Hi - I've been a very happy Ampera owner since late 2015 (second owner) ...I'm still happy - but I've a niggling problem (it might not be niggling) and that's the warning light that won't go away. My code reader says it's P0606 and Google describes it with a very broad brush so I don't know where to start. Having said that, I've recently replaced the 12v battery, I've checked as far as I can for any faulty earths, examined the fuel door and charge door and now I'm stuck.

So, has anyone got first hand knowledge of Vauxhall fixing P0606 - or better still any Ampera specific P0606 pointers I can follow.

Many thanks in advance.

check this link, looks like a software error, fix by reflashing the Inverter control module, NB the inverter is covered by the 8 year Voltec warranty

...many thanks for pointing me at the US site - it makes interesting reading.
I'm with my local dealer for a service on Wednesday of next week - I'll see what they say when I ask them to 'reflash the inverter control module'...
I'm still baffled as to why this 'problem' should occur ...what's gone wrong? ...or am I thinking mechanical whereas I should be thinking software?
The car has only 30k miles on it. My son in Texas has a Volt with 195k miles on it...
Anyway, again, many thanks for the info - I'll let you know how I get on.

It's not really complicated, everytime the elctronics operates it reads and writes data, there are error checks designed in, that say if everythng worked there should be a number in a memory location for example FF7 when it compares with what is expected and you get FF6 instead of FF7 that's when you get this kind of error. another possible cause is operating the systems at low voltages, in digital systems 1 and 0 are just 2 voltages, if you are in beteween it's difficult to determine if you are at 1 or 0.
These sort of errors are found in all computer system we just don't normally see them because they are corrected by error checking routines, Once the error can't be corrected a faiult will be reported.

So - it's Wednesday and I'm back from the main stealer having paid £361.88 for what is described as a main service. Here are the costs - labour £157.62, ...now their terminology: Filter Oil £4.95, Screw Oil Drain £14.10, Combination Filter £31.65, Filter Element £42.50, Washer Fluid £1.98, Brake and Clutch Cleaner £3.30 and 3.5 litres of Helix Ultra Pro AG 5W30 £45.47 ...plus £60.31 VAT.
As for the P0606 fault code, they confirmed that the code existed and turned it off and told me to take it to a specialist ...and then asked who'd looked after the car before this service. I told them that they did (they were originally one of the 23 Vauxhall centres that could deal with the Ampera) - to which I was told that they no longer supported the electrical aspects of the car and gave me their Customer Service number to find the nearest dealer that could help.
...turns out it's Bristol Street Motors at Waltham Cross - circa 60 miles away.

So, knowledgeable friends - what are the likely consequences of ignoring the fault code? ...and are we looking at a future situation where no one wants to be bothered with the Ampera?

Onwards and upwards

Cheers

I think support will becoe easier as more EV's come onto the market, HEVRA and other independants are starting up serivicing and fixing EV's and hybrids, once you're out of warranty VX become irrelevant.

As for P0606 there is nothing you can change or fix to be sure it does not return however these things are probabalist in nature so you may never see it again.

Black_amp ...again, many thanks for your thoughts on the matter (P0606) - and if I'm understanding what you write, the 'fault' doesn't matter as there's no definitive 'fix' for it - and even if there was a definitive 'fix' there would be no guarantee that it wouldn't return. So, should I bother with trying to get someone to 'reflash the inverter control module' ...or do I simply ignore the light?
As for future support for the Ampera, I agree with what you say, and look forward to not being ripped-off by VX in the future.
Thanks again.

You cannot ignore the light if it is the main engine warning light. If it is on, you car will fail it's MOT test.

...you are right about the MOT, but fortunately it just sailed through it's MOT just before the light came on - so, in effect, I've another eleven months to 'sort' it...

Have you tried clearing the code (using an OBD reader tool)? I know it sounds like hiding a potential fault - but these cars seem quite happy to throw spurious codes for a multitude of reasons. A serious fault will almost certainly throw another code anyway, so should be perfectly safe to clear the code a see what happens.

Modo - yes, I've cleared the code about three times but it's always come back after a few starts. I think it disappeared once of it's own accord when the car was started/running on petrol only. Might sound silly but I'm going to try and convince the car that the fault doesn't exist by removing the code every time it appears ...I've nothing to loose. I'll let you know how I get on as I can see the whole niggle taking a fair amount of time to get sorted.
...thanks.

Reflashing the inverter is pretty easy with a programming passthrough cable and access to GM SPS - any competent HEVRA garage will be able to do this...

Hugh - many thanks, that's just what I need to hear. My nearest HEVRA garage is close to the Vauxhall garage who used to be able to sort my car ...wouldn't surprise me if that where the Ampera VX technician has moved to ...so, as I went out in the car this morning I'd decided at some point (not today) I'll call in and see them. Anyway, getting in the car this afternoon and on start-up, the check engine light has gone out. I think it knows we've been talking about it!
...and as you say Black_amp, if it comes back (which it undoubtedly will) then it's a trip to the HEVRA member garage.
Again, many thanks for your inputs - I'll keep you informed as to how I get on.

Cheers.

It may be that the error has to occur a fixed number of times consecutively before it will throw the MIL. This could be why it is appearing, then you're clearing it and it is appearing after a set number of power-ups. I had a car that would show the MIL on every second startup after it was cleared.

...I think you are right - after clearing the check light I'd get a day or so before it came back on ...and I plug the car in to charge every time the car is at home - so, it can be started and stopped three or four times a day, each possibly with a charge.

Thing is, it's now gone out! ...it's been out for a couple of days - numerous starts and charging - and I didn't clear it; it did it of it's own accord...

So, I'm pleasantly perplexed, waiting for it to return ...or not.

And 'amusingly', as my wife was driving off in the Ampera this morning (Sainsburys) without the check light illuminated, I was starting the Merc Sprinter we have and (you've guessed it), the Merc check engine light started flashing... But it went off after the third start...

I think I'm being stalked by check engine lights...

As I said in my previous post these errors are probablistic, and they have a probability of ocurring or not. If the MIL is switched on by a probablistic error, it will turn itself off after a number of drive cycles without the error being seen. In some cases the reverse is true and the error needs to be seen more than once to turn on the MIL light. Generally it seems that you need 3 clean drive cycles to turn off the MIL I'm not sure what the drive cycle for the Ampera looks like for an ICE car you need to travel a cerrtain distance and exceed a minimum speed for a period of time, each manufacturer has a different cycle it seems

Black_amp - again, many thanks for your input. I've been trying to discover what the cycle is for the car but not had to many positive leads. I am surprised that the light has decided to disappear ...and I can't figure out any stop/start procedure that might have triggered this ...but I am please that it has gone.

So, having just tempted providence, and understanding that 'these errors are probabilistic', it wouldn't surprise me if it come back on ...but next time maybe I'll be more philosophical about it.

...again, many thanks.

...it's back on.
I managed to fix the Merc Sprinter (clogged EGR valve) so now I'll turn my attention (once again) to the Ampera - and report back.

Egr delete that sprinter if you can - sod the Nox, a diesel engine is designed to run on clean cold, boosted air...
