Egr valve adaptation

Looking for advice on egr valves. I’m on my second none genuine egr valve and I’ve not been able to get either of them to adapt. I’ve checked the part number and they are the same as the genuine pierburg valve. The genuine valve will adapt with no problem. Am I doing something wrong. I’ve followed the instructions on the Ross tech wiki. Any help or advice would be appreciated.

Hi David,

Where such questions are concerned, it's always helpful to state which engine you've got.

Cheers,

Tom
 
Another obvious question are you sure they are for the AUA engine and not some generic rubbish? VCDS Lite or full fat?

The obvious, but not, necessarily correct, thought is that the non OEM part is not even OEM spec.

Yes I think that may be the case. I may have to buy a pierburg replacement, but mine is an all metal Pierburg and the new replacements seem to be part plastic. I hope they are compatible.

They are for the Aua. Meant to be a replacement for the Pierburg OEM. VCDS Lite is the version I’m using but I’ve paid for greater functionality such as basic adaptation using measuring blocs 074.

Might fit but the part number on the original is 036 131 503 R whereas that finishes with the suffix M.

The last character indicates a later version, R is later version than M. If the rest of the number is the same, they should be backwards compatible.
Worth giving your local Seat, Skoda, VW dealer a shout, to get their price I'd think.

Called Crewe Audi for a price and they quoted £200, so I think I’ll buy a Pierburg from Amazon at £85. Hopefully this will adapt properly. Thanks for all the help.

Things to learn every day. EGR valve adaptation. http://wiki.ross-tech.com/wiki/index.php/Exhaust_Gas_Recirculation_(EGR)_Valve_Adaptation

My 1.4 petrol AUA has given me fault codes for too high EGR flow or too lean mixture ( 16555 / P0171 ) and it has been very annoying. When I have deleted the fault code the tick over / idle has been jerky or hunting between 600 and 800 rpm. (Disconnecting the EGR valve improves idle but of course gave an EML. ) Connecting the EGR valve again and after a little while when running with poor idle, the check engine comes on and idle stabilizes.

EGR valve nice and clean. Looking for leaks by pressurizing an inlet hose slightly while blocking the throttle body revealed nothing. Then I learnt about EGR adaptation. I ran the procedure above and I noted how the low voltage changed for one position. Now idle is stable and no EML, what a blessing.

By the way. As I made an oil change at the same time I noted how poor the threads in the oil pan / carter had become. VW says a new oil plug should be used every time. No chance that that would solve my issue. Rescue is to use a M15 x 1.5 tap and gently re-cut the original M14 x 1.5 thread as the M15 tap easily finds the way into the old threads, no drilling needed. After plenty of cleaning and flushing a new M15 x 1.5 plug was fitted.
