Hello All,

I need help,

After DFP warning for few days (used to clear it with going to the high way, but didn't have time to do it this time), now the car is showing error code 84 with engine alarm light on and P246C fault code when I check with torque.
I have to say that the car is working fine, no problem at all, only the alarms!

I have tried so far every thing I have found on the internet but nothing works!!
1- going on the high way for 30 mins running on the 4th and rpm above 2000.
2- cleared the fault code with the OBD tool, the code disappear for 2 secs and the DFP alarm comes back and then after 2 secs the DFP disappear and the code 84 and the engine alarm is back!!
3- I removed the negative battery terminal for 10 hours !
4- disconnected all the Fuses for 30 mins

Nothing work !!! and I still have the same problem !!!
Chevrolet is not any more existing in France and all dealers have no clue !!!

Any idea ?

Hi Aladdin, welcome to forum. When you say you've searched the net - did you search this forum?There are numerous posts on code 84 plus associated DPF issues so if you use the forum search tab and type in 'code 84' and 'DPF' you will find lots of suggestions.
Other than your post being in the Orlando section you dont tell us any more.....ie year /model / mileage etc.
I suspect that possibly what has happened is the regeneration cycles have just about been enough to keep the DPF warning light off but has gradually resulted in the DFP sensor its self becoming 'clogged up'. So even if you are cancelling the error code it comes back because the sensor maybe needs cleaning (or replacement) even if the DPF itself is reasonably clear.
The other item that can affect the air flow and thus the DPF is the EGR (exhaust gas recirculation valve/sensor). This being clogged up seems to have a 'gremlin effect' on other issues concerning the airflow combustion and exhaust.
I would look at these two possibilities first. DPF sensor & EGR.



I've just looked up code P246C which isnt on the Captiva list that I have but shows P2463 (probably same thing ie A=1, B=2, C=3) which says DPF filter soot accumulation above maximum threshold.
I would try a good dose of DPF cleaner/additive this just might do the trick before removing DFP sensor or EGR.

I've found some useful info on the DPF on the Australian GM Holden website.Some useful straight forward explanations on its operation, use and mode of function.
Link:- Scroll down list for DPF and explore other sections as you wish

You dont tell us where you are located on your personal data so I'm simply guessing you are in UK.DPF cleaner is available from virtually any motor parts or high street accessory shop. Add to fuel and drive. Simple as that. It may well be necessary to run a second dose because yours sounds to be fully choked up. Then try the EGR; then the DPF sensor. The latter two options may be dealer visit as you sound unsure mechanically (no offence intended)

Have a look at product on this link: (sorry it's a long one - not my fault as it is off the web page)

Hi Aladdinh and anyone else with same problem,

I know you tried similar process but would like to point out the situation I found myself in.

I too have had the DPF light (diesel particle filter light for anyone new to the process) come on a number of times along with cooling fan on full speed which with this model usually means its time to take it for a run.

I have the automatic gearbox version and have also read on line that for quickness while on a Motorway run (and whilst DPF light is showing) drop the car into 4th manually which in turn will cause the car to bump up the revs by a couple of thousand and therefore work the engine harder , make it hotter and in turn naturally burn the excess particles it has collected from the filter as its designed and every ones happy including the MOT emissions tester.

BUT on the last occasion I tried that I too fooled the Car into thinking that it had engine problems and PING on came ' Error code 84'..... I immediately put the car back into drive and pulled off at next junction. After stopping the car every thing seemed ok and the engine was purring , check my oil level and guessing I caused the problem by driving 4th turned around and went home by a A road.


I then read that disconnecting the battery sorts the error code 84,
So I disconnected the black battery terminal for around 40 mins before replacing it very tightly ;-) and it cleared the problem... The car actually drove better after this than before.
I needed to reset the Time and date after that and maybe a few presets / prefs the car had in its memory via the info entertainment centre. But all saved radio stations where still there.

That was around 3 weeks ago and everything has been fine since and engine is at full power and running sweetly.

SO AS LONG AS YOU THINK ITS your driving style causing it you can try the battery trick.

If error code 84 does happens to you the first I would recommend is to check you Oil levels and you your gearbox fluid levels because it could be something different.

I also used a bottle of 'Comma Diesel Magic' in a near full tank which I feel works well, cleans the system also contains Cetane which makes the car a flying machine for a while.

Another point Id like to make is please make sure you only use the correct specification Motor oil as others can produce more soot than the engine is designed for.

As for the DPF light , the filter will need to clean itself as it is designed so if you do many short trips and not many long runs in a diesel car then you could have the same problems with many makes , incidentally my brother in law who lives in London has the very same problems with his DPF on his Ford Focus.

Not sure why you needed to disconnect any fuses if you forget which way round then that will cause more problems then I have space to mention? I Wouldn't recommend playing with fuses at all apart from maybe applying a little pressure to make sure they are in position correctly.

Hope that helps someone out there.

