Hello! A window losing operation can be the result of a failed window regulator and motor assembly. Have a mechanic inspect for electrical faults (https://www.yourmechanic.com/services/electric-problems-inspection) concerning the window first.

Check clutch pedal assembly bracket for breakage or mis-position. It's also possible that the pressure plate is to blame. However, before diagnosing that you do have to confirm the hydraulics work. Even though the master and slave are "new", these...

Hello! The easiest way to locate a coolant leak is to have the cooling system pressure tested, which can be performed when the engine is cold. The most likely failed component would be the coolant pump. It's usually good practice...

It is very likely than an ignition coil could be the cause of this issue although it would most likely set a check engine light if this was the case. I would recommend turning your key to the on position...

Hello. I strongly suggest checking the starter, alternator and even the new battery to make sure that they are all in working order. Testing those three will give you a better perception of why it's not starting. If you need...

The BMW manufacturer considers 1 quart per 750 miles for normal engines and up to 2.5 quarts on motor sport engines. Under heavy loads the engine will use more oil. This is what BMW says is normal. You should not...

There are three components most common to be the source of your failure, according to other owners: the radiator, water pump or the coolant recovery bottle. I recommend having a mechanic, such as one from YourMechanic, inspect your entire cooling...

P1318 relates to spark plug voltage detection. This function might be integrated into the DME on a BMW. If not, there will be a module (VDM) and the code will typically refer to an open or shorted wiring harness. Diagnostic...

Hi Pam. Thanks for contacting us tonight. In most cases when a car overheats, it causes steam to escape and can cause damage to sensors and other electrical components. This is likely why you're having difficulty starting the vehicle, turning...

Hi Deshawnda. Thanks for contacting us today. Although some "mechanics" recommend using a liquid head gasket sealer, the truth is that 80% of the time - it doesn't completely do the job - or it causes additional problems. These sealers...

If the clutch pedal goes down without engaging the clutch. The fluid level needs to be checked in the clutch reservoir. If the level is good then there is a bad seal on either the master or slave cylinder. If...

Hello. It sounds like you have either a major computer failure or a failed instrument cluster. I would recommend enlisting the assistance of a qualified professional who has the necessary tools to test your instrument cluster for proper function based...

Hello. I'm sure this is been done but ensure that the clutch release bearing and a whole clutch kit was installed when you replaced the clutch. A complete couch job consists of a pressure plate, a flywheel, a clutch disc...

This is a very broad question with little information to go on. The most common causes of overheating are low coolant or the engine cooling fan clutch since your car has a mechanical fan. More information would be required to...

If your car keeps cutting off, then this may or may not be related to the fuel line. If you suspect it is indeed related to a fuel line, then that means that fuel is probably leaking, and the vehicle...

Your brake pedal may not be returning all the way. Because the switch is activated by the motion of the pedal, if the pedal does not swing back all the way to it's stop, it may not turn off the...

Hi there. To be honest, when the alternator tests as good and the battery terminals are good, this issue is typically very difficult to diagnose. In most cases however, this is either an electrical relay fault to the charging system...

The coil melting is the first issue to address. A possible cause of that is the 12 volt primary side supply wire to that coil is shorted to ground due to a pinched wire or other wiring fault. You can...

Hi Dan. Thanks for the question today. In regards to geometry, handling and "whether it's fine", a dust cap should not have that great of an impact. I'm curious as to why the mechanic did this - as to me,...
