Yes, agree.

Recently my mechanic met a BMW owner which i believe might be scam by some workshop.
Some owners are phobia about oil leak or any warning symbols coming out from the meter and did not have basic knowledge about cars. With this weakness some workshop took the opportunity and scam the owner by saying the need to do major overhauling or expensive repairs which actually just did few gasket or oil ring change...

Nothing against owners who want to drive BMW for the brand or luxury, but I highly recommend a Lexus or something else that's reliable if they aren't an enthusiast, or at least aren't willing to put in the research to know what are the causes of issues, etc and just let a workshop take care of all the maintenance. But of course, it's not their fault as the workshops aren't even suppose to be scamming people in the first place.

This is a sad truth as a lot of workshop mentality is that people which can drive BMW, Merc (Even Lexus) must be rich people and willing to pay more.. I think if you really do research or survay, 10 workshop 9 of them for sure will say charge the BMW, Merc owner higher for similar job.. laugh.gif

Agree with you on BMW or other high rm cars.
However, I believe quite the same thing happens to entry level cars with owners being advised on (major) overhauls for minor leaks here and there.
Can't blame general population for 'lack' of basic knowledge on car maintenance but it's good be humble to ask and seek advice from reputable fora and knowledgeable friends, if any.
Mechanics are a source too, but with vested interests in particular the SC's.

A basic warning issue pop out from idrive or dashboard indicate that error not necessary is that particular error, better get a OBD port scanner to check which area is in fault. Might be battery

Scammers will be scammers and those without knowledge will continue to fall for it regardless of the car they drive. Even a Axia owner can be scammed. But the probability might be higher with BMW/Merc owners as a sizeable majority are just into them for the brand alone...

For modern car, it makes little difference for most traditional 3rd party mechanic if it is Japanese or not. What they usually do are oil change and replace battery, alternator, suspension arms, brake pads, shock absorbers etc something mechanical externally.

20 years old engine they still can fix. The one near my place once got a Camry Hybrid with check engine light but still able to drive, he basically looked at engine bay, then closed the hood and told the guy to go back to Toyota. They can't even read a full English sentence, don't expect them to deal with computers.

One famous example is engine oil sip usually caused by PCV valve clogged, because engine unable to equalize air pressure inside the block to atmospheric pressure. BMW and most continentals adopted direct injection and turbo for many years + Malaysian basically can not walk and do a lot of short distance drive, that contributed to the problem. Otherwise the PCV would last 80,000km+. So knowing the principle, 90% of the case only need to change PCV. The old mechanic either think it is BMW design problem, or simply change engine gasket. There goes the urban myth BMW always leak oil. With the Japanese adopting more modern tech, the old dogs going to see more stuffs they don't understand. "Got sound change the part" approach no longer works

For the 3rd party modern specialized shops that have real knowledge and up to date with technology, usually famous within the region. They knows how to deal with modern cars, have reputation to keep and don't simply scam people.

Ah yes, another common statement I've seen is "driving short distances often is not good for ur BMW". May I know more specifically how short-distance driving contributes to the PCV issue?

So during this lockdown period daily drive go tapau food a few kilometres away is a no-no for the engine?

Actually not limited to BMW, but any cars. Just direct injection + turbo the effect is more prominent.

This goes back to the purpose of PCV (Positive Crankcase Ventilation). Here's some history and development over time.

