Hi all.

I am looking for some advise/help fixing my better half's Corsa Easytronic (Auto)

Basically it runs fine when its cold drives ok etc but on the last few times its been used after 10-15 mins the engine looses all power and an F flashes on the gear display, the last time this happened an AA guy came out to the car and had a bit of a play with it and said the Auto module was playing up and towed me home.

I have been doing a bit of reading up on the net and found this place that rebuilds them http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=390100347118 but there is a few things i'd like to ask before i go taking it off.

First off, can i check the ECU fault code in a DIY manner like you could with the old Vectra b's and things like that (with the light flashing) or is it a main dealer job?

Then i have read its possable that the crank sensor could be to blame as its a simalar fault to a Cam/Crank sensor breaking down) but i was told by the AA guy it was the Clutch unit BUT!! knowing AA guys he may have been guessing? which brings me back to can i check the codes myself?

next, if it is the Clutch actuator thing i have been told that once the unit is taken off and repaired i would have to take it to Vauxhall to be blead and reprogramed? is this correct or as i'm using the origanal unit but rebuilt can i blead it myself?

As you have proberly guessed i'm not too flush at the moment and i'd like to do as much of this myself if i can to save some cash.

can anyone help?
Cheers,
Chris

Just checked the code and its come back as 1700 (P1700 SVS request via CAN B-06)

Can anyone tell me what this means? or asking for?

Also it only plays up when its warm, start it from cold and it runs/drives spot on, Five-ten mins of running and it won't select gears and the F comes on.

I've don quite a bit of searching and people are saying its either the Clutch actuator/Module or software issue.

Any ideas?

Is there anyone thats clued up on these easytronic gear boxed?

I've just spent a few minutes taking all the plugs off one bu one and spraying wd40 into them to get rid of any water that may have found its way in but its made no difference.

I have just read the P1700 fault could mean there is not a good connection on the back of the clocks? but i'm grabbing at straws now, i rang Vauxhall up and the guy on service was doing every thing he could to fob me off, so i am kind of stuck where even the expensive option is not an option at the moment.....

Is there anyone out there who has been in this position and can at least give me pointers?

No one??

Ok, Is there a main dealer who's really clued up on these? (I don't mind traveling if it gets it sorted) because my local VX main dealer don't want to know...

when 'f' flashes is means its picked up a fault in the system, it will need to go to a vauxhall dealer as these are complex box's. We've had a few customers with these and they can be very expensive to fix

It will usualy be the module, send it off to ecu-testing, i've used them countless times they are very honest if its not defective they wil return it for the cost of the postage and 10.

When you have the Module rebuilt does it need setting up afterwards by tech2?

Bit of a guess, but if it happens when its warmed up, sounds like a hardware issue at the gearbox end. The clutch actuator is buried between the engine and box and hard to get to and you'd obv need to bleed the system, the selector tower I think you may be able to get to. May be cheaper to get a box from a scrapyard and fit yourself rather than pay for vaux to fanny around with it, and end up charging for a new box anyway.

I've just taken it into a vauxhall main dealer and stood behind the guy who Tech2'd it and it came up with the same thing as i got P1700 and the guy turn round to me and said the Clutch Module is goosed..... Now do you think hes saying that from experience/guess or he saw some thing i didn't on Tech2?

I spoke to a mate i know about it who works at a main dealer (not Vauxhall) he said looking at the list of possible faults allot of them can be ruled out by using the symptoms. Going off that going of the asumption because it drives ok when cold the soft wear is ok and not needing setting up the first two faults that seem to have the right symptoms are...

P1701 Transmission Solenoid Malfunction - ??? Maybe ??


P1711 Transmission Fluid Temperature Sensor - Possable (need to look into this as it does play up more when its warm then cold)

Thing is i know the Module is coded to the car, but i'm told if i have it rebuilt i won't have a problem with the code but i'm under the impression i'd need tech2 to bleed the system afterwards? Is this correct or is it like the breaks where you can blead them yourself but Vauxhall recommend its done by them so they can open the ABS module to clear any bubbles??

I'm at the point where i'm thinking about sending the Module off to at least be tested by the Guys who rebuild them but i'm a little worried that because its intermitant it may not play up when there testing it??

The modules are electronics and may be coded, the bits that need bleeding are hydraulics so can't be coded, there should be generic solenoids, actuators etc. between the two.

Since it only happens when it warms up, i guess its safe to assume its not the electronics (as they'd either be permanently fooked or running fine unless they're litterally strapped to the radiator). So in theory you should be able to replace any broken part without recoding.

