bigals Posted October 10, 2015 Share Posted October 10, 2015 Are there any sensors in the intercooler pipes that could be covered in oil,? If so worth a clean ? I had a similar issue where I had a sticky egr valve but also a tiny hole in the intercooler that allowed just enough oil into the air side of the system to clog the air flow/ temp sensor and made diagnosis even harder Quote Link to comment Share on other sites More sharing options...
Andrew O Byrne White - Ireland AO Posted October 10, 2015 Author Share Posted October 10, 2015 The MAF/temp sensor is right up at the air box, before the turbo so shouldn't have any oil near it. I replaced it when I had the problem first too. There was some oil in the pipes and intercooler so I'll take the EGR off this week and clean that. Hopefully thatll be all!

Kit Car Electronics Posted October 10, 2015 Share Posted October 10, 2015 Pull the plug off the egr valve and try that Quote Link to comment Share on other sites More sharing options...
Andrew O Byrne White - Ireland AO Posted October 24, 2015 Author Share Posted October 24, 2015 Finally got to the bottom of this. The split hose was in fact the only thing originally wrong. When I swapped out the MAF sensor before I found the hose, I replaced a good old part with a brand new faulty one so I've been chasing my tail for about three weeks now! Ah well, at least I have a nice clean intercooler, EGR, throttle body, boost control valve, MAP sensor..... that list could go on for a while. I think the lesson for me is not to buy unknown brand sensors that rely on extremely sensitive precious metals from ebay. Quote Link to comment Share on other sites More sharing options...