- the pressure of crankcase where the engine oil at is not static
- piston movement cause fast pressure change, and blow-by are adding more air to the crankcase
- The earlier engines have no ventilation and no gasket, oil leak is normal. Then gaskets were added but doesn't fix the problem. Because the pressure is pushing the oil through any gaps possible.
- The people started to make small hole at the top of the engine to release the pressure, but this is still not PCV
- This release the pressure, but the blow-by, the unburned, burned carbon etc are still containment the engine oil
- Here's the next design, connect bring a simple rubber pipe from the vent to the bottom of the car. Then open another hole to vent in fresh air, known as breather valve
- This fast moving car create low pressure (relative to the crankcase) at the bottom of the car, thus suck the air out naturally through the rubber pipe. Fresh air goes into crankcase via breather
- This is first iteration of PCV and Breather
- But the dirty air is now vented to atmosphere, the government started to mandate rules to ban this cheap but polluting solution. California is the first in the world.
- The new solution is to vent the PCV out air back into engine intake. Thus recycle the dirty air into engine to burn off. This also have other benefit of lower the combustion temperature and reduce other form of emissions.
- For NA engine intake manifold is always negative pressure, we have vacuum from the intake manifold to pull air from PCV.
- For Turbo or Supercharger, PCV need one way valve. On idle and cruising, the intake manifold is negative pressure and pull air from PCV like NA. When on boost, PCV will close.
- So now, remember the air from PCV is dirty. For port injection, the gasoline will clean the intake valve.
- For direct injection, the dirty air will contaminate the intake system, thus the famous carbon build up issue.
- Now for more expensive cars including BMW have oil air separator built into the PCV system.
- Consider this as the OEM oil catch can, with minor different is the oil is sent back to engine. Owner no need to clean the catch can.
- Japanese and Korean (not sure about the Genesis which basically designed by German engineers) usually do not have the oil air separator.
- The common of both solutions are carbon deposit will still increase over time. It is either you want to clot the PCV first or clot the valve first. Worse enough both still get clotted.

With the background, you can see yourself how short drive affect the system. The engine have less time to warm up, some case never really warm up. Short tapau most likely driving at low rpm and low load, the airflow is slow. The fresh air circulation of PCV circulation also slow, and high frequency for dirty dead air as soon as engine off (short trip = start/stop more often per same mileage). Don't worry too much as things are much better today with advance ECU to manage the timing + better engine oil the problem is less severe. One should not worry until at least 80,000KM - 100,000KM, which the remedy is known. Check the intake valves and PCV, clean/replace as needed. One should only do this 1 time for entire car ownership, maybe 2 if drive 20 years. Unless the owner drive <1KM multiple times, daily. That's an extreme case.

Thanks a lot for the very detailed explanation!!

With this information in hand, would I be able to offset daily short trips in the mornings to the workplace with a longer drive (say around 10km) during lunchtime to avoid this problem?

Your longer drive is driven in what condition? If highway with higher speed is ok, but if the 10km also is stop start or slow traffic jam situation which is like driving in city or small town area actually is also LPPL..

That's true, a lot of idling and stop and go it not good as well.

If you don't need to do the 10km, no need to purposely drive it, that is counter productive.

If you need to do that 10km by all means, like I said now with better engine oil and advance control, it is much better than the past. Normally 80,000KM+, if you in the worst use case let's say half at 40,000KM+, go for 4S or reputable 3rd party, they know what to do. It is not an expensive fix. Further more you stay close to your work like you mentions, how long do you think you need to drive 40,000KM?

Use good engine oil, and change per manufacturer recommendation.

buy 330e, give u 40-50km electric, engine wont run. kakakaka. no need warm up car also cause electric.

my workplace is 15km from my house, so only weekend go buy sayur or lepak will consume petrol. my last refuel was 2 months ago RM50.

Electric bill charge everyday around RM150 extra.

150 electric bill per month is not cheap, converting to petrol cost means it is more expensive to run, not to mention maintenance for battery, inverter, charger, motor etc.

No wonder 330e second price suffers so much.

After buying phev, there are a lot of people asking if the auto start stop when car is idle can be switched off. There is no button for this though some work around is available

No wonder there were no stock allocations in May and June.
This cockpit is a massive upgrade.

In any case, I think this will probably eat into the 330i sales. For the average user who doesn't want the extra power and wants a more comfortable suspension, the 320i was the obvious choice. The deal breaker would probably have been the cockpit and 8 inch infotainment, along with the speakers. But now even the cockpit and infotainment has been upgraded. Just upgrade with aftermarket speakers and you've got the ideal car.

Of course there'll still be those who value the extra power from the 330i. And the M Sport steering and fittings.

And of course ... I could be wrong about all of this.

Also the bumper….got a quote outside and to convert to M sport will RM4200

Other thing is the reflective dashboard. Maybe some outside wrapping can help
