AudiLad Posted March 9, 2009 Report Share Posted March 9, 2009 Wondering if you guys could shine some light on this issue. I was driving back from work today on the motorway comofortably and I notice the 'Exhaust System' warning lamp (yellow) on. It's driving fine with no power lag at the moment. I've checked the manual and it states a seperate bit if its flashing but if its lit 'A fault has developed during driving which has redued the quality of the exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to the nearest qualified dealership. Have the engine checked. The following text is displayed in the combi-instrument display: EXHAUST WORKSHOP<' There is no message displayed, I've also checked 'Vehicle Status' on the highlight and nothing is displayed. I know I probably need to get a diagnostic done, how much are the stealers charging nowdays? Would it be worth going independent? Sorry for all the questions....appreciate your help guys!

billy2shots Posted March 9, 2009 Report Share Posted March 9, 2009 Had this before if i switched from v-power petrol to 95 Ron. When i filled with v-power it soon whent. If you use optimax already maybe you got some dodgy fuel. Could be something else but maybe its that simple. Link to comment Share on other sites More sharing options...

I've had the car about 3 months now and always used Shell V Power from the same garage, I'm pretty sure its not that. Thanks for the help though Link to comment Share on other sites More sharing options...
JonC Posted March 9, 2009 Report Share Posted March 9, 2009 'A fault has developed during driving which has redued the quality of the exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to the nearest qualified dealership. Have the engine checked. I had this once, but on my Alfa GTV. IIRC, it's the sensor in the exhaust which measures oxygen (I think) helping to determine if the air/fuel mix is right. A simple job to change it. I was worried about driving from the Highlands back to Edinburgh when I had my warning light come on, but it was fine to travel back the 180 miles to get it fixed. Didn't cane it on the journey home just in case, though Link to comment Share on other sites More sharing options...
AudiLad Posted March 10, 2009 Author Report Share Posted March 10, 2009 Cheers Jon, I've got it booked in to VW today but now doubting whether to go ahead just in case it is the lambda sensor? They are charging £50 for the diagnostics I presume and want the car the full day! But at the same time I would rather take it to VW so I can ask them to upgrade my ECU software, I don't know if its ever been done but it does have full VWSH Link to comment Share on other sites More sharing options...
AudiLad Posted March 10, 2009 Author Report Share Posted March 10, 2009 Just got back from Smith Knight Fay, when I got there I was told a lot of the mechanics are off sick and some have phoned in sick and your not booked in because the system crashed whilst we were booking you in!! Anyway they are going to do a diagnostics and get back to me, I have the latest ECU software they claim and gave me a printout... I'll keep you guys updated!

JonC Posted March 10, 2009 Report Share Posted March 10, 2009 Good luck and keep us posted. IIRC, I was only charged for the new probe and labour, but no diagnostics Link to comment Share on other sites More sharing options...
AudiLad Posted March 10, 2009 Author Report Share Posted March 10, 2009 Right...I got told the error was 08583 / P2187 fuel too lean on idle speed They said the first thing they need to do is change the Air Filter Housing which due to an incorrect shape and insufficient crimpin on the air filter element can cause a bypass. This bypass can cause air fluctuation which leads to the above faults being logged. I had my independent mechanic look at this later and the engine cover/air filter is really loose! The rubbers underneath have all broke and so have the clips holding the cover in place. He's 100% sure its this! Going to cry getting the bits tomorrow and installing. I'm determined not to let the stealers bend me over. Just one question, will I need to go back to reset the code logged or will the ECU recognise this making the light dissapear?

AudiLad Posted March 18, 2009 Author Report Share Posted March 18, 2009 Re-fitted Air flow housing correctly and cleared the code. 200 miles later the Exhaust Emissions (Engine Management) light has come on again! It is idling fine and performance is still great. I think it is my MAF but there is nothing to suggest this. I'll have to get it bloody diagnostic again...just when I started to get really pleased with the car! Link to comment Share on other sites More sharing options...
AudiLad Posted March 18, 2009 Author Report Share Posted March 18, 2009 I checked it today using Snap-On. The old error came up with 'System too lean at Idle Bank 1 Intermittent P2187' but the new one was 'Maximum RPM Limit Exceeded P0219 Intermittent' I was 'abit' heavy on the right foot yesterday 'playing' with a tuned Subaru. Anyway I've cleared the code for now, I was never expecting anything like this to happen. Anybody know what effect this code has? Link to comment Share on other sites More sharing options...
