BMW, Audi and Volvo Torque Converter Problems

By | January 31st, 2017|Case Studies|Comments Off on BMW, Audi and Volvo Torque Converter Problems

Problem
In our workshop, we see a number of transmission issues, on a number of different cars, from BMW, Audi, Volvo, and Honda. 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 the failure mode, and corrective action, very straightforward.

The old bromide that “An ounce of prevention is worth a pound of cure” never rang truer than in the case of the automatic transmission. Proper […]

The Measure Of A Workshop – Or How To Find A New Home For Your Car

By | March 3rd, 2016|Case Studies|Comments Off on The Measure Of A Workshop – Or How To Find A New Home For Your Car

To Start
For sometime now I’ve been involved with other shops, either in a consulting, or in an industry 20 Group. Over the years I’ve developed a set of criteria that I’ve shared with friends and family about how to properly evaluate where to obtain high quality, ethical auto service. These apply if your auto is an Audi, BMW, Mercedes, Lexus, Saab, Volvo or VW.

Some of these items may seem basic, even commonsense, but all too often folks make the decision of where to take the car under duress, you want to have an ongoing relationship with shop before problems occur, […]

BMW Sunroof Repair and Reseal – Wind, Water Leak and Noise

By | February 3rd, 2016|Case Studies|Comments Off on BMW Sunroof Repair and Reseal – Wind, Water Leak and Noise

Problem

Correction and repair of water and wind leaks. Correction and repair of water and wind leaks.

This BMW 5 series presented with a concern of sunroof wind noise, and a possible water leak or entry. A quick inspection of the existing seal showed that it had become compressed, not an unusual occurrence for a tubular rubber product after time, much like an engine’s gaskets can get hardened and leak, so the rubber seal on the sunroof, installed back when the car was first manufactured, needed service.

Correction
The Atlantic Motorcar Center has developed a very through […]

BMW Water Pump Failure – How, Why, and What To Prevent

By | January 18th, 2016|Case Studies|Comments Off on BMW Water Pump Failure – How, Why, and What To Prevent

What

This BMW 540 has was diagnosed with a defective engine coolant pump. Symptoms were overheating and damaged drive belt system. Disassembly of the front cover and removal of the water pump allowed for inspection of the pump.

How
The mode of failure with this pump appears to be simple age and miles, likely exasperated by a lack of coolant changes. The bearing failed on the pump, allowing the plastic impeller to contact the aluminum housing, you can see the growing on the surface. Finally the plastic impeller itself failed, the vehicle overheated, and came […]

Note sludge or clogging in ventilation port

BMW Service with N52 Engine – This vehicle came from another shop with an uncorrected engine oil leak and high oil use. Consumption was on the order of 1 quart per 100 miles, yes, you read that right.

We started by finding the incorrect engine oil fill cap had been installed by the previous facility, causing an oil leak on the top of the engine, but that was only one problem. The real culprit was a problem with the crankcase […]

By | December 22nd, 2015|Case Studies|Comments Off on Mini Cooper – Engine Problem – Carbon Deposits On Intake Valves

Problem occurs with both "S" and non "S" models 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 […]

The Problem
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 […]

BMW X3 Engine Oil Pan Leaks – The Tao Of Repair and Satisfaction

By | April 13th, 2015|Case Studies|Comments Off on BMW X3 Engine Oil Pan Leaks – The Tao Of Repair and Satisfaction

The Tao
With Atlantic Motorcar’s BMW service team – The word “Tao” is a Chinese concept signifying ‘way’, ‘path’, ‘route’, or sometimes more loosely, ‘doctrine’ or ‘principle’. We’re happy to share information on BMW service, because we know an informed customer is a happy customer, and freely share with other shops as “a rising tide lifts all boats”.

We  title this such to illustrate a point, yes, this is not a simple repair, yes, but one, if done correctly, will last another 100,000 miles. That’s our goal with BMW, and other autos here, fix it right the first time, and prevent problems from happening in the […]

By | March 13th, 2015|Case Studies|Comments Off on BMW Engine – When Good Oil Pans, Go Bad – Oil Leaks

Drive Oil Level Data Drive Oil Level Data

I title this when “Good Oil Pans Go Bad” to illustrate a point, 99% of the time, the engine oil pan does nothing but hold your engine’s oil, but when the gasket between the engine block and pan fails, it’s a bad thing.

What
Aside from the engine oil leak making a mess in your garage or parking space, and possible engine damage from low oil level, that oil has a nasty habit of finding it’s way to your engine’s catalytic convertor. Oil on a very hot […]
