My A5 tdi is 4 weeks and 2k miles old. Thus far the rad' to engine pipe has fallen off, necessitating a flatbed recovery; then the particulate filter light came on - because the car isn't very good at commutes which don't get the engine up to operating temp. (I didn't see a note in the sales blurb about that..) Now the glow plug and ECU lights are on and I'm awaiting another flatbed. 'Not impressed' is the restrained sentiment. Anyone experienced similar?

Eagle,

I Hope this is a one off to be frank! No consolation for you I know, but I haven't heard of anything quite so bad looking round various Audi forums. I guess there's always some failure rate with any sample of new cars, it thankfully looks pretty low for Audi, but there's always someone out there with a sorry tale like this. We all just hope it doesn't happen to us.

Just have a look at Swadman's leather seats in the thread on that subject!:eek:

As a piece of advice, start writing down somewhere all the dates and nature of each failure so that if this carries on you have a stronger case for rejecting the car and getting a new replacement from your dealer. Also record any costs you incurred (hire car/loss of work etc.) and exactly how long the car was off the road each time.

Good luck!

Scratch,

Thx for the advice. It would appear that this is not an isolated incident. My service engineer let slip that another A5 which was being used for 15 minute journeys suffered a similar fate; the driver was advised to take a longer, open road route to work! The secretary of the London dealer mine ended up at volunteered that mine was the first A5 with the problem but that several A3's had been in.

My service manager has now said I should have been asked what kind of driving I did and told that the DPF is prone to blocking in city congestion-driving, resulting in ECU limp mode and a low-loader if the car isn't quickly run at 50mph+ for 20 mins. Difficult in London.. Apparently, new sales booklets are also being printed with warning information.

If it happens once more it's a money-back situation and a different model - one that works in town..

I hope that, given this could become a major problem for Audi (you can't sell a car that can't do town driving, certainly not without telling the buyer) one hopes they will find a fix.

I think it would be very useful if folks could add any similar experiences to this thread. Safety in numbers and all that..

I just don't understand why manufacturers insist on the DPF's route to cleaner emissions. In some cases, Peugeot for example the filter can be cleaned and reused, but for many its a frustrating and expensive problem that will haunt owners long after the cars are out of warranty. I cant see a solution for you with the A5, if you're not doing the kind of sustained higher speed driving needed to burn off the filter then this will keep happening and Audi will not be able to to prevent it.

Renault took certain model Scenics back from owners who's filters kept blocking and replaced the cars with a different non FAF equipped car.

I assume it was EU pressure thats forced the manufacturers down this route, but surely to suggest someone needs to drive at high speed for up to twenty minutes a week to clean their filter is ludicrous...sorry to hear of your problems Eagle, seems a pattern of poor customer care is developing here...Hope Audi are watching..

Eagle not sure where you are based but sorry to hear about the problems- have you tried the new Shell Vpower diesel? I think this is "engineered" fuel so it is much cleaner than most fuel and I would expect has little or no particulates which might be the answer- also i have heard that Millers additive might help; let hope they diagnose and fix your problems to get you back on the road
