Hey guys, i was driving my holden cruze diesel 2010 just about 15 mins ago. its 32 degrees out there and all of a sudden there was this loud bang from somewhere in left hand side. But yer after that the exhaust sound was loud and the engine power reduced. im not sure what went wrong there but yer after a while, i got this yellow vehicle inside there was that allen tool i think. and gave me code 84.

My question is what might have gone wrong there? rear exhaust sounded the same, engine sound is perfectly fine. the noise is coming underneath somewhere. Can this be the exhaust came out from the engine or something? i dont wanna go to holden koz they will definitely overcharge me. I can tell with experience.

One thing i definitely learnt, I will never buy a holden again. im normally a bmw type guy. never had anything like that in any of my bmws before. Help will be much appreciated

84 is a generic "Engine Power is Reduced". Get your car to a mechanic who knows diesels and have them look under your car. You blew something out.

BUSHINGS:uhh:

Hey eddy how would the Bushings cause a reduced power by the ECM ?

A backfire in the intake through the exhaust Manifold would cause a CEL and result in a Reduced power scenario .

This 1 is for the Diesel guys !

dad's mechanic is saying that there is a high chance that the exhaust is loose from the engine end. the engine lost power koz there is not enough compression for the turbo to push the engine. he is only assuming, he will jack it up tomorrow and see whats going on.

now guys another question. is it possible that the turbo is too weak or too powerful for this engine? im a smooth driver, so this is the first time a car has issue while im driving. we never played around with the turbo too much as me and dad is obssessed about cars. now this is new so yer we take very good care of it

Have you been servicing the car regularly?

And been having it done by someone who has fronted up the Oxford Scholars to get the information from Holden that is needed to be able to service the diesel properly? They aren't the same as the old diesels that most macs are used to working on, there are quite a few subtle surprises.

If you are in Melbourne I can recommend a couple of dealerships that aren't too bad, there are a couple of other Aussies around that could point you at decent places in Sydney, FNQ ,and Perth.

And don't bother complaining about Holden- they are pulling out of manufacturing in Oz, once they and Ford and Toyota are gone, your BMW's will be costing a metric ****ton more.

As will the bog standard Hyundais and Kias and so on.

Been years since I have worked on diesels in farm tractors and semi's, all mechanical pumps back then 1,500 psi. Today, electronic control, firmware in flashram, piezoelectric electronically controlled injectors. Just saying, a bit more complicated.

Would be nice to have free access to firmware, can, if you want to layout a huge fortune, but not right in my opinion. With any computer problem, address software issues first to learn if you have a hardware problem. No longer a vehicle anymore, but a computer.

So forced to get into bed with your dealer, wouldn't be bad if she was a good looking gal, but not with that hairy guy, no way. EPA in the USA insist this must be done by a skilled dealer, guy I met don't even know how to switch a computer on let alone use it, and charge 90 bucks an hour trying to find the correct software. But the EPA should only be concerned with emission, and what in the hail does this have to do with the BCM and the radio? Can't even get access to this firmware, we are sure getting screwed, and screwed blue, why are we being quiet on this issue, we are the idiots for putting up with it.

One solution is to leave the darn things in the showroom where they were designed originally for.

Semi's and farm tractors have one extremely huge advantage over our consumer crap, the exhaust systems go straight up into the air and rarely if ever go bad. On our consumer junk we buy, put all this super way overpriced crap under the vehicle where its exposed to all kinds of road salt and debris.

You begin to realize this if you know how to think. Thinking is not good for us, just accept it the way it is and pay through the nose.

Ha, cops say nothing about loud diesel powered trucks or locomotives, super loud, jet planes, emergency vehicles with sirens, or even motorcycles with straight pipes. But if driving a consumer type vehicle with a tiny hole in your muffler, will stop you.

oh yer just got back from the mechanic, hahaha what a funny and wierd guy, he was saying "your turbo needs replacing as it wouldnt send any pressure to the engine. as i am very fussy about my cars i always stand by the mechanic and see what he is doing koz i dont trust em. yer i had a look after he said all that and i started the car, engine sounds good as new and push the gas and heard the turbo whistling with no issues. i called my friend and told him about everything that guy said and he laughed at me. he asked me to check the turbo intake, when i checked Bam! problem found. turbo intake pipe popped off. and i called the mechanic from his "office" and pointed the problem. hahahahah bloke turned tomato red!

anyways i asked him to pop it in with a new seal (with the screw) and went for a test drive, WOW car's performance is so much better than it was before. paid him his $45 labour and got outta of there and thinking to myself WOW you are really a professional mechanic that cant even spot a simple problem.