Hi, I’m new to this so apologies if I’m repeating something I’ve missed. My Orlando LTZ vcdi is showing error code 84. Anytime the diesel filter light comes on I take it for a drive to clear it. I tried to do this today but the code 84 came up and now I can’t get it off! The car is losing power and I can’t go over 60mph. I’ve bought dpf cleaner and took it for another drive in 3rd gear but it still isn’t clearing. I’m not mechanically minded so please treat me like a moron who knows nothing - fingers crossed someone can help - thanks

Code 84 is simply a generic 'something is wrong' code across numerous GM vehicles. The vehicle usually goes into safety mode of reduced power. Unfortunately the cause can be a list as long as your arm. It is a bit like your lights going out at home. It could be the switch, the lamp, the fuse, it could be a man digging a hole in the road, local blackout etc etc. Code 84 is so vague it does not in itself say what is wrong so it is probably the most useless code there is!

You cannot assume code 84 has anything to do with DPF although your use of DPF cleaner was a good first try. It could be as simple as a dirty / blocked air filter through to a throttle problem.

The only way to make headway is to obtain a diagnostic report (using an OBD code reader capable of reading GM codes) this is best done at your GM dealer - where ever you are in the world - (sign up incomplete); nor do we know year of your vehicle or whether auto or manual. This info, along with mileage and service history, may well be useful in connection with additional codes so as to narrow down the answer.

I'm sorry this isnt the definitive answer you were hoping for. It needs further diagnostics with additional codes. Code 84 will probably remain until the fault is resolved and the code is electronically cleared.

Additional comment: Some owners have reported that disconnecting the battery and allowing the system to disperse has sometimes reset the Code 84. You could try that.
Note : you should disconnect the negative first; and reconnect negative last.

Marie,

Do you have any further codes available yet or has the issue been resolved ?

Sorry to hijack this thread but in the interests of not starting yet another code 84 thread, my 11 automatic Orlando ltz ctdi is now permanently in limp mode. Took it on a run yesterday and as soon as I got on the motorway code 84 came up with the orange service light coming and going.
When I stopped at the next junction I put the car in neutral and the code cleared straight away. It of course returned on e I was up to 60 odd mph.
Is there a possibility code 84 could be triggered by a failing gearbox? It's just a hunch....
I'm close to dumping it back on the dealers forecourt but we love the car and if theres a way of getting it repaired without taking out a mortgage then I'm all ears.
The dpf light came on the day we got it but that went after a brisk drive. The code has been a regular sight ever since though.
Cheers all! ?

Hi all I hopein someone can help me I have just bought a automatic Chevrolet Orlando on a 2011 plate with 85k on the clock all seemed well for the test drive and when driving home it seems to be jolting when changing gears and is showing a error code of 84,
It has full service history with a major service done under 700 miles ago (what this consisted of I'm unsure as awaiting the garage to confirm tommrrow if possible )
Any ideas on what it could be

Gareth, On screen Warning code 84 is simply a Generic Code implying there is a problem that needs attending to but in itself does not define what. Exact DTC (Diagnostic Trouble Codes) need to be read with an OBDII reader.
You are therefore asking a question that is simply not answerable on the scant information given.

Without knowledge of OBD readings my guess (as it is an automatic) would be possibly insufficient/low level of ATF (Automatic Transmission Fluid), or that the fluid in there is burnt/cooked and no longer capable of providing protection for lubrication shift. Beyond this you need to be aware that certain gearbox variants on both Orlando & Captiva are known to be problematic for failure. Be prepared to exercise your right of cancelation of purchase contract if in doubt about the support you are given by your dealer. Do not allow the grace period to expire. Some dealers will string you along so as to exceed the notification period.

You havent completed your basic Sign-Up 'Location' (this is a WorldWide forum) but for now I'll assume possibly UK.

Hi
Aussie ed
It was a private sale so unsure where I stand with this but the gearbox seems to be jump when changing gears as this was my first though that it may just be low on atf
I tried sorting my location out yesterday as in south Wales uk

Hi Gareth, You'd be wise to get the ATF checked out PDQ. Your 'rights' under private sale are I think fairly limited but still worth checking out. Good Luck I hope a fluid flush & refill will fix it.

Location noted - thanks.

Additional tip which is helpful. You can add your vehicle details to your Footer (Signature) and they will automatically appear under your posts without you having to repeat it every time you post. This is helpful for Forum readers.
Example of my 'Footer' is below this post as an example.

Gareth,

I'm gutted for you.

Mackies of Glasgow specialise in repair /overhaul of Chevrolet Gearboxes.

There are previous posts mentioning them on the Captiva forum. You can read up previous posts by using the Index Topic Search function. Tools>Advanced Search>(topic)> Captiva.

The link for Mackies is :- https://www.mackie-transmission.com/

It may be that it only requires solenoid servicing rather than full rebuild. I'll keep my fingers crossed for you.

from my own personal experience I would suggest a new gearbox will be more than the value of the car.
I had a Captiva 2011 and the gearbox...some years ago now...was £9k to buy and fit (....thankfully done under warranty)
Did you purchase any warranty? ...or any handed over from previous owner?
As Ed notes....worth finding someone who can repair/rebuild
