Reviving the BMW 5GT: A Mechanic's Journey

Among BMW vehicles,

the family car daily car has received a lot of love

The Gran Turismo (commonly known as GT)

was popular from 2010 to 2017

and sold well

Even though it has been discontinued, it’s still active?! Haha

Today’s star is

the BMW 5GT (F07).

The conditions for maintenance are the worst.

The vehicle is old with high mileage, and

the owner claims it has only been serviced at the service center..

The manual states that detailed maintenance cannot be performed

and a lot of money has been spent on it. ;;

Did the owner feel that way too?

While searching for a specialized BMW import car shop,

they came to our store

After the consultation, we decided to first address the lower rattling sounds

and resolve the coolant issue.

The BMW 5GT maintenance involves major repairs!

The lower rattling sounds and squeaks!

Lower arm tension strut stabilizer link

The coolant leak issue

The reservoir tank (auxiliary tank)

Additionally, the oil pressure sensor

This post includes a lot of photos and text due to the length of the work log.

Near Hwaseong Dongtan Osan Suwon

A great place for BMW maintenance!

NAVER & KAKAO "Geoka"

First, we address the lower rattling sounds.

When going over bumps, manholes, or uneven surfaces,

you hear rattling and squeaking sounds.

Let’s resolve this first.

The vehicle is old with high mileage, right?!

Upon inspection, most of the suspension parts

have reached the end of their lifespan.

However, it’s not easy to visually check for a blown shock absorber

The stabilizer bushings are only available as original assemblies, which are expensive.

The rear part generally does not produce noise

Considering all of this!

Let’s start by replacing the front lower components

lower arm tension strut (tension arm, control arm)

and the stabilizer link.

What products are we using?! Lemforder

We use this brand the most as it is known for its OEM production quality~

The defect rate is lower than that of genuine parts, so we prefer it..

However, a major downside is that among aftermarket OEM products,

the price is the highest. Haha;;

The car owners might think.. since the used car price is low,

the repair costs are too high compared to the car value.

However, we have experience in this matter and

In the long run, we believe that it’s better to invest properly once rather than half-heartedly and not see the benefits for long.
Let’s do it right the first time!

Especially for these older BMW models,

The quality of Lemforder products is significantly better than that of recently released vehicles

Most of the manufacturing takes place in Europe, particularly Germany.

There’s no reason not to use it.

If you’ve made up your mind.. we’ll make sure to handle everything from the product to the work process, so just trust us and come in!

Let’s get started with removing the parts.

The tension strut, which had the most problems..

We’ll take a quick video to show how easily the bushing moves with no resistance.;

Finally, it separates like this! Haha

Applying force with my hand breaks it easily. Haha

This was a close call.

While maintaining the BMW 5GT,

I took a photo of the 5GT next to it.;

While maintaining, I checked for any unexpected variables.

I checked the rear suspension bushings and ball joints.

The rear air springs are also prone to failure.

Let’s check them too!

While maintaining the lower parts, we encounter various unexpected issues, so we must keep checking.

Even if additional costs or repairs arise,
if we’re going to do it, let’s do it all at once..
If we complete everything and there’s a problem?!
It becomes a waste of both money and time..

We’ll replace the stabilizer link and

We’ll assemble the lower components while marking them.

For older models, even if we follow the manual to tighten bolts and nuts,

They sometimes come loose later on.

So, to ensure everything is secure, we prefer to mark them.

We’ll tighten the bolts and nuts carefully, as there are many things to pay attention to.

This is the stabilizer bushing, but

This part does not come separately.

Although there are cheap Chinese versions available,

Since it must be attached directly to the stabilizer,

It’s meaningless.. you must use the genuine part, which is expensive.

The price is roughly in the upper 400,000 KRW range (around 300 USD).

It’s not worth it to use cheap parts for maintenance.

So, we’ll check for any noise issues before ordering parts.
We’re currently performing the repairs~
Although I didn't mention in the title, there’s an oil pressure sensor located near the oil filter housing.
After checking, we found issues with the part and oil entering the connector.
The price for this is quite high.
The coolant issue is mainly caused by the reservoir tank, which has been leaking for a long time.

Additionally, the coolant cap (a common issue with BMWs) must be replaced!

We’ll replace everything!
The parts will be genuine.

If you don’t use genuine parts, the sensor that checks the coolant level tends to fail frequently, making it impossible to turn off the warning light.;

The coolant tank has been leaking for a long time, and it seems the repairs were delayed for too long. Haha;;

We’ll take before and after photos to clearly show the changes.

Before releasing the vehicle, we’ll conduct a test drive.

Since it’s a customer’s vehicle, we’ll be cautious and not go too far.
We’ll stick to our own route!

The BMW 5GT maintenance was quite a significant task.

Fortunately, the results turned out great.

The owner came in for a test drive.. OK
They texted after getting home, saying they were very pleased.
This is the best outcome!~

We also feel satisfied and rewarded for our hard work.

The owner spent money, but they feel good about it. Haha

Thank you.
