Engine management light on seems to be problem after problem not a good feeling

Inchindown · Jul 10, 2013

Sorry to hear about your woes.

Exactly which light is it that's come on? I can't see any mention of an engine management light in the owner's manual.

Hi Guys, a while ago I posted that a warning light was coming on occasionally. It was the orange engine outline with the large downward arrow inside. The manual says this means the engine is operating under reduced power. It seems to come on at speed and has become more frequent. My Antara is currently back at the dealer who is "trying to re-create the problem" Needless to say I know what the problem is... I just want it fixed!! I've got a feeling it will return and the first run I do the light will come on again!!
Howdey, is this the light that illuminates on your car?
Regards,
Kentara

Mine does this, pings and the light comes on for a few seconds then goes!

Also only does it when at speed!

Kentantara · Jul 11, 2013

Yup Robed2010 that's exactly what mine does. The service manager took it home last night to see if he could get it to do it for him. I'll post up what the dealership comes up with. have you had it checked out at all?

Hiya,

It did it ever since I first had it, never caused a problem, might happen once every two to three months so never really worried about it, plus I know they won't do anything unless the fault code stays on

Its the yellow engine block light its been on constantly since I posted this

Probably best speak to your dealer. You need to get the error code checked out.

Some code readers don't work on the Antara for some reason.

Ah ok cool found out its a provlem with auto transmition

Kentantara · Jul 25, 2013

Hi All, needles to say my car came back from the dealer and the fault happened again!
The dealer took it back and believes they have found the fault. It needs a new air flow meter apparently. On order from Germany and in the meantime the dealer has organised a hire car ( Astra ) for me all under the warranty bill so I can't complain really!!

Kentantara · Jul 29, 2013

Well my car is back with a new Air flow meter installed. Just given it a heavy run up to London and no problems!! SLM Vauxhall in St. Leonards seem to have fixed the problem for me!!

Grumps · Jul 29, 2013

Fingers crossed then.

Hi. I've had my 2013 Antara (auto) since February 2017. The car's engine management warning light keeps coming on. The car has had a replacement EGR valve and two throttle position sensors fitted but this has not cured the warning light issue.
I read your post which stated that the engine management light problem with your car related to the auto transmission. Can you give further information as to what that problem was please?

Victor · May 3, 2017

Well it's good to see that at least you searched the forum for an existing thread that was related to your problem rather than just starting a new thread.

I don't have an answer to your specific question but does your auto transmission in general behave itself? There's been some problems with the Antara (and Captiva) transmissions some even catastrophic failures which some say are down to weakness in the design. I'll see if I can find anything related.

Might be worth reading. Fuel type?

Are all these problems on automatic gearbox cars?

Dulac · May 3, 2017

I always thought that 'engine management' concerned the 'engine', exhaust and their electronic devices to make it function sweetly and not the gearbox, rear axle, etc. But I might be living in the Dark Ages. One would think that the battery was disconnected for the earlier investigations and a reboot wouldn't be necessary, but who knows?

It's often referred to as the Power-train Control Module that generally monitors the cars systems and I also feel that I belong in the dark.

If I can quote from Wiki:
A power-train control module (PCM) is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars there are multiple computers: the PCM, the Transmission Control Unit, and the Body Control Module, for a total of three separate computers as an example.

The PCM commonly controls more than 100 factors in a car or truck. There are many hundreds of error codes that can occur, which indicates that some subsection of the car is experiencing a problem. When one of these errors occurs, usually it will turn on the "check engine" light on the dashboard.

Engine Control Unit (ECU) is also called:
PCM: Power-train control module (Ford/GM)
ECM: Engine control module
Injection control unit (Peugeot,[2] Citroen, Fiat, Alfa, Lancia)
DME/DDE: Digital Motor Electronics / Digital Diesel Electronics (BMW,[3] Mini)
ECU: Electronic control unit

Loooooong way away from lifting the bonnet, checking the ignition timing, turning the mixture screw on the carb and getting it running right.
