Bmw Owners Clubs In Sri Lanka ?

[VVTi]

is he capable enough to work on the car himself if i were take the Z to him?

oh & how "drear" is "dear" ?? ?

He has a garage at the back machang. I saw about 5 cars being worked on. He sits in the office and the machine is inside.

For the injectors and the 12 O-rings i parted with 7K.

Bring a 6 pack and bites, and Ripper you and I can remove it all..

Hi VVTI

Thanks for sharing the details of the injector clean up and process. Appreciate it alot.

Called the Prest*** last afternoon and they apparently undertake the cleaning ultarsonically for approximately 8k. Thought of taking mine Monday morning and they said that it was a half day job. What do you think?

Honestly, I haven't got the expert in Kela to clean any injectors from all the times I have been there.

Glad that all the efforts paid off well buddy !

Thanks and Cheers

Ok, went to ASNU in Talangama today, the gentleman who owns the pleace is a veritable encyclopedia on anything Fuel Injected. (Waiting for Mr. Wije's "I know him from Donkey's years... ).

Anyway, as expected my injectors were far from perfect, fuel was just being sprayed in a very undignified manner when he hooked all 6 up to the Cleaning/testing gizmo. The machine tests the injectors for pressure leaks, pulse errors, stuck 'pintles' etc etc.

He also told me the difference of the different colored injectors. THEY ARE THE MOST CRITICAL INFO about the injector you have. Each color denotes a different voltage and pulse width it works on and any deviation from these very tight tolerances can cause irreparable damages. This basically means, stay away from guys who hangs a Injector cleaner bottle from a tree and hooks up your injectors to a AC/DC converted pulse generator. Trust me, there are quite a few out there who has done it like that and sadly, moi once got the N16 cleaned like that. God help the new owner...

Anyway, so after the testing, which included the spray patterns while idling, 1000, 2500, and 5000 rpm he dunked them in a cleaning solution within a Ultrasonic generator and let it do its thing for 20 minutes. After 20 minutes, took them out, dried with compressed air, put 12 new O rings, packed them nicely in a sealed polythene bag, smiled and gave me the bill...

Came home, put it all back, cleaned the throttle body and MAF sensor since I was on a roll and just fired her up and took her for a test drive.

Fired on the second attempt, struggled a bit and settled down.

A test drive around a bit hard on the Campus/Royal road to the annoying look of the traffic cops and other home bound commuters, and I am now a very happy man.

She feels smoother and the pick up and response is better than it was yesterday.

Thank you MadMMX for the heads up!

ASNU is the place to go for your injector cleaning... he is a bit dear, but its worth it.

[Rukster]

Machang, just look up on the Pelican Articles on your specific engine and how to remove. That's how I did it. I was under the impression you are regular customer of the Kelaniya Specialist. I am sure he will be able to pull them off for you.

Will have a look buddy. Thanks !

yeah...but i doubt a six pack would do though...last time we went way over that

7 long necks if i'm not wrong

yep...

Basically bring all the beer you can carry.... We might need it all.

[MadMMX]

Hmm

If you post your engine model or the first 7 digits of your engine no (eg - KJ88664) can pull the TIS procedure (which is pictorial) and post it ?? Really not a difficult job ?

hi guys

I'm in the process of acquiring a 2002 525i (E39) with 90,000 miles on the clock. It's been looked after first by agents, now at Kelaniya. Cleaning the injectors sounds like a good thing to do, but not being mechanically minded I cant pull them out. Would Pres**** be worth it? Doubt they will only charge 8k, as it usually costs 5k before they've touched the car :-)

Its actually no issue to pull them off... and its a misconception that the agents charge like that.. probably a rumor spread by certain people to pull in more business...

[NahoY]

thanx....

Ive found that if I dont use 95 octane the engine runs quite rough .. is this normal?

[MadMMX]

Actually totally agree with this comment. You may be surprised. When I first started going to Pre***ge many years ago I was also very apprehensive. However I did find that the labour charges were not what I thought them out to be (in a good way) However the labour on some jobs is pretty high (eg - to replace the gearbox shift oil seal on my E46 the oil seal itself from uk cost 2 pounds but the labour was 24k - the reason for this being that you needed to remove the complete exhaust and the propeller shaft..etc to get at it) so for this type of job its always prudent to request a quote from them before hand.

However I was actually sent their by our Kelaniya friend when I retrofitted my OBC (on board trip computer) stalk as it needed programming - he told me that he would have to charge 12k to program it as his DIS had been bought in partnership and every time he used it to program he needed to pay his partner X amount of money. But he suggested I go to the agent and they did it for 2k !! I was actually pretty surprised at the time. I do find that for stuff like servicing and all its worth taking it there and you also get the benefit of the records being kept at the agent. Of course this was before I managed to hook up my own DIS at home and now can program all the hidden options without any worry of cost

Probably worth asking them how much it would cost - but then again I'm not sure they would like you taking the injectors away and getting them cleaned and bringing them back for them to fit. They have their own method of cleaning which I believe involves just soaking the injectors in fluid or something - but no ultrasonic cleaning.

