(now posted in correct forum thanks Spiny)


I've a 2014 Ampera which has now come down with the "buzzsaw" whine that other users have reported. Just happened the other day idential to the whining on the

The mileage is under 100,000 ; it's been fully serviced within the time periods and as far as I can see the Powertrain Warranty is still valid.


No problem says I, I'll take it into the local Vauxhall Dealership (Arnold Clark) after checking they do Electric Vehicles. One diagnosis later and they tell me it's
"noise seems to be coming from the gearbox area". They then recommend the gearbox is removed for inspection and referred to a transmission specialist.
Oh and it's not covered by warranty as the 8 year/100,000 mile warranty doesn't cover the gearbox.


I'd be grateful for any assistance here and confirmation that it is covered by the warranty. As far as I am aware the "powertrain" is covered from other posts including the gearbox/transmission.

I'd also be grateful for any thoughts as to how to get this resolved.
So far I have contacted Vauxhall direct and am awaiting them getting back to me but anything to assist me with Vauxhall / the dealer would be appreciated, as the dealer seems to be simply washing his hands of it and I ideally don't want to have to flatbed it to a specialist elsewhere (I'm in Scotland).



Thanks

Thanks - I think the issue is they are saying "gearbox/transmission" and it is - is this the "electric drive unit assembly" and how to convince the dealer of this.

Just out of interest Does anyone know are there any EV specialists who would know what they were talking ideally who have done this work under warranty?
Ideally North England (I'm presuming none in Scotland) which failing anywhere in the UK.

The electric drive unit assembly is the transmission they are referring to. It is covered by the 8 year Voltec warranty.

Bellingers have done several over the years as have others. there are several folks on here who have had this bearing replaced at various garages. Mine (touch wood) is still on its original one.

they really don't know what they are on about - do they service Ampera's? not EV's (Vauxhall ev's are now the PSA ones - corsa - mokup ) you can not send the transmission to a specialist like a manual or auto gearbox, - they would panic having the whole stack appear - motors, electronics and transmission in one lump.
Its a couple of hours apparently and needs a bearing and a new endcap.
this thread has the ampera dealers in the first post.

That should be covered as it’s part of the voltec system.
It’s part of the HV system, it’s not a gearbox.
If you took that to a gearbox specialist they would send it straight back,if you Google Chevy volt bearing replacement, there are videos of it.

Yes the transmission/gearbox assembly is definitely covered by the warranty and it should be repaired free of charge by an authorised Vauxhall Ampera dealer. ( Not all Vauxhall dealers can service the Ampera).
The transmission contains the following HV components.
Drive motors 1 & 2 and the Auxillary Pump and other HV components.
The thick orange wires you see under the bonnet are all connected to the transmission/gearbox and only HV trained mechanics should undertake this work.
The workshop maual can be seen at the following location and there is a clear diagram of the unit.

The bearing can be replaced without removing the gearbox. There was a TSB regarding the procedure. Ampera dealer will have this information.

Yes, the whole electric transaxle is covered.

But I have fought Vauxhall on this many times, sometimes on behalf of people here, and sometimes it works out and sometimes it does not.

You have a cast iron case to take to the motor ombudsman if Vauxhall don't honour their warranty commitment.

I have tried to get OLEV to take Vauxhall's refusal to honour warranty claims (it is part of the PIG conditions) but they couldn't give a fig either.

No-one cares.

It's why I sold mine.

But check this post out;-


The whole of the 4ET50 transmission is covered. Quote the reference number. Not that it will do you any good if they entrench.

Aye other than Arnold Clark the only other one that I still know of being authorised for the Ampera is Peter Vardy, Seafield Edinburgh. The only thing is their expert 'Charlie' who I have spoken to on a couple of occasions has now retired but last time I was speaking to him (2 years ago) he had been asked to consider coming back part-time or on an as and when required basis. Have a look at the last few posts of mine here this was the last time I was there and you can understand why. If you can get Charlie then you will be fine if you don't leave your car there for any length of time.
I meant to add that the only other one was in Inverness.

I had this happen to mine, I had the full dealer service history required by Vauxhall so it was covered under the 8 year warranty, I took it to Bellingers wantage and they replaced the main motor bearing. Has worked fine for 20'000 miles now. If no warranty It would have been £800.

OK Folks finally got this fixed for future use of anyone in the forum:-

1. High pitched whine is probably a Drive Motor Rotor Bearing Replacement. Ours had completely disintegrated so car couldn't be driven.
2. This is part of the EV Drivetrain and IS covered by warranty.
You will need your service book to show your servicing has been kept up to date for your warranty if it's a different garage - since GDPR there is no central service record.
3. My initial Vauxhall dealer sworn blind this wasn't covered by warranty - this wasn't true - don't take their word that the warranty is "only for the battery" - it isn't..
4. If you use a dealer that knows Amperas then they should be able to confirm the warrantly position. They will initially probably hedge their bets with "if it is the bearing it will be covered by warranty" at the existing diagnosis stage - this is fair enough as it is only when they do the work that they can access the bearing.
5. If you are outside warranty cost is roughly £800 - 900.

The easiest way to check it is covered by warranty is get them to look up the part / work on the Vauxhall part System and they should see something like this which shows that it is warranty part:-

" Drive Motor Rotor Bearing Replacement
Warranty coverage 8 years / 100000 mls 160000 km
0801369 High Voltage Disabling and Enabling
0801391 Drive Motor Generator Power Inverter Module Cooling System Draining and Filling "

Many thanks for all your help.

AV.
