Hi guys,

First time posting to this forum so would appreciate any help or advice I can get.

I have the P2002 DPF code and an engine warning light, looking to replace the sensor first before anything else as I understand repairs can be costly so want to rule out the sensor before getting the EGR or DPF changed.

I have the code for the sensor which is 03L906051B however I can only find 03L906051D online, I read somewhere that this is the newer version of the part but wanted to make sure this would work on my car before I purchase the part. The other codes seem to be slightly different on the sensors too, would this matter? My car is a 65 plate so I have the newer shape and design compared the 2015 A4. I have attached some pictures too.

Many thanks in advance

Hello Lewis,

Welcome, and thanks for joining. 
The general opinion ties up with what you believe - the last letter depicting the latest version of the same part. 
As a matter of interest, what sensor brand are you intending to buy? 
Kind regards,

Gareth. 

Hi Gareth,

Thankyou for the quick response!

Perfect that's a great bit of information to know going forward regarding the letter being the latest version of the same part.

I intend to purchase a genuine VW part but I believe you can buy Bosch parts that work too? so far I have managed to find it on LLL parts here is the link VW/Audi Particulate Filter Sensor - Genuine VW/Audi 03L906051D . Do you have any suggestions on this? or do you know of any reliable places I could order the genuine part from?

Many thanks,

Lewis

Thanks Lewis, 

If you are talking about the sensor, then I’ve used Bosch sensors  ( not this particular application) to good avail in the past. If you are talking genuine VAG, then it’s worth contacting Audi Parts Direct at Cardiff ( part of Mon. Motors - once Cardiff Audi). They were/are giving discounts, and do mail order. Aberdeen Audi were again discounting some parts - now-?
Kind regards,

Gareth. 

Hi Michael,

 

Apologies for the late reply, thanks for the help with the sensors. I'm yet to change the DPS but now I have a few places to order the part from it will make the job easier.

 

Once again thanks for the advice and help!

Hi guys, been a busy year so far not had chance to update on the situation. 
 

In the end the EGR cooler was the problem, had it replaced and problem has been resolved with no re-occurrence since beginning of Feb. 
 

independent specialist did the job and took about 3 days in total, cost around £1200 with the labour and vat, labour was around half the cost. 
 

hope this helps someone else in the future
