Thanks Robert, but it would be good if you could answer the questions asked. ‘Crankshaft bearing has failed….’. Um, sounds strange - there are many bearings on the crankshaft. Have they stripped this engine to come up with that diagnosis? Did you have any warning indications/ noises but this failure? This car is not long out of warranty. Have you had it long, have you seen the service history for it if not owned it from new? Regards, Gareth.,

Ouch. That's an expensive repair, and very surprising on a 4 year old car. Has it had a hard life, or the oil levels neglected perhaps?

Not necessarily. Instrument clusters are known to suffer failures which may be unrelated to the starting fault, hence my question about cranking from a jump start, and emphasises Magnet's request for detailed information. So far I think we are left with many possibilties that include: starter motor/wiring, ECM fault, defective battery.

Glad to hear the problem is solved and that you don't need yet another starter motor.

sorry the garage said the crankshaft bearing has failed so new engine needed

Unless I am missing something surely connecting the jump leads would at least illuminate the dash with ignition switched on, even if it did not manage to start the engine. I think maybe this is a bit more than a battery issue. Just my thoughts.

There will be a means of adjusting the intensity of the instrument panel lights - are you sure this hasn’t been set to minimum? Do you have both dip and main beam lights? When you say ‘flash’ do you mean the headlamp flasher doesn’t work? Regards, Gareth.

Welcome Robert, thanks for joining, and sorry to hear about your issue. To help Cliff and I, can you tell us whether the starter motor now cranks the engine over or not? If it does, we take it the engine doesn’t actually start now-? Regards, Gareth,

Hello Grant, Meaningful information and the results of advised tests are dribbling through slowly, but dribbling they are. Important :- Is this car a manual or an automatic? How did you measure the latest battery voltage? Was the engine on the jump start donor car ( what was it?) running at about 2,000 rpm when you attempted to start yours with it. Regards, Gareth.

I replaced the CCM in my '03 A6 C5 1.9TDI with one that had the identical part number a couple of months ago and it was completely plug and play. Your key fobs will need to be reprogrammed however, but it's a really quick and straightforward job if you have two. I posted a guide in the C5 forum that explains it step by step. Hope that helps you mate. Edit I've just noticed the CCM in your avant ends in an N and the saloon in a K, weirdly the one in my saloon is an N, go figure.

Can you ask them whether it was an engine earth cable or the positive feed cable to the starter?

UPDATE!!! the frayed wire was changed completely and seems to have fixed the problem. thank you for everyones help 🙂

haha hard to express emotions with no emojis

Sorry. No it did not crank the engine

That does not answer the question of whether the jump start cranked the engine.

"Engine failure" could mean anything from a broken ignition wire to complete seizure of the engine, and therefore tells us nothing meaningful. I suggest you get the car to a garage to have the problem diagnosed.

So took a battery reading 12.6v then 12.3 with the ignition on. Jump start from donor car did not work/change anything in the dash.

Grant. Did the engine turn over when you tried to jump start it? Rather than push the car to a garage why not call out a mobile mechanic and get him to test the battery, which is the most likely problem? 12 volts is too low for a battery in good condition.

I doubt it Richard. Any significant modification usually invalidates the warranty, whether it is related to the problem or not. For your sake I'd be glad to be proved wrong.

That was the first thing I did. But thanks.

engine was running.stopped at a junction start stop activated.went to pull away & engine died no warning lights on dash. RAC called & suspect engine failure.Anyone had this problem ? it's a 2021 plate with 49 000 miles

Ok so far. Iv test every fuse including both sets under the bonnet. Popped over seen garage he is of the similar opinion and said to test earthing. Iv test the earthing by jump lead from -at battery to engine block. I've tried to jump start the car the doner car wasn't very big tho. Iv ordered a large capacity jump pack and a newer charger. If that don't work I'll have to push it upto the garage. I've seen that you can manually get the car out off park. But that won't be till next week. Will keep feed upto date with progress. Thanks Grant

Has anyone got experience of having this replaced with TD1 registered? Work was approved then declined by local dealer as TD1 flag detected. I had EGR mapped out earlier this year after spending fortune replacing the intake manifolds. Dealer are saying it’s no longer covered under the 7yr warranty. I’ve escalated to Audi, not holding breath, but wondered if anyone else has had experience in similar situation.
