Electrical Fault Malfunction

[Hardip Singh]

Hello

Yesterday had a major problem with the A7.  Electrical system fault yellow warnng came up, before it turned red and its killed the engine and everything else.  

Can anyone advise if this is a known problem as been reading theres a lawsuit against Audi in the USA.

Urgently need some advise and guidance please as the cost to repair could be massive.

Thank you. H

I'd recommend getting a diagnostic check to see what fault codes flag up and go from there. What are they highlighting the issue is in the USA?

Yes initial diagnostic check by a mechanic friend said it the alternator.  A proper diagnositic person due to check it next week, with the aim of initially saving the 42/44volt battery as that replacement could be approx £4k!  He will also check for software updates and if any outstanding which should have been done by Audi direct.

New alternator looking at £3k for parts and labour, the part is a horrible £1400-1700 roughly.

Been trying to do more research on the matter in the USA (attached) plus anything else relevant to the UK.

Having spoke to the garage mechanic and a rescue towing service, they both informed me that they have seen plenty of these problems, its something that is happening due to the battery system not being suitable or is overly complicated.

So...can all Audi owners please check you are not due for a software update in the first instance, plus check what type of system you have to ensure you do whatever necessary to protect against major damage.  Please do not get into the mess im about to face.

Regards

Hardip

Look though this forum and you will find dozens of owners facing the same problem. Few have had a satisfacory resolution.