Cheers,

[MadMMX]

Shouldn't be the case as the engines are all certified to run on anything over 87 octane. You only loose some pickup. Best to check the records and see when the last time stuff like the fuel filter / air filter / plugs ..etc were changed. The fuel filter does get clogged over time and when they clean it out you get some nasty black colour goop coming out of it. Our petrol does tend to clog it and its fairly pricey - about 15-18k but its worth changing it once in 2 years.

Of course always better to run 95 as you get better pickup and gas mileage

Madmmx, did u have a facelift 3 series by any chance with the common rail engine? if so have you got any experience on the infamous swirl flaps in the intake manifold?

HI rangerover

My diesel was a pre facelift and I moved to a petrol facelift 318i. However I have taken the manifold off my current car to replace the pcv and its not really a very difficult proposition. The removal procedure is detailed with pictures in the TIS DVD. Have heard of the swirl flap issue extensively and friends in the UK definitely get their facelift 320d's de-flapped For peace of mind without a doubt I would remove them as some of the stories I've read are terrible. In fact it seems that BMW themselves have modified the newer swirlflaps to all plastic ones as of 2006 or something. Actually the manifold removal doesn't require very extensive mechanical skills. (I certainly don't claim to be an expert ) just a bit of dutch courage when pulling parts out and a good memory as to where the screws and nuts you pulled out came from.

Give me the first 7 digits of your engine no - (like KJ88664) and I should be able to pull out the manifold removal procedure from the TIS and post it here. Alternatively you can give this to your usual garage mechanic - sit with the chap and watch like a hawk and get him to do this. Removal on the BM's is strangely more simpler than most jap cars that I've touched - also possibly due to the good documentation available for them.

Cheers,

After running for a few days with the newly cleaned injectors, I highly recommend it done on any EFI car!

In addition to the extra smoothness, the pulling power has vastly improved and though I hate to mention this, I have used only 2/3rd of the fuel I would normally use by this time.

Now I am convinced the -In-Tank remedies are a short term solution to a long term problem.

[Sifaan]

Has anyone heard of a system where the additive is poured into the intake (rather than the tank)?

the way I understood it being described, pretty much the engine runs on the additive for about 30 mins.

Advantage is that it's supposed to do a thorough clean up of the injector, but disadvantage is that it ruins the spark plugs and they have to be replaced.

btw this was described from an agent workshop, not a maka bas

Hi NahoY

I just did the injector cleanup and the car just flies ! They really decent than I thought and the service was good. It actually costed ~9k.

Its worth it !

3M injector cleaners work like that...you hook up the can to your intake and the motor runs off the can!

Wurth has a spray that you can spray into the throttle body via the air inlet...

what you add into the fuel is a "fuel system cleaner" where it's supposed to clean out the gunk and other forms of deposits throughout the entire system

dunno if it works or not but i've been using the wurth fuel system cleaner about 3 times an year

[harshansenadhir]

This is a killer for a cat IMHO. It emits lots of carbon particles and excessive amount of chemicals in one go. This amount can be equivalent to the emission gases goes through the cat in few years or so. One time blow up of excessive carbon particles would result in block the cat and reducing the effective reacting area of the cat. Further, it'll put all dirt/build up on injector lines inside to the combustion chamber at once, don't know the impact what it might cause.

And is it normal to bugger up the sparks?

Thanks for the clarification... because of the earlier comment on "in tank" solutions I thought injector cleanup was also done through a fuel additive.

when you say you use the cleaner 3x/year - what's that in terms of km?

But this is the only alternative other than removing the injectors and cleaning?

How do 3M/Wurth recommend dealing with the cat? can it be removed/bypassed temporarily?

i've never used the 3M can solution.

Only wurth fuel system cleaner which has become kinda of a habit now and no...i've not seen any bad things happening to sparks!

and IMHO...the best way to clean the injectors is via direct intervention as VVTI has explained!

you leave no doubts that way provided you get in done from a reputed place

and no idea about the mileage mate! thrice a year or so i just buy the damn thing and use it. mind you i do the manual injector/tbody cleaning also...but that's done once a year or so

In-tank solutions will not result a sudden emit of carbon particles unlike when the engine is running on the cleaner. Have you seen how smokey is the exhaust when running from a cleaner? it removes certain amount of carbon deposits inside the chamber and on the valves as well. These particles will healthy for the honey comb of the cat.

[Sifaan]

well, how many km have you run in the past year? My running is quite low so I can't imagine doing a clean up 3 times a year
