Parking Sensors - again!
 

:mad:

A little while ago I replaced a front parking sensor with a unit from A8 Parts. Then, a couple of weeks later, I started to get an intermittent fault where the front sensor sound would come on continuously when the car was put into reverse. Had it VagCom'd at A4 Audi and they found nothing.

But it became more frequent and, assuming that the continuous sound of the front sensors meant a front sensor fault, I ordered a front sensor, had it painted up at A4 Audi and went to get it fitted. Then the VagCom said it was 2 rear sensors that were faulty! £49 for a front sensor I didn't need.

Back the following week to get 2 rear sensors fitted.:( And the rear ones are more expensive - why?

All fine for a few days......then the same bloody fault started again!

I see more of Andy at A4 Audi than I do of my wife - anyone know what's going on?

I'd suspect the parking sensor controller in that case. One or two, I could see, but given the number of failures you've had, it's either really bad luck, or the controller.

Shouldn't that show up on the VagCom?

Not necessarily... Depends on how it's failed.

Given that the controller for a D3 was under 100 quid (I had to upgrade mine to get the graphical display), I can't imagine that the D2 one is more expensive (or a8parts probably have one).

Hi,

I have a 2002 controller that I purchased beleiving mine was faulty but it turned out it wasn't and I don't need it.

Let me know if you are interested.

Yes, interested of course. But how did you determine that your's wasn't faulty, waht were the symptoms and what was the problem if not the controller? Is it a DIY fit?. Might be worth fitting to see? Could you PM me with a price?

Why don't you tell us? :ROFL:

Back again to see my friends at A4 Audi. But when I got there the parking sensors behaved fine! And no recorded faults. So it might be the controller - trying to get hold of frankow to buy his...the saga continues

A year on and I now own the car and the controller - but its still yet to be fitted ! Trouble is, I am not sure where it is located :o Can any one help?

what's the part number, as probably easiest to look that up in Etka and see which page it relates to!

I'm sure someone more knowledgeable will be along shortly who can tell you precisely in any case +++

Part no: 4D0 919 283

Looks like it's either in the boot or behind the back bumper - image attached may help +++

More helpfully, here's the instructions from elsawin to confirm it's under the CD changer in the passenger side storage....

Mines definitely down there, though it's a PF model. ;)

Many thanks both of you.

Moisture...moisture...moisture. Intermittent faults and operation...

I had a similar issue with my '98 S8. The controller turned out to be faulty, there was moisture once it was opened up. I purchased a used one, and it was fine. I dried the old one in my airing cupboard, in a cardboard box filled with silica gel.

I re-fitted the original controller a week later, and it worked perfectly, till I sold the car almost a year later. I sold the used one on eBay for much more than I paid for it in the first instance. ;)

That is a good point - the intermittent fault only occurred when the temp was 6decC or below. Having fitted the "new" the problem seems to have gone - but it has been warmer. There was evidence though of water / moisture ingress through the aerial grommet into that area of the boot although the inside of the controller was dry. I will keep the old one safe and dry till next winter!
