I have to replace a rear parking sensor on my 57 plate 2.5 Tdi v6. The garage can fit a vw part which is £69 pound but will also happily fit an after market product. How do I know the part number in order to ensure compatability

 

Thanks

The part number is 3U0 919 275 B. You can find it though cheaper on EBay, original, new. Last time I bought it for ~ 30 Euro + shipping cost. You can search for this code on ebay.de, they have plenty of VAG original parts. Nevermind the language, just search for the part number.

Caution with ebay; many of them are actually clones from the Chinese market. The plastic casings look good but the actual sensor head is a joke and even worse quality than the originals.

You only really want to bother with a part coming in a VW box. If it is loose it is probably a knockoff.

In general you are right.

In particular, there are fewer fakes on German Ebay, compared to .com one. I installed mine few months ago and still works like a charm. Came with the part number stamped on it's body and compared side by side with the original from the car, identical. This was the link:

If you don't mind paying ~100 Euro for it, go for the original from the stealer...

That's the one I got, from the same seller. It was fake (well, it isn't the original by VW, that is sure). I confronted them about it and they refunded straight away.

Maybe they're selling original ones now, but when I bought it it wasn't.

The stampings on the side are not the part numbers... they are the specifications for the plastic!

Sorry, that was the wrong link (saved in my watch list since I was looking for sensors few months ago, but I didn't purchase from him - something must have turned me off, maybe reviews, don't remember), as from my mobile phone I didn't have access to my full ebay purchase history (only the last 60 days and this one I bought in September 2014).

 

The one I bought (I can see now from my laptop the full purchase history) is this one: http://www.ebay.com/itm/SKODA-SUPERB-3U4-PDC-PARKSENSOR-EINPARKHILFE-hinten-vorne-aussen-3U0919275B-NEU-/360978975155?pt=DE_Autoteile&hash=item540c0609b3 and you can see on the last photo of the item the part no written with white (actually you can see 3U0...) but this is what I got and it's still working. 

 

This doesn't change the fact that you can get all kind of fakes on Ebay, but for 30 Euro I took the chance, since the rest of the sensors were working (checked via VCDS), so I didn't plan to change the whole system. If I would have had 2 flawed ones, I would have gone for a system retrofit...

Nice one. The one I got definitely doesn't have the 3U... the sensor head actually fell out of it!

I think it is probably still not original, but perhap a better version.

I know it's already been answered, but in for a penny...

Could be so, but as long as it works is fine with me... Anyway, a bargain compared to the stealer's price...

Definitely!
