So I have intermittent Check injection come on the dash. The first time it appeared was after I used a Code Reader to clear some airbag codes. I took the Map Sensors out, gave them a clean and it went away, only to return again after reading/clearing the codes again. Yesterday I fitted 2 new Map Sensors and it flagged Check Injection again. Didnt have to time to mess so had to leave it. When it shows Check Injection it goes into Limp Mode, limits revs and dont think it boosts. This morning turned it over and no Check Injection. Ran a check with a simple OBD reader I have and it shows the following: 'PO243 - Turbocharger Wastegate regulating valve A - circuit malfunction' The car has a 250 Turbo, Properfekt Recirc valve, 630 Injectors (done less than 500 miles). Any help or pointers very much appreciated. Thanks
So I have had the car scanned with CLIP. As feared, it is the Boost Solenoid, the n75 valve failing. Spoke to Renault, no longer listed!! Have read MK3 n75 can be fitted - has anynody fitted one https://www.kamracing.co.uk/renault-oe-n75-solenoid-valve-renault-megane-mk2-225-r26.html Thanks
