –
New kit installed
Big Nick hard at work doing a timing chain update in a newer Mini Cooper.
Be it a Cooper, Cooper S, or Clubman, we see this nearly weekly on the Mini Coopers in our area. You can read all about Mini timing chains at our Mini Timing Chain 101 page – http://tinyurl.com/Happy-Mini
Fortunately this was caught BEFORE it failed and damaged the engine. When looking at the R56 Mini Coopers (2007 and newer) , we’d always advise checking to see if the […]
Problem occurs with both “S” and non “S” models
Carbon Deposits On Intake Valves
As the largest Mini Cooper service specialists in Maine, at the Atlantic Motorcar Center we’ve noted a significant increase in late model Mini Coopers with cold start or cold running problems, even to the point of stalling, or Check Engine warning lights coming on.
We’ve found that many of these Mini Cooper direct injection engines suffer from an excessive carbon build up on the back of the engine intake valves. The carbon build up […]
Low Washer Fluid Warning
Have you experienced a washer low level light that seems to stay on all the time, or worse yet, doesn’t come on at all, even when the fluid is low or empty? This is something we are seeing more and more often, now that the New England snows have finally left us, problems with the fluid level sensors in customer car’s washer solvent bottles. The problem seems to occur across the car lines we service, and doesn’t seem to matter what kind of car, we’ve […]
