Good day sir
Nissan Qashqai
201Automatic.

Difficult to drive in the morning after starting car. If I try, car becomes slow and I hear like a wheezing noise ..like a rotor or fan belt noise struggling to roll.

But if I start the car and leave the engine rubbing for around 20 minutes, the car will move smoothly. Drives very well after it has warmed up.

Sometimes but not always, while driving, there's a slight delay during gear change.

Give thanks for your time.

I think someone reported a similar issue recently but I lost the topic.

Good day engineers in the house. I drive a 2005 Toyota camry. I've had no issues until my ABS module went bad and the "brake master" said i could bypass and it will still work fine. Since I've done this bypass, my brakes doesn't feel and work the same. Sometimes I feel like it wants to fail cos it get to soft and it scares me. This morning I noticed that when I step on my brakes, the car is reluctant to stop. Can someone recommend a very professional brake specialist for me in Lagos? I stay at Ikorodu and work in Ikeja. Please I need help.

RyanAutomotive:
Good day sir.

Vehicle: Toyota Camry 2005
Concern: ABS module bypassed, brake pedal feels soft, braking performance has reduced, and vehicle sometimes feels reluctant to stop.

First of all, I would advise that this issue should be treated as a safety-critical concern, not just a comfort issue.

Let’s address this properly before the vehicle is driven extensively.

* Important Observation

You mentioned that:

• The vehicle had no brake issues previously.
• The ABS module developed a fault.
• The ABS system was bypassed.
• Since the bypass, the brake feel has changed.
• The pedal sometimes becomes soft.
• The vehicle occasionally feels reluctant to stop.

The timing here is very important.

Since the symptoms started after the ABS bypass, the first area of focus should be the brake hydraulic system and the bypass procedure itself.


* What the ABS Module Actually Does

Many people believe the ABS module only works during emergency braking.

That is not entirely correct.

On your Camry, the ABS hydraulic unit is integrated into the brake system and plays a role in managing brake pressure.

When an ABS unit is bypassed incorrectly, it can create:

• Abnormal brake pedal feel
• Soft pedal conditions
• Air trapped in the system
• Improper hydraulic pressure distribution
• Reduced braking efficiency

This is why a vehicle may still stop, but not stop the way Toyota designed it to.


* The Soft Brake Pedal Is a Red Flag

A soft brake pedal should never be ignored.

Possible causes include:

• Air trapped in the brake lines
• Improper ABS bypass procedure
• Internal master cylinder leakage
• Brake fluid contamination
• External brake fluid leakage
• Fault within the modified hydraulic circuit

The fact that you sometimes feel the brakes may fail is not something to gamble with.


* What Should Be Checked Now

Before replacing parts randomly:

1, Perform a complete brake system inspection.

Check:

• Brake fluid condition
• Brake fluid level
• Brake line integrity
• Caliper operation
• Brake hose condition


2, Inspect the ABS bypass work.

Confirm:

• How the bypass was performed
• Whether hydraulic routing was modified
• Whether proper bleeding was carried out


3, Check the brake master cylinder.

A weak master cylinder can create:

• Soft pedal
• Inconsistent braking
• Pedal sinking under pressure


4, Perform a computerized diagnostic scan.

Even though the ABS module was bypassed, a professional scan can reveal:

• Stored brake system faults
• Wheel speed sensor issues
• Communication faults
• Other related brake system abnormalities


* Do NOT Do This

• Do NOT continue high-speed driving until the braking system is verified.
• Do NOT assume “it is normal after bypass.”
• Do NOT rely solely on pedal feel.
• Do NOT keep driving if the braking performance continues to deteriorate.

Brakes are one of the few systems where guessing can become extremely expensive and dangerous.


* Professional Insight

From your description, I am less concerned about the original ABS fault and more concerned about what happened after the bypass.

A properly functioning brake system should inspire confidence.

The moment a driver begins to fear whether the vehicle will stop, the system requires immediate professional attention.

The soft pedal and reluctance to stop suggest that either:

• The hydraulic system is not operating correctly,

or

• Another underlying brake fault was overlooked during the ABS bypass process.


* Ryan Automotive Limited Recommendation

The next step is not another bypass or another “brake adjustment.”

The next step is a structured brake system diagnosis involving:

• Professional computerized scanning
• Complete hydraulic system inspection
• ABS system evaluation
• Master cylinder testing
• Brake pressure verification
• Road-test validation

At Ryan Automotive Limited, brake-related complaints are treated as safety-priority cases because your ability to stop is more important than your ability to move.

Since you are based in Ikorodu and work around Ikeja, you can schedule an inspection with us in Lagos.

We attend to vehicles from different parts of Lagos and beyond, and we would be glad to carry out a proper assessment of the braking system to determine whether the issue lies with the ABS bypass, master cylinder, hydraulic circuit, or another component before any money is spent on unnecessary repairs.

