Alternator part number for 2015 TDI Ultra 2.0 120ps

Hi,

I got the dreaded ‘alternator not charging battery’ message when driving home the other night gradually systems failed one by one then I spent 5 hours stranded by the side of the road waiting for the RAC.

I’m assuming the fault lies with the alternator itself -I will try and start her up and measure the voltages, but I need to fix it sharpish.

I’m having a terrible job trying to find the correct replacement part though and Audi are not been helpful; they can get me a part for £700 + a cover charge for exchanging the unit but say it will take 10-15 working days as it’s a non-stock item.

ok, so I asked them for the part number and they practically sneered at me. All they would tell me was it’s a VALEO unit and is rated somewhere between 120 and 180 amps.

I looked in Erwin as I hoped that might give me the info I needed but, alas, no.

Other than removing the old one and checking, is there any way of finding the part number or parameters for this ?

As it’s now completely dead, I can’t even get VCDS onto it to interrogate until I can get a wee bit of juice from a helpful neighbour.

Has anyone had this before ? Is there anything other than the alternator and battery I should check ? Does anyone happen to know the part number ?

thanks in advance for your help

What is the VIN?

Hi its: WAUZZZ8KXFA158031

I got the 'Alternator not charging' warning before the battery drained.

I think the battery itself is likely ok.

VCDS said the 'generator' was not electrically ok with a field current of 0 amps

All happened quite suddenly.

Thsankds for your help, I really appreciate it !
