Malc 565 Posted July 19, 2010 Report Share Posted July 19, 2010 Hi all this is my first post on this forum, so here goes !!I got my wife a 2002 Lupo Sport a couple of weeks ago and last week the warning light on the dash lit up! A mate of mine with a garage plugged in his diagnostic gizmo which displayed the code "16786 Exhaust Gas Recirculation system flow too high P0402". As we got 3 months warrenty with the car I left him with the details of said warrenty and I assume he is sorting out a quote for them, BUT driving home tonight the said warning lamp went OUT!!Does this mean the problem has cured itself? Will it return? Is this likely to be a problem until the valve is replaced?Any answers to any or all of these problems would greatly appreciated.

Defcon5 Posted July 19, 2010 Report Share Posted July 19, 2010 I have an intermittant fault with mine, plan on removing it, cleaning and refitting it at some point.I know on some cars they can be blanked off for better performance/throttle response, anyone know if that is the case for the Lupo?

LaydeeNina Posted August 3, 2010 Report Share Posted August 3, 2010 cleaned my egr valve and the light went permanently my boyfriend used carb cleaner... however i have since blanked it off and have noticed a slight increase in power, useless and not needed in my eyes, more trouble than their worth =) Quote Link to comment Share on other sites More sharing options...
jonnykell1980 Posted August 3, 2010 Report Share Posted August 3, 2010 an egr is designed to recirculate some exhaust gas into the cylinder to burn off any unburnt fuel to lower the emissions. the downfall of this the gas takes up room in the cylinder that could be used for a fresh mixture that will burn better therefore giving a slight bhp and torque increase if you blank it off. as for the fault they are generally just a solenoid valve which gets dirty and sticks, if youve got warranty get it replaced its probably intermittantly sticking likely to happen again.

RobG Posted August 3, 2010 Report Share Posted August 3, 2010 just had mine replaced, it would do the same thing, come on, go off, come on stay on, get reset by the garage, stay off for a bit, etc. I was bad and ran mine for a couple of months like that, then finally got it fixed. The car apparently smoked quite badly when they ran it once it had been replaced, but that cleared up after an italian tune up Quote Link to comment Share on other sites More sharing options...

SeatArosaJPR Posted January 14, 2011 Report Share Posted January 14, 2011 (edited) Hi, I hope someone can help me. Over a year ago the enigine management light came on in my Seat Arosa. I took it to the garage to have the issue diagnosed and they informed me that it was a fault with the EGR Valve. They quoted me a price to replace the part but at the time i did not have the funds so did some research and decided to leave the fault alone. I had the car MOT'd end of 2009 with the existing fault and it passed no problem. It has recently failed it's most recent MOT due to high emissions.Basically I'm trying to locate the EGR valve so i can clean/replace it myself.Picture of what i believe to be the EGR valveCould someone please tell me if this is the EGR valve and if so what is the best method for cleaning it.Thank you.

hazzap123 Posted February 26, 2014 Report Share Posted February 26, 2014 Hi, I've currently got 1.0 lupo and I have had exhaust emissions light on since about april last year, it was intermittent but now it seems to be perminantly on. I plugged it into laptop and it comes up with egr fault. I wondered how to fix it as its starting to annoy me now, i cant really afford to buy a new egr valve. I have heard about wynns egr cleaner, does anyone know if it works? also if not could someone tell me where about it is on my engine so i can take it off and clean it and also how to please. If anyone could help at all that would be great. Cheers Quote Link to comment Share on other sites More sharing options...

Davedex Posted March 1, 2014 Report Share Posted March 1, 2014 I've got the same problem and my EGR is only 4 years old! Spoke to vw to see whether they would offer me any goodwill and help towards the cost of replacement again but I might as well have bashed my head against a wall - they could not give a shiny sh**e!

red5racing Posted November 21, 2014 Report Share Posted November 21, 2014 The 1.0 AUC engine code has an EGR valve (PART NUMBER 030131503F which retails at almost £200) which are prone to getting blocked, the last of the AROSA had the 1.0 AUD engine which doesn't run an egr valve.