Please who can help inspect a car in Abuja


I need an honest inspection

Abbeyismo:
It not good to buy pass tho
But sometimes if the by pass is done properly it works, you might be having issues with ur break master or break savo and not even the abs. Because sometimes if they bypass it properly it will work.
You can reach out to me my workshop is around Abule egba.

Sannideen:
Thank you sir, help me drop your number.

Good morning house. My 2008 c300 is moving only on gear one. I’ve changed oil and filter. Scan detected valves and it was changed but it still moving only on gear 1. Any hear experts here?

Dabadwela:
Seun please ban dis man.

Why post a whole Chatgpt script all the time and expect people to read all this. You call yourself a professional technician and you dey use AI dey spam everywhere. So what's the difference between you and me wey get access to the same AI?

RyanAutomotive:
Good evening sir.

Vehicle: Honda Civic 2009
Concern: Engine shuts off when coming to a stop after driving for a long distance.

Let’s address this properly before replacing parts unnecessarily.


* Understanding the Symptom

From your description:

• The vehicle drives normally for an extended period.
• The problem occurs after a long drive.
• The engine shuts off when you come to a stop.
• You did not mention any warning lights or fault codes.

This is an important clue because the issue appears to be temperature-related or operating-condition related, rather than a complete no-start problem.


* Important Information Missing

Before a precise diagnosis can be made, it would be helpful to know:

• Is the Check Engine Light on?
• Does the engine restart immediately after stalling?
• Does it crank normally after it goes off?
• Is the A/C usually on when this happens?
• Have you scanned the vehicle for fault codes?

These details can significantly narrow down the diagnosis.


* Possible Causes

Several systems can cause a Honda Civic to stall when coming to a stop after driving.

1, Dirty or Malfunctioning Throttle Body

When you release the accelerator and come to a stop, the throttle body must control airflow to maintain idle speed.

If the throttle body is dirty or not properly calibrated:

• RPM may drop too low
• Engine may stumble
• Vehicle may stall at junctions or traffic lights


2, Faulty Idle Control Strategy / Idle Relearn Issue

On some Honda vehicles:

• Battery disconnection
• Throttle cleaning
• Electrical repairs

can affect idle learning.

The result may be:

• Unstable idle
• Stalling when stopping
• RPM fluctuations


3, Weak Fuel Delivery When Hot

Some fuel pumps work properly when cold but begin to fail once they heat up.

Symptoms include:

• Normal driving initially
• Stalling after extended driving
• Difficult restart when hot


4, Faulty Crankshaft or Camshaft Position Sensor

These sensors can become unreliable when engine temperature rises.

When this happens:

• Engine may suddenly shut off
• Vehicle may restart after cooling down
• Fault codes may or may not be stored


5, Vacuum Leak or Air Intake Issue

Unmetered air entering the engine can cause:

• Poor idle control
• Stalling at stops
• Inconsistent engine performance


* What Should Be Checked Now

1, Perform a professional computerized diagnostic scan.

2, Check for pending fault codes, not just current codes.

3, Monitor live data including:

• Engine RPM
• Throttle position
• Fuel trims
• Coolant temperature
• Fuel system operation

4, Inspect and test the throttle body.

5, Verify fuel pressure under operating temperature.

6, Evaluate crankshaft and camshaft sensor performance.


* Do NOT Do This

• Do NOT replace the fuel pump based on assumptions.
• Do NOT replace sensors blindly.
• Do NOT continue driving for long periods if the stalling becomes frequent.
• Do NOT rely solely on mechanics guessing from symptoms.

Proper diagnosis is always cheaper than replacing multiple parts unnecessarily.


* Professional Insight

The fact that the vehicle only stalls after a long drive suggests that heat and operating temperature are playing a role in the fault.

In our experience, common causes on the 2006–2011 Honda Civic platform include:

• Throttle body issues
• Idle relearn problems
• Fuel delivery problems
• Crankshaft position sensor faults

However, the exact cause can only be confirmed through live-data diagnostics and proper testing.


* Ryan Automotive Limited Recommendation

The next step is a structured engine performance diagnosis, including:

• Professional computerized scanning
• Live data analysis
• Throttle body evaluation
• Fuel system testing
• Sensor performance verification

At Ryan Automotive Limited, we diagnose the root cause before recommending any parts replacement, helping clients avoid unnecessary expenses and repeated repairs.

If you’re within Lagos or can bring the vehicle down, Ryan Automotive Limited can carry out a comprehensive diagnostic assessment to determine exactly why the engine stalls after extended driving.

Even if you’re coming from outside Lagos, we attend to vehicles from different locations and would be glad to assist.