As far as I know there are no coded bits on the gearbox, the selector fork is controlled remotely, as is the clutch. There should be a remote transmission module somewhere else in the engine bay, or behind the glovebox maybe.

I'm sure the haynes manual will tell you how to bleed the hydraulics; you may have to look at one for a later model with easy tronic, as I believe this gearbox is omitted from the corsa c handbook.

Urm this is a little confusing, i have just been out playing with the car. I have been doing loads of reading up on this and one guy said smack the dash over the clocks when the F light appears, so i did that and the F goes and goes back into N and will move in gear about a meter or so then F comes back?

Problem is i've read so many threads etc i've forgotten where i saw it, but its odd?? it maybe a coincidence?? but i did it Twice and it seemed to work briefly? the next question is is there anything there that could possibly cause this sort of fault?

The thing is with bleeding the clutch how do you make it pump the fluid? is it a case of simply putting it in and out of gear? I think as you say i need to do some reading up on that.

OK, i was assuming the Module is on the side of the Clutch solenoid? It has two big Plugs going into the side of it but i've not followed them back to see where they go (but i will)

So if the Module is else where is this just to rebuilt the clutch Pump/Motor? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=390100347118&ssPageName=STRK:MEWAX:IT

Ok, This is looking like a fluke. I have just had another play with it and this time it couldn't decide where the Gear selector was (was displaying things like 3 where the N should be and 4 in 2 etc) but it has also started not showing anything, just a blank screen. Whilst all this is going on it would not drive and would only rev properly when the N was displayed.

Is this once its warmed up, or from cold?

Vxman

it runs fine for aprox 5-10 mins but then the longer you try and run it the worse it gets.

Vxman

After a bit of messing about the fault has been narrowed down to the Gear selector motors, it looks like they are seizing up which is why they only work for a short period of time before they warm up and start sticking.

:(

well i sent the two units off to be checked and rebuilt and i just got the call to say there is nothing wrong with them.......

After a quick chat with the tech guy there it would seem the fault code Vauxhall went off was caused by the recovery guy who came out when it first broke down unplugging the Clutch module with the battery still on, so now i've been told it can only be the Body control module or a soft ware bug.

Does this sound about right? and if its working Intermittently could it still be soft ware?

The other thing that has been pointed out is that this car has never had the Body control Module lid mod done to stop water leaks, there is a possibility it may have got wet if it does leak and we've not noticed?

Hi Vxman , Just wondered if you got an update on this prob and how its goin .....has it been solved yet ?? Got a similar prob with my Meriva , local garage has told me the fault code relates to the gear selector motor and waiting on their elec specialist havin a look and checking the motor out but cant help thinking (worrying!!) that its gonna be going in to Vauxhall for a mega bill ...

Yeh mines fixed now, tbh it was a nightmare because it was Intermittent so Vauxhall reset the codes and drove it and it would be fine then randomly it would throw up 6 fault codes which cover Body control module,Gear box Module,Clutch motor and the Gear selector module so it was quite a bit of messing about. Finally The guy at Vauxhall got board of me pestering and swapped some bits of a sales PX car they had in which found my fault. But as the Tech guy said he would have put money on it being the Body control module as there was so many things popping up and that would have been a 600 bill and wouldn't have fixed it, so you can see how it would have got expensive very quickly.

Thing is as well they are done in such a way where if you take the Clutch pipe off for any reason it needs to go to Vauxhall to be set up, i tried to be clever and take the Selector motors out and run it through the gears whilst opening and closing the Bleeder as i saw the Clutch being engaged but unfortunately no matter how much i messed with it it would not go in reverse and crunched going into first. Took the vauxhall tech guy 20 seconds to set the bite up and i got a 50 bill for it :(

So i don't know exactly what to advise you to do, maybe have the gear selector checked out first as they are temperamental and don't need resetting and if that doesn't fix it then go down the Vauxhall route, i'm sorry to say that if its not the Selector motors its going to pack a bit of a sting in the tale unless you get a bit of Luck.

Thanks for the reply vxman glad yours is up and running , could you clarify for me what part the fault was actually with when the vauxhall man swapped bits over? also what parts did you take off the car? was it just the selector motors off did you have the clutch module off and send away as well ? I have spoken to the tech guy at the ecu repair company you have mentioned and he has said that both parts are easy to remove (is that your experience?) and the clutch bleeding isnt usually a prob and can be done with an easy bleed kit- which sounds a bit diff to your experience . thanks again
